GCM unregister causing the application to crash
android, google-cloud-messaging, java
Solution
I was with same problem after update the support library to 25.0.0 . For me after update the below libs,in the app gradle file, the problem gone.
compile("com.google.android.gms:play-services-location:9.6.1")
compile("com.google.android.gms:play-services-maps:9.6.1")
compile("com.google.android.gms:play-services-gcm:9.6.1")
Problem
I've implemented GCM notifications on my app. I am now trying to un-register the app when the user logs out. I am using the following code. When this code executes, it causes the application to crash with the following logcat: ``` java.lang.IllegalAccessError: Method 'void android.support.v4.content.ContextCompat.<init>()' is inaccessible to class 'com.google.android.gms.iid.zzd' (declaration of 'com.google.android.gms.iid.zzd' appears in /data/app/com.example.packagename-1/base.apk) at com.google.android.gms.iid.zzd.zzeb(Unknown Source) at com.google.android.gms.iid.zzd.<init>(Unknown Source) at com.google.android.gms.iid.zzd.<init>(Unknown Source) at com.google.android.gms.iid.InstanceID.zza(Unknown Source) at com.google.android.gms.iid.InstanceID.getInstance(Unknown Source) at com.zaryans.updatedepoultry.WelcomeActivity$11.onItemClick(WelcomeActivity.java:469) at android.widget.AdapterView.performItemClick(AdapterView.java:310) at android.widget.AbsListView.performItemClick(AbsListView.java:1145) at android.widget.AbsListView$PerformClick.run(AbsListView.java:3066) at android.widget.AbsListView$3.run(AbsListView.java:3903) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) ``` Here is the code: ``` InstanceID instanceID = InstanceID.getInstance(WelcomeActivity.this); try { instanceID.deleteInstanceID(); Utility.logCatMsg("Logged Out Success!!!"); } catch (IOException e) { Utility.logCatMsg("Exception while logging out: "+e.getMessage()); e.printStackTrace(); } ```
