here I'm sharing the image intent. The image is in a drawable folder.
Giving this excpetion.
android.os.FileUriExposedException:

file:///storage/emulated/0/Android/data/com.example.arkkhano.myapplication/cache/myImage.png exposed beyond app through ClipData.Item.getUri()

at android.os.StrictMode.onFileUriExposed(StrictMode.java:1958)

at android.net.Uri.checkFileUriExposed(Uri.java:2356)

The code:

sharing_img.setOnClickListener {

    val myDrawable = tv_view_home2e.drawable

    val bitmap = (myDrawable as BitmapDrawable).bitmap

    val file = File(externalCacheDir,"myImage.png")

    val fOut = FileOutputStream(file)

    bitmap.compress(Bitmap.CompressFormat.PNG,90,fOut)

    fOut.flush()

    fOut.close()

    file.setReadable(true,false)

    val intent = Intent(Intent.ACTION_SEND)

    intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK

    intent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(file))

    intent.type = "image/png"

    intent.putExtra(Intent.EXTRA_SUBJECT,"Subject here")

    startActivity(Intent.createChooser(intent,"Share to "))

}

According to Android document, you should use FileProvider

https://developer.android.com/reference/android/support/v4/content/FileProvider

but when I tried, it works on some device and doesn't work on other devices.

So a safe way for me is export the file to somewhere external storage (Environment.getExternalStorageDirectory) first, and share to other apps. That works for all my devices.
