Compile error while setting imageAnalysis.setAnalyzer()

Question

I\'m creating a tool to capture every frame from preview using cameraX (for face recognition purpose)

I found that using ImageAnalysis was the way to go.

Answer 1

You can also find the implementation in the official CameraX sample app: CameraFragment.kt.

The part which you need is this:

// Executor field
private lateinit var analysisExecutor: Executor

// in onCreate()
analysisExecutor = Executors.newSingleThreadExecutor()

// after initializing imageAnalysis
imageAnalysis.setAnalyzer(analysisExecutor, ImageAnalysis.Analyzer {
    // TODO analyze
})

If you're wondering whether to use Executors.newSingleThreadExecutor(), Executors.newFixedThreadPool(n) or something else, take a look at the Executors documentation.
