How to use JetPack-CameraX-Android?

JetPack-CameraX helps you add reliable camera to your app quickly. It use cameraX library inside.Simple implementation.

Implement camera in app is so common today, i.e. especially provide use to click and upload his profile image. However writing your code to handle all this is a tedious job. So JetPack-CameraX helps you with all the hard job. You just need first add the library to your app.gradle file.

implementation 'com.github.SaeculumSolutions:Jetpack-CameraX-Android:1.0.0'

And also make sure you in your project.gradle file you add below dependency

allprojects {
 repositories {
  ...
  maven { url 'https://jitpack.io' }
 }
}

After that, in your code(perhaps MainActivity class), just initialise intent

companion object {
		private const val TAG = "MainActivity"
		const val LAUNCH_CAMERA_X_ACTIVITY = 131  
}


override fun onCreate(savedInstanceState: Bundle?) {
...
		val intent = JetPackCameraX(this).build()
		/*
     		*  if you want open front camera as default use this
	     	*  val intent = JetPackCameraX(this).setCameraLensFacingFront(true).build()
     		*/
		startActivityForResult(intent, LAUNCH_CAMERA_X_ACTIVITY)

}

Then override onActivityResult function to get JetPackCameraX result.

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
            super.onActivityResult(requestCode, resultCode, data)
            if (resultCode == Activity.RESULT_OK && data != null) {
                when (requestCode) {
                    LAUNCH_CAMERA_X_ACTIVITY -> {
                    if (data != null) {
                        val path: String = data.extras?.get(CameraXImage.GET_CLICKED_IMAGE_URI).toString()
                        Log.d(TAG, "onActivityResult: $path" )
                        // Do needful with your selectedMedia
                       }
                    }
