Android SIP软电话，通话录音，VoIP电话，linphone电话

各位大佬好，我又来记笔记了~~

公司又提新需求了，需要开发一个能通话（呼叫客户的手机号码）自动录音的模块。刚接触这个是蒙的，经过一番研究，可实现通话录音的方式大致有下面几种：

方案一：点击拨号时，调用系统的拨号功能，同时应用内注册通话广播，检测通话状态，接通、挂断来决定开始录音和停止录音，录音可以使用MediaRecorder和AudioRecorder。

优缺点：实现方式简单，开发容易。但是缺点也有，受Android系统版本影响大，每次打开应用都需要进设置页面开启“无障碍”权限才能录音（目前Android8.0的不用），录音对方的声音较小。不过适当优化下也能用。

方案二：刷机，获取设备root权限，把应用修改为“系统”级别应用，就可以正常录制通话（跟手机自带的通话录音一样），具体怎么刷机自行百度

优缺点：参考手机自带的通话录音功能，效果还是非常好的，但是只能用于一些定制的设备。如正常的一些手机、pad用户就不得行了，因为客户不可能会去刷机来兼容我们的应用。

方案三： SIP软电话，集成第三方的VoIP网络电话，实现网络通话并录音，效果也还行。如linphone框架，也是本文要讲的。

优缺点：使用SIP软电话，前提是要有SIP服务器（网上有很多免费的SIP服务器），后面说具体的实现逻辑，通话录音还可以，双方声音都比较大。

方案四：呼叫时，点击开启系统的录音进行录制，返回我们应用时，把系统的录音文件拿出来展示或上传服务器，哈哈最笨的方案了，适配主流的机型（前提是手机支持通话录音，获取录音文件的路径各机型适配一下）。

优缺点：兼容性差，不推荐了。

本文主要记录的是《方案一》和《方案三》，下面 只介绍关键步骤，详见文末demo

方案一：

大致步骤: 1、权限申请

2、注册广播，开启服务进行录音

3、开始拨号

4、查看通话记录，播放录音文件

需要的权限，项目全部权限在这了，有的可能用不到。

<uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.FOREGROUND_SERVICE" /><uses-permission android:name="android.permission.CALL_PHONE" /><uses-permission android:name="android.permission.WRITE_CALL_LOG" /><uses-permission android:name="android.permission.READ_CALL_LOG" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permissionandroid:name="android.permission.MANAGE_EXTERNAL_STORAGE"tools:ignore="ScopedStorage" /><uses-permissionandroid:name="android.permission.MODIFY_PHONE_STATE"tools:ignore="ProtectedPermissions" /><uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /><uses-permissionandroid:name="android.permission.BIND_ACCESSIBILITY_SERVICE"tools:ignore="ProtectedPermissions" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

注册广播:

AndroidManifest文件添加 PhoneStateListener和MediaRecorderService

<receiverandroid:name=".callrecord.PhoneStateListener"android:enabled="true"android:exported="true"><intent-filter><action android:name="android.intent.action.PHONE_STATE" /></intent-filter>
</receiver><serviceandroid:name=".callrecord.MediaRecorderService"android:enabled="true"android:exported="true"android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE"><intent-filter><action android:name="android.accessibilityservice.AccessibilityService" /></intent-filter><meta-dataandroid:name="android.accessibilityservice"android:resource="@xml/accessibility_service_config" /></service>

PhoneStateListener类：

/*** @ClassName PhoneStateListener* @Description TODO* @Author HK.W   通话录音广播* @Date 2022/10/15 22:13*/
public class PhoneStateListener extends BroadcastReceiver {private static final String TAG = "通话状态监听";static boolean incoming_flag;private Context mContext;@Overridepublic void onReceive(Context ctx, Intent intent) {mContext = ctx;String event = intent.getStringExtra(TelephonyManager.EXTRA_STATE);Log.d(TAG, "通话状态：state:" + event);if (event.equals(TelephonyManager.EXTRA_STATE_RINGING)) {Log.d(TAG, "-->RINGING--正在响铃");incoming_flag = true;} else if (event.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {Log.d(TAG, "-->EXTRA_STATE_OFFHOOK--正在通话");startService(ctx, intent);} else if (event.equals(TelephonyManager.EXTRA_STATE_IDLE)) {Log.d(TAG, "-->EXTRA_STATE_IDLE--电话挂断--空闲");ctx.stopService(new Intent(ctx, MediaRecorderService.class));//AudioRecordUtil.getInstance().stopRecording();AudioRecorder.getInstance().stopRecord();}}private void startService(Context context, Intent intent) {Log.d(TAG, "-->startService--打开服务-检查权限");String[] PERMISSIONS = {Manifest.permission.RECORD_AUDIO,Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};if (hasPermissions(context, PERMISSIONS)) {Log.d(TAG, "-->startService--打开服务-权限已打开");intent.setClass(context, MediaRecorderService.class);intent.putExtra("incoming_flag", incoming_flag);if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {context.startForegroundService(intent);} else {context.startService(intent);}} else {Log.d(TAG, "-->startService--打开服务-权限未打开");}}public static boolean hasPermissions(Context context, String... permissions) {if (context != null && permissions != null) {for (String permission : permissions) {if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {return false;}}}return true;}
}

