Conversion between Uri and file path

1. Conversion of Uri to file path

public String getPathFromUri(Uri uri){

Cursor cursor = getContentResolver().query(uri, null, null, null, null );

cursor.moveToNext(); 

String path = cursor.getString( cursor.getColumnIndex( "_data" ) );

cursor.close();

return path;

}

2. Conversion of file path to Uri

public Uri getUriFromPath(String path)

String fileName= "file:///sdcard/DCIM/Camera/2013_07_07_12345.jpg";

Uri fileUri = Uri.parse( fileName );

String filePath = fileUri.getPath();

Cursor c = getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 

null, "_data = '" + filePath + "'", null, null );

cursor.moveToNext()

int id = cursor.getInt( cursor.getColumnIndex( "_id" ) );

Uri uri = ContentUris.withAppendedId( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id );

return uri;

}
