I alread tried your sample from this link: https://www.b4x.com/android/forum/threads/version-safe-apk-installation.87667/#content

And adding

Code:

#Extends: android.support.v7.app.AppCompatActivity

at the top of code gives me the same error.

 

Here is the error after

Code:

I cannot upload the whole project for the some security reasons. Maybe i can just post here some parts of the code.

 

Here is the header of Main Activity

Code:

#Region  Project Attributes
    #ApplicationLabel: My App
    #VersionCode: 1
    #VersionName: 1.9.0
    #SupportedOrientations: portrait
    #CanInstallToExternalStorage: False
    #IgnoreWarnings: 32
    #BridgeLogger: True
#End Region

#Extends: android.support.v7.app.AppCompatActivity
#AdditionalRes: ../Res
#AdditionalRes: ../res.SweetAlertDialog
#AdditionalRes: ../res.MaterialIshProgress
#AdditionalJar: com.android.support:support-v4
#AdditionalJar: com.google.android.gms:play-services-location

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: False
#End Region

 

Here is the list of libraries i used

 

Hi Erel thanks for you help. I already fix it, but i not sure what happen. For the benefits of the others for this post, I tried to comment #AdditionalResources one by one then run it. Then I remove all the codes from Activity Create and it runs successfully. After that, I tried to uncomment the codes from #AdditionalResources then run it. Lastly I bring back the codes from the Activity Create and successfully it runs. Maybe it its IDE's bug but I not sure. Once again thank you for your fully support.
