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 it is 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 a
          
           
            BroadcastReceiver
           
          
          component
         
         .  A pattern you can use to
 communicate from a BroadcastReceiver to a Service is to call
         
          
           startService(Intent)
          
         
         with the arguments containing the command to be
 sent, with the service calling its
         
          
           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 a BroadcastReceiver that has been registered with
         
          
           registerReceiver(BroadcastReceiver, IntentFilter)
          
         
         , since the lifetime of this BroadcastReceiver
 is tied to another object (the one that registered it).
        
| 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

         Determine whether the calling process of an IPC you are handling has been

 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
         
          
           checkCallingOrSelfPermission(String)

Returns an array of strings naming the private files associated with this Context's application package.
Return the context of the single, global Application object of the current process. This generally should only be used if you need a Context whose lifecycle is separate from the current context, that is tied to the lifetime of the process rather than the current component.
         Consider for example how this interacts with
         
          
           registerReceiver(BroadcastReceiver, IntentFilter)
          
         
         :
         
If used from an Activity context, the receiver is being registered within that activity. This means that you are expected to unregister before the activity is done being destroyed; in fact if you do not do so, the framework will clean up your leaked registration as it removes the activity and log an error. Thus, if you use the Activity context to register a receiver that is static (global to the process, not associated with an Activity instance) then that registration will be removed on you at whatever point the activity you used is destroyed.
If used from the Context returned here, the receiver is being registered with the global state associated with your application. Thus it will never be unregistered for you. This is necessary if the receiver is associated with static data, not a particular component. However using the ApplicationContext elsewhere can easily lead to serious leaks if you forget to unregister, unbind, etc.
Return the full application info for this context's package.
Return an AssetManager instance for your application's package.
Returns the absolute path to the application specific cache directory on the filesystem. These files will be ones that get deleted first when the device runs low on storage. There is no guarantee when these files will be deleted. Note: you should not rely on the system deleting these files for you; you should always have a reasonable maximum, such as 1 MB, for the amount of space you consume with cache files, and prune those files when exceeding that space.
Return a class loader you can use to retrieve classes in this package.
Return a ContentResolver instance for your application's package.
         Returns the absolute path on the filesystem where a database created with
         
          
           openOrCreateDatabase(String, int, SQLiteDatabase.CursorFactory)
          
         
         is stored.
        
| name | The name of the database for which you would like to get its path. |

Retrieve, creating if needed, a new directory in which the application can place its own custom data files. You can use the returned File object to create and access files in this directory. Note that files created through a File object will only be accessible by your own application; you can only set the mode of the entire directory, not of individual files.
| name | Name of the directory to retrieve. This is a directory that is created as part of your application data. |

| mode | 
           Operating mode.  Use 0 or

          object for the requested directory.  The directory
 will have been created if it does not already exist.
         
         Returns the absolute path to the directory on the primary external filesystem
 (that is somewhere on
         
          
           Environment.getExternalStorageDirectory()

         to this function, the returned
 file will be a path to a sub-directory of the given type.  Though these files
 are not automatically scanned by the media scanner, you can explicitly

         , which provides
 directories of media shared by all applications.  The
 directories returned here are
 owned by the application, and their contents will be removed when the

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

 start an activity instead of this function directly.  If you use this
 function directly, you should be sure to call

 to access it.

Register a 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.

 Prior to that, it would be ignored and delivered to all matching registered
 receivers.  Be careful if using this for security.
        
         Note: this method

           registerReceiver(BroadcastReceiver, IntentFilter)

         Broadcast the given intent to all interested BroadcastReceivers, allowing
 an optional required permission to be enforced.  This
 call is asynchronous; it returns immediately, and you will continue
 executing while the receivers are run.  No results are propagated from
 receivers and receivers can not abort the broadcast. If you want
 to allow receivers to propagate results or abort the broadcast, you must

Request that a given application service be started. The Intent should contain either contain the complete class name of a specific service implementation to start or a specific package name to target. If the Intent is less specified, it log a warning about this and which of the multiple matching services it finds and uses will be undefined. 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
         
          
           onStartCommand(Intent, int, 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
         
          
           bindService(Intent, ServiceConnection, int)

 running until
         
          
           stopService(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
         
          
           stopService(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.

 returned; else if the service does not exist null is returned.
         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

         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.
