Android application crashes on start, without loading the KoinModule

[tamasszadvari]

Using the latest version of the WorkspaceOne.Forms package (2.1.0) the app crashes instantly, when I start the application. It produces the following stacktrace:

If I call the KoinModule.Instance.Load(this); method in the Application class's OnCreate method, before the AWSDKDelegate.OnCreate(this); line, the app starts correctly.

The problem was present with the previous WorkspaceOne.Forms version too.

Please correct the setup instructions, or tell me what have I done wrong. Thanks!

Will check and confirm, are you able to build the sample app and run it?

[akalghatgi]

@tamasszadvari I guess you are explicitly invoking AWSDKDelegate.OnCreate(this); which is not required.

Please checkWorkspaceOneApplication.cs where you need to extend your Application Class with WorkspaceOneApplication and override the OnCreate(), this will take care on KoinModule Loading.

[tamasszadvari]

Hello @akalghatgi Yes, I'm invoking that method, because it's in the readme file. :) @Maddy79 I haven't tried. But I've done everything according to the instructions, so if it's true that I shouldn't invoke the AWSDKDelegate.OnCreate(this) method, then it should be removed from the documentation.

[Maddy79]

@tamasszadvari , please remove AWSDKDelegate.OnCreate from your code, we will update the document. Thanks for bringing this up.

@Maddy79 Without that, my application now crashes instantly. It doesn't even show the splash screen. See stack trace:

@tamasszadvari can you confirm if you have added base.OnCreate(this);

 public override void OnCreate()
 {
            base.OnCreate(this);
 }

please refer WorkspaceOneApplication.cs

[tamasszadvari]

@akalghatgi Thanks, that helped! :)

[Maddy79]

thanks @tamasszadvari to confirm this.
