Description copied from class: Context
Version of Context.sendBroadcast(Intent) that allows you to receive data back from the broadcast. This is accomplished by supplying your own BroadcastReceiver when calling, which will be treated as a final receiver at the end of the broadcast -- its BroadcastReceiver.onReceive(android.content.Context, android.content.Intent) method will be called with the result values collected from the other receivers. If you use an resultReceiver with this method, then the broadcast will be serialized in the same way as calling Context.sendOrderedBroadcast(Intent, String).

Like Context.sendBroadcast(Intent), this method is asynchronous; it will return before resultReceiver.onReceive() is called.

See BroadcastReceiver for more information on Intent broadcasts.

Specified by:
sendOrderedBroadcast in class Context
Parameters:
intent - The Intent to broadcast; all receivers matching this Intent will receive the broadcast.
receiverPermission - String naming a permissions that a receiver must hold in order to receive your broadcast. If null, no permission is required.
resultReceiver - Your own BroadcastReceiver to treat as the final receiver of the broadcast.
scheduler - A custom Handler with which to schedule the resultReceiver callback; if null it will be scheduled in the Context's main thread.
initialCode - An initial value for the result code. Often Activity.RESULT_OK.
initialData - An initial value for the result data. Often null.
initialExtras - An initial value for the result extras. Often null.

sendStickyBroadcast

public void sendStickyBroadcast(Intent intent)
Description copied from class: Context
Perform a Context.sendBroadcast(Intent) that is "sticky," meaning the Intent you are sending stays around after the broadcast is complete, so that others can quickly retrieve that data through the return value of Context.registerReceiver(BroadcastReceiver, IntentFilter). In all other ways, this behaves the same as Context.sendBroadcast(Intent).

You must hold the Manifest.permission.BROADCAST_STICKY permission in order to use this API. If you do not hold that permission, SecurityException will be thrown.

Specified by:
sendStickyBroadcast in class Context
Parameters:
intent - The Intent to broadcast; all receivers matching this Intent will receive the broadcast, and the Intent will be held to be re-broadcast to future receivers.
See Also:
Context.sendBroadcast(Intent)

removeStickyBroadcast

public void removeStickyBroadcast(Intent intent)
Description copied from class: Context
Remove the data previously sent with Context.sendStickyBroadcast(android.content.Intent), so that it is as if the sticky broadcast had never happened.

You must hold the Manifest.permission.BROADCAST_STICKY permission in order to use this API. If you do not hold that permission, SecurityException will be thrown.

Specified by:
removeStickyBroadcast in class Context
Parameters:
intent - The Intent that was previously broadcast.
See Also:
Context.sendStickyBroadcast(android.content.Intent)

registerReceiver

public Intent registerReceiver(BroadcastReceiver receiver,
                               IntentFilter filter)
Description copied from class: Context
Register an BroadcastReceiver to be run in the main activity thread. The receiver will be called with any broadcast Intent that matches filter, in the main application thread.

The system may broadcast Intents that are "sticky" -- these stay around after the broadcast as finished, to be sent to any later registrations. If your IntentFilter matches one of these sticky Intents, that Intent will be returned by this function and sent to your receiver as if it had just been broadcast.

There may be multiple sticky Intents that match filter, in which case each of these will be sent to receiver. In this case, only one of these can be returned directly by the function; which of these that is returned is arbitrarily decided by the system.

If you know the Intent your are registering for is sticky, you can supply null for your receiver. In this case, no receiver is registered -- the function simply returns the sticky Intent that matches filter. In the case of multiple matches, the same rules as described above apply.

See BroadcastReceiver for more information on Intent broadcasts.

Note: this method can not be called from an BroadcastReceiver component. It is okay, however, to use this method from another BroadcastReceiver that has itself been registered with Context.registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter), since the lifetime of such an BroadcastReceiver is tied to another object (the one that registered it).

Specified by:
registerReceiver in class Context
Parameters:
receiver - The BroadcastReceiver to handle the broadcast.
filter - Selects the Intent broadcasts to be received.
Returns:
The first sticky intent found that matches filter, or null if there are none.

registerReceiver

public Intent registerReceiver(BroadcastReceiver receiver,
                               IntentFilter filter,
                               String broadcastPermission,
                               Handler scheduler)
Description copied from class: Context
Register to receive intent broadcasts, to run in the context of scheduler. See Context.registerReceiver(BroadcastReceiver, IntentFilter) for more information. This allows you to enforce permissions on who can broadcast intents to your receiver, or have the receiver run in a different thread than the main application thread.

