android - GCMBaseIntentService 回调仅在根包中

Question

我在我的应用程序中实现了 GCM，但遇到了一个奇怪的问题。当我为 GCMBaseIntentService 覆盖的 IntentService 位于我的根包中时，它工作正常。我在 list 中使用 .MyGCMIntentService 引用它。根包将是 com.example.rootpackage

当我将我的 Intent 服务移动到不同的包时，例如 com.example.rootpackage.service Intent 服务永远不会被调用。此时我会更新我的 list 以指向 com.example.rootpackage.service.MyGCMIntentService 并且没有骰子。

我是否遗漏了 Google 文档中有关定位它的内容，或者这就是它的工作原理？

Answer 1

是的，它应该在根包中:

This intent service will be called by the GCMBroadcastReceiver (which is provided by the GCM library), as shown in the next step. It must be a subclass of com.google.android.gcm.GCMBaseIntentService, must contain a public constructor, and should be named my_app_package.GCMIntentService (unless you use a subclass of GCMBroadcastReceiver that overrides the method used to name the service).

编辑:

如文档所述，如果您使用覆盖 getDefaultIntentServiceClassName 的 GCMBroadcastReceiver 的子类，则可以更改它:

public class GCMBroadcastReceiver extends BroadcastReceiver {

    private static final String TAG = "GCMBroadcastReceiver";
    private static boolean mReceiverSet = false;

    @Override
    public final void onReceive(Context context, Intent intent) {
        Log.v(TAG, "onReceive: " + intent.getAction());
        // do a one-time check if app is using a custom GCMBroadcastReceiver
        if (!mReceiverSet) {
            mReceiverSet = true;
            String myClass = getClass().getName();
            if (!myClass.equals(GCMBroadcastReceiver.class.getName())) {
                GCMRegistrar.setRetryReceiverClassName(myClass);
            }
        }
        String className = getGCMIntentServiceClassName(context);
        Log.v(TAG, "GCM IntentService class: " + className);
        // Delegates to the application-specific intent service.
        GCMBaseIntentService.runIntentInService(context, intent, className);
        setResult(Activity.RESULT_OK, null /* data */, null /* extra */);
    }

    /**
     * Gets the class name of the intent service that will handle GCM messages.
     */
    protected String getGCMIntentServiceClassName(Context context) {
        return getDefaultIntentServiceClassName(context);
    }

    /**
     * Gets the default class name of the intent service that will handle GCM
     * messages.
     */
    static final String getDefaultIntentServiceClassName(Context context) {
        String className = context.getPackageName() +
                DEFAULT_INTENT_SERVICE_CLASS_NAME;
        return className;
    }
}
