[英]Unable to receive SIP calls when app is killed
即使应用程序处于后台,退出或重新启动,我该怎么做才能接收SIP呼叫? 目前我们正在运行带有粘性通知的前台服务,以便与我们的SIP服务器保持连接。 这个解决方案还没有完全正常工作请帮我实现这个,提前谢谢!
首先,您需要一个永不停止的Mainservice(即使设备在启动接收器的帮助下启动)。 您必须初始化您的sip管理器,sip配置文件并在MainService中调用相关代码,而不是在MainActivity中。
然后,您需要一个接收传入SIP呼叫的BroadCast接收器。 见下面的例子,
公共类YourReceiver扩展BroadcastReceiver {
SipAudioCall incomingCall = null;
private static YourReceiver instance;
MainService mainService;
public Intent incomingCallIntent;
public static YourReceiver getInstance() {
return instance;
}
/**
* Processes the incoming call, answers it, and hands it over to the
* MainActivity.
* @param context The context under which the receiver is running.
* @param intent The intent being received.
*/
@Override
public void onReceive(final Context context, Intent intent) {
Log.i(TAG, "onReceive: ");
instance = this;
mainService = MainService.getInstance();
try {
SipAudioCall.Listener listener = new SipAudioCall.Listener() {
@Override
public void onRinging(SipAudioCall call, SipProfile caller) {
Log.i(TAG, "onRinging: ");
}
// extra added
@Override
public void onRingingBack(SipAudioCall call) {
Log.i(TAG, "onRingingBack: ");
super.onRingingBack(call);
}
@Override
public void onReadyToCall(SipAudioCall call) {
Log.i(TAG, "onReadyToCall: ");
super.onReadyToCall(call);
}
@Override
public void onError(SipAudioCall call, int errorCode, String errorMessage) {
Log.e(TAG, "onError: errorCode = " + errorCode + ", errorMessage = " + errorMessage);
super.onError(call, errorCode, errorMessage);
}
@Override
public void onChanged(SipAudioCall call) {
Log.i(TAG, "onChanged: ");
super.onChanged(call);
}
@Override
public void onCalling(SipAudioCall call) {
Log.i(TAG, "onCalling: ");
super.onCalling(call);
}
@Override
public void onCallHeld(SipAudioCall call) {
Log.i(TAG, "onCallHeld: ");
super.onCallHeld(call);
}
@Override
public void onCallBusy(SipAudioCall call) {
Log.i(TAG, "onCallBusy: ");
super.onCallBusy(call);
}
@Override
public void onCallEnded(SipAudioCall call) {
Log.i(TAG, "onCallEnded: ");
}
@Override
public void onCallEstablished(SipAudioCall call) {
Log.i(TAG, "onCallEstablished: ");
super.onCallEstablished(call);
}
};
mainService = MainService.getInstance();
incomingCall = mainService.manager.takeAudioCall(intent,listener);
if(mainService.manager.isIncomingCallIntent(intent)){
incomingCallIntent = intent;
}
//starting call screen activity when the receiver receives incoming call
Intent i = new Intent(context, CallActivity.class);
i.putExtra("name", peerName);
i.putExtra("number", peerNumber);
i.putExtra("callType", "Incoming");
context.startActivity(i);
//将YourReceiver收到的SIP调用分配给MainService.call,以便MainService可以执行进一步的处理。
mainService.call = incomingCall;
} catch (Exception e) {
if (incomingCall != null) {
incomingCall.close();
}
}
}
}
运行服务是正确的方法。 您只需启动将处理来自服务的来电的活动。 然后,活动可以绑定到您的服务并请求接管呼叫所需的全部内容。 这实际上就是你所需要的一切。
要使服务连续运行,请启动Job scheduler以使此作业成为android系统作业的一部分。
package com.xxx;
import android.app.job.JobParameters;
import android.app.job.JobService;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.util.Log;
import androidx.annotation.RequiresApi;
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
public class XXJobService extends JobService {
private String TAG = "XXJobService";
private Context context;
public XXJobService() {
}
@Override
public boolean onStartJob(JobParameters params) {
context = this;
try {
if (!MyApp.isServiceRunning(context, MainService.class.getName())) {
Log.i(TAG, "onStartJob : MainService not running so start");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
context.getApplicationContext()
