Description

I am working on RTSP client now, I got the frame from my RTSP server, but have no idea how to display it in Android. My idea is to use JavaCameraView and replace the origin data with my processed frame, but I didn't find JavaCameraView in my package(maybe because installation missed that part?), and I tried to use ImageView and doesn't work too.

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.example.rtsp, PID: 3254 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.rtsp/com.example.rtsp.MainActivity}: android.view.InflateException: Binary XML file line #9: Binary XML file line #9: Error inflating class org.opencv.android.JavaCameraView at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2778) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2856)

Is there any suggestion for display frames to screen in Android?

Research direction
Check if the OpenCV Android SDK is correctly linked and if JavaCameraView is available in the build. Ensure the OpenCV library is initialized before using JavaCameraView.
