Question

使用广播时遇到此问题。使用BroadcastReceiver时会发生错误。

以下是代码：

<receiver
        android:name="com.org.ti.lucky.gcm.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>

            <!-- Receives the actual messages. -->
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />

            <category android:name="com.org.ti.lucky.gcm" />
        </intent-filter>
    </receiver>

    <service android:name="com.org.ti.lucky.gcm.GcmIntentService" />

这是类和错误：

package com.org.ti.lucky.gcm;

import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.support.v4.content.WakefulBroadcastReceiver;


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);
    }
}

这是logcat输出：
