**1.找到****TestSendCustomCameraData****.java文件,添加如下变量:** ``` private BaseBeautyViewHolder mBeautyViewHolder; private MHBeautyManager mhBeautyManager; ``` **找到****onTextureProcess****方法,添加美颜处理代码:** ``` @Override public int onTextureProcess(int textureId, EGLContext eglContext) {     if (!mIsSending) return textureId;     if(mBeautyViewHolder==null){         return textureId;     }     if (mhBeautyManager == null) {         mhBeautyManager = new MHBeautyManager(mContext,true);         mhBeautyManager.setBeautyDataModel(BeautyDataModel.getInstance());         if (mBeautyViewHolder != null) {             mBeautyViewHolder.setMhBeautyManager(mhBeautyManager);         }         return textureId;     }     int newTex = mhBeautyManager.render(textureId, mCameraHeight, mCameraWidth);     //将视频帧通过纹理方式塞给SDK     TRTCCloudDef.TRTCVideoFrame videoFrame = new TRTCCloudDef.TRTCVideoFrame();     videoFrame.texture = new TRTCCloudDef.TRTCTexture();     videoFrame.texture.textureId = newTex;     videoFrame.texture.eglContext14 = eglContext;     videoFrame.width = mCameraHeight;     videoFrame.height = mCameraWidth;     videoFrame.pixelFormat = TRTCCloudDef.TRTC_VIDEO_PIXEL_FORMAT_Texture_2D;     videoFrame.bufferType = TRTCCloudDef.TRTC_VIDEO_BUFFER_TYPE_TEXTURE;     mTRTCCloud.sendCustomVideoData(videoFrame);     return textureId; } ``` **找到****onSurfaceTextureDestroy****方法,销毁美颜管理类对象:** ``` @Override public void onSurfaceTextureDestroy(SurfaceTexture surfaceTexture) {     Log.d(TAG, "onSurfaceTextureDestroy: " + Thread.currentThread().getName());     if(mhBeautyManager!=null){         mhBeautyManager.destroy();     } } ``` **添加****getMHBeautyManager****方法:** ``` public MHBeautyManager getMHBeautyManager(){     return mhBeautyManager; } ``` **2.找到****TRTCMainActivity****.java文件** **实现****DefaultBeautyEffectListener****接口。代码如下:** ``` @Override public void onFilterChanged(FilterBean filterBean) {     if (mhBeautyManager == null) {         return;     }     FilterEnum filterEnum = filterBean.getFilterEnum();     if (filterEnum == FilterEnum.PRO_FILTER) {         mhBeautyManager.changeDynamicFilter(filterBean.getmFilterName());     } else {         Bitmap lookupBitmap = BitmapUtil.getFilterBitmap(this,filterEnum);         mhBeautyManager.setFilter(lookupBitmap);     } } @Override public void onMoPiChanged(int progress) {     if (mCustomCameraCapture!=null&&mCustomCameraCapture.getMHBeautyManager() != null) {         mCustomCameraCapture.getMHBeautyManager().setSkinSmooth(progress);     } } @Override public void onFengNenChanged(int progress) {     if (mCustomCameraCapture!=null&&mCustomCameraCapture.getMHBeautyManager() != null) {         mCustomCameraCapture.getMHBeautyManager().setSkinTenderness(progress);     } } @Override public void onBeautyOrigin() {     if (mCustomCameraCapture!=null&&mCustomCameraCapture.getMHBeautyManager() != null) {         mCustomCameraCapture.getMHBeautyManager().setSkinWhiting(0);         mCustomCameraCapture.getMHBeautyManager().setSkinSmooth(0);         mCustomCameraCapture.getMHBeautyManager().setSkinTenderness(0);     } } ``` ** 添加如下变量** ``` private Handler mHandler; private AlertDialog dialog; private RelativeLayout beautyContainer; private BaseBeautyViewHolder beautyViewHolder; private boolean isResume; private int retryCount; private Thread beautyThread; ``` **添加如下代码** ``` static class DiaLogListener implements DialogInterface.OnClickListener {         WeakReference activityWeakReference;