MediaRecorderService类：

public class MediaRecorderService extends AccessibilityService {private static final String TAG = "通话状态监听";NotificationManagerCompat notificationManager;private boolean incoming_flag;private String number;@Overridepublic void onInterrupt() {}@Overridepublic void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {}@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {if (intent != null) {Log.d(TAG, "-->startService--进入录音服务");number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);incoming_flag = intent.getBooleanExtra("incoming_flag", false);String phone = SpUtils.getInstance().getString(this, "phone", "Unknown");AudioRecorder.getInstance().createDefaultAudio(phone);AudioRecorder.getInstance().startRecord(new RecordStreamListener() {@Overridepublic void recordOfByte(byte[] data, int begin, int end) {Log.d(TAG, "data:" + data);}});notificationBuilder();}return START_STICKY;}private void notificationBuilder() {Log.d(TAG, "-->startService--录音服务--打开通知栏，让服务进入前台，避免被杀掉");if (Build.VERSION.SDK_INT >= 26) {String CHANNEL_ID = "my_channel_01";NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "Channel title",NotificationManager.IMPORTANCE_DEFAULT);((NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE)).createNotificationChannel(channel);Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID).setContentTitle("").setContentText("").build();startForeground(1, notification);} else {NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "CHANNEL_ID").setSmallIcon(R.mipmap.ic_launcher).setContentTitle("Recording").setPriority(NotificationCompat.PRIORITY_DEFAULT).setOngoing(true);notificationManager = NotificationManagerCompat.from(this);notificationManager.notify(1, builder.build());}}@Overridepublic void onDestroy() {super.onDestroy();Log.d(TAG, "-->startService--录音服务--服务被销毁---onDestroy()");stopRecording();}private void stopRecording() {Log.d(TAG, "-->startService--录音服务--停止录音");if (Build.VERSION.SDK_INT >= 26) {stopForeground(true);} else {NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);notificationManager.cancel(1);}}
}

功能相关页面截图：

拨号：

 private void callPhone(String phoneNumber) {Intent intentPhone = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneEt.getText().toString()));startActivity(intentPhone);}

开始录音

 @Overridepublic int onStartCommand(Intent intent, int flags, int startId) {if (intent != null) {Log.d(TAG, "-->startService--进入录音服务");number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);incoming_flag = intent.getBooleanExtra("incoming_flag", false);String phone = SpUtils.getInstance().getString(this, "phone", "Unknown");//开始录音AudioRecorder.getInstance().createDefaultAudio(phone);AudioRecorder.getInstance().startRecord(new RecordStreamListener() {@Overridepublic void recordOfByte(byte[] data, int begin, int end) {Log.d(TAG, "data:" + data);}});notificationBuilder();}return START_STICKY;}

停止录音：

public class PhoneStateListener extends BroadcastReceiver {private static final String TAG = "通话状态监听";static boolean incoming_flag;private Context mContext;@Overridepublic void onReceive(Context ctx, Intent intent) {mContext = ctx;String event = intent.getStringExtra(TelephonyManager.EXTRA_STATE);Log.d(TAG, "通话状态：state:" + event);if (event.equals(TelephonyManager.EXTRA_STATE_RINGING)) {Log.d(TAG, "-->RINGING--正在响铃");incoming_flag = true;} else if (event.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {Log.d(TAG, "-->EXTRA_STATE_OFFHOOK--正在通话");startService(ctx, intent);} else if (event.equals(TelephonyManager.EXTRA_STATE_IDLE)) {Log.d(TAG, "-->EXTRA_STATE_IDLE--电话挂断--空闲");ctx.stopService(new Intent(ctx, MediaRecorderService.class));//AudioRecordUtil.getInstance().stopRecording();//为什么不在服务里面停止录音？有的机型挂断电话后没有马上销毁服务，所以在状态这里直接停止录音AudioRecorder.getInstance().stopRecord();}}

