But app installs and correctly work on the above android.
How can I fix this error
I also add the below code on the manifiests.xml and didn't get any result

I already enabled multiDexEnabled truein my gradle. Need some help to resolve this problem. Thank you.

Add below link under dependencies tag :
compile 'com.android.support:multidex:1.0.1'
Sync and run...

In build.gradle file
dependencies {
...
//Multi Dex
compile 'com.android.support:multidex:1.0.1'
....
}
In sample application class
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(SampleApplication.this);
}
then clean & build project

compile 'com.android.support:multidex:1.0.1'
worked for me...
am trying to run application from mac ( was build on windows ).
It crashes on app launches.
Thanks all..

I have enabled multidex in gradle file as well as extended MultiDexApplication in Application class
Also added multidex dependecy in gradle file
please help me to resolve this issue.

Ok Guys, after many try i found that you can not add dependencies on aar files. you have to include jar for each dependencies.

This crash occurs mostly on Android versions 4.4 and 4.2.
This answer suggests that this crash occurs when the apk is updated by dalvik. It seems to be a low-priority Android bug.
Are there any workarounds for this?
Does it help to set
<application
android:allowBackup="false"
in Manifest.xml?
(Maybe the backup of application is stored on SD-card, which is causing the problem on apk update).

This error usually occurs when you declare a class extending Application (android.app.Application) and then user android:name="thatClassName"
But if your App can't access it class fully. This error can occur
Try Making the class public only
It will make the application user that class globally

Android Studio - Unable to resolve class L after upgrade

I've recently upgraded my tools and build.gradle to version 21 in Android Studio.
My apk now crashes on load and I get the following error:
Unable to resolve superclass of Lcom/mypackage/MyClass;
Link of class 'Lcom/mypackage/MyClass
Is anyone experiencing similar issues?
I've tried the following but no success:
Cleaning the project
Restarting android studio
Re-importing the project

I later found out that this was an issue relating to multi dexing.
I needed to run a script to generate the names of the files for my main-dex-list
The blog post below has a detailed outline of this: http://blog.osom.info/2014/10/generating-main-dex-list-file.html
