Flexible Modular UI in android as per Orientation Change

I am making app which on portrait mode shows fragmentA (containing Listview) and when in Landscape mode, it shows fragmentA and fragmentB(Listview and its corresponding description).It keeps on crashing,my hunch says either there is a fault in if-else condition in MainActivity or problem is in communication pattern.I request Everyone to please Help. Here is my MainActivity.xml
package com.example.prince.fragment_modularui2;
import android.content.Intent;
import android.content.res.Resources;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity implements FragmentA.Communicator{
String s;
Resources r=getResources();
String[] a=r.getStringArray(R.array.descr);
FragmentA fa;
FragmentB fb;
FragmentManager manager;
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
manager=getSupportFragmentManager();
//fa always present
fa= (FragmentA) manager.findFragmentById(R.id.fragment);
fb= (FragmentB) manager.findFragmentById(R.id.fragment2);
fa.setCommunicator(this);
}
#Override
public void respond(int data) {
Intent i=new Intent(this,AnotherActivity.class);
i.putExtra("index",data);
startActivity(i);
}
}
here is activity_main.xml in Portrait
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.example.prince.fragment_modularui2.FragmentA"
android:id="#+id/fragment"
></fragment>
</LinearLayout>
activity_main in landscape
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">

android:layout_width="wrap_content"
android:layout_height="wrap_content"

<fragment

From the stacktrace I gather that you are calling getResources() on a Context that is null. This makes sense because you are declaring your resources as a field like:
Resources res = getResources();
This gets executed before the activity is created but you can only call getResources() once the activity is created. So the solution is to declare your resources like:
private Resources res;
And in your activity onCreate method you do:
res = getResources();
This also means that you can't use the res variable until the onCreate method is executed. Generally it is better to not declare resources as a variable like that but rather declare your string array as:
String[] a;
and then in onCreate just call: a = getResources().getStringArray(R.array.desc);
One other tip I can give you is to name your variable clearer. A string array named 'a' is not very descriptive. You can call it something like descriptionArray to make it more clear.

All Unity APKS crash in an Android Phone

I build an android apps about naked 3d display with Unity. I run it in 4 android phones, it runs well. But when I run it in a naked 3d mobile phone, the apps crashed. And all the apps generated with Unity can't run in this phone, even the simplest scene in Unity. But the apps generated by Android Studio, it can run well. It really confused me!
Here is the Log when I run the app in this phone, the phone is PPTV KING 7S.

I think it's not the problem in my Unity program. Anyone has some solution to deal with the problem?

I believe this should have been fixed with the latest release of the Google Play services client library. Note that this is a fix in the client library and so you will have to update the library to the latest revision using your SDK manager and recompile your application.
for more details you can check this link
https://code.google.com/p/gmaps-api-issues/issues/detail?id=4862

Do you have an another Activity named Map? As I see in your manifest,
<activity
android:name="com.highway.highwaymechanic.Map"
android:label="#string/title_activity_map" >
</activity>
Likewise, there should be a similar tag for the MapsActivity in your manifest. I think this is the error.

it bugs out much sooner, missing some native assembly for x86 architecture:
W System: ClassLoader referenced unknown path: /data/app/com.highway.highwaymechanic-1/lib/x86
followed by:
W GooglePlayServicesUtil: Google Play services is missing.
To add the missing Google Play (incl. Maps) Services, wrote a how-to once (it's almost the same).
While that FragmentActivity requires an IntentFilter, else it cannot be launched, for example:
<activity
android:name=".MapsActivity"
android:label="#string/title_activity_map">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
</intent-filter>
</activity>

NullPointerException in background thread when attempting to call messenger

I'm testing a simple Android app that uses a Service, Thread, and Messenger. I noticed when I quickly start and stop the Service I sometimes get a NullPointerException and FORCE CLOSE. I debugged it and found out my Messenger instance is sometimes null and thus my handler does not get called. What am I doing wrong? Do I need to wait before restarting the Service?
OK it just now happened without the quick stop/start of the Service. So I am not sure how to reproduce this problem. It may occur randomly.
I can catch the exception and get rid of the FORCE CLOSE, but that does not solve my problem of my handler not getting called when the Messenger instance is null. I looked at the Services documentation section on Managing the Lifecycle of a Service, and I did not see any mention of having to wait before restarting a Service.
This is how I start my Service:
Intent backgroundService = new Intent(PlayAudio.this, com.marie.mp3player.BackgroundService.class);
backgroundService.putExtra(BackgroundService.EXTRA_MESSENGER, new Messenger(handler));
backgroundService.putExtra(BackgroundService.EXTRA_SONG, song);
startService(backgroundService);
This is how I stop my Service:
Intent backgroundService = new Intent(MP3Player.this, BackgroundService.class);
stopService(backgroundService);
And here is a logcat containing two NullPointerExceptions near the bottom:

It was suggested that I add the code where the NullPointerException occurs. Very important. In fact here's the whole thread where the exception occurs marked with an arrow and stars:
/*
* This is the ServiceWorker thread that calls messenger to pass messages
* and data to the PlayAudio activity.
*/
class ServiceWorker implements Runnable
{
public void run() {
// do background processing here... a simple message for now
// send a message to the handler defined in the PlayAudio
try {
Message msg1 = Message.obtain();
msg1.obj = "Song";
msg1.arg1 = song;
if (messenger == null) Log.e("(Messenger)messenger: ", "NullPointerException");
messenger.send(msg1); // <== *** EXCEPTION OCCURS HERE ***
} catch (RemoteException e) {
e.printStackTrace();
} catch (NullPointerException e) {
e.printStackTrace();
}
// stop the service when done...
// BackgroundService.this.stopSelf();
// Or use the unbindBtn in the MP3Player activity.
}
}
If anyone sees a mistake here that would sometimes cause my Message instance to be null I sure would appreciate an answer.

Marie, assuming that the rest of your service is as in your other question. Here is what happens and causes your NPE.
In onCreate you create and start your thread, but you extract messenger in onStart method. If your worker method executes before onStart, you get NPE. The order of them is random, so sometimes you get NPE and sometimes not.
