    <p>I have several methods for getting a record in my app<Br> But for some reason this one keeps giving me FC ! I'm using the following method to get the Cursor :</p> <pre><code>Cursor c=helper.getRecordById(num); </code></pre> <p>Which is implemented as follows :</p> <pre><code>public Cursor getRecordById(int rowId) { String rowIDs=""+rowId; String SelectById = "SELECT id, OrderName, OrderLink, DateYear, DateMonth, DateDay, OrderPrice FROM Orders WHERE id=?"; String[] args={rowIDs}; return(getReadableDatabase().rawQuery(SelectById, args)); } </code></pre> <p>I have tried also without converting the Int to String but i just left it this way.. get the same error for both ways.</p> <p>Whenever i get to the following line :</p> <pre><code>String name=c.getString(c.getColumnIndexOrThrow("OrderName")); </code></pre> <p>I get the FC. The GetColumnIndex works just fine... i've tested it exclusively. But the getString throws the error. :</p> <pre><code>06-02 21:07:13.656: W/KeyCharacterMap(4329): Using default keymap: /system/usr/keychars/qwerty.kcm.bin 06-02 21:07:16.006: D/AndroidRuntime(4329): Shutting down VM 06-02 21:07:16.006: W/dalvikvm(4329): threadid=1: thread exiting with uncaught exception (group=0x4001d800) 06-02 21:07:16.026: E/AndroidRuntime(4329): FATAL EXCEPTION: main 06-02 21:07:16.026: E/AndroidRuntime(4329): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.Sagi.MyOrders/com.Sagi.MyOrders.DisplayRecord}: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 0 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.app.ActivityThread.access$2300(ActivityThread.java:125) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.os.Handler.dispatchMessage(Handler.java:99) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.os.Looper.loop(Looper.java:123) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.app.ActivityThread.main(ActivityThread.java:4627) 06-02 21:07:16.026: E/AndroidRuntime(4329): at java.lang.reflect.Method.invokeNative(Native Method) 06-02 21:07:16.026: E/AndroidRuntime(4329): at java.lang.reflect.Method.invoke(Method.java:521) 06-02 21:07:16.026: E/AndroidRuntime(4329): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 06-02 21:07:16.026: E/AndroidRuntime(4329): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 06-02 21:07:16.026: E/AndroidRuntime(4329): at dalvik.system.NativeStart.main(Native Method) 06-02 21:07:16.026: E/AndroidRuntime(4329): Caused by: android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 0 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.database.AbstractCursor.checkPosition(AbstractCursor.java:580) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.database.AbstractWindowedCursor.checkPosition(AbstractWindowedCursor.java:214) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.database.AbstractWindowedCursor.getString(AbstractWindowedCursor.java:41) 06-02 21:07:16.026: E/AndroidRuntime(4329): at com.Sagi.MyOrders.DisplayRecord.onCreate(DisplayRecord.java:48) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 06-02 21:07:16.026: E/AndroidRuntime(4329): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2627) 06-02 21:07:16.026: E/AndroidRuntime(4329): ... 11 more 06-02 21:12:16.126: I/Process(4329): Sending signal.

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.

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