无法实例化GcmBroadcastReceiver

问题描述

我试图根据Google手册

但是，当我收到消息 - 我有这个错误：

我在寻找所有相同的问题，但他们没有解决方案或解决方案没有帮助，或者他们已被弃用。

我的清单：

 <？xml version =1 .0encoding =utf-8？> 
< manifest xmlns：android =http://schemas.android.com/apk/res/android
 package =com.example.testpushnotification
 android：versionCode = 1
 android：versionName =1.0>

< application 
 
 android：allowBackup =true

 android：theme =@ style / AppTheme> 
< meta-data android：name =com.google.android.gms.version
 android：value =@ integer / google_play_services_version/> 
 
< activity 
 android：name =com.example.testpushnotification.MainActivity
 android：label =@ string / app_name> 
< intent-filter> 
  
< category android：name =android.intent.category.LAUNCHER/> 
< / intent-filter> 
< / activity> 
< receiver 
 android：name =.GcmBroadcastReceiver
 android：permission =com.google.android.c2dm.permission.SEND> 
< intent-filter> 
  < category android：name =com.example.testpushnotification/> 
< / intent-filter> 
< / receiver> 
< service android：name =.GcmIntentService/> 
< / application> 
  

以及GcmBroadcastReceiver的源代码com.example.testpushnotification包：

  public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
 @Override 
 public void onReceive（Context context，Intent intent）{
 //明确指定GcmIntentService将处理意图。 
 ComponentName comp = new ComponentName（context.getPackageName（），
 GcmIntentService.class.getName（））; 
 //启动服务，保持设备在启动时保持清醒状态。 
 startWakefulService（context，（intent.setComponent（comp）））; 
 setResultCode（Activity.RESULT_OK）; 
} 
  

为什么Dex路径包含与我不同的包？

请问，如何解决它？

FIXED 更改< receiver
android：name =.GcmBroadcastReceiver
..
< / receiver>

code>< receiver
android：name =com.google.android.gcm.GCMBroadcastReceiver
..
< / receiver> （例如：

解决方案

试试这个：

Properties / Java Build Path / Order and Export - 确保在Android Dependencies和支持库前面有一个检查，如果你使用它的话。标记所有的复选框。点击Apply并清理项目。

添加如下：

 < receiver 
 android：name =com。 google.android.gcm.GCMBroadcastReceiver
 android：permission =com.googl e.android.c2dm.permission.SEND> 
< intent-filter> 
   
< category android：name =com.test.android/> 
< / intent-filter> 
< / receiver> 
  

它应该是： com.google.android.gcm.GCMBroadcastReceiver 和不是 .GCMBroadcastReceiver

这对我有效。希望这有助于您。

I tried to create test app with GCM service, according to the Google manual https://developer.android.com/google/gcm/client.html#app

But when i receive message - I have this error:

I was looking for all same questions, but they have no solutions or solutions didn't help or they are deprecated.

My manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.testpushnotification"
   android:versionCode="1"
   android:versionName="1.0" >

            android:protectionLevel="signature"/>

<application

    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <meta-data android:name="com.google.android.gms.version"
           android:value="@integer/google_play_services_version"/>

    <activity
        android:name="com.example.testpushnotification.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
            <category android:name="com.example.testpushnotification"/>
        </intent-filter>
    </receiver>
    <service android:name=".GcmIntentService"/>
</application>

And source code for GcmBroadcastReceiver in the com.example.testpushnotification package:

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Explicitly specify that GcmIntentService will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                GcmIntentService.class.getName());
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }

And why Dex path contains differ package than my?

Please, how to fix it ?

FIXED Changed <receiver android:name=".GcmBroadcastReceiver" .. </receiver>

to <receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" .. </receiver> (case sensetive)

解决方案

Try this:

Go to Project/Properties/Java Build Path/Order and Export -- Make sure there's a check in front of Android Dependencies and the support library, if you use it.Mark all checkboxes.Click on Apply and clean the project.

Add like this :

   <receiver
        android:name="com.google.android.gcm.GCMBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="com.test.android" />
        </intent-filter>
    </receiver>

It should be : com.google.android.gcm.GCMBroadcastReceiver and not .GCMBroadcastReceiver

This worked for me.Hope this helps.
