How to avoid class not found exception in android - android

I am getting class not found exception on some android devices, it's happening only on some devices.
This is the call-stack i have got,
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.picframes.android/com.picframes.android.first}: java.lang.ClassNotFoundException: com.picframes.android.first

Any suggestions for resolving this problem, I could not reproduce this problem on my device.

On devices with which android version program works and where it doesn't work? I am not sure if this is the case but you probably get this error on older devices, is that right? You should make sure that all the functionality of your program is available on older systems. Use your manifest file:
<uses-sdk android:minSdkVersion="integer"
android:targetSdkVersion="integer"
android:maxSdkVersion="integer" />
to define minimum sdk version, and you will get errors in your code if you are trying to use features that are not available on the device that you target.

Anyone have any idea what to do?
Never used unity3d... also I don't know what's in your gradle files, so can't really say unless you give more information. However, you could try cleaning your project and rebuilding it. Go to Build -> Clean Project or use gradlew clean if you are comfortable with the command line.

Your APK file does not contain a class named tigris.code.oneallah.walid.MenuPage. Either the APK is missing the class, or ProGuard renamed it.
