<receiver>
我可以使用清单中的 a 成功向 C2DM 注册我的 android 应用程序。但是,如果我从清单中删除<receiver>
并使用上下文的方法 registerReceiver 注册我的接收器,我会收到SERVICE_NOT_AVAILABLE
错误响应。我已经在模拟器和真实设备中重现了这种行为。
可以动态注册 C2DM 接收器吗?
这是我删除的清单片段:
<receiver android:name=".service.C2DM.C2DMReceiver" android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<category android:name="mytestapp" />
</intent-filter>
<intent-filter>
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="mytestapp" />
</intent-filter>
</receiver>
这是代码:
public class C2DMReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String registration = intent.getStringExtra("registration_id");
if (intent.getStringExtra("error") != null) {
//TODO: Registration failed, should try again later.
Log.e("MyTestAppC2DM", "C2DM Error = " + intent.getStringExtra("error"));
} else if (intent.getStringExtra("unregistered") != null) {
Log.d("MyTestAppC2DM", "C2DM Unregistered");
} else if (registration != null) {
Log.d("MyTestAppC2DM","C2DM registration_id = " + registration);
} else {
Log.w("MyTestAppC2DM", "C2DM No registration_id");
}
}
public static void register(Context context){
/* BEGIN OF DYNAMIC REGISTER */
C2DMReceiver c2dmReceiver = new C2DMReceiver();
IntentFilter receiveIntentFilter = new IntentFilter();
receiveIntentFilter.addAction("com.google.android.c2dm.intent.RECEIVE");
receiveIntentFilter.addCategory("mytestapp");
context.registerReceiver(c2dmReceiver, receiveIntentFilter, "com.google.android.c2dm.permission.SEND", null);
IntentFilter registrationIntentFilter = new IntentFilter();
registrationIntentFilter.addAction("com.google.android.c2dm.intent.REGISTRATION");
registrationIntentFilter.addCategory("mytestapp");
context.registerReceiver(c2dmReceiver, registrationIntentFilter, "com.google.android.c2dm.permission.SEND", null);
/*END OF DYNAMIC REGISTER*/
Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
registrationIntent.putExtra("app", PendingIntent.getBroadcast(context, 0, new Intent(), 0));
registrationIntent.putExtra("sender", "mysender@gmail.com");
ComponentName service = context.startService(registrationIntent);
if(service!=null){
Log.d("MyTestAppC2DM","C2DM Registration sent");
}else{
Log.d("MyTestAppC2DM","C2DM Service not found");
}
}
}
