Android Question How to launch another app to run in parallel?

[RobertK]

When I launch one of my apps from another using the following code, the second app replaces the first. They have only one entry in the list of recent apps, which shows only the first app. The user cannot kill one app without killing the other and cannot switch between them.

Dim MyIntent As Intent
MyIntent.Initialize(MyIntent.ACTION_MAIN, "")
MyIntent.SetComponent("my.second.app/.main")
StartActivity(MyIntent)

However, when I launch Google Earth from my app using the following code, the two do run in parallel. They have separate entries in the list of recent apps. The user can kill Google Earth without killing my app and vice-versa. The user can switch freely between my app and Google Earth. This is the behavior I am looking for.

Dim MyIntent As Intent
MyIntent.Initialize(MyIntent.ACTION_VIEW, "")
MyIntent.SetType("application/vnd.google-earth.kml+xml")
StartActivity(MyIntent)

What is correct way to achieve the desired behaviour with two of my own apps?

Your 1st code is the correct, Try to add/replace myintent.setpackage before/with myintent.setcomponent

Thanks for your suggestion.

Sorry my question was not clear. What I most wanted to know was how to run the app I am launching as a completely independent task. It turns out that in order to do so I need to set the following flag: FLAG_ACTIVITY_NEW_TASK (https://developer.android.com/reference/android/content/Intent#FLAG_ACTIVITY_NEW_TASK).

Hope this helps others with the same question.

Thanks again and nest wishes for a happy New Year.

External Application Launch from another program

How would you go about launching an external application from a button in a Basic4android application, and return to your B4a app when you close the app that you just launched?

www.b4x.com

only do this:

  Try
    Dim Intent1 As Intent
    Dim pm As PackageManager
        'Intent1 = pm.GetApplicationIntent ("com.whatsapp.w4b")  'whastupo bussines    - 'com.whatsapp for normal whatsup
        Intent1 = pm.GetApplicationIntent ("packane.name.here")
    StartActivity (Intent1)
      Catch
      ToastMessageShow ("Failed to launch app!  Is it installed?", True)
  End Try

No more is neccesary
