Custom options for intent chosoer

2019-06-30

In our day to day Android app development work. In most scenarios we have to provide action selection dialog for various Intent. Here is a alternative to custom a dialog, use a chooser Intent to create System provided selection dialog with custom selection.

The result on Android P

We can do it by

startActivity(Intent.createChooser(
	Intent(MediaStore.ACTION_IMAGE_CAPTURE), // base Intent
	"Title here"
).apply {
	putExtra(
		Intent.EXTRA_INITIAL_INTENTS,
		arrayOf(
			Intent(ACTION_GET_CONTENT).also { // extra Intent
			it.type = "images/*"
			}
		)
	)
})

Alternative

It`s there alternative for this? Seems the implementation a little bit complex which we may create simple wrapper in all of our project. Here you go, Aura, An Android library created by myself which provide ChooserIntent class to generate the chooser Intent. And make our work slightly simpler.

startActivity(ChooserIntent(
    "Title here",
    Intent(MediaStore.ACTION_IMAGE_CAPTURE),
    Intent(ACTION_GET_CONTENT).also{
         it.type = "images / *"
    }
).value())
