Question

我正在尝试在我的应用中设置GCM（只是搞清楚GCM服务）。

到目前为止，我有一个基本的应用程序，它所要做的就是注册并注销GCM。

我一直在关注：

我遇到了一个关于Android L的问题。

我看过Google In-App billing, IllegalArgumentException: Service Intent must be explicit, after upgrading to Android L Dev Preview，但老实说我不明白给出的答案？

我的代码如下：

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    deactivate = (Button) findViewById(R.id.deactivate);
    activate = (Button) findViewById(R.id.activate);
    activate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            register(v);
        }
    });

    deactivate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            deregister(v);
        }
    });

}

private void deregister(View v) {
    Intent deregister = new Intent("com.google.android.c2dm.intent.UNREGISTER");
    deregister.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
    startService(deregister);
}

public void register(View view) {
    Intent register = new Intent("com.google.android.c2dm.intent.REGISTER");
    register.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
    register.putExtra("sender", "XXXXXXXXX");
    startService(register);

}

Answer 1

您需要在意图中指定要注册/取消注册的类。尝试添加register.setClass(this, MyClassToUse.class);和unregister.setClass(this, MyClassToUse.class);

服务意图必须明确配置google cloud messenger
