Thank you

Use these code in the your Manifest.xml file (in your activity class) then the data will not change in the both modes (landscape or portrait).
android:configChanges="orientation|keyboard|keyboardHidden|screenSize|screenLayout|uiMode
OR USE SIMPLY THESE
android:configChanges="orientation|screenSize|screenLayout"

java.lang.IllegalArgumentException: View not attached to window manager
Means your Progress dialog not dismissed completly. So you need to check whether its null or not and showing or not. Also put it with try....catch statement.
try {
if ((myDialog!= null) && myDialog.isShowing()) {
myDialog.dismiss();
}
} catch (final IllegalArgumentException e) {
// Handle or log or ignore
} catch (final Exception e) {
// Handle or log or ignore
} finally {
myDialog = null;
}

Do I need to modify the build path in property?

I found same issue couple of days ago, Yesterday I have resolved this issue by:
By compile my project using 1.7. As crashlytics compiled in 1.7
Installing build-tool 20 from sdk manager.
Hopes it worked for you too.

IllegalStateException after coming back to a FragmentActivity

this is about a recurrent problem that I discovered my application is facing and is related to the use of a couple of DialogFragments. I'm targeting mainly platform level 8 devices so to use DialogFragments I had to use the compatibility library.
The problem itself happens whenever I get out of the application and them come back. Here's the stacktrace:

And here's my stripped-down-to-the-minimum MainActivity.
public class MainActivity extends FragmentActivity{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
...
public void showNewChannelFragmentDialog() {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
Fragment prev = getSupportFragmentManager().findFragmentByTag("dialog");
if (prev != null) {
ft.remove(prev);
}
ft.addToBackStack(null);
// Create and show the dialog.
NewChannelDialogFragment newFragment = NewChannelDialogFragment.newInstance();
newFragment.setContext(this);
newFragment.show(ft,"dialog");
}
}
The showNewChannelFragmentDialog() method is only called when the user selects a specific menu option, so I think the content of the DialogFragment itself is irrelevant here.
But you can see I do exactly what is shown here and it indeed works, the problem as I said earlier is whenever my application is being restored back to life once the user has left it.
Any suggestions? I'm considering dropping the fragments and just using regular Dialogs.

maybe it's not the one and only problem but you should call
ft.add(newFragment);
ft.commit(); //but at least this
at the end of your showNewChannelFragmentDialog() function.
