GCM: java.lang.NoClassDefFoundError: com.google.android.gcm.GCMRegistrar

Question

Please help, it's all the days that I work on this problem and used all possible solutions found on the web.

Requirements: Use juno eclipse, ADT 20 I have works with business GCM, I did a project a bit more complicated using the demo of Android developers (http://developer.android.com/guide/google/gcm/demo.html) And I realized that my application was in Crask each call class GCMRegistrar.

So I created a minimal exercise that will work if I unlock everything.

import com.google.android.gcm.GCMRegistrar;

    public class Manda extends Activity {

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_manda);

        crash --->  GCMRegistrar.checkDevice(this);

            // while developing the app, then uncomment it when it's ready.

            GCMRegistrar.checkManifest(this);

        }

I attach the screenshot of the min exercise I added the gcm.jar library and I did all I found.

I am a new user than I can not post img but I put a public link of bropbox https://www.dropbox.com/s/dyi0y4sppz4rcq3/img%20GCM%20problem.zip

As stated in Google's docs, you MUST add your AndroidManifast.xml file the following:

<service android:name="YOUR.PACKAGE.NAME.GCMIntentService" />

<receiver
            android:name="com.google.android.gcm.GCMBroadcastReceiver"
            android:permission="com.google.android.c2dm.permission.SEND" >
            <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="YOUR_CATEGORY_NAME" />
            </intent-filter>
        </receiver>

Make sure you put your IntentService class in the right package.

In addition, how did you add the gcm.jar to you project? You need to create a "libs" folder in your project and put the jar there

Dealr Yuval, I took the manifest from http://developer.android.com/guide/google/gcm/gs.html. I have only one package in my simply project. I think the problem in in the library... I added: Build Path --> Libraris--> and i added the jar....the libs folder there is in my project of Default... However i putted in this folder too... – alfo888_ibg Oct 04 '12 at 19:40
But does your classes are located in the same packages as the example? – Givi Oct 04 '12 at 19:43
In addition, it looks like a build path error, where did you locate the gcm.jar file? – Givi Oct 04 '12 at 19:43

Solution 1:

Check that you have put gcm.jar file inside libs and not lib folder.

Solution 2:

Mostly this is the problem.Follow below steps to resolve the problem:

Right click on Project->Build Path-> Configure Build Path and then Order and Exports
Now check the Android Private Libraries .The checkbox should check of required library.
Refresh ,Clean and Run..here you go!

The problem was my emulator without Google Apis (Google Inc). If you are using android emulator you have to create emulator with Google Apis (Google Inc).
