    <p>I am new to android development. I have developed one app, now the problem is that whenever I rotate screen, app starts activity again and then its crashes application. I found some solution on google to use <strong><em>android:configChanges="orientation"</em></strong> . It works fine but when I rotate screen, its screen size does not change. How to solve this problem ?</p> <p>Logact :</p> <blockquote> <p>05-28 14:32:52.038: E/AndroidRuntime(276): FATAL EXCEPTION: main 05-28 14:32:52.038: E/AndroidRuntime(276): java.lang.IllegalArgumentException: View not attached to window manager 05-28 14:32:52.038: E/AndroidRuntime(276): at android.view.WindowManagerImpl.findViewLocked(WindowManagerImpl.java:355) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.view.WindowManagerImpl.removeView(WindowManagerImpl.java:200) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.view.Window$LocalWindowManager.removeView(Window.java:432) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.app.Dialog.dismissDialog(Dialog.java:278) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.app.Dialog.access$000(Dialog.java:71) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.app.Dialog$1.run(Dialog.java:111) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.app.Dialog.dismiss(Dialog.java:268) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.app.Dialog.cancel(Dialog.java:951) 05-28 14:32:52.038: E/AndroidRuntime(276): at com.MobileWeb.mytestbuddy.PremiumMain$TheTask.onPostExecute(PremiumMain.java:373) 05-28 14:32:52.038: E/AndroidRuntime(276): at com.MobileWeb.mytestbuddy.PremiumMain$TheTask.onPostExecute(PremiumMain.java:1) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.os.AsyncTask.finish(AsyncTask.java:417) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.os.AsyncTask.access$300(AsyncTask.java:127) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.os.AsyncTask$InternalHandler.handleMessage(AsyncTask.java:429) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.os.Handler.dispatchMessage(Handler.java:99) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.os.Looper.loop(Looper.java:123) 05-28 14:32:52.038: E/AndroidRuntime(276): at android.app.ActivityThread.main(ActivityThread.java:4627) 05-28 14:32:52.038: E/AndroidRuntime(276): at java.lang.reflect.Method.invokeNative(Native Method) 05-28 14:32:52.038: E/AndroidRuntime(276): at java.lang.reflect.Method.invoke(Method.java:521) 05-28 14:32:52.038: E/AndroidRuntime(276): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 05-28 14:32:52.038: E/AndroidRuntime(276): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 05-28 14:32:52.038: E/AndroidRuntime(276): at dalvik.system.NativeStart.main(Native Method)</p> </blockquote>

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).
