上一篇文章介绍了环信的解决方案，见Android 即时音视频解决方案1——环信，这篇文章，介绍一下更加靠谱，也就是腾讯云的解决方案，毕竟腾讯是是这方面的头头，比较靠谱。当然，集成腾讯云比集成环信稍微复杂那么一点，需要有一点点的耐心。

官方地址音视频云通信 AVC

SDK下载AV Andriod1.3

文档地址音视频云通讯

先讲讲腾讯云的原理，使用腾讯云的时候，要有一个账号体系，这个账号体系比较灵活，可以使用独立模式也可以只用第三方账号体系，这里使用独立模式。

使用独立模式，要使用腾讯云的服务的时候，我们无需将用户的账号密码同步到腾讯，但是我们的服务端需要进行一定的处理。用户在APP客户端输入帐号密码后到APP自有帐号登录服务器验证，验证成功后自有帐号登录服务器使用私钥派发签名（sig）给客户端；客户端提交用户帐号和私钥签名IM云（通过IMSDK或者音视频SDK接口），验证签名成功后向终端派发相应票据，进而使用IM云服务。

开发者需要保证私钥安全，腾讯完全信赖私钥签名；签名有效期由开发者指定，并加密在私钥签名中；该集成方式无需将APP自有帐号的帐号密码同步腾讯，最大程度保证开发者用户数据的私密性。

下面贴出官方文档的一个例子说明

假设开发者开发的APP为天天互动，天天互动自有服务器（开发自己开发）支持用户注册功能，同时天天互动接入了腾讯音视频通讯服务。某一天用户A在天天互动注册了帐号，登录天天互动后使用腾讯的音视频服务与家人视频。那么天天互动是如何实现这一功能呢？下面描述具体登录流程： - 用户A在天天互动的客户端输入自己的帐号及密码后，客户端传给天天互动的帐号服务器进行验证； - 天天互动的帐号服务器验证用户A的信息成功后，使用天天互动的私钥通过TLS提供的后台API生成签名（sig）； - 天天互动的帐号服务器将生成的签名派发给天天互动的客户端； - 天天互动的客户端使用音视频云通讯相关服务时，需要提交帐号类型（accounttype）、sdkappid、identifier（也就是我们常说的用户id）和签名（由天天互动账号服务器调用TLS后台API生成并派发的）到音视频SDK或者IMSDK的login接口进行验证，验证成功后即可使用相关服务。

下面我们进行服务器端的编码

几个有用的文档和链接 - TLS后台API开发指引 - windows 64位 API - 音视频云通讯账号登录集成

服务器端签名的函数，这里使用PHP

当然你还需要将服务器sdk中的signarure.exe放到当前目录下，此外还有私钥

当我们服务接收到客户端请求时，登陆成功后会进行签名，需要将签名下发到客户端，客户端利用该签名向腾讯服务器验证

签名的参数在腾讯云的后台管理可以看到

这里写图片描述

注意有一个时间戳参数，该参数代表多久之后过期，由开发者控制。

接下来就是客户端的事了。首先就是集成

这里写图片描述

权限

声明组件

App类的内容很简单，就是获得QavsdkControl

public class App extends Application{ private QavsdkControl mQavsdkControl = null; @Override public void onCreate() { super.onCreate(); mQavsdkControl = new QavsdkControl(this); } public QavsdkControl getQavsdkControl() { return mQavsdkControl; } }

