I could probably pay for the lib...Because i need to study the creation process too.I tried two days for creating a wrapper,writing inline java with javaobject to implement this library but failed.So am requesting any one to make it.Its some want needed lib for many who needs to login their app by ease.
Yes i made the same of you a time ago, but my client dont like this.
In my case i needed facebook + google login.
Result = i lost one client and a big app in b4a is changed to Android Studio with other programmer.
Anyway I'm glad you solve your problem
Maybe one day, no one else need to open these same topics again.
Please find below attached files with lib and sample.
To use the sample you need to register application in Google Developer console.
Create Google API Credentials: OAuth2 Client ID, Application type: Android,
Signing-certificate fingerprint: SHA-1 (You will find it in Tools->Private Sgn Key->Signature (read-only): Certificate fingerprints: SHA-1: **:**:...)
Package name: b4a.signin
Please test and tell me the results. I will later register a separate thread for the library.
After authorization we have to click ones more to get detail (I think thats the issue with msgbox)
For multiple accounts we cant select them that is another issue (multiple user names was shown in msgbox but authorization popup only comes from the last one)
in effect library works with out webview or entering details...awesome work
