訪問獲取在另一個應用的SQlite數據庫的值

1.假設在A應用生成了一個aaa.db的數據庫

2.在B應用怎麼訪問呢

public class ReadAXXXDB {
    public static int getSouceStatus(Context context,int sourceNumber) {
        Uri uri = Uri.parse("content://com.aaa.A/aaa.db");
        ContentResolver resolver = context.getContentResolver();
        Cursor cursor = resolver.query(uri, null, null, new String[]{"" + Number}, null);
        int status = -1;
        if (cursor != null) {
            for (cursor.moveToFirst(); !(cursor.isAfterLast()); cursor.moveToNext()) {
                status = cursor.getInt(cursor.getColumnIndex("status"));
            }
        } else {
            status = 1;
        }
        return status;
    }
}