然后需要拷几个现成的类

这里写图片描述

你需要修改内容，让他不报错，大部分都是资源相关的东西。

然后需要修改两个变量，共两处，值在腾讯云后台获得

这里写图片描述

客户端的注册功能由开发者自己实现，因为腾讯云不干涉注册，而登陆需要先登录自己的服务器，然后拿签名向腾讯服务器验证。

private void login() { String u=username.getText().toString(); String p=password.getText().toString(); if (TextUtils.isEmpty(u)||TextUtils.isEmpty(p)){ Toast.makeText(getApplicationContext(),"账号或密码不能为空！",Toast.LENGTH_LONG).show(); return ; } //首先登录自己的服务器 //自己服务器登录成功后，服务器需要返回rsa加密后的串 RequestBody requestBody= new FormEncodingBuilder() .add("username",u) .add("password",p) .build(); String url="http://10.0.0.24/tencent/index.php"; Request request=new Request.Builder().url(url).post(requestBody).build(); mOkHttpClient.newCall(request).enqueue(new Callback() { @Override public void onFailure(Request request, IOException e) { Log.e("TAG", "Error,register failure."); } @Override public void onResponse(Response response) throws IOException { String result = response.body().string(); LoginModel bean = gson.fromJson(result, LoginModel.class); Message message = Message.obtain(); message.obj = bean; message.what = LOGIN; mHandler.sendMessage(message); } }); //获得rsa加密串后发起音视频前需要向腾讯服务器验证。 } private Handler mHandler=new Handler(){ @Override public void handleMessage(Message msg) { switch (msg.what){ case LOGIN: LoginModel bean= (LoginModel) msg.obj; if (bean.getStatus()==200){ sign=bean.getMessage(); //保存sign Log.e("TAG","sign:"+sign); Toast.makeText(getApplicationContext(),"登录成功,请稍后！",Toast.LENGTH_LONG).show(); startTencentContext(); }else{ Toast.makeText(getApplicationContext(),"登录失败！"+bean.getMessage(),Toast.LENGTH_LONG).show(); } break; default: break; } super.handleMessage(msg); } };

登陆成功后就可以拿到该签名了。之后开始向腾讯服务验证

private void startTencentContext() { //发起音视频前需要向腾讯服务器验证。 String u=username.getText().toString(); String p=password.getText().toString(); if (TextUtils.isEmpty(u)||TextUtils.isEmpty(p)){ Toast.makeText(getApplicationContext(),"账号或密码不能为空！",Toast.LENGTH_LONG).show(); return ; } if(TextUtils.isEmpty(sign)){ Toast.makeText(MainActivity.this, "请先登录", Toast.LENGTH_SHORT).show(); return ; } if (!mQavsdkControl.hasAVContext()) { if (!mQavsdkControl.isDefaultAppid()) { Toast.makeText(getApplicationContext(), getString(R.string.help_msg_appid_not_default), Toast.LENGTH_LONG).show(); } if (!mQavsdkControl.isDefaultUid()) { Toast.makeText(getApplicationContext(), getString(R.string.help_msg_uid_not_default), Toast.LENGTH_LONG).show(); } mLoginErrorCode = mQavsdkControl.startContext(u, sign); if (mLoginErrorCode != AVConstants.AV_ERROR_OK) { Toast.makeText(getApplicationContext(),"错误码:"+mLoginErrorCode, Toast.LENGTH_LONG).show(); } } }

验证的结果是广播异步返回的，因此我们需要注册一个广播接收器，接收这个消息

private void initStartContextBroadcast() { IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(Util.ACTION_START_CONTEXT_COMPLETE); intentFilter.addAction(Util.ACTION_CLOSE_CONTEXT_COMPLETE); registerReceiver(mStartContextBroadcastReceiver, intentFilter); } private BroadcastReceiver mStartContextBroadcastReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); Log.e("TAG", "WL_DEBUG onReceive action = " + action); Log.e("TAG", "WL_DEBUG ANR StartContextActivity onReceive action = " + action + " In"); if (action.equals(Util.ACTION_START_CONTEXT_COMPLETE)) { mLoginErrorCode = intent.getIntExtra( Util.EXTRA_AV_ERROR_RESULT, AVConstants.AV_ERROR_OK); if (mLoginErrorCode == AVConstants.AV_ERROR_OK) { Intent i=new Intent(MainActivity.this,CallActivity.class); Bundle bundle=new Bundle(); bundle.putString("from",username.getText().toString()); i.putExtras(bundle); startActivity(i); } else { Toast.makeText(getApplicationContext(), getString(R.string.help_msg_login_error), Toast.LENGTH_LONG).show(); } } else if (action.equals(Util.ACTION_CLOSE_CONTEXT_COMPLETE)) { } Log.e("TAG", "WL_DEBUG ANR StartContextActivity onReceive action = " + action + " Out"); } };

