@nya-elimuai Just added a new commit. fixed the test case so you can build the project. also, I tested the sign-in process using TrustWallet and AlphaWallet (as they support web3 & WalletConnect). but Metamask doesn't seem to work completely, could be a problem with Metamask or the WalletConnect library I used. I forked the library If that's the problem I'll try to find a fix for that.

@hhio618 Thanks. Updated, and tried again. The compilation is still not working for me:

./gradlew clean build

> Task :app:lintDebug FAILED
Lint found 1 errors, 135 warnings. First failure:

../SignInWithWeb3Activity.java: Error: The lint detector
    timber.lint.WrongTimberUsageDetector

The full lint text report is located at:
../crowdsource/app/build/intermediates/lint_intermediate_text_report/debug/lint-results-debug.txt

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:lintDebug'.
> Lint found errors in the project; aborting build.
  
  Fix the issues identified by lint, or create a baseline to see only new errors:
  android {
      lint {
          baseline = file("lint-baseline.xml")
      }
  }

@nya-elimuai fixed.

@nya-elimuai tested using Alphawallet! also, looks like trust wallet doesn't support Unicode chars in the input message(the thumbs up emoji)!

@hhio618 I downloaded the latest version of the branch, and code is not compiling for me:

./gradlew clean build

Does it work on your machine?

@nya-elimuai fixed, as I used android studio run tools didn't see that :D

@hhio618 I updated the code and tried again locally, but compilation still fails: https://github.com/elimu-ai/crowdsource/runs/6648804215?check_suite_focus=true

You can see the command used for compilation at https://github.com/elimu-ai/crowdsource/blob/main/README.md#development- and in the GitHub Action: https://github.com/elimu-ai/crowdsource/blob/main/.github/workflows/ci_pr.yml#L18

@nya-elimuai Although I couldn't reproduce it locally (for me it happens only on the CI pipeline), I updated the Timber Library back to 5.0.1 now works fine!

Thank you, @hhio618! 🙌🏽

I was now able to compile the code and launch it on a device. Question: What will happen if the user does not have any Web3 wallet app installed on their device? I haven't tested scenario yet.

@nya-elimuai you're welcome!

Question: What will happen if the user does not have any Web3 wallet app installed on their device?

How about notifying/redirecting the user to install a web3 wallet?

@hhio618 Yes, I think that would make sense, because that way it would work similarly as in our webapp. If no Web3 wallet app is found, perhaps we could redirect the user to MetaMask's Google Play page? https://play.google.com/store/apps/details?id=io.metamask

Here is the error message I'm getting on an Android emulator (no Web3 wallet app installed):
