Getting access to SQL in Broadcastreceiver

Question

In a BroadcastReceiver, I receive the number of an outgoing call.

I want to compare this phone number with numbers I stored in a SQL database.

Sadly I don't get access in the BroadcastReceiver to my database. In other Activitys it works fine.

Here is the code for the BroadcastReceiver:

    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();

        //[ getting "string phonenumber" (works)]

        mySQLiteAdapter = new SQLiteAdapter(context); 
        mySQLiteAdapter.openToRead();
        sqLiteDatabase = sqLiteHelper.getReadableDatabase();
        Cursor cursor = sqLiteDatabase.rawQuery("SELECT * FROM MYDATABASE_TABLE =" +    potatos, null);

        if(cursor.getCount() > 0) {

            cursor.moveToFirst();
            while(!cursor.isAfterLast()) {
                cursor.moveToNext();
            }
        }
    }
}

The Code in SQLiteAdapter

public SQLiteAdapter openToRead() throws android.database.SQLException {
    sqLiteHelper = new SQLiteHelper(context, MYDATABASE_NAME, null, MYDATABASE_VERSION);
    sqLiteDatabase = sqLiteHelper.getReadableDatabase();
    return this;
}

Make sure you're using the Context in the onReceive(...) method and NOT this.

The reason for this is that this isn't a Context within a BroadcastReceiver and you need one to get access to your database. It works within an Activity because an Activity is a Context

Also, make sure to fix your query which is incorrect and will fail.

Cursor cursor = sqLiteDatabase.rawQuery("SELECT * FROM " + MYDATABASE_TABLE + " where " + KEY_CONTENT1 + "=" + phonenumber, null);

Where KEY_CONTENT1 is the constant for field inside of MYDATABASE_TABLE for the phone number.

SQLiteAdapter mySQLiteAdapter;
@Override
public void onReceive(Context context, Intent intent) {
    mySQLiteAdapter = new SQLiteAdapter(context); 
    mySQLiteAdapter.openToRead();
    sqLiteDatabase = sqLiteHelper.getReadableDatabase();

    Cursor cursor = sqLiteDatabase.rawQuery("SELECT * FROM " + MYDATABASE_TABLE + " where " + KEY_CONTENT1 + "=" + phonenumber, null);
}
