java - GCM Plugin for Unity, Could not find method GCMRegistrar.checkDevice -

i've seen posts before, none of solutions seem have worked me.

i downloaded/installed eclipse mobile(http://www.eclipse.org/downloads/packages/eclipse-mobile-developers/junosr2), , created android application, using instructions found guy's video tutorial(http://www.youtube.com/watch?v=tazeiionva0) make library can drop unity.

of course, tutorial mobclix, trying build gcm plugin, process similar. think have included dependencies need. in eclipse, in project see "android dependencies" includes: classes.jar(contains unity player hooks), gcm.jar , android-support-v4.jar. under "android 4.2.2" see "android.jar". under "referenced libraries" see classes.jar , gcm.jar. following other forum posts(such one: gcm : java.lang.noclassdeffounderror: com.google.android.gcm.gcmregistrar) error had manually copied gcm.jar , classes.jar "libs" folder(i using adt 17), selected add build path.

after of this, still see 2 errors when deploy test on device, first title error, followed noclassdeffounderror. i've gone through 3 devices compatibility, , i'm using motorola 2.3.3 on it(so should support gcm). if knows else causing please let me know. not familiar eclipse(or java matter), i'm betting it's in java project somehow.

the code simple 2 files

registeractivity.java:

package com.my_provider.gcm;  import android.os.bundle; import android.app.activity; import com.google.android.gcm.gcmregistrar; import com.unity3d.player.unityplayer; import com.unity3d.player.unityplayeractivity;  public class registeractivity extends unityplayeractivity {     public static string projectid;      @override     protected void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);     }      public static void registerdevice(final activity activity)     {         try         {             gcmregistrar.checkdevice(activity);             gcmregistrar.checkmanifest(activity);              final string regid = gcmregistrar.getregistrationid(activity);              if (regid.equals(""))                 gcmregistrar.register(activity, projectid);         }         catch(exception e)         {             unityplayer.unitysendmessage("errorhandlergameobject", "onerror", e.getmessage());         }     } } 

and lastly service gcmbroadcastreceiver.java:

package com.my_provider.gcm; import android.content.context; import android.content.intent;  import com.google.android.gcm.gcmbaseintentservice; import com.unity3d.player.unityplayer;  public class gcmbroadcastreceiver extends gcmbaseintentservice {      public gcmbroadcastreceiver()     {         super(registeractivity.projectid);     }      @override     protected void onregistered(context context, string deviceid)     {         unityplayer.unitysendmessage("deviceregisteringgameobject", "onregisteredandroiddevice", deviceid);     }      @override     protected void onunregistered(context context, string deviceid)     {         unityplayer.unitysendmessage("deviceregisteringgameobject", "onunregisteredandroiddevice", deviceid);     }      @override     public void onerror(context context, string errorid)     {         unityplayer.unitysendmessage("deviceregisteringgameobject", "onerror", errorid);     }      @override     protected void onmessage(context context, intent intent)     {         unityplayer.unitysendmessage("deviceregisteringgameobject", "onmessageandroid", intent.getstringextra("message"));     } } 

i had manually copied gcm.jar , classes.jar "libs" folder(i using adt 17), selected add build path.

i have no idea classes.jar is.

simply having gcm.jar in libs/ folder sufficient regular android app -- manually changing build path "add build path" mistake.

whether process unity plugin different, cannot say.

the error indicates have gcm.jar in compile-time build path (e.g., via add build path) not in apk (e.g., not have gcm.jar in libs/, or adding build path manually prevented being added apk).
