我正在按照此文档来实施我的Google Cloud Messaging客户端应用程序:http://developer.android.com/google/gcm/client.html除了“发送消息”步骤之外,我已经完成了所有步骤,因为我不需要“向服务器发送上游消息”功能
但是,我可以从GCM服务器获取“注册ID”并成功将其传递给我的服务器,但我无法在客户端应用程序中从我的服务器接收推送通知。 服务器端代码由另一个开发人员检查,一切似乎都没问题。问题出在我的客户端应用程序中。
也许我的广播接收器没有被触发,因为我没有在Google文档中实现“发送消息”部分?那部分:
public void onClick(final View view) {
if (view == findViewById(R.id.send)) {
new AsyncTask() {
@Override
protected String doInBackground(Void... params) {
String msg = "";
try {
Bundle data = new Bundle();
data.putString("my_message", "Hello World");
data.putString("my_action",
"com.google.android.gcm.demo.app.ECHO_NOW");
String id = Integer.toString(msgId.incrementAndGet());
gcm.send(SENDER_ID + "@gcm.googleapis.com", id, data);
msg = "Sent message";
} catch (IOException ex) {
msg = "Error :" + ex.getMessage();
}
return msg;
}
@Override
protected void onPostExecute(String msg) {
mDisplay.append(msg + "\n");
}
}.execute(null, null, null);
} else if (view == findViewById(R.id.clear)) {
mDisplay.setText("");
}
}
来自Google文档的报价:“广播接收器是GCM用于传递消息的机制。当onClick()调用gcm.send()时,它会触发广播接收器的onReceive()方法,该方法负责确保处理GCM消息。“因为我没有实现onClick()方法,所以我也没有实现gcm.send()方法。
如何触发广播接收器,它能够在我的情况下接收传入的推送通知?