See BroadcastReceiver for more information on Intent broadcasts.

Specified by:
registerReceiver in class Context
Parameters:
receiver - The BroadcastReceiver to handle the broadcast.
filter - Selects the Intent broadcasts to be received.
broadcastPermission - String naming a permissions that a broadcaster must hold in order to send an Intent to you. If null, no permission is required.
scheduler - Handler identifying the thread that will receive the Intent. If null, the main thread of the process will be used.
Returns:
The first sticky intent found that matches filter, or null if there are none.

unregisterReceiver

public void unregisterReceiver(BroadcastReceiver receiver)
Description copied from class: Context
Unregister a previously registered BroadcastReceiver. All filters that have been registered for this BroadcastReceiver will be removed.

Specified by:
unregisterReceiver in class Context
Parameters:
receiver - The BroadcastReceiver to unregister.
See Also:
Context.registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter)

startService

public ComponentName startService(Intent service)
Description copied from class: Context
Request that a given application service be started. The Intent can either contain the complete class name of a specific service implementation to start, or an abstract definition through the action and other fields of the kind of service to start. If this service is not already running, it will be instantiated and started (creating a process for it if needed); if it is running then it remains running.

Every call to this method will result in a corresponding call to the target service's Service.onStart(android.content.Intent, int) method, with the intent given here. This provides a convenient way to submit jobs to a service without having to bind and call on to its interface.

Using startService() overrides the default service lifetime that is managed by Context.bindService(android.content.Intent, android.content.ServiceConnection, int): it requires the service to remain running until Context.stopService(android.content.Intent) is called, regardless of whether any clients are connected to it. Note that calls to startService() are not nesting: no matter how many times you call startService(), a single call to Context.stopService(android.content.Intent) will stop it.

The system attempts to keep running services around as much as possible. The only time they should be stopped is if the current foreground application is using so many resources that the service needs to be killed. If any errors happen in the service's process, it will automatically be restarted.

This function will throw SecurityException if you do not have permission to start the given service.

Specified by:
startService in class Context
Parameters:
service - Identifies the service to be started. The Intent may specify either an explicit component name to start, or a logical description (action, category, etc) to match an IntentFilter published by a service. Additional values may be included in the Intent extras to supply arguments along with this specific start call.
Returns:
If the service is being started or is already running, the ComponentName of the actual service that was started is returned; else if the service does not exist null is returned.
See Also:
Context.stopService(android.content.Intent), Context.bindService(android.content.Intent, android.content.ServiceConnection, int)

stopService

public boolean stopService(Intent name)
Description copied from class: Context
Request that a given application service be stopped. If the service is not running, nothing happens. Otherwise it is stopped. Note that calls to startService() are not counted -- this stops the service no matter how many times it was started.

Note that if a stopped service still has ServiceConnection objects bound to it with the Context.BIND_AUTO_CREATE set, it will not be destroyed until all of these bindings are removed. See the Service documentation for more details on a service's lifecycle.

This function will throw SecurityException if you do not have permission to stop the given service.

Specified by:
stopService in class Context
Parameters:
name - Description of the service to be stopped. The Intent may specify either an explicit component name to start, or a logical description (action, category, etc) to match an IntentFilter published by a service.
Returns:
If there is a service matching the given Intent that is already running, then it is stopped and true is returned; else false is returned.
See Also:
Context.startService(android.content.Intent)

bindService

public boolean bindService(Intent service,
                           ServiceConnection conn,
                           int flags)
Description copied from class: Context
Connect to an application service, creating it if needed. This defines a dependency between your application and the service. The given conn will receive the service object when its created and be told if it dies and restarts. The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed.

This function will throw SecurityException if you do not have permission to bind to the given service.

Note: this method can not be called from an BroadcastReceiver component. A pattern you can use to communicate from an BroadcastReceiver to a Service is to call Context.startService(android.content.Intent) with the arguments containing the command to be sent, with the service calling its Service.stopSelf(int) method when done executing that command. See the API demo App/Service/Service Start Arguments Controller for an illustration of this. It is okay, however, to use this method from an BroadcastReceiver that has been registered with Context.registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter), since the lifetime of this BroadcastReceiver is tied to another object (the one that registered it).

