Android接入腾讯直播（一）

• 小直播

小直播 App 是一套开源的完整的在线直播解决方案，它基于云直播服务、即时通信（IM）和对象存储服务（COS）构建，并使用云服务器（CVM）提供简单的后台服务，可以实现登录、注册、开播、房间列表、连麦互动、文字互动和弹幕消息等功能。

我这边来个最简单的教程：

第一步 下载SDK

Checkout 项目：https://gitee.com/cloudtencent/MLVBSDK
下载下来以后然选择：Android/XiaoZhiBo导入Android Studio即可。

第二步 创建测试license

进入 https://console.cloud.tencent.com/live/license，使用微信或者QQ扫码登录后创建一个测试license即可

第三步 打开小直播项目中TCGlobalConfig.java

填写LICENCE_URL，LICENCE_KEY，APP_SVR_URL 三个值即可。

LICENCE_URL和LICENCE_KEY在第二步创建后会自动生成，填写即可
APP_SVR_URL 统一填写：https://xzb.qcloud.com

第四步 运行项目即可开播

当然仅限快速测试使用，上线需要正式的license和APP_SVR_URL

上线的时候也只需要更新ALICENCE_URL，LICENCE_KEY，APP_SVR_URL即可

• 腾讯云工具包 App

如果您是开发人员，可以直接下载我们的腾讯云工具包 App，工具包 中的每一个菜单项均对应 SDK 中的一项独立功能，您可以根据当前项目需要进行针对性的调试。

第一步 下载SDK

Checkout 项目：https://github.com/tencentyun/LiteAVProfessional_Android/tree/master/Demo
下载下来以后然选择：Demo导入即可。

第二步 创建测试license

进入 https://console.cloud.tencent.com/live/license，使用微信或者QQ扫码登录后创建一个测试license即可

第三步 修改配置

打开项目中DemoApplication.java填写licenceUrl和licenseKey
打开项目中GenerateTestUserSig.java填写BIZID，APPID，SDKAPPID，SECRETKEY

第四步 运行项目即可开播

setVideoQuality方法报错替换如下即可：

 V2TXLiveDef.V2TXLiveVideoEncoderParam param = new V2TXLiveDef.V2TXLiveVideoEncoderParam(Resolution);param.videoResolutionMode = ResolutionMode;mLivePusher.setVideoQuality(param);

demo都跑通了，下面手写一个精简的推流和拉流功能吧。

• 精简推流拉流

主播推流，观众拉流
经过参考demo发现推流有摄像头推流和录屏推流，拉流就一种
推流只有一个推流地址，拉流有多种拉流地址（RTMP,FLV,HLS,低延时）

第一步 初始化

package com.z.zplay;import android.app.Application;import com.tencent.rtmp.TXLiveBase;public class IApplication extends Application {@Overridepublic void onCreate() {super.onCreate();String licenceURL = "https://xxxxxxxxxxxxxxxxxxxxx.license"; String licenceKey = "xxxxxxxxxxxxxxxxxxxxxx"; TXLiveBase.getInstance().setLicence(this, licenceURL, licenceKey);}}

    //otherimplementation 'com.squareup.okhttp3:okhttp:3.6.0'implementation 'com.squareup.retrofit2:retrofit:2.8.2'implementation 'com.king.zxing:zxing-lite:1.1.2'implementation 'org.greenrobot:eventbus:3.1.1'//腾讯直播implementation 'com.tencent.liteav:LiteAVSDK_Professional:latest.release'implementation 'com.tencent.imsdk:imsdk:4.9.1'

    <uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /><uses-permission android:name="android.permission.BLUETOOTH" /><uses-permission android:name="android.permission.CAMERA" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-feature android:name="android.hardware.Camera" /><uses-feature android:name="android.hardware.camera.autofocus" />

