Share Image or File on Android

Java Sample

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage);
shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.send_to)));
//or remove createChooser to show a dialog with remember button

My Own Kotlin Sample

    private fun imageButtonShare_OnClick(v: View) {

        val uri = Uri.fromFile(File(path))
        val intent = Intent(Intent.ACTION_SEND)
        intent.putExtra(Intent.EXTRA_STREAM, uri)
        intent.setType(getMimeType(path))
        startActivity(Intent.createChooser(intent,"Share"))
    }

    fun getMimeType(url: String): String? {
        var type: String? = null
        val extension = MimeTypeMap.getFileExtensionFromUrl(url)
        if (extension != null) {
            type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension)
        }
        return type
    }