Specified by:
bindService in class Context
Parameters:
service - Identifies the service to connect to. The Intent may specify either an explicit component name, or a logical description (action, category, etc) to match an IntentFilter published by a service.
conn - Receives information as the service is started and stopped.
flags - Operation options for the binding. May be 0 or Context.BIND_AUTO_CREATE.
Returns:
If you have successfully bound to the service, true is returned; false is returned if the connection is not made so you will not receive the service object.
See Also:
Context.unbindService(android.content.ServiceConnection), Context.startService(android.content.Intent), Context.BIND_AUTO_CREATE

unbindService

public void unbindService(ServiceConnection conn)
Description copied from class: Context
Disconnect from an application service. You will no longer receive calls as the service is restarted, and the service is now allowed to stop at any time.

Specified by:
unbindService in class Context
Parameters:
conn - The connection interface previously supplied to bindService().

Context.bindService(android.content.Intent, android.content.ServiceConnection, int)

startInstrumentation

public boolean startInstrumentation(ComponentName className,
                                    String profileFile,
                                    Bundle arguments)
Description copied from class: Context
Start executing an Instrumentation class. The given Instrumentation component will be run by killing its target application (if currently running), starting the target process, instantiating the instrumentation component, and then letting it drive the application.

This function is not synchronous -- it returns as soon as the instrumentation has started and while it is running.

Instrumentation is normally only allowed to run against a package that is either unsigned or signed with a signature that the the instrumentation package is also signed with (ensuring the target trusts the instrumentation).

Specified by:
startInstrumentation in class Context
Parameters:
className - Name of the Instrumentation component to be run.
profileFile - Optional path to write profiling data as the instrumentation runs, or null for no profiling.
arguments - Additional optional arguments to pass to the instrumentation, or null.
Returns:
Returns true if the instrumentation was successfully started, else false if it could not be found.

getSystemService

Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.)

Specified by:
getSystemService in class Context
Parameters:
name - The name of the desired service.
Returns:
The service or null if the name does not exist.

                           int uid)
Description copied from class: Context
Determine whether the given permission is allowed for a particular process and user ID running in the system.

Specified by:
checkPermission in class Context
Parameters:
permission - The name of the permission being checked.
pid - The process ID being checked against. Must be > 0.
uid - The user ID being checked against. A uid of 0 is the root user, which will pass every permission check.
Returns:

checkCallingPermission

public int checkCallingPermission(String permission)
Description copied from class: Context
Determine whether the calling process of an IPC you are handling has been granted a particular permission. This is basically the same as calling Context.checkPermission(String, int, int) with the pid and uid returned by Binder.getCallingPid() and Binder.getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always fail. This is done to protect against accidentally leaking permissions; you can use Context.checkCallingOrSelfPermission(java.lang.String) to avoid this protection.

Specified by:
checkCallingPermission in class Context
Parameters:
permission - The name of the permission being checked.
Returns:
Returns PackageManager.PERMISSION_GRANTED if the calling pid/uid is allowed that permission, or PackageManager.PERMISSION_DENIED if it is not.

checkCallingOrSelfPermission

public int checkCallingOrSelfPermission(String permission)
Description copied from class: Context
Determine whether the calling process of an IPC or you have been granted a particular permission. This is the same as Context.checkCallingPermission(java.lang.String), except it grants your own permissions if you are not currently processing an IPC. Use with care!

Specified by:
checkCallingOrSelfPermission in class Context
Parameters:
permission - The name of the permission being checked.
Returns:
Returns PackageManager.PERMISSION_GRANTED if the calling pid/uid is allowed that permission, or PackageManager.PERMISSION_DENIED if it is not.

public void enforceCallingPermission(String permission,
                                     String message)
Description copied from class: Context
If the calling process of an IPC you are handling has not been granted a particular permission, throw a SecurityException. This is basically the same as calling Context.enforcePermission(String, int, int, String) with the pid and uid returned by Binder.getCallingPid() and Binder.getCallingUid(). One important difference is that if you are not currently processing an IPC, this function will always throw the SecurityException. This is done to protect against accidentally leaking permissions; you can use Context.enforceCallingOrSelfPermission(java.lang.String, java.lang.String) to avoid this protection.

Specified by:

                                           String message)
Description copied from class: Context
If neither you nor the calling process of an IPC you are handling has been granted a particular permission, throw a SecurityException. This is the same as Context.enforceCallingPermission(java.lang.String, java.lang.String), except it grants your own permissions if you are not currently processing an IPC. Use with care!

