Hi All,
I am using B4A v8.80, FirebaseStorage library v1.11. About a month ago, I wrote program to use Firebase Storage with these versions and it worked fine.
About a week ago, I updated SDKs using B4A SDK manager with Recommended items. I have followed the new steps mentioned in https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/ and updated the Manifest editor.
Now, whenever the program reaches the code below, it crashes.
I am getting the error as shown below:
I changed back the Manifest Editor codes with the old snippets and still I am getting the same error.
All my Firebase storage related project are giving me the same error as shown above.
Below is my code in Activity Main:
Below is the code in Starter service:
The Manifest editor:
I checked CheckForGooglePlayServices() function, and it is returning True.
I have Firebase rules as follows:
Can you please help?
