    <p>My old SQLitedatabase wasn't working to well the way I wanted it to so I figured to delete my old DBAdapter folder and DBHelper folder and made a new Database from the ground up with 2 new tables,new column names and a new DATABASE_NAME but after I linked up everything to my app with the new Strings and Cursors I'm getting a nullpoint crash and I'm getting these errors in my logcat.</p> <p>UPDATE: I've changed the onCreate parameter to db and I solved the invalid tables error but now I have a Table "Players"(MyFirstTable) does not exist error.</p> <p>UPDATE:NEW LOGCAT</p> <pre><code>04-19 19:56:02.781: E/AndroidRuntime(9179): FATAL EXCEPTION: main 04-19 19:56:02.781: E/AndroidRuntime(9179): android.database.sqlite.SQLiteException: no such table: PLAYERS (code 1): , while compiling: SELECT _id, USERNAME FROM PLAYERS 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteConnection.nativePrepareStatement(Native Method) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteConnection.acquirePreparedStatement(SQLiteConnection.java:882) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteConnection.prepare(SQLiteConnection.java:493) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteSession.prepare(SQLiteSession.java:588) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteProgram.&lt;init&gt;(SQLiteProgram.java:58) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteQuery.&lt;init&gt;(SQLiteQuery.java:37) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteDirectCursorDriver.query(SQLiteDirectCursorDriver.java:44) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteDatabase.rawQueryWithFactory(SQLiteDatabase.java:1314) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteDatabase.queryWithFactory(SQLiteDatabase.java:1161) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteDatabase.query(SQLiteDatabase.java:1032) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.database.sqlite.SQLiteDatabase.query(SQLiteDatabase.java:1200) 04-19 19:56:02.781: E/AndroidRuntime(9179): at com.fullfrontalgames.numberfighter.DBAdapter.getUsername(DBAdapter.java:143) 04-19 19:56:02.781: E/AndroidRuntime(9179): at com.fullfrontalgames.numberfighter.Findfriends$1.onClick(Findfriends.java:39) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.view.View.performClick(View.java:4106) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.view.View$PerformClick.run(View.java:17052) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.os.Handler.handleCallback(Handler.java:615) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.os.Handler.dispatchMessage(Handler.java:92) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.os.Looper.loop(Looper.java:137) 04-19 19:56:02.781: E/AndroidRuntime(9179): at android.app.ActivityThread.main(ActivityThread.java:5059) 04-19 19:56:02.781: E/AndroidRuntime(9179): at java.lang.reflect.Method.invokeNative(Native Method) 04-19 19:56:02.781: E/AndroidRuntime(9179): at java.lang.reflect.Method.invoke(Method.java:511) 04-19 19:56:02.781: E/AndroidRuntime(9179): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:792) 04-19 19:56:02.781: E/AndroidRuntime(9179): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:555) 04-19 19:56:02.781: E/AndroidRuntime(9179): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>DBAdapter class</p> <pre><code> package com.fullfrontalgames.numberfighter;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
