App exits instead of going to next activity

I am calling an activity through a simple intent:

Intent startNewActivityOpen2 = new Intent(this, TransitionLandscape.class);
if (extras != null) {
        if (!extras.isEmpty()) {

           startNewActivityOpen2.putExtras(extras);
        }
}

startActivity(startNewActivityOpen2);

Does it matter that this current activity is also TransistionLandscape.class? The app exits (without crashing) when I start the new activity. Going through the debugger, the new activity is never called: (onCreate in is never called)

From the documentation, it seems that an activity can call itself.

Also, calling:

recreate()

instead of going to new activity, also causes app to exit (without a crash).

EDIT: Manifest

        <activity
        android:name=".TransitionLandscape"
        android:configChanges="orientation"
        android:label="@string/app_name"
        android:launchMode="singleTask"
        android:screenOrientation="landscape"
        android:windowSoftInputMode="stateHidden">
    </activity>

Actually, any activity that I call after TransitionLandscape causes the app to exit. Is it a memory problem?

Your app is crashing after that intent, as configuration changed is received.

12-10 21:08:23.520 543-600/? I/InputReader: Reconfiguring input devices.  changes=0x00000004
    Device reconfigured: id=2, name='elan-touchscreen', size 800x1280, orientation 0, mode 1, display id 0

can you try with 

android:configChanges="orientation|screenSize|keyboardHidden" />

There are other ways also to handle configuration changes you can check this link

Request you to please change below lines.

android:configChanges="orientation"

To

android:configChanges="orientation|screenSize|keyboardHidden" />

In your manifest file.

I think you should try deleting the "Adding Extras code block" to know that if problem start from it or you can also modify your TransitionLandScape activity a bit, for example deleting launchMode = "singleTask" tag in Manifest file, ... then run app again to check that did you solve the problem. It just my opinion and i am not good much at English, sorry if there is any grammar error.

it is not memory problem,

this line of your log clearly say's that you have problem when change orientation of activity (onConfigurationChanged())

WindowManager: Screen frozen for +74ms due to Window

in manifest file it will not allow to recreate activity on changing orientation of your device

try to change/set app orientation with code on recreate() method or in onCreate() method

setRequestedOrientation(Configuration.ORIENTATION_LANDSCAPE);

Use different names for your activities.