第二步 获取拉流推流地址

不管你是要推流还是拉流都要先获取地址

	//腾讯提供的测试地址，正式上线需要换成自己的public static final String URL_FETCH_PUSH_URL = "https://lvb.qcloud.com/weapp/utils/get_test_pushurl";private fun fetchPusherURL() {val okHttpClient = OkHttpClient().newBuilder().connectTimeout(10, TimeUnit.SECONDS).readTimeout(10, TimeUnit.SECONDS).writeTimeout(10, TimeUnit.SECONDS).build()val request = Request.Builder().url(Constants.URL_FETCH_PUSH_URL).addHeader("Content-Type", "application/json; charset=utf-8").build()okHttpClient.newCall(request).enqueue(object : Callback {override fun onFailure(call: Call, e: IOException) {}@Throws(IOException::class)override fun onResponse(call: Call, response: Response) {if (response.isSuccessful) {try {val jsonRsp = JSONObject(response.body()!!.string())val pusherURLDefault = jsonRsp.optString(Constants.URL_PUSH)val rtmpPlayURL = jsonRsp.optString(Constants.URL_PLAY_RTMP)val flvPlayURL = jsonRsp.optString(Constants.URL_PLAY_FLV)val hlsPlayURL = jsonRsp.optString(Constants.URL_PLAY_HLS)val realtimePlayURL = jsonRsp.optString(Constants.URL_PLAY_ACC)startLivePusher(pusherURLDefault,rtmpPlayURL,flvPlayURL,hlsPlayURL,realtimePlayURL)} catch (e: JSONException) {e.printStackTrace()}}}})}private fun startLivePusher(pushURL: String,rtmpPlayURL: String,flvPlayURL: String,hlsPlayURL: String,realtimePlayURL: String) {var intent = Intent()if (clickType == 1) {intent.setClass(this, PushActivity::class.java)} else if (clickType == 2) {intent.setClass(this, ScreenPushActivity::class.java)}intent.putExtra(Constants.INTENT_URL_PUSH, pushURL)intent.putExtra(Constants.INTENT_URL_PLAY_RTMP, rtmpPlayURL)intent.putExtra(Constants.INTENT_URL_PLAY_FLV, flvPlayURL)intent.putExtra(Constants.INTENT_URL_PLAY_HLS, hlsPlayURL)intent.putExtra(Constants.INTENT_URL_PLAY_ACC, realtimePlayURL)startActivity(intent)}

其中pushURL为推流地址，另外4个为拉流地址。

第三步 推流

摄像头推流

录屏推流

package com.z.zplay;import androidx.appcompat.app.AppCompatActivity;import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

}

录屏推流需要多增加一个activity配置

     <activityandroid:name="com.tencent.rtmp.video.TXScreenCapture$TXScreenCaptureAssistantActivity"android:theme="@android:style/Theme.Translucent" />

第四步 拉流

package com.z.zplay;import androidx.appcompat.app.AppCompatActivity;import android.os.Bundle;
import android.util.Log;import com.tencent.live2.V2TXLiveDef;
import com.tencent.live2.V2TXLivePlayer;
import com.tencent.live2.impl.V2TXLivePlayerImpl;
import com.tencent.rtmp.ui.TXCloudVideoView;public class GetPushActivity extends AppCompatActivity {//这个URL就是推流生成的二维码的数据private String mPlayURL = "";private V2TXLivePlayer mLivePlayer;               //直播拉流的视频播放器private TXCloudVideoView mVideoView;private V2TXLiveDef.V2TXLiveFillMode mRenderMode = V2TXLiveDef.V2TXLiveFillMode.V2TXLiveFillModeFit;    //Player 当前渲染模式private V2TXLiveDef.V2TXLiveRotation mRenderRotation = V2TXLiveDef.V2TXLiveRotation.V2TXLiveRotation0;         //Player 当前渲染角度@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_get_push);mPlayURL = getIntent().getStringExtra(Constants.INTENT_URL);mVideoView = (TXCloudVideoView) findViewById(R.id.liveplayer_video_view);mLivePlayer = new V2TXLivePlayerImpl(this);startPlay();}private void startPlay() {String playURL = mPlayURL;mLivePlayer.setRenderView(mVideoView);mLivePlayer.setRenderRotation(mRenderRotation);mLivePlayer.setRenderFillMode(mRenderMode);mLivePlayer.startPlay(playURL);}
}

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".GetPushActivity"><com.tencent.rtmp.ui.TXCloudVideoViewandroid:id="@+id/liveplayer_video_view"android:layout_width="match_parent"android:layout_height="match_parent" /></FrameLayout>

第五步 运行即可，可配合腾讯云工具包 App一块测试

以上都是最精简的可跑通的核心代码，其他配置的比如声道，美颜等按需增加。
推流和拉流不包含在直播间聊天的功能，如果需要聊天，那么需要增加腾讯云IM服务SDK

其他配置请参考：官方文档
腾讯直播Demo

• 即时通信IM

第一步 下载SDK

Checkout 项目：https://github.com/tencentyun/TIMSDK/tree/master/Android/Demo
下载下来以后然选择：Demo导入Android Studio即可。

第二步 创建测试应用

登录 即时通信 IM 控制台创建一个应用

第三步 配置

GenerateTestUserSig.java填写SDKAPPID，SECRETKEY即可

第四步 运行项目即可登录聊天和开播