Specified by:

grantUriPermission

public void grantUriPermission(String toPackage,
                               Uri uri,
                               int modeFlags)
Description copied from class: Context
Grant permission to access a specific Uri to another package, regardless of whether that package has general permission to access the Uri's content provider. This can be used to grant specific, temporary permissions, typically in response to user interaction (such as the user opening an attachment that you would like someone else to display).

Normally you should use Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION with the Intent being used to start an activity instead of this function directly. If you use this function directly, you should be sure to call Context.revokeUriPermission(android.net.Uri, int) when the target should no longer be allowed to access it.

To succeed, the content provider owning the Uri must have set the grantUriPermissions attribute in its manifest or included the <grant-uri-permissions> tag.

Specified by:
grantUriPermission in class Context
Parameters:
toPackage - The package you would like to allow to access the Uri.
uri - The Uri you would like to grant access to.
modeFlags - The desired access modes. Any combination of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
See Also:
Context.revokeUriPermission(android.net.Uri, int)

revokeUriPermission

public void revokeUriPermission(Uri uri,
                                int modeFlags)
Description copied from class: Context
Remove all permissions to access a particular content provider Uri that were previously added with Context.grantUriPermission(java.lang.String, android.net.Uri, int). The given Uri will match all previously granted Uris that are the same or a sub-path of the given Uri. That is, revoking "content://foo/one" will revoke both "content://foo/target" and "content://foo/target/sub", but not "content://foo".

Specified by:
revokeUriPermission in class Context
Parameters:
uri - The Uri you would like to revoke access to.
modeFlags - The desired access modes. Any combination of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

                              int modeFlags)
Description copied from class: Context
Determine whether a particular process and user ID has been granted permission to access a specific URI. This only checks for permissions that have been explicitly granted -- if the given process/uid has more general access to the URI's content provider then this check will always fail.

Specified by:
checkUriPermission in class Context
Parameters:
uri - The uri that is being checked.
pid - The process ID being checked against. Must be > 0.

Description copied from class: Context
If the calling process of an IPC or you has not been granted permission to access a specific URI, throw SecurityException. This is the same as Context.enforceCallingUriPermission(android.net.Uri, int, java.lang.String), except it grants your own permissions if you are not currently processing an IPC. Use with care!

Specified by:
enforceCallingOrSelfUriPermission in class Context
Parameters:
uri - The uri that is being checked.
modeFlags - The type of access to grant. May be one or both of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
message - A message to include in the exception if it is thrown.

enforceUriPermission

public void enforceUriPermission(Uri uri,
                                 String readPermission,
                                 String writePermission,
                                 int pid,
                                 int uid,
                                 int modeFlags,
                                 String message)
Description copied from class: Context
Enforce both a Uri and normal permission. This allows you to perform both Context.enforcePermission(java.lang.String, int, int, java.lang.String) and Context.enforceUriPermission(android.net.Uri, int, int, int, java.lang.String) in one call.

Specified by:
enforceUriPermission in class Context
Parameters:
uri - The Uri whose permission is to be checked, or null to not do this check.
readPermission - The permission that provides overall read access, or null to not do this check.
writePermission - The permission that provides overall write acess, or null to not do this check.
pid - The process ID being checked against. Must be > 0.
uid - The user ID being checked against. A uid of 0 is the root user, which will pass every permission check.
modeFlags - The type of access to grant. May be one or both of Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION.
message - A message to include in the exception if it is thrown.

createPackageContext

public Context createPackageContext(String packageName,
                                    int flags)
                             throws PackageManager.NameNotFoundException
Description copied from class: Context
Return a new Context object for the given application name. This Context is the same as what the named application gets when it is launched, containing the same resources and class loader. Each call to this method returns a new instance of a Context object; Context objects are not shared, however they share common state (Resources, ClassLoader, etc) so the Context instance itself is fairly lightweight.

Throws PackageManager.NameNotFoundException if there is no application with the given package name.

Throws SecurityException if the Context requested can not be loaded into the caller's process for security reasons (see Context.CONTEXT_INCLUDE_CODE for more information}.

Specified by:
createPackageContext in class Context
Parameters:
packageName - Name of the application's package.
flags - Option flags, one of Context.CONTEXT_INCLUDE_CODE or Context.CONTEXT_IGNORE_SECURITY.
Returns:
A Context for the application.
Throws:
PackageManager.NameNotFoundException - if there is no application with the given package name
