Android: attempt to write a readonly database

Ich habe eine sqlite-Datenbank-Datei, und ich bin nicht in der Lage zu Lesen und zu schreiben, die auf dieser Datenbank-Datei.
Ich bin mit diesem code:

fileIsExists = new File(Environment.getExternalStorageDirectory()
            + "/bbmp/bbmp2.sqlite");
    if (fileIsExists.exists()) {
db = SQLiteDatabase.openDatabase(fileIsExists.toString(), null,
                 SQLiteDatabase.OPEN_READWRITE);        
}

Diese werfen Sie folgenden Fehler:
