我在Android studio中收到广播接收器的错误作为零点异常.我想收到GCM通知

概述我正在使用GCM在我的应用上收到通知.为此,我在登录时生成注册ID并注册.登录或注册过程后,它会抛出onRecieve方法的零点异常错误. 有时会发生此错误,有时不会发生. 这是错误的logcat. 01-15 12:26:02.935 22448-22448/com.simpler W/System.err: java.lang.NullPointerException: Attempt to 我正在使用GCM在我的应用上收到通知.为此,我在登录时生成注册ID并注册.登录或注册过程后,它会抛出onRecIEve方法的零点异常错误.

有时会发生此错误,有时不会发生.

这是错误的logcat.

以下是在登录时生成令牌的代码：

if (checkPlayServices()) {// Start IntentService to register this application with GCM.Intent intent = new Intent(SignInActivity.this,RegistrationIntentService.class);startService(intent);LocalbroadcastManager.getInstance(SignInActivity.this).registerReceiver(mRegistrationbroadcastReceiver,new IntentFilter("reg complete string"));}

解决方法 您需要在代码中包含localbroadcastmanger