.startForegroundService(new Intent(context, MainService.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
} else {
context.getApplicationContext()
.startService(new Intent(context, MainService.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
}
}
} catch (Exception e) {
Log.e(TAG, "Exception - MainService not running: " + e.getLocalizedMessage());
}
Log.i(TAG, "onStartJob, returnValue = " + returnValue);
return returnValue;
}
@Override
public boolean onStopJob(JobParameters params) {
boolean returnValue = true;
Log.i(TAG, "onStopJob, returnValue = " + returnValue);
return returnValue;
}
}
在项目中创建一个扩展Application的Application类,并在清单中定义它。
import android.app.ActivityManager;
import android.app.Application;
import android.app.job.JobInfo;
import android.app.job.JobScheduler;
import android.content.ComponentName;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Build;
import android.util.Log;
import java.util.Arrays;
import java.util.List;
public class MyApp extends Application {
Context context;
private static MyApp instance;
static String TAG = "MyApp";
MainService mainService;
JobScheduler jobScheduler;
private static final int JOB_ID = 1;
public static MyApp getInstance() {
return instance;
}
@Override
public void onCreate() {
super.onCreate();
context = this;
instance = this;
Log.i(TAG, "onCreate: ");
// Job scheduler for android version Lolipop(Android 5.0) and above
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
try {
jobScheduler = (JobScheduler) getSystemService(JOB_SCHEDULER_SERVICE);
ComponentName jobService = new ComponentName(getPackageName(), XXJobService.class.getName());
Log.e(TAG, "onCreate: ComponentName : " + jobService );
JobInfo jobInfo = new JobInfo.Builder(JOB_ID, jobService)
.setPersisted(true)
.setPeriodic(5000)
.build();
int jobId = jobScheduler.schedule(jobInfo);
if (jobId == JobScheduler.RESULT_SUCCESS) {
Log.e(TAG, "JobScheduler RESULT_SUCCESS");
// Toast.makeText(context, "Successfully scheduled job : " + jobId, Toast.LENGTH_SHORT).show();
} else {
Log.e(TAG, "JobScheduler RESULT_FAILURE: " + jobId);
// Toast.makeText(context, "RESULT_FAILURE: " + jobId, Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
Log.e(TAG, "JobScheduler Exception : " + e.getLocalizedMessage());
}
}
if (!isServiceRunning(context, MainService.class.getName())) {
try {
Intent intent = new Intent(context, MainService.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
startForegroundService(intent);
} else {
startService(intent);
}
} catch (Exception e) {
Log.e(TAG, "Exception startService : " + e.getLocalizedMessage());
}
}
mainService = MainService.getInstance();
Log.e(TAG," MainSerivice : " + mainService);
Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
@Override
public void uncaughtException(Thread t, Throwable e) {
handleUncaughtException(t, e);
}
});
}
public static boolean isServiceRunning(Context context, String serviceClassName) {
if (context == null || serviceClassName.equalsIgnoreCase("")) {
Log.i(TAG, "isServiceRunning called with context = null or service name blank");
return false;
}
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);
for (ActivityManager.RunningServiceInfo runningServiceInfo : services) {
if (runningServiceInfo.service.getClassName().equals(serviceClassName))
return true;
}
return false;
}
}
最后,将BootUpReceiver置于手机重启时自动启动通知和服务。 它应该有权限
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<receiver
android:name=".StartupReceiver"
android:enabled="true">
<intent-filter>
<action android:name="com.xx.MainService" />
<action android:name="android.intent.action.ACTION_SHUTDOWN" />
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
