Com.example 路径错误

Question

When I was releasing an apk on google play I had to use a different package name cause of "com.example". I tried this and I get crash after testing an application. Before that everything was ok. I can send a manifest.

There are my errors.

My classes

Answer 1

You are trying to get 0 index in the database. Every time you add a new Note its ID will be 0. So, change your database KEY_ID to AUTOINCREMENT.

String query = "CREATE TABLE " + DATABASE_TABLE + "(" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
                KEY_TITLE + " TEXT," +
                KEY_CONTENT + " TEXT," +
                KEY_DATE + " TEXT," +
                KEY_TIME + " TEXT," +
                KEY_PIES + " TEXT," +
                KEY_RASAPSA + " TEXT," +
                KEY_TEL + " TEXT," +
                KEY_ZDJECIE + " TEXT" + ")";
        db.execSQL(query);

Then check your cursor not null in

getNote()
