Android Question Problem when use FirebaseAuth

Juanet · Apr 10, 2023

Hi, i have a problem when try to use FirebaseAuth, these are the steps and errors:

1) Installed and using B4A Version 12.20 (64 bit)

2) Unpacked "commandlinetools-win-9123335_latest.zip" in "C:\Android"

3) Unpacked "resources_11_22.zip" in "C:\Android"

4) Using the project "FirebaseAuth" posted in : https://www.b4x.com/android/forum/threads/firebaseauth-authenticate-your-users.67875/

5) Followed the rules posted in: https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/

6) Added the "google-services.json" file to the B4A Project folder

Thats the project manifest file:

B4X:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="31"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:hardwareAccelerated, "true")
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.

CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)
CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile(Macro, FirebaseAuth.FirebaseAuth)
CreateResourceFromFile(Macro, FirebaseAnalytics.FirebaseAnalytics)

When build everything is fine, but when signin i have that's error:

On the other hand, in a new B4XPages project, when try to build with exactly the same configuration in the manifest file, i have this error:

I have no idea why this happens, if someone can help me I would appreciate it, thank you very much.

1. Create a new B4XPages project and add a reference to FirebaseAuth.
Don't do anything else.
Does it compile?

2. Check Tools - Paths Configuration. Make sure that the IDE is configured to use the updated SDK (android.jar).

In the end I have managed to make it work with the example you have posted in:
https://www.b4x.com/android/forum/threads/facebook-extends-firebaseauth-to-support-facebook.67954/

Only need to change project name and put the "google-services.json" in the folder to work as expected.

I will try to try with B4X but at least for the moment It's okay for me already as it works

Thank you very much anyway Erel, It is appreciated.

Finally I have created a new project in B4XPages with FirebaseAuth, the problem with errors came from the PndExoPlayer library that in the end I have replaced with ExoPlayer and everything works normally.

B4XPages error when use PndExoPlayer:

B4X:

Error in C:\Android\tools\..\extras\b4a_local\unpacked-pnd-guava-31.1-android-63805534196160\dex_v1\pnd-guava-31.1-android.zip:classes.dex: ....

No errors if not use FirebaseAuth when use PndExoPlayer

No errors if use FirebaseAuth when use ExoPlayer

Conclusion, use ExoPlayer if you use FirebaseAuth.

I just wanted to put it on the record in case someone else happens.
