Answer 1

  val mainIntent = Intent(Intent.ACTION_MAIN, null)
    mainIntent.addCategory(Intent.CATEGORY_LAUNCHER)
    val pkgAppsList = context.packageManager.queryIntentActivities(mainIntent, 0)

Answer 2

Using the below snippet you can get details of the installed app on a device

val packages: List<ApplicationInfo> =
    pm.getInstalledApplications(PackageManager.GET_META_DATA)

for (packageInfo in packages) {
    Log.d(
       "log",
        "Installed package :" + packageInfo.packageName
    )
    Log.d("log", "Source dir : " + packageInfo.sourceDir)
    Log.d(
       "log",
        "Launch Activity :" + pm.getLaunchIntentForPackage(packageInfo.packageName)
    )
}

This is already answered the question here in java. I just convert that into kotlin in IDE

Code->Convert java file to Kotlin

It works fine

You can do something like this:

val packages = packageManager.getInstalledApplications(PackageManager.GET_META_DATA)

for (packageInfo in packages) {
    Log.d(TAG, "Package name:" + packageInfo.packageName)
}
