Cause: duplicate entry: AndroidManifest.xml- What seems to be the issue?

I also have the same issue with the AndroidManifest file.
The "Merged Manifest" tab shows this error
Merging Errors: Warning provider#com.telhum.chat.utils.MyFileProvider#android:authorities was tagged at AndroidManifest.xml:75 to replace other declarations but no other declaration present DreamsChat.app main manifest (this file), line 74

anyone has an idea whats wrong with this ? I have tried changing uses-permission to permission, where it had C2D_ it didn't work.

You may refer with this post.
Remove
<uses-permission android:name="${applicationId}.permission.C2D_MESSAGE"/>
<permission
android:name="${applicationId}.permission.C2D_MESSAGE"
android:protectionLevel="signature"/>
Run App then add the permisson again and Run App.
This problem often occurs when you try to install debug and release version of your app on the same device.

App not supported on some devices

My app doesn't support a specific android device (Samsung Galaxy Tab 3 10.1 P5210), though it supports other 10 inch tablets. I am clueless as to why this is happening. What could be the reason?
The client has the above mentioned tablet and my app doesn't get listed on his store.

</manifest>

In your manifest you are specifying that your app requires openGL ES 2.0:
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
Hence it will run only on devices that do.
It's the only requirement besides the Android version, therefore I guess your Samsung Galaxy Tab 3 doesn't.
Besides, you might want to change your package name from com.example.app to something else.

The problem was with the Camera Permission. When I removed that permission, my client's tab began supporting the app. But I still find it strange since the tab had both front and rear camera.

Try adding back the camera permission as you need it and specify the allowed screen sizes on the manifest. I reccomend you to add this code under uses-permissions tag for example...
<supports-screens
android:anyDensity="true"
android:resizeable="true"
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:xlargeScreens="true"
android:largestWidthLimitDp="2560"
android:compatibleWidthLimitDp="2560" />
Hope it helps!

You have not properly closed uses-permission tag
<uses-permission android:name="android.permission.ACCOUNT_MANAGER" />
<uses-permission android:name="android.permission.SEND_SMS" >
</uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" >

<service android:name=".GCMIntentService" />
**</application>
</uses-permission>**
That was closed at end of the page. remove that it will work

Check your package structure when giving value for android:name in activity tag.
For example :
If your package structure com.xxx.yy.app is like this and all your activities reside in app folder then you can give android:name=".yourActivityName" in activity tag.
If app folder has a subfolder and some Activities reside in that subfolder then you can give android:name=".subfoldername.yourActivityName" in activity tag.

My Issue will be resolve when I copy manifest from my project backup but I couldn't know why did occure this issue..
