android-C2DM inapp注册：无法启动服务意图

好吧,我真的不知道我在这里缺少什么.我试图让C2DM能够为我们的应用程序工作,尤其是处理广播使我感到挣扎.

我们有一个适用于整个应用程序的BroadcastReceiver：

public final class AppBroadcastReceiver extends BroadcastReceiver {

    //get an instance if not already present
    public static AppBroadcastReceiver getInstance(final IntentFilter filter) {
        if (instance == null) {
            instance = new GlobalBroadcastReceiver();
        }
        if (filter != null) {
            filter.addAction("com.google.android.c2dm.intent.REGISTRATION";
            filter.addAction("com.google.android.c2dm.intent.RECEIVE");
            filter.addCategory("my.package.name");
        }
        return instance;
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        final String broadcastAction = intent.getAction();
        Log.d(logTag, String.format("GlobalBroadcastReceiver::onReceive for action = %s", broadcastAction));

        if ("com.google.android.c2dm.intent.REGISTRATION".equals(broadcastAction)) {
            for (final AppBroadcastListener l : listeners) {
                l.c2dmRegistration(intent);
            }
        } else if ("com.google.android.c2dm.intent.RECEIVE".equals(broadcastAction)) {
            for (final ApplBroadcastListener l : listeners) {
                l.c2dmReceive(intent);
            }
        }//else
    }//onReceive
}

AppBroadcastListener是我们所有活动都正在实现的接口,以确保至少存在适当的方法.在它们的onResume()中,onStop()方法分别在接收方注册和注销活动.

出于测试目的,我有一个Debug Activity证明了以下两种方法：

public void sendC2DM(View v){
    Intent intent= new Intent();
    intent.setAction(com.google.android.c2dm.intent.RECEIVE);
    intent.putExtra("message","Bender: \"kiss my shiny metal ass!\"");
    intent.addCategory(getPackageName() );

    sendBroadcast(intent);
}

public void registerC2DM(View v){
    Intent registrationIntent = new Intent(com.google.android.c2dm.intent.REGISTRATION);
    registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); // boilerplate
    registrationIntent.putExtra("sender", ourSenderIdregistered@googlemail.com);
    startService(registrationIntent);
}

在android.manifest中,我在< application>-标签中添加了以下行：

    <receiver
        android:name=".AppBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >

        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />

            <category android:name="my.package.name" />
        </intent-filter>
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="my.package.name" />
        </intent-filter>
    </receiver>

因此,我们希望接收广播的每个活动都在onResume()上的BroadcastReceiver上注册自己,当发生某些事情时,BroadcastReceiver会捕获并调用已实现的方法.例如. ,记录消息或显示Toast.

但是,当我发送“ C2DM消息”时,我看到此结构适用于自制广播. (Bender的消息在Toast中弹出),但是registerC2DM().startService(registrationIntent);只是记录：

Unable to start service Intent {
act=com.google.android.c2dm.intent.REGISTRATION (has extras) }: not
found

我不知道我在这里想念什么.一般建议似乎是：检查您的android.manifest(已完成)或：使用注册的gmail帐户登录.
不知道这个.是的,我用gmail帐户登录,但没有使用ourSenderIdregistered@googlemail.com登录,我们在注册时将其放入了意图.我也坚信这不是解决方案. (告诉我们所有的客户使用该帐户登录…嗯,不是吗？！).
所以我想那是另外一回事,但我只是找不到：C

解决方法:

好的,这真的是要发现：

如果要注册c2dm,请使用

com.google.android.c2dm.intent.REGISTER

但是要获取此消息的答案,您必须先设置广播接收器才能收听

com.google.android.c2dm.intent.REGISTRATION

微妙？是的,这里再次是错误和更正的版本：

//false
public void registerC2DM(View v){
    Intent registrationIntent = new Intent(com.google.android.c2dm.intent.REGISTRATION);
    registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); // boilerplate
    registrationIntent.putExtra("sender", ourSenderIdregistered@googlemail.com);
    startService(registrationIntent);
}


//true
public void registerC2DM(View v){
    Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0)); // boilerplate
registrationIntent.putExtra("sender", ourSenderIdregistered@googlemail.com);
    startService(registrationIntent);
}

在意识到这一点之前砸碎了3个键盘…
