Sharesheet

Android share sheet allow you to share media such as text, image with other app via a simple system sheet

Text

val sendIntent: Intent = Intent().apply {
    action = Intent.ACTION_SEND
    putExtra(Intent.EXTRA_TEXT, "This is my text to send.")
    type = "text/plain"
}

val shareIntent = Intent.createChooser(sendIntent, null)
startActivity(shareIntent)

Image

to share image with other app, we need to setup a Content Provider

val provider =
    FileProvider.getUriForFile(context, "${context.packageName}.provider", targetFile)

val shareIntent = Intent(Intent.ACTION_SEND).apply {
    putExtra(Intent.EXTRA_STREAM, provider) // real data being share
    type = "image/jpeg"

    addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION) // allow display preview
    clipData = ClipData.newRawUri(targetFile.name, provider) // for preview image
}

context.startActivity(Intent.createChooser(shareIntent, null))
