Android Question [Solved]How to get result from StartActivity(Intent)

opus · Nov 11, 2015

Hi,
I'm using the AppUdating library https://www.b4x.com/android/forum/threads/appupdating-automate-apps-updating-from-a-webserver.37783/
When the update is presented to the user, started by

B4X:

Dim i As Intent
  i.Initialize(i.ACTION_VIEW, "file://" & File.Combine(File.DirDefaultExternal, "tmp.apk"))
  i.SetType("application/vnd.android.package-archive")
  StartActivity(i)

I would like to get a feedback if the user cancled the installation of the new .apk.
Searching the Forum I found "StartActivityForResult", however I don't get how to incooperate it in here.

Al I need is a feedback into the original app, since if the user confirms the installation, the original app wil be killed in the process of updating.

This intent will not work with StartActivityForResult.

However you can use PhoneEvents to monitor the PackageAdded event. It will be raised if the installation was successful.

Thanks for the reply.
Using the Event "PackageAdded" will not solve problem, since this Event will only fire if the Installation was accepted. However, I'm looking just for the opposite.

If the event was not raised and Activity_Resume of your app was called then you know that the app was not installed.

Good Point, will look into that.

Looks like I got in working, using a Boolean which is set only if the Status from the apkUpdate tells me the user was asked o install (Checked in _UpdateComplete Event).
This Boolean is checked in the activity routine.
I'll look into more details after the weekend (busy with realworld stuff!)

I got it solved:
In the Activity_Resume Event I use:

B4X:

  If (UpdateTried=True) Then  'this Global Boolean is set to True in the _UpdateComplete Event.
       Dim Check As Int
       Check=Msgbox2(  MyResources.getapplicationString("UpdateTried"),MyResources.getapplicationString("UpdateTriedTitle"), MyResources.getapplicationString("UpdateTriedButtonFollowingUpdates"),"",MyResources.getapplicationString("UpdateTriedButtonCancelUpdates"),Null)
       If (Check=DialogResponse.negative)Then
         AutoUpdate=0 'Global Var holding the Setting for AutoUpdate
         StateManager.SetSetting("AutoUpdate",AutoUpdate)
         chbxAutoUpdate.Checked=False 'The OptionsView in which the AutoUpdate Setting can be set manualy
         StateManager.SaveSettings
       End If
       UpdateTried=False 'Reset the Boolean for further use.
   End If

and in the _UpdateComplete Event:

B4X:

Sub Updater_UpdateComplete
   Select apkupdt.Status
     Case apkupdt.OK_CURVER
       Log("Running apk version: " & apkupdt.CurVN)
     Case apkupdt.OK_WEBVER
       Log("Webserver apk version: " & apkupdt.WebVN)
       Log("Optional Change Log data: " & apkupdt.WebChangeLog)
     Case apkupdt.OK_NEWERAPK
       Log("Newer version available")
     Case apkupdt.NO_NEWERAPK
       Log("No newer version available")
     Case apkupdt.OK_DOWNLOAD
       Log("Newer version downloaded")
     Case apkupdt.OK_INSTALL
       Log("User asked to install newer version")
       UpdateTried=True
     Case Else
      Log("Status: "&apkupdt.Status)
   End Select
End Sub
