Question

I am developing a tablet app. Everything is working fine until device is locked. Once the device is locked and rotated, then the force close appears.

I forced my app to run on LANDSCAPE mode only. So I mentioned this permission in the menifest.

 <activity
            android:name=".activity.LoginActivity"
            android:screenOrientation="landscape"
            android:windowSoftInputMode="adjustPan" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

So when I am locking my device and its rotated then the orientation changed and this force close generated.

To resolve this, I added this permission in the menifest.

android:configChanges="orientation"

And in the code:

 @Override
    public void onConfigurationChanged(Configuration newConfig) {
        // TODO Auto-generated method stub
        super.onConfigurationChanged(newConfig);
        Log.i("Log", "Configuration changes called");
        int orientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
        // or = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
        setRequestedOrientation(orientation);
    }

I have also added this line in the onCreate()

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.i("Log", "OnCreate");
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        setContentView(R.layout.lyt_login_main);
                ........
                }

But still its not getting resolved. Please help me out to solve this issue.

This is the error I am getting:

Answer 1

As @kumar said in comment,

I kept all the layout in the layout folder from layout-large-land, changed the menifest permission from
android:configChanges="orientation" to android:configChanges="orientation|keyboardHidden"

Commented this method onConfigurationChanged(), commented this line too setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

And then I run the code.
this solved the issue of the force close, but due to orientation change, the onCreate() method called and and I was loosing the entered data into the editText,

So for this I override the onSaveInstanceState(Bundle outState) method to my activity class. And did following.

I was saving the entered data in the hashmap, so in the onSavedInstanceState(), i did this.

@Override
    protected void onSaveInstanceState(Bundle outState) {

        outState.putSerializable("hashMap", hashMapSaveToDB);
        super.onSaveInstanceState(outState);

    }

And in the onCreate() checked for the savedInstanceState like this…

if(savedInstanceState != null)
        {
            hashMapSaveToDB = (HashMap<String, ArrayList<String>>) savedInstanceState.getSerializable("hashMap"); 
        }

This solved the loosing of the data at the time of onCreate() called.