本文demo 录音文件保存在根目录anyi.phone/record 文件下。

获取通话记录对应的录音文件:

 /*** 获取录音文件路径 --通话记录*/private List<RecordBean> getLocalRecord() {List<ContactsBean> contacts = readContacts();List<RecordBean> list = new ArrayList<>();JSONArray allFiles = getAllFiles("", "wav");//Log.d("allFiles", "allFiles:" + allFiles.toString());if (null != allFiles) {for (int i = 0; i < allFiles.length(); i++) {try {JSONObject jsonObject = allFiles.getJSONObject(i);String name = jsonObject.getString("name");String path = jsonObject.getString("path");String[] split1 = name.split("-");if (split1.length > 0) {RecordBean recordBean = new RecordBean();recordBean.setNumber(split1[0]);recordBean.setPath(path);recordBean.setDate(new SimpleDateFormat("HH:mm").format(new Date(Long.parseLong(split1[1]))));if (contacts.size() > 0) {for (ContactsBean b : contacts) {if (split1[0].equals(b.getNumber())) {recordBean.setCachedName(b.getName());}}} else {recordBean.setCachedName("未知");}list.add(recordBean);}} catch (JSONException e) {e.printStackTrace();}}Collections.reverse(list);return list;}return list;}public static JSONArray getAllFiles(String dirPath, String _type) {dirPath = "/storage/emulated/0/anyi.phone/record/";File f = new File(dirPath);if (!f.exists()) {//判断路径是否存在return null;}File[] files = f.listFiles();if (files == null) {//判断权限return null;}JSONArray fileList = new JSONArray();for (File _file : files) {//遍历目录if (_file.isFile() && (_file.getName().endsWith("amr")||_file.getName().endsWith("wav"))) {String _name = _file.getName();String filePath = _file.getAbsolutePath();//获取文件路径String fileName = _file.getName().substring(0, _name.length() - 4);//获取文件名try {JSONObject _fInfo = new JSONObject();_fInfo.put("name", fileName);_fInfo.put("path", filePath);fileList.put(_fInfo);} catch (Exception e) {}} else if (_file.isDirectory()) {//查询子目录//getAllFiles(_file.getAbsolutePath(), _type);} else {}}return fileList;}

播放：

 private void initPlay() {mediaPlayer = new MediaPlayer();}private void startPlay(String path) {if (TextUtils.isEmpty(path)) {Toast.makeText(this, "文件路径不存在", Toast.LENGTH_LONG).show();return;}mediaPlayer.reset(); //清空里面的其他歌曲try {mediaPlayer.setDataSource(path);mediaPlayer.prepare(); //准备就绪mediaPlayer.start(); //开始唱歌} catch (IOException e) {e.printStackTrace();}}

方案三，SIP通话录音，linphone 为例，只调试了音频通话，视频通话未调试

前提准备

准备一个SIP服务器地址和一个账号密码。可以自己搭建SIP服务器或者网上找一个SIP服务器注册一个账号密码。下面是网上找的资源，没试过。因为我们公司是购买的有SIP话机服务器的。

免费sip账号注册地址 http://serweb.iptel.org/user/reg/index.php
免费sip服务器   iptel.org
免费sip客户端 http://www.fring.com

正文：

1、把linphone-sdk-android-4.3.0-beta.aar包放在项目libs，提取码: nq6q。

2、配置文件注册服务：

 <serviceandroid:name=".linphone.LinphoneService"android:enabled="true"android:exported="true"android:label="@string/app_name" />

