Not View Camera

[jackeykabra]

ActivityJava file: it works perfectly in the SM-T231 device.

MainActivity.kt file: A camera does not display in the SM-T231 device version is 4.4.2 only blank screen is displaying.

When we click on capture button image is display in image view but an orientation problem occurs in this device. I have no change on your existing library code.

 val imageView = findViewById<ImageView>(R.id.result)
 imageView.setImageBitmap(it.bitmap)
 imageView.rotation = (-it.rotationDegrees).toFloat()

I have checked two more device it will worked perfectly. the device is Moto g4 plus and HTC One M9PLUS.

Can you please solve it. Thank you

How did you initialize FA?

Those 2 activities have different default configurations that your device might not support.

// This is for Kt:
    CameraConfiguration(
                    previewResolution = firstAvailable(
                            wideRatio(highestResolution()),
                            standardRatio(highestResolution())
                    ),
                    previewFpsRange = highestFps(),
                    flashMode = off(),
                    focusMode = firstAvailable(
                            continuousFocusPicture(),
                            autoFocus()
                    ),
                    frameProcessor = {
                        // Do something with the preview frame
                    }
    )

// This is for java:
    CameraConfiguration
            .builder()
            .photoResolution(standardRatio(
                    highestResolution()
            ))
            .focusMode(firstAvailable(
                    continuousFocusPicture(),
                    autoFocus(),
                    fixed()
            ))
            .flash(firstAvailable(
                    autoRedEye(),
                    autoFlash(),
                    torch(),
                    off()
            ))
            .previewFpsRange(highestFps())
            .sensorSensitivity(highestSensorSensitivity())
            .frameProcessor(new SampleFrameProcessor())
            .build();

I haven't any changed in exiting MainActivity.kt file again I checked after you posted a comment but the still same problem that device as I mentioned as above comment.

Initialize FA:

// This is for Kt:
private sealed class Camera(
    val lensPosition: LensPositionSelector,
    val configuration: CameraConfiguration
) {

object Back : Camera(
        lensPosition = back(),
        configuration = CameraConfiguration(
                previewResolution = firstAvailable(
                        wideRatio(highestResolution()),
                        standardRatio(highestResolution())
                ),
                previewFpsRange = highestFps(),
                flashMode = off(),
                focusMode = firstAvailable(
                        continuousFocusPicture(),
                        autoFocus()
                ),
                frameProcessor = {
                    // Do something with the preview frame
                }
        )
)

object Front : Camera(
        lensPosition = front(),
        configuration = CameraConfiguration(
                previewResolution = firstAvailable(
                        wideRatio(highestResolution()),
                        standardRatio(highestResolution())
                ),
                previewFpsRange = highestFps(),
                flashMode = off(),
                focusMode = firstAvailable(
                        fixed(),
                        autoFocus()
                )
        )
)

}
