GCM取消注册导致应用程序崩溃 [英] GCM unregister causing the application to crash

问题描述

我在我的应用上实施了GCM通知。我现在试图在用户注销时取消注册应用程序。我正在使用下面的代码。当这段代码执行时，它会导致应用程序崩溃，使用以下logcat：

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.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

以下是代码：

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();
}

推荐答案

将支持库更新为25.0.0。
在更新下面的库之后，在应用程序gradle文件中，问题消失了。

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")