3.在启动页启动SIP相关服务,

启动页：

public class LauncherActivity extends AppCompatActivity {private static final String TAG = "XXPermissions";private Handler mHandler;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_launcher);mHandler = new Handler();}@Overrideprotected void onStart() {super.onStart();getPermission();}private void getPermission() {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {XXPermissions.with(this).permission(allPermission).request(new OnPermissionCallback() {@Overridepublic void onGranted(List<String> permissions, boolean all) {if (all) {if (LinphoneService.isReady()) {onServiceReady();} else {startService(new Intent().setClass(LauncherActivity.this, LinphoneService.class));new ServiceWaitThread().start();}}}@Overridepublic void onDenied(List<String> permissions, boolean never) {if (never) {Log.e(TAG, "onDenied：被永久拒绝授权，请手动授予权限 ");} else {Log.e(TAG, "onDenied: 权限获取失败");}}});} else {if (LinphoneService.isReady()) {onServiceReady();} else {startService(new Intent().setClass(LauncherActivity.this, LinphoneService.class));new ServiceWaitThread().start();}}}private void onServiceReady() {Intent intent = new Intent();intent.setClass(LauncherActivity.this, MainActivity.class);if (getIntent() != null && getIntent().getExtras() != null) {intent.putExtras(getIntent().getExtras());}intent.setAction(getIntent().getAction());intent.setType(getIntent().getType());startActivity(intent);}private class ServiceWaitThread extends Thread {public void run() {while (!LinphoneService.isReady()) {try {sleep(30);} catch (InterruptedException e) {throw new RuntimeException("waiting thread sleep() has been interrupted");}}mHandler.post(new Runnable() {@Overridepublic void run() {onServiceReady();}});}}
}

首页activity onResume（）方法中检测账号是否注册，未注册跳转到注册页面：

@Overrideprotected void onResume() {super.onResume();Log.d(TAG, "onResume()");LinphoneService.getCore().addListener(mCoreListener);ProxyConfig proxyConfig = LinphoneService.getCore().getDefaultProxyConfig();if (proxyConfig != null) {updateLed(proxyConfig.getState());} else {startActivity(new Intent(this, ConfigureAccountActivity.class));}}

/*** 注册*/private void configureAccount() {mAccountCreator.setUsername(mUsername.getText().toString());mAccountCreator.setDomain(mDomain.getText().toString());mAccountCreator.setPassword(mPassword.getText().toString());switch (mTransport.getCheckedRadioButtonId()) {case R.id.transport_udp:mAccountCreator.setTransport(TransportType.Udp);break;case R.id.transport_tcp:mAccountCreator.setTransport(TransportType.Tcp);break;case R.id.transport_tls:mAccountCreator.setTransport(TransportType.Tls);break;}ProxyConfig cfg = mAccountCreator.createProxyConfig();LinphoneService.getCore().setDefaultProxyConfig(cfg);}public void listener(){
mCoreListener = new CoreListenerStub() {/*** 监听注册是否成功* @param core* @param cfg* @param state* @param message*/@Overridepublic void onRegistrationStateChanged(Core core, ProxyConfig cfg, RegistrationState state, String message) {registerPr.setVisibility(View.GONE);if (state == RegistrationState.Ok) {finish();} else if (state == RegistrationState.Failed) {Toast.makeText(ConfigureAccountActivity.this, "Failure: " + message, Toast.LENGTH_LONG).show();}}};
}

注册成功开始通话：

 private void sipCallIng() {Core core = LinphoneService.getCore();Address addressToCall = core.interpretUrl(phoneEt.getText().toString());CallParams params = core.createCallParams(null);params.enableVideo(false);if (addressToCall != null) {String filePath = AudioRecordUtil.getInstance().getFilename(phoneEt.getText().toString(), ".wav");android.util.Log.d("linPhone--", "开始呼叫--号码--filePath = " + filePath);//重要：通话前需要设置录音文件，要不不会录音，params.setRecordFile(filePath);core.inviteAddressWithParams(addressToCall, params);Intent intent = new Intent(getActivity(), CallActivity.class);intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);startActivity(intent);}}

开始录音：

/*** ---通话接通--开始录音*/private void startRecord() {android.util.Log.d("linPhone--", "接通或者拒绝");android.util.Log.d("linPhone--", "开始录音：录音地址：" + core.getRecordFile());call.startRecording();}

停止录音：

 /*** ---通话挂断--停止录音--销毁页面*/private void stopRecord() {android.util.Log.d("linPhone--", "挂断，未接");android.util.Log.d("linPhone--", "停止录音");call.stopRecording();//停止录音finish();//挂断电话-销毁页面}

后面就是拿到录音文件播放，-----具体就不说了，

研究SIP也用了大量时间和下载了很多大佬的资源，也花费了很多积分，

so 想要demo的朋友们也希望支持一下，

demo需要积分下载，具体多少由平台分配。

本文demo成功实现了两种主流的通话录音方式，应该是能满足你们的业务需求的，