之后我们就跳到了另外一个Activity当中，这个Activity中用来处理发起视频通话，处理通话失败等特殊情况的逻辑了，基本上直接从原Demo中复制代码修改即可，直接看代码

public class CallActivity extends AppCompatActivity implements View.OnClickListener{ private String from; private EditText to; private Button video,voice; private QavsdkControl mQavsdkControl; private int mCreateRoomErrorCode = AVConstants.AV_ERROR_OK; private int mCloseRoomErrorCode = AVConstants.AV_ERROR_OK; private int mAcceptErrorCode = AVConstants.AV_ERROR_OK; private int mInviteErrorCode = AVConstants.AV_ERROR_OK; private int mRefuseErrorCode = AVConstants.AV_ERROR_OK;

mSelfIdentifier = intent.getStringExtra(Util.EXTRA_SELF_IDENTIFIER); mReceiveIdentifier = identifier; long roomId = intent.getLongExtra(Util.EXTRA_ROOM_ID, -1); mAcceptErrorCode = intent.getIntExtra( Util.EXTRA_AV_ERROR_RESULT, AVConstants.AV_ERROR_OK); if (mAcceptErrorCode == AVConstants.AV_ERROR_OK) { mQavsdkControl.enterRoom(roomId, identifier, mIsVideo); } else { Toast.makeText(CallActivity.this,R.string.accept_failed,Toast.LENGTH_SHORT).show(); } } else if (action.equals(Util.ACTION_CLOSE_ROOM_COMPLETE)) { } else if (action.equals(Util.ACTION_INVITE_ACCEPTED)) { startActivity(mReceiveIdentifier,mSelfIdentifier); } else if (action.equals(Util.ACTION_INVITE_CANCELED)) { Toast.makeText(getApplicationContext(), R.string.invite_canceled_toast, Toast.LENGTH_LONG).show();

if (mInviteErrorCode == AVConstants.AV_ERROR_OK) { //等待对方接受邀请 Toast.makeText(getApplicationContext(), R.string.dialog_waitting_title, Toast.LENGTH_LONG).show(); } else { //邀请失败 Toast.makeText(getApplicationContext(), R.string.invite_failed, Toast.LENGTH_LONG).show(); closeRoom(); } } else if (action.equals(Util.ACTION_INVITE_REFUSED)) { Toast.makeText(getApplicationContext(), R.string.invite_refused_toast, Toast.LENGTH_LONG).show(); } else if (action.equals(Util.ACTION_RECV_INVITE)) { if (isSender) { Toast.makeText(getApplicationContext(), R.string.notify_conflict, Toast.LENGTH_LONG).show(); } isReceiver = true; mIsVideo = intent.getBooleanExtra(Util.EXTRA_IS_VIDEO, false); new AlertDialog.Builder(CallActivity.this) .setTitle(R.string.invite_title) .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { mQavsdkControl.accept(); } }) .setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int whichButton) { mQavsdkControl.refuse(); isSender = isReceiver = false; } }) .setOnCancelListener( new DialogInterface.OnCancelListener() { @Override public void onCancel(DialogInterface dialog) { Log.e("TAG", "WL_DEBUG onCancel"); mQavsdkControl.refuse(); isSender = isReceiver = false; } }).create().show(); } else if (action.equals(Util.ACTION_REFUSE_COMPLETE)) { mRefuseErrorCode = intent.getIntExtra( Util.EXTRA_AV_ERROR_RESULT, AVConstants.AV_ERROR_OK); if (mRefuseErrorCode != AVConstants.AV_ERROR_OK) { Toast.makeText(getApplicationContext(), R.string.refuse_failed, Toast.LENGTH_LONG).show(); } } else if (action.equals(Util.ACTION_ROOM_CREATE_COMPLETE)) { mCreateRoomErrorCode = intent.getIntExtra( Util.EXTRA_AV_ERROR_RESULT, AVConstants.AV_ERROR_OK); if (mCreateRoomErrorCode != AVConstants.AV_ERROR_OK) { Toast.makeText(getApplicationContext(), R.string.create_room_failed, Toast.LENGTH_LONG).show();

} else { startActivity(mReceiveIdentifier,mSelfIdentifier); } } Log.e("TAG", "WL_DEBUG ANR CreateRoomActivity onReceive action = " + action + " Out"); } }; private void closeRoom() { mCloseRoomErrorCode = mQavsdkControl.exitRoom(); if (mCloseRoomErrorCode != AVConstants.AV_ERROR_OK) { Toast.makeText(CallActivity.this,R.string.close_room_failed,Toast.LENGTH_SHORT).show(); } } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_call); initIntent(); initView(); initInviteBroadcast(); mQavsdkControl = ((App) getApplication()).getQavsdkControl(); } private void initIntent() { Intent intent=getIntent();

这样就差不多可以跑一个试试了。

这里写图片描述

其他细节看腾讯的文档把，多看几次就能把握个大概了。
