    As I don’t have enough reputation to put a comment yet >.< I’m gonna put this as an answer instead.

    The stack trace contains this SQLiteDatabase created and never closed which leads me to believe that the database was never closed. I’m assuming that Android is griping about the three lines here
    db = this.openOrCreateDatabase(“location.db”, SQLiteDatabase.OPEN_READWRITE, null);
    d = new data(this,Geo_Create_Table);
    db=d.getWritableDatabase();
    and since thats all that you provided I think you think the same. If I understand what this is trying to do, you are opening a locally stored Database db and then, I guess d is also referencing the same locally stored Database. MAYBE (not too sure) that is causing the memory leaks in your app, but one thing I do know is that you need to add the db.close() in there somewhere.

    You could try the suggestion that this other user made by using a try {} finally{db.close()}
