storing android application data on SD Card

Question

Is there a way to store android application data on the SD card instead of in the internal memory? I know how to transfer the application sqlite database from the internal m

Answer 1

Here is another neat little trick. The Application has a number of methods which are called to acquire paths. In particular the application has the method getDatabasePath with is used by SQLiteOpenHelper to construct the path. A custom application class can override these methods to provide different paths including paths in the getExternalStorageDirectory.

The external storage is either application specific or public. There are methods, replacing the getExternalStorageDirectory mechanism, getExternalFilesDir() and getExternalStoragePublicDirectory() respectively.
