Android app doesn't work on Android api level above 20

Question

Release build of an app is perfectly working on Android 4.0.3 and 4.4.2 which api levels are 15 and 19. But when I try to run it on android 5.0.1 and above it shows a grey screen only even without an appbar. I am using Google Maps, Microsoft Azure simple app and support library.

My manifest uses-permissions

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

And my manifest's uses-features

<uses-feature android:name="android.hardware.location" />
<uses-feature android:glEsVersion="0x00020000" android:required="true"/>
<uses-feature android:name="android.hardware.screen.portrait" />
