无论应用程序当前是否正在运行，我都需要能够接收传入的 Twilio 调用。
一旦用户启动应用程序并登录到我们的服务器，我将启动如下所示的服务。
该服务是粘性启动的，并且从未调用过stopService 或stopSelf 等，因此该服务在应用程序关闭后仍应运行。
当应用程序运行时，
IncomingCallActivity正常启动以响应 Twilio 调用。如果应用程序在后台，
IncomingCallActivity仍然可以正常启动以响应 Twilio 调用。如果应用程序关闭，
IncomingCallActivity将不再启动以响应 Twilio 调用。
为什么应用已经关闭，IncomingCallActivity 没有启动？？
public class CallService extends Service implements Twilio.InitListener, DeviceListener, ConnectionListener {
private Device mDevice;
private Connection mConnection;
@Override
public void onCreate() {
super.onCreate();
registerBroadcastReceiver();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// Initialize the Twilio SDK if required
if (!Twilio.isInitialized()) {
Twilio.initialize(getApplicationContext(), this);
} else {
getCapabilityToken("CallService", getUser());
}
...
return START_STICKY;
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onDestroy() {
// Unregister broadcast receiver
final LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);
localBroadcastManager.unregisterReceiver(mBroadcastReceiver);
super.onDestroy();
}
@Override
public void onInitialized() {
getCapabilityToken("CallService", getUser());
}
@Override
public void onError(Exception e) {
}
private void getCapabilityToken(String string, User user) {
// Request the capability token from the server.
...
}
protected void setCapabilityToken() {
// Create device using the capability token
mDevice = Twilio.createDevice(getUser().capabilityToken, this);
// Set pending intent for Twilio device
Intent intent = new Intent(this, IncomingCallActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
mDevice.setIncomingIntent(pendingIntent);
// Broadcast that CallService is ready, to any registered receivers
Intent broadcastIntent = new Intent(App.ACTION__TWILIO_SERVICE_READY);
LocalBroadcastManager.getInstance(this).sendBroadcast(broadcastIntent);
}
public void connect() {
mConnection = mDevice.connect(null /* parameters */, null /* ConnectionListener */);
if (mConnection == null) {
...
} else {
...
}
}
private void answerCall(Device device, Connection connection) {
if (mConnection != null) {
mConnection.disconnect();
}
mConnection = connection;
mConnection.accept();
}
/**
* BroadcastReceiver
*/
private BroadcastReceiver mBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
switch (action) {
case App.ACTION__CAPABILITY_TOKEN_OBTAINED:
setCapabilityToken();
break;
case App.ACTION__CONNECT:
connect();
break;
}
}
};
@Override
public void onStartListening(Device device) {
}
@Override
public void onStopListening(Device device) {
}
@Override
public void onStopListening(Device device, int i, String s) {
}
@Override
public boolean receivePresenceEvents(Device device) {
return false;
}
@Override
public void onPresenceChanged(Device device, PresenceEvent presenceEvent) {
}
@Override
public void onConnecting(Connection connection) {
}
@Override
public void onConnected(Connection connection) {
}
@Override
public void onDisconnected(Connection connection) {
}
@Override
public void onDisconnected(Connection connection, int i, String s) {
}
}
编辑:
为了阐明我是如何声明我的服务等的，这是我的 AndroidManifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest package="au.com.encall.encall"
xmlns:android="http://schemas.android.com/apk/res/android">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<meta-data

...
</application>
</manifest>
最佳答案
如果您使用的是 twilio 演示，那么您需要在 Androidmenifest 中提供服务
<service android:name="com.twilio.client.TwilioClientService" android:exported="false" android:stopWithTask="true"/>
它对我有用。
twilio provide他们自己的服务。所以你只需要在 menifest 上声明它。所以不需要创建新服务。
jusr 删除此服务并将其放在 android menifest 上。它会在应用程序关闭后自动启动。
关于android - 如果应用关闭，粘性服务中定义的 Twilio 设备不会启动 Activity ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35595666/
