restart android application programmatically

ActivityRestart.kt

fun triggerRestart(context: Activity) {
    val intent = Intent(context, MainActivity::class.java)
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    context.startActivity(intent)
    if (context is Activity) {
        (context as Activity).finish()
    }
    Runtime.getRuntime().exit(0)
}

Works like a charm for Andriod 10

Yes, great work. This would also reload the Application class - so it is an app restarter.

Also I use it as an extension function fun Activity.triggerRestart

Is it possible if the User exists the App that it will automatically restart?

@danielehrhardt I think it should work, but haven't tested it yet

You could at least cite your sources...

Sorry i didn't understand how put the code in a project. I must put in a different class? I must put a Receive, Service? Thank you so much!

Awesome, this satisfies The app called finish() on an activity very recently.

Also,
Runtime.getRuntime().exit(0) can be replaced with kotlin.system.exitProcess(0)

Finally! It helped me to delete database and recreate with default data. Thanks.

I can't get it work, sorry

package com.mycompany.myapp.util

import android.app.Activity
import android.content.Intent
import com.mycompany.myapp.ui.MainActivity

fun triggerRestart(context: Activity) {
    val intent = Intent(context, MainActivity::class.java).apply {
        addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    }
    context.startActivity(intent)
    context.finish()
    kotlin.system.exitProcess(0)
}

@russellhoff how about to replace kotlin.system.exitProcess(0) with Runtime.getRuntime().exit(0)?

already tried but with no success

Try to explain what is not working. It works on Andoid SDK 31, called from the main thread.
