AdMob making my app crash in release version

i just added AdMob to my app. Everything seem to work well when i debug or install release version of app (HTC m7). The problem occurs on CHUWI VX2 device (esky82_tb_cn_kk, Android 4.4). It is very strange because on this device my App works in debug mode but doesn't works in release version. I try turn of pro-gourd but it doesn't help me.
Any one have idea for that?
my manifest
instruction inside my onCreate method:
mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.setAdListener(new AdListener() {
#Override
public void onAdClosed() {
super.onAdClosed();
mAdView.setVisibility(View.GONE);
}
#Override
public void onAdOpened() {
super.onAdOpened();
mAdView.startAnimation(fade_in);
mAdView.setVisibility(View.VISIBLE);
}
#Override
public void onAdFailedToLoad(int errorCode) {
super.onAdFailedToLoad(errorCode);
mAdView.setVisibility(View.GONE);
}
#Override
public void onAdLoaded() {
super.onAdLoaded();
mAdView.startAnimation(fade_in);
mAdView.setVisibility(View.VISIBLE);
}
#Override
public void onAdLeftApplication() {
super.onAdLeftApplication();
mAdView.setVisibility(View.GONE);
}
});
mAdView.loadAd(adRequest);

Logcat indicate this line (Main.java:450)
mAdView.setAdListener(new AdListener() {

what is this ?
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
what were you expecting? to hit both sides?
try this
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
and let the rest go

You are getting a NullPointerException on line 450 of Main.
Look at that line. Something there has not been initialised.

I solve my problem. This issue isn't connect with AdView. It was problem with project. I made small mistakes. I don't have this line
<?xml version="1.0" encoding="utf-8"?>
on the start of xml layout file. I don't know how it can event works.
I reboot device
I added missing line to xml
I clean project (Build > Clean Project)
I rebuild project (Build > Rebuild Project)
Then my apk starts work without progourd but crash when I enable this feature. So i find this solution
I configure progourd configuration file like this.

Android - Intent makes my app crash

I am creating an app on Android, which involves an Activity and a service. One of the components of the service is meant to send a signal to the MainActivity, which will execute some specific code. The problem is, trying to send the intent makes the app crash.
Here is the code that sends the intent. Note that it resides in the inside of a doInBackground function of an AsyncTask object, which resides inside the said service:
#Override
protected String doInBackground(Socket... client) {
Intent received = new Intent();
received.setAction("com.mycompany.Messenger.MESSAGE_RECEIVED");
sendBroadcast(received);
}
Note that if I comment out sendBroadcast(received), the app does not crash.
Here is the handler of the Intent inside MainActivity (which has the name ChatBubbleActivity in my app):
public class MessageReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(MESSAGE_RECEIVED)) {
String current_message = "Intent works!";
TextView textView = (TextView) findViewById(R.id.myText);
textView.setText(current_message);
}
}
}
And this is the declaration of the Receiver in manifest:
<receiver android:name=".ChatBubbleActivity$MessageReceiver">
<intent-filter>
<action android:name="com.mycompany.Messenger.MESSAGE_RECEIVED"/>
</intent-filter>
</receiver>
, inside the <activity> chunk.
What is it that I might be missing?
EDIT:New version of code based on answers, still crashing.

Do you want to start an activity or send a broadcast? I don't understand your code.
You are starting an activity from a background thread, that's not allowed.
In your AsyncTask, the method protected String doInBackground(Socket... client) is the only one that doesn't run in the UI thread.

When ever you want to start your Broadcast Receiver you don't call it as an acitivty
Your Method
Intent received = new Intent(ChatBubbleActivity.MESSAGE_RECEIVED);
received.putExtra("current", "Intent is working!!");
startActivity(received);
What it should be
Intent intent = new Intent();
intent.setAction("com.tutorialspoint.CUSTOM_INTENT");
sendBroadcast(intent);

Calling autoFocus() from parent Activity returns NPE

I have instantiated a fragment type that extends CameraFragment (and implements TabListener), and I am trying to call the autoFocus() from the the parent Activity. Calling autoFocus() from the fragment that extends CameraFragment works fine, but calling it from the parent Activity results in an NPE. I am listening for a onKeyDown() event in the main Activity, which works as expected as per the logcat. Here is my NPE trace:

I'm not sure what version of the code you are working on, but line 96 is a closing brace in the current CameraFragment.
The only way autoFocus() can crash with a NullPointerException is if cameraView is null, and the only way cameraView should be null is if onCreateView() has not yet been called. You need the fragment to be visible and fully created before you request auto-focus.

can not load native library

I am developing a epub reader application, when I am loading it it shows a error that the reader cannot load native library, below I am attaching the log cat of the file.

File write permission error in Android

I am writing a file to SDCard and set <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> it works good upto 3.x but on 4.0 it gives the below error.

Any help or suggestion?

Just guessing but did you probably have your phone still connected to the computer? This error might happen if your sd card is still locked as a usb device.
Hope this helped,

Latter on I discovered that the issue is device specific. I installed the File Manager app from Android market and it shows no write permission. It mean the Android OS implementation of that manufacturer do not provide write permission which is causing the issue.

Probably you have hard-coded the external storage directory and it works on particular devices.
Environment.getExternalStorageDirectory();
Posting your code will help much more than just the log.

You may check you've just updated your Android O/S, too. Some major change cause sdcard problem. For me, I update my Android O/S in SHV-E160K from 2.3.5 to 4.1.2 with Odin which is samsung firmware update application. And I faced problem.
My detailed error message is as follows :

The reason is 4.1.2 couldn't recognize file system in 2.3.5. I solve this formatting sdcard storage. format doesn't mean delete your personal information such as address, memo or history. After format, it works like magic.

This may help you.
I faced the same issue when writing the file on sdcard. I have set all required permission to write the file but i used file object like below:
Wrong :
File myFile = new File(Environment.getExternalStorageDirectory().getAbsoluteFile()+fileName);
Correct:
File myFile = new File(Environment.getExternalStorageDirectory().getAbsoluteFile(), fileName);
That means the path was wrong.
