本文实例为大家分享了Android实现类似微信视频接听的具体代码，供大家参考，具体内容如下

1、背景需求：业务需要接入视频审核功能，在PC 端发起视频通话，移动端显示通话界面点击接听后进行1对1视频通话。

2、解决方案：因为项目没有IM功能。只集成了极光消息推送(极光消息推送接入参考官方文档，经过跟需求沟通，采用消息推送调起通话接听界面。再集成腾讯实时音视频SDK（具体集成方式参考官方文档）。最终实现类似微信1对1通话功能。

3、技术实现：

A:编写一个广播接收器，并且在 AndroidManifest中注册，这就是一个全局的广播接收器。应用退到后台或者应用进程被kill，只要极光的push进程是Live，就能接受到消息，启动通话接听界面。

/** * Created on 2018/3/29 16:19 * @author baokang.jia * 极光推送广播接收器 */public class JiGuangPushReceiver extends BroadcastReceiver { private static final String TAG = "JPushReceiver"; @Override public void onReceive(Context context, Intent intent) { Bundle bundle = intent.getExtras(); if (bundle == null) { return; } //拿到锁屏管理者 KeyguardManager km = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE); if (km != null && km.isKeyguardLocked()) { //为true就是锁屏状态下 startLoginOrCallActivity(context,bundle); } else { if (JPushInterface.ACTION_REGISTRATION_ID.equals(intent.getAction())) { String regId = bundle.getString(JPushInterface.EXTRA_REGISTRATION_ID); LogUtil.d(TAG, "[MyReceiver] 接收Registration Id : " + regId); //send the Registration Id to yours server... } else if (JPushInterface.ACTION_MESSAGE_RECEIVED.equals(intent.getAction())) { LogUtil.d(TAG, "[MyReceiver] 接收到推送下来的自定义消息: " + bundle.getString(JPushInterface.EXTRA_MESSAGE)); } else if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {//接收到推送下来的通知 //启动通话界面 startLoginOrCallActivity(context, bundle); } else if (JPushInterface.ACTION_NOTIFICATION_OPENED.equals(intent.getAction())) {//点击通知栏 //启动通话界面 startLoginOrCallActivity(context, bundle); //清除所有状态的通知 JPushInterface.clearAllNotifications(context); } else if (JPushInterface.ACTION_RICHPUSH_CALLBACK.equals(intent.getAction())) { LogUtil.d(TAG, "[MyReceiver] 用户收到到RICH PUSH CALLBACK: " + bundle.getString(JPushInterface.EXTRA_EXTRA)); //在这里根据 JPushInterface.EXTRA_EXTRA 的内容处理代码，比如打开新的Activity， 打开一个网页等.. } } } /** * 未登录跳转登录界面， * else 启动通话接听界面 */ private void startLoginOrCallActivity(Context context, Bundle bundle) { //EXTRA_EXTRA String extras = bundle.getString(JPushInterface.EXTRA_EXTRA); String userID = SPUtil.getString(context, Constants.LOGIN_USER_ID); if (TextUtils.isEmpty(userID)) { //启动登录界面 Intent intent = new Intent(context, LoginActivity.class); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent); } else { //启动通话接听界面 int notifyId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID); if (!TextUtils.isEmpty(extras) && extras.contains("androidNotification extras key")){ ReceiveTalkActivity.startReceiveTalkActivity(context, extras,notifyId); } } } }//在AndroidManifest注册全局自定义广播接收器<receiver android:name=".event.JiGuangP`在这里插入代码片`ushReceiver" android:enabled="true" android:exported="false"> <intent-filter> <action android:name="cn.jpush.android.intent.REGISTRATION" /> <!-- Required 用户注册SDK的intent --> <action android:name="cn.jpush.android.intent.MESSAGE_RECEIVED" /> <!-- Required 用户接收SDK消息的intent --> <action android:name="cn.jpush.android.intent.NOTIFICATION_RECEIVED" /> <!-- Required 用户接收SDK通知栏信息的intent --> <action android:name="cn.jpush.android.intent.NOTIFICATION_OPENED" /> <!-- Required 用户打开自定义通知栏的intent --> <action android:name="cn.jpush.android.intent.CONNECTION" /> <!-- 接收网络变化 连接/断开 since 1.6.3 --> <category android:name="${PACKAGE_NAME}" /> </intent-filter> </receiver>

