CAMERA APPLICATION NAME AND VERSION: Any

ANDROID OS BUILD NUMBER: Any

DEVICE NAME: Any

DESCRIPTION:

I have implemented my own subclass of ImageAnalysis.Analyzer and it works as expected. Now I want to "attach/detach" this analyzer to the ImageAnalysis class dynamically (based on some user actions). From the ImageAnalysis API it looks like it is possible, there is setAnalyzer method and also clearAnalyzer method. However, this works correctly only on the first setAnalyzer call. If I call then clearAnalyzer and setAnalyzer again, analyze method is not called.

STEPS TO REPRODUCE:
1. Call setAnalyzer. analyze method is called with images - correct
2. Call clearAnalyzer. analyze method is not called - correct
3. Call setAnalyzer. analyze method is not called - incorrect

OBSERVED RESULTS:
After clear/set analyzer calls, analyze method is not called

EXPECTED RESULTS:
After clear/set analyzer calls, analyze method is called again

REPRODUCIBILITY: Always
