Keep closing and opening the camera, the program will crash after running for a period of time #529

Code for opening the camera：

public boolean startCam() { mUSBMonitor =new USBMonitor(mContext,mOnDeviceConnectListener); mUSBMonitor.register(); filter = DeviceFilter.getDeviceFilters(mContext, device_filter_id); if (filter.size() > 0){ item = mUSBMonitor.getDeviceList(filter.get(0)); if (item.size() > 0){ for(int i=0; i< item.size(); i++) { for (int c=0; c<8; c++) { if (item.get(i).getVendorId() == arrayCamPro[c].vid && item.get(i).getProductId() == arrayCamPro[c].pid) { mUSBMonitor.requestPermission(item.get(i)); if (!mUSBMonitor.hasPermission(item.get(i))){ OpenUSBCamThread.start(); break; } } } } }else { //callback.openFail(); return false; } }else { //callback.openFail(); return false; } return true; }

Code to turn off the camera：

public void closeCam() { if (mUVCCamera != null) { mUVCCamera.stopPreview(); mUVCCamera.destroy(); mUVCCamera = null; } if (mUSBMonitor != null) { mUSBMonitor.unregister(); mUSBMonitor.destroy(); mUSBMonitor = null; } }
