Method Detail

onCreate

protected void onCreate(Bundle savedInstanceState)

Description copied from class: android.app.Activity

Called when the activity is starting. This is where most initialization should go: calling Activity.setContentView(int) to inflate the activity's UI, using Activity.findViewById(int) to programmatically interact with widgets in the UI, calling Activity.managedQuery(android.net.Uri , String[], String, String[], String) to retrieve cursors for data being displayed, etc.

You can call Activity.finish(boolean) from within this function, in which case onDestroy() will be immediately called without any of the rest of the activity lifecycle (Activity.onStart(), Activity.onResume(), Activity.onPause(), etc) executing.

Derived classes must call through to the super class's implementation of this method. If they do not, an exception will be thrown.

Overrides:

onCreate in class Activity

Parameters:

savedInstanceState - If the activity is being re-initialized after previously being shut down then this Bundle contains the data it most recently supplied in Activity.onSaveInstanceState(android.os.Bundle). Note: Otherwise it is null.

See Also:

Activity.onStart(), Activity.onSaveInstanceState(android.os.Bundle), Activity.onRestoreInstanceState(android.os.Bundle), Activity.onPostCreate(android.os.Bundle)

onClick

public void onClick(View v)

Description copied from interface: android.view.View.OnClickListener

Called when a view has been clicked.

Specified by:

onClick in interface View.OnClickListener

Parameters:

v - The view that was clicked.

onActivityResult

public void onActivityResult(int requestCode,
                             int resultCode,
                             Intent intent)

Description copied from class: android.app.Activity

Called when an activity you launched exits, giving you the requestCode you started it with, the resultCode it returned, and any additional data from it. The resultCode will be Activity.RESULT_CANCELED if the activity explicitly returned that, didn't return any result, or crashed during its operation.

You will receive this call immediately before onResume() when your activity is re-starting.

Overrides:

onActivityResult in class Activity

Parameters:

requestCode - The integer request code originally supplied to startActivityForResult(), allowing you to identify who this result came from.

resultCode - The integer result code returned by the child activity through its setResult().

intent - An Intent, which can return result data to the caller (various data can be attached to Intent "extras").

See Also:

Activity.startActivityForResult(android.content.Intent, int), Activity.createPendingResult(int, android.content.Intent, int), Activity.setResult(int)

checkExternalMedia

public boolean checkExternalMedia()

checks if there is read and write access to device storage

Returns:

true if media has both RW access false otherwise

write_to_file

public void write_to_file()
