您所面臨的問題，因爲你的服務沒有與onListener實現爲您使用的「本」就意味着你是闖民宅落實到同一類初始化，但我得到了你在找什麼：
你要動態服務和其他一些類 實現讀心人之間具有約束力，但我要提出一個漫長的辦法做到這一點 因爲
FirebaseInstanceIdService
是服務和使用由服務接口不建議，您可以通過發送廣播，如果您的應用程序沒有運行需要從服務更新，如果你的應用程序正在運行，然後使用IPC做到這一點，並從信使送令牌
在你的活動或片段使用下面 第1步的代碼：建立呼入處理程序
class IncomingHandler extends Handler {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case MessengerService.MSG_SET_VALUE:
mCallbackText.setText("Received from service: " + msg.obj);
break;
default:
super.handleMessage(msg);
}
}
}
/**
* Target we publish for clients to send messages to IncomingHandler.
*/
final Messenger mMessenger = new Messenger(new IncomingHandler());
2：創建服務連接：
/**
* Class for interacting with the main interface of the service.
*/
private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className,
IBinder service) {
// This is called when the connection with the service has been
// established, giving us the service object we can use to
// interact with the service. We are communicating with our
// service through an IDL interface, so get a client-side
// representation of that from the raw service object.
mService = new Messenger(service);
mCallbackText.setText("Attached.");
// We want to monitor the service for as long as we are
// connected to it.
try {
Message msg = Message.obtain(null,
MessengerService.MSG_REGISTER_CLIENT);
msg.replyTo = mMessenger;
mService.send(msg);
// Give it some value as an example.
msg = Message.obtain(null,
MessengerService.MSG_SET_VALUE, this.hashCode(), 0);
mService.send(msg);
} catch (RemoteException e) {
// In this case the service has crashed before we could even
// do anything with it; we can count on soon being
// disconnected (and then reconnected if it can be restarted)
// so there is no need to do anything here.
}
}
public void onServiceDisconnected(ComponentName className) {
// This is called when the connection with the service has been
// unexpectedly disconnected -- that is, its process crashed.
mService = null;
}
};
3：調用綁定befor Ë呼籲得到令牌
void doBindService() {
// Establish a connection with the service. We use an explicit
// class name because there is no reason to be able to let other
// applications replace our component.
bindService(new Intent(MessengerServiceActivities.this,
MessengerService.class), mConnection, Context.BIND_AUTO_CREATE);
mIsBound = true;
}
FirebaseInstanceId.getInstance().getToken();
4：最後在你的FirebaseInstanceIdService類
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String TAG = "MyFirebaseIIDService";
/**
* Keeps track of all current registered clients.
*/
ArrayList<Messenger> mClients = new ArrayList<Messenger>();
/**
* Holds last value set by a client.
*/
/**
* Command to the service to register a client, receiving callbacks
* from the service. The Message's replyTo field must be a Messenger of
* the client where callbacks should be sent.
*/
public static final int MSG_REGISTER_CLIENT = 1;
/**
* Command to the service to unregister a client, ot stop receiving callbacks
* from the service. The Message's replyTo field must be a Messenger of
* the client as previously given with MSG_REGISTER_CLIENT.
*/
public static final int MSG_UNREGISTER_CLIENT = 2;
/**
* Command to service to set a new value. This can be sent to the
* service to supply a new value, and will be sent by the service to
* any registered clients with the new value.
*/
public static final int TOKEN_REFRESHED = 3;
class IncomingHandler extends Handler {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case MSG_REGISTER_CLIENT:
mClients.add(msg.replyTo);
break;
case MSG_UNREGISTER_CLIENT:
mClients.remove(msg.replyTo);
break;
case TOKEN_REFRESHED:
for (int i = mClients.size() - 1; i >= 0; i--) {
try {
mClients.get(i).send(Message.obtain(null,
TOKEN_REFRESHED, msg.arg1, 0));
} catch (RemoteException e) {
// The client is dead. Remove it from the list;
// we are going through the list from back to front
// so this is safe to do inside the loop.
mClients.remove(i);
}
}
break;
default:
super.handleMessage(msg);
}
}
}
/**
* Called if InstanceID token is updated. This may occur if the security of
* the previous token had been compromised. Note that this is called when the InstanceID token
* is initially generated so this is where you would retrieve the token.
*/
// [START refresh_token]
@Override
public void onTokenRefresh() {
// Get updated InstanceID token.
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
Message msg = Message.obtain(null,
TOKEN_REFRESHED);
msg.obj = refreshedToken;
// TODO: Implement this method to send any registration to your app's servers.
sendRegistrationToServer(refreshedToken);
}
// [END refresh_token]
/**
* Persist token to third-party servers.
* <p/>
* Modify this method to associate the user's FCM InstanceID token with any server-side account
* maintained by your application.
*
* @param token The new token.
*/
private void sendRegistrationToServer(String token) {
// Add custom implementation, as needed.
Log.e("", "FCM Token: " + token);
}
}