B:启动通话接听界面,启动接听界面后获取当前手机模式

AudioManager audio = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);//手机模式，振动，精英、响铃，更具不同模式振动或者响铃，具体可参考以下的实现代码。//点击接听按钮后跳转腾讯视频通话界面/** * Created on 2019/4/28 16:19 * @author baokang.jia * 视频预审接听界面 */public class ReceiveTalkActivity extends BaseActivity { private static String PUSH_MSG_KEY = "push_msg_key"; private static String NOTIFICATION_ID_KEY = "notification_id_key"; /** * 腾讯云注册分配的appId */ private int sdkAppId = /** * 检查运行时权限 */ private boolean mCheckPermissionResult = false; private PushMsgBean mPushMsgBean; /** * 媒体播放 */ private MediaPlayer mMediaPlayer; /** * 震动 */ private Vibrator mVibrator; @Override protected void onCreate(Bundle savedInstanceState) { Window window = getWindow(); //悬浮窗 WindowViewUtil.setWindowFloatAndScreenOn(window,this); super.onCreate(savedInstanceState); //初始化倒计时器 initCountDownTimer(); //请求权限 requestMustPermission(); initViews(); //根据通知Id清除状态栏对应的通知 JPushInterface.clearAllNotifications(this); //持续震动和响铃 continuedVibratorAndMediaPlayer(); } /** * 60秒后关闭activity */ private void initCountDownTimer() { long time = 30000; long countDownInterval = 1000; CountDownTimer downTimer = new CountDownTimer(time, countDownInterval) { @Override public void onTick(long millisUntilFinished) { } @Override public void onFinish() { finish(); } }; downTimer.start(); } @Override protected int getLayoutId() { return R.layout.activity_receive_talk; } @Override protected boolean initToolbar() { return false; } @Override protected void getIntent(Intent intent) { String pushMsg = getIntent().getStringExtra(PUSH_MSG_KEY); //notificationId = getIntent().getIntExtra(NOTIFICATION_ID_KEY, 0); parsePushMsg(pushMsg); } @Override protected void initViews() { Button btnCancel = findViewById(R.id.btn_cancel_call); Button btnAnswer = findViewById(R.id.btn_answer_call); btnCancel.setOnClickListener(v ->{ mVibrator.cancel(); mMediaPlayer.stop(); finish(); }); btnAnswer.setOnClickListener(v -> { mVibrator.cancel(); mMediaPlayer.stop(); if (mCheckPermissionResult) { Intent intent = new Intent(this, TRTCMainActivity.class); intent.putExtra("roomId", Integer.valueOf(mPushMsgBean.getRoomId())); intent.putExtra("userId", mPushMsgBean.getUserId()); intent.putExtra("sdkAppId", sdkAppId); intent.putExtra("userSig", mPushMsgBean.getUserSig()); startActivity(intent); finish(); } else { ToastUtil.longToast("需要的权限被拒绝，无法开启视频审核"); } }); } /** * 持续响铃和震动 */ private void continuedVibratorAndMediaPlayer() { //获取媒体播放器 mMediaPlayer = new MediaPlayer(); try { mMediaPlayer.setDataSource(this, RingtoneManager .getDefaultUri(RingtoneManager.TYPE_RINGTONE));//这里我用的通知声音，还有其他的，大家可以点进去看 mMediaPlayer.prepare(); } catch (IOException e) { e.printStackTrace(); } //取得震动服务的句柄 mVibrator = (Vibrator)this. getSystemService(VIBRATOR_SERVICE); //获取当前手机模式 AudioManager audio = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); if (audio != null) { switch (audio.getRingerMode()) { case AudioManager.RINGER_MODE_SILENT://静音 //do sth break; case AudioManager.RINGER_MODE_NORMAL://响铃 mMediaPlayer.start(); mMediaPlayer.setLooping(true); //循环播放 break; case AudioManager.RINGER_MODE_VIBRATE://震动 //数组参数意义：第一个参数为等待指定时间后开始震动， //震动时间为第二个参数。后边的参数依次为等待震动和震动的时间 //第二个参数为重复次数，-1为不重复，0为一直震动 if (mVibrator != null) { mVibrator.vibrate( new long[]{1000,1000},0); } break; } } } private void parsePushMsg(String pushMsg) { if (!TextUtils.isEmpty(pushMsg)) { CustomerMsg customerMsg = GsonUtil.fromJson(pushMsg, CustomerMsg.class); String pushMsgContent = customerMsg.getPushMsgContent(); pushMsgContent = pushMsgContent.replace("\\", ""); LogUtil.d(Constants.LOG,"pushMsgContent="+pushMsgContent); mPushMsgBean = GsonUtil.fromJson(pushMsgContent, PushMsgBean.class); } } /** * 申请应用必须的权限 */ private void requestMustPermission() { AndPermission.with(this) .requestCode(Constants.REQUEST_CODE_PERMISSION) .permission( Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.VIBRATE, Manifest.permission.DISABLE_KEYGUARD, Manifest.permission.WAKE_LOCK ) .rationale((requestCode, rationale) -> //再次申请被拒绝的权限 AlertDialog.newBuilder(this) .setTitle(R.string.title_dialog) .setMessage(R.string.message_permission_failed) .setPositiveButton(R.string.ok, (dialog, which) -> { dialog.cancel();

String pushMsg = intent.getStringExtra(PUSH_MSG_KEY); //notificationId = intent.getIntExtra(NOTIFICATION_ID_KEY, 0); parsePushMsg(pushMsg); } /** * 提供给外部调用启动接听界面的activity * * @param cex 上下文对象 * @param pushMsg 消息内容 * @param notifyId 通知id */ public static void startReceiveTalkActivity(Context cex, String pushMsg, int notifyId) { Intent calIntent = new Intent(cex, ReceiveTalkActivity.class); //携带数据 calIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); calIntent.putExtra(PUSH_MSG_KEY, pushMsg); calIntent.putExtra(NOTIFICATION_ID_KEY, notifyId); cex.startActivity(calIntent); } @Override protected void onDestroy() { super.onDestroy(); mMediaPlayer.stop(); mVibrator.cancel(); }}//注册ReceiveTalkActivity， android:launchMode="singleTask"<activity android:name=".trtc.view.ReceiveTalkActivity" android:launchMode="singleTask" android:screenOrientation="portrait" />

总结：项目中考虑时间和成本问题。没有接入IM功能。消息推送不可靠，极光的push进程被杀，是收不到消息。当打开app后，会蹦出很多通知。这只是简易的实现了在pc调起移动端进行视频通话。这有很多因素是没有考虑进去的，在此先记录下吧。
