我遇到的情况是,全新安装的 Android 应用程序在到达onRegistered
我GCMIntentService
文件中的函数后会崩溃。GCM 注册成功,我可以在下次打开应用程序时检索 GCM 注册 ID,但我不希望它在用户第一次打开它时崩溃。
我用它来要求注册:
GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
GCMRegistrar.register(this, getResources().getString(R.string.gcmToken));
}
这是我的GCMIntentService
文件
public class GCMIntentService extends GCMBaseIntentService {
private static final String LOG_TAG = "GCM";
public GCMIntentService() {
super( "###############" ); // use my GCM ID
// TODO Auto-generated constructor stub
Log.i( LOG_TAG, "GCMIntentService constructor called" );
}
@Override
protected void onError( Context arg0, String errorId ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onError called: " + errorId );
}
@Override
protected void onMessage( Context arg0, Intent intent ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onMessage called" );
Log.i( LOG_TAG, "Message is: " + intent.getStringExtra( "message" ) );
}
@Override
protected void onRegistered( Context arg0, String registrationId ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onRegistered called" );
Log.i( LOG_TAG, "Registration id is: " + registrationId );
// ! ! ! CRASHES HERE ! ! !
}
@Override
protected void onUnregistered( Context arg0, String registrationId ) {
// TODO Auto-generated method stub
Log.i( LOG_TAG, "GCMIntentService onUnregistered called" );
Log.i( LOG_TAG, "Registration id is: " + registrationId );
}
}
这是 LogCat 的崩溃部分
