Update app problem

[GaNdAlF89]

I update my app downloading the new apk from a personal server, not from Google Play, but during the update setup android asks me a confirmation to replace the existing app with the new version. There is any way to skip this step? I would like something as Google Play Store, which automatically runs the updates without user interaction. Thanks!

There is any way to skip this step?

No. This is a security feature which you cannot workaround. This is also the case when you install an app with B4A-Bridge.

Ok, therefore can I to capture the Cancel button (like cancel button of MsgBox2) pressed when Android ask confirmation to replace the existing app? For example, Android ask to replace the existing app, but the user press on Cancel...

There is no way to intercept this button. You can add an intent filter that listens to the "package replaced" intent: http://www.b4x.com/forum/basic4android-updates-questions/24720-update-app-autostart.html#post143131

I'm not sure what exactly you are trying to build, but it might be useful.

I post the code in which I have this problem. This is something like a launcher, that checks if there is a new apk (downloaded from the main app), and if true it installs this and then starts app. If false, it just starts app.

If File.Exists(File.DirRootExternal,"dir/dir/..../setup.apk") Then

    'if there is a new apk, installs it
            
    Dim iIntent As Intent 
    iIntent.Initialize(iIntent.ACTION_VIEW,"file:///sdcard/dir/dir/..../setup.apk")
    iIntent.SetType("application/vnd.android.package-archive")

    StartActivity(iIntent) 
    
    'I have to wait for user click on the setup confirmation - There are other solutions??
    Sleep(SetupInterval * DateTime.TicksPerSecond)
            
    Dim in As Intent
    in.Initialize(in.ACTION_MAIN, "")
    in.SetComponent("package_name")
    
    'Problem
    'if user clicks on Cancel, and then clicks on Android Settings button (in tray), this row is executed but it doesn't work!!   
    StartActivity(in)
            
Else 
    'if there isn't an update, it starts the app

    Dim in As Intent
    in.Initialize(in.ACTION_MAIN, "")
    in.SetComponent("package_name")
            
    StartActivity(in)
            
End If

Sleep function:

Sub Sleep(ticks As Int)

    DoEvents
   
    If ticks > 0 AND DateTime.TicksPerSecond > 0 Then
        Dim milliseconds As Int: milliseconds = 1000 / DateTime.TicksPerSecond * ticks
        Dim Lock1 As Lock
      
        Lock1.Initialize(True)
        Lock1.WaitFor(milliseconds)
        Lock1.Unlock
      
    End If
   
End Sub

There is no solution?

As I wrote before you should use PhoneEvents to listen to the PackageAdded event and then start the app. Such waiting loops or locks will not work.

Can you post an example code please?

Start with adding (and starting) a Service that uses PhoneEvents to listen to the PackageAdded event.
