Android project not working after updating project to Android L

Question

I just updated my android studio project to latest SDK version and its not working. Gradle sync is successful but app crashes on launch.

Here is the crash :

java.lang.NoClassDefFoundError: android.support.v7.app.ActionBarActivityDelegateICS
            at android.support.v7.app.ActionBarActivityDelegate.createDelegate(ActionBarActivityDelegate.java:47)

            at dalvik.system.NativeStart.main(Native Method)

Here are the lines in my dependencies tag in build.gradle :

compile 'com.android.support:support-v4:21.0.3'
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.google.android.gms:play-services:6.5.87'

My build.gradle - http://pastebin.com/NvrWZfEj

It crashes on MainActivity.java - setContentView(R.layout.activity_main); is the line — Faisal Memon, Dec 19 '14 at 20:35
"setContentView(R.layout.activity_main); is the line" -- no, it is not. You can tell that much from the stack trace. If it were `setContentView()`, then `setContentView()` would appear in the stack trace, and it does not. It *may* be `super.onCreate()`. I suggest checking out [this comment](http://stackoverflow.com/questions/17851783/error-implementing-support-library-action-bar#comment26065949_17853109) from a related Stack Overflow question and answer. — CommonsWare, Dec 19 '14 at 20:39
@commonsware so you mean that I am using something in my styles.xml which doesnt exists. How do I find which component is missing? — Faisal Memon, Dec 19 '14 at 21:01
I would start by removing all of them, so `AppBaseTheme` is empty other than its `parent`. See if your app runs. If it does not, then this isn't your problem. If your app *does* run, start putting things back in *slowly*, testing each time, until you start crashing again. — CommonsWare, Dec 19 '14 at 21:18
Try clean action on proj. Then rebuild it. Try remove and re-import, rebuild project. Show your build.gradle file content. — Robert Rowntree, Dec 22 '14 at 08:56
Tried cleaning - Here is my build.gradle http://pastebin.com/NvrWZfEj — Faisal Memon, Dec 22 '14 at 09:15

The problem is probably not in your code but in the build aka in the compilation so here is what I did to fix error message which were misguiding after an upgrade to 5.0 version

For me same problem was gone after recompiling the project with android 5 api 21

Choose project right click than alt-enter in eclipse compile with your device current os

Your normally get 'NoClassDefFoundError' when the Class you are using is available at compile time ; but not at runtime.

NoClassDefFoundError

So my guess is ; you are using the Emulator/Device (in which your application is Run), which has Android version different from Android L(the one you Compiled your code with). So believe you can either upgrade your emulator/device to Android L...or probably set the 'minSdkVersion'(in build.gradle) to resolve the InCompatibility Issues. Hope this helps.

I faced the same issue. Instead of trying to fix the old project, I removed the old project and started new one and copy pasted the legacy code one functionality at a time.

Sometimes, It is simply not worth figuring out why or what.

It will be very time consuming. Any other suggestion? – Faisal Memon Dec 30 '14 at 07:58
