java.lang.IllegalArgumentException: FocusMode mode manual is not supported. Samsung Grand Prime

[sefaaycicek]

Hi, I tried different methods with different devices. Camera starts successfully on Samsung Note 5 but it always crash on Samsung Grand Prime(Android 6.0).

This is create method. I set focus mode correctly.

private Fotoapparat createFotoapparat() {
        return Fotoapparat
                .with(this)
                .into(cameraView)
                .previewScaleType(ScaleType.CenterCrop)
                .lensPosition(back())
                .focusMode(firstAvailable(continuousFocusPicture(),autoFocus(),fixed()))
                .logger(loggers(
                        logcat(),
                        fileLogger(this)
                ))
                .cameraErrorCallback(new Function1<CameraException, Unit>() {
                    @Override
                    public Unit invoke(CameraException e) {
                        Toast.makeText(TestActivity.this, e.toString(), Toast.LENGTH_LONG).show();
                        return null;
                    }
                })
                .build();
    }

Crash log says that Focus mode manuel is not supported.

• This crash is for Samsung Grand Prime. This code work on Samsung Note 5.
• We already used 1.5.0 version on same device with same parameters. And it work with no problem. We want to change sdk because of 1.5.0 focus stability problem.

Also we tried to set configuration manually as below code.

        fotoapparat = createFotoapparat();
        fotoapparat.updateConfiguration(cameraConfiguration);

Configuration instance is here.

 private CameraConfiguration cameraConfiguration = CameraConfiguration
            .builder()
            .photoResolution(standardRatio(
                    highestResolution()
            )).focusMode(firstAvailable(
                    continuousFocusPicture(),
                    autoFocus(),
                    fixed()

            )).flash(firstAvailable(
                    autoRedEye(),
                    autoFlash(),
                    torch(),
                    off()
            )).previewFpsRange(highestFps())
            .sensorSensitivity(highestSensorSensitivity())
            .build();

Hey @sefaaycicek, thanks for opening a separate issue again! Could you also please paste the exact stacktrace? It would help us a lot.

My assumption so far is that Samsung Grand Prime violates the possible values of the Android camera Api and also returns manual which is not in the expected set of values. Instead of crashing the app we can simply find a way to ignore this value, but let's check first the stacktrace

I made a blind fix. Try 2.0.0-beta3 2.0.0-beta5, should work I think

I will assume this fixed with 2.0.0-beta5. Feel free to comment if you have further problems
