Android高通 8.1 老化apk打开摄像头花屏问题

1、最近由于公司VR 3D系统要做双Camera老化测试apk，同时老化4小时需要轮询切换二个摄像头，保证后面camera标定精度数据更准确。

2、一开始我尝试用之前方案移植过去然后同时打开双摄像头突然发现花屏如下图所示

3、于是一第一时间想到是不是分辨率不兼容或者硬件Camera问题或者找驱动确认驱动确认结果2D系统没有问题，于是我交叉验证换了一台机器跟硬件结果还是花屏，因为之前也处理类似的case，于是我自己尝试修改固定的分辨率1280*720 (720P)代码如下（这里只是部门代码github上面也有很多camera源码以及骁龙相机源码大家可以下载自行研究)

   private val mStateCallback2: CameraDevice.StateCallback =object : CameraDevice.StateCallback() {override fun onOpened(camera: CameraDevice) {Log.i(TAG, "StateCallback！ onOpened 2")mCameraDevice2 = camera // 打开成功，保存代表相机的CameraDevice实例val surfaceTexture = mTextureView2!!.surfaceTexturesurfaceTexture.setDefaultBufferSize(1280, 720) //3264X2448(800万)val surface = Surface(surfaceTexture)val previewList = ArrayList<Surface>()previewList.add(surface)try {// 6.将TextureView的surface传递给CameraDevicemCameraDevice2!!.createCaptureSession(previewList,object : CameraCaptureSession.StateCallback() {override fun onConfigured(session: CameraCaptureSession) {try {val builder =mCameraDevice2!!.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW)builder.addTarget(surface) // 必须设置才能正常预览val captureRequest = builder.build()// 7.CameraCaptureSession与CaptureRequest绑定（这是最后一步，已可显示相机预览）session.setRepeatingRequest(captureRequest, null, null)mHandler.removeMessages(CAMERA_RELEASE)mHandler.sendEmptyMessageDelayed(CAMERA_RELEASE,delayTwoSeconds)} catch (e: CameraAccessException) {Log.e(TAG,"createCaptureRequest error = " + e.message)}}override fun onConfigureFailed(session: CameraCaptureSession) {Log.e(TAG, "onConfigureFailed")LogUtils.e("Camera2异常")Toast.makeText(requireContext(),"Camera2异常,请检查设备!", Toast.LENGTH_LONG).show()}},null)} catch (e: CameraAccessException) {Log.e(TAG, "createCaptureSession error = " + e.message)}}override fun onDisconnected(camera: CameraDevice) {Log.e(TAG,"StateCallback！ onDisconnected camera.getId() = " + camera.id)releaseCamera()}override fun onError(camera: CameraDevice, error: Int) {Log.e(TAG,"StateCallback camera.getId() = " + camera.id + " , error = " + error)LogUtils.e("Camera2异常")Toast.makeText(requireContext(),"Camera2异常,请检查设备!", Toast.LENGTH_LONG).show()releaseCamera()}}

4、一开始花屏抓的logcat 错误如下
