Android APP Database Connect

Question

i want to create a SQLLite Database with "openOrCreateDatabase". The problem is, that i get an error while creating a new table.

11-11 12:36:39.865: E/AndroidRuntime(1520): java.lang.IllegalStateException: 
database not open

This is my code:

public class MainActivity extends Activity {

 EditText playerName; Button submitPlayer; SQLiteDatabase myDB = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_main); playerName = (EditText)findViewById(R.id.playerName); submitPlayer = (Button)findViewById(R.id.submitPlayer); myDB = SQLiteDatabase.openOrCreateDatabase("/data/data/com.my.appname/mydb.db",null); try{ myDB.execSQL("CREATE TABLE IF NOT EXISTS player (playername VARCHAR)"); myDB.execSQL("INSERT INTO player VALUES('test')"); 

... ..

I added 2 lines in the manifest:

< permission-group android:name="android.permission-group.STORAGE">

< uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Whats wrong ?

Thanks a lot !

You shouldn't be accessing your database like this. And also you don't need storage permissions for /data/data, that's for sdcard. What you should be doing is using SQLiteOpenHelper to manage your db. Here's a tutorial to get you started
