How to replace b4a pop-up animation when starting Activities

Question

In basic4android, when an Activity starts, it pops out from the corner of the screen on my phone.

I tried creating XML files for animations between Activities, but still Activities start with my animation along that annoying pop up animation.

I want to get rid of that and use my custom animation.

I'm using this function and two XML files to create an animation:

Sub ListView1_ItemClick (Position As Int, Value As Object)
    StartActivity(Value)
    SetAnimation("file1", "file2")
End Sub

Sub SetAnimation(InAnimation As String, OutAnimation As String)
    Dim r As Reflector
    Dim package As String
    Dim In, out As Int
   package = r.GetStaticField("anywheresoftware.b4a.BA", "packageName")
    In = r.GetStaticField(package & ".R$anim", InAnimation)
    out = r.GetStaticField(package & ".R$anim", OutAnimation)
    r.Target = r.GetActivity
    r.RunMethod4("overridePendingTransition", Array As Object(In, out), Array As String("java.lang.int", "java.lang.int"))
End Sub

and XML files

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="400"
        android:fromAlpha="0.0"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toAlpha="1.0" />

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
   android:duration="400"
        android:fromAlpha="1.0"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toAlpha="0.0" />

i'm using version 5.0.2 of b4a can this be the case?

This post from the b4x forums says you have to call SetAnimation right after either calling startActivity() or finish(). As your animation seems to work I guess you're not calling it immediately after calling one of these methods, so the default animation is still applied.

Okay sorry for that, I can't comment yet since I lack reputation so I had to write it as an answer. – Paul M. Aug 05 '15 at 17:59
