Landscape Mode change to portrait in Android

Question

I had an application of timer and my app should always be in LandScape mode. I am getting width and Height of my main layout in code. In manifest, I had used:

     <activity android:name=".MActivity"
                      android:label="@string/app_name"
                      android:screenOrientation="landscape"
android:theme="@android:style/Theme.NoTitleBar"
                android:configChanges="keyboardHidden|orientation">

And in activity :

layout = (LinearLayout)findViewById(R.id.Rishikesh);
        ViewTreeObserver vto = layout.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

            public void onGlobalLayout() {
                int finalHeight, finalWidth;
                finalHeight = layout.getMeasuredHeight();
                finalWidth = layout.getMeasuredWidth();
                Log.w("*************", "OnGlobalLayoutListener/ Footer height :"+layout.getHeight()+" Width :"+layout.getWidth());


            }
        });

It gives height and width in landscape mode. But when i lock my phone, It gives height and width in portrait mode. What I am doing wrong I don't know. I am working on ANdroid 2.1. Can anyone help me solving this.

Answer 1

The issue is that your application is not in foreground and other applications may request to allow portrait or only portrait.

You receive current global layout - which may be portrait. Probably you receive onPause() before screen is locked and onResume() when your application is back in foreground - if you don't want to get layout when not in background, simply use a bool to store if you're the foreground app.

Answer 2

check after removing "android:configChanges="keyboardHidden|orientation"
