调用 GCMRegistrar.register() 时泄露的 IntentReceiver 错误

Question

我正在尝试从Google的Android开发人员站点完成Google的GCM入门步骤。

当我的设备尝试注册时，它失败，原因如下：

活动已经从最初在此处注册的com.google.android.gcm.GCMBroadcastReceiver泄露了IntentReceiver。您是否错过了取消注册接收器的呼叫？

这是代码：

GCMRegistrar.checkDevice(this);
GCMRegistrar.checkManifest(this);
final String regId = GCMRegistrar.getRegistrationId(this);
if (regId.equals("")) {
    GCMRegistrar.register(this, senderId); // <-- It fails here
} else {
    Log.v("GCM", "Already registered");
}

知道吗？

我做错了什么？

更新

这是我的清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.sample"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="8" />
    <permission android:name="com.sample.permission.C2D_MESSAGE" android:protectionLevel="signature" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
    <uses-permission android:name="com.sample.permission.C2D_MESSAGE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".sample"

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:theme="@android:style/Theme.NoTitleBar" android:name=".Main" android:screenOrientation="portrait" />
        <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.sample" />
          </intent-filter>
        </receiver>               
        <service android:name="com.sample.GCMIntentService" />
        <uses-library android:name="com.google.android.maps" />
    </application>
</manifest>

终于可以工作了。

我

需要做的就是在我调用的同一上下文中调用onDestroy()方法中的GCMRegistrar.onDestroy(this) GCMRegistrar.register()

在这里找到： Google Cloud Messaging 中泄露的 IntentReceiver

感谢您的支持:)

您应该使用应用程序上下文，而不是如下所示的活动上下文：

public String registerPushAccount()
{
    GCMRegistrar.checkDevice(getApplicationContext());
    GCMRegistrar.checkManifest(getApplicationContext());
    if (GCMRegistrar.isRegistered(getApplicationContext()))
    {
        Log.d("info", GCMRegistrar.getRegistrationId(getApplicationContext()));
    }
    String regId = GCMRegistrar.getRegistrationId(getApplicationContext());
    if (regId.equals(""))
    {
        regId = GCMRegistrar.getRegistrationId(getApplicationContext());
    }
    else
    {
        Log.d("info", "already registered as" + regId);
    }
    Log.d("info", regId);
    return regId;
}

这解决了我的问题:)

当我没有正确设置权限时，这发生在我身上。我通过在清单中添加来解决它：

<permission android:name="PACKAGE.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="PACKAGE.permission.C2D_MESSAGE" /> 
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

Answer 4

我已经让它处理了这个清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="PACKAGENAME"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />
    <permission android:name="PACKAGENAME.permission.C2D_MESSAGE" android:protectionLevel="signature" />
    <uses-permission android:name="PACKAGENAME.permission.C2D_MESSAGE" /> 
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
    <permission android:name="android.permission.WAKE_LOCK" android:protectionLevel="signatureOrSystem"/>
    <uses-permission android:name="android.permission.WAKE_LOCK"/>
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <service android:name="PACKAGENAME.GCMIntentService" />
        <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="PACKAGENAME" />
  </intent-filter>
</receiver> 
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

还要向从 GCMBaseIntentService 扩展的类添加一个空构造函数。在我的案例中命名为：GCMIntentService。
