Description

### What is this about?

Having poured over the setup instructions and sought help on Discord, I've hit a road block in my attempt to setup `metamask-mobile` for local development on Ubuntu 24.

Whenever I execute `yarn start:android`, I receive the following error:

```
FAILURE: Build failed with an exception.

* Where:
Build file '/home/daniel/AndroidStudioProjects/metamask-mobile/node_modules/react-native-aes-crypto-forked/android/build.gradle' line: 22

* What went wrong:
A problem occurred evaluating project ':react-native-aes-crypto-forked'.
> Could not find method compile() for arguments [com.android.support:appcompat-v7:23.0.1] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.
```

In preparing for to submit this issue, I rebooted to start from scratch. Though I suspect the issue described above is still pertinent, now I see:

```
> Task :app:createBundleProdDebugJsAndAssets
warning: Bundler cache is empty, rebuilding (this may take a minute)
SyntaxError: index.js: Invalid METAMASK_BUILD_TYPE of was passed to metro transform
Error: Invalid METAMASK_BUILD_TYPE of was passed to metro transform
```

According to the script output, that variable is set to this:

```
METAMASK_BUILD_TYPE is set to: main
METAMASK_ENVIRONMENT is set to: local
```

Hopefully this is helpful. I'm glad to provide more details, as I'm eager to get this up and running.

Research direction

Reproduce the setup with `yarn start:android`, then inspect `node_modules/react-native-aes-crypto-forked/android/build.gradle` at line 22 and the `index.js` Metro error involving `METAMASK_BUILD_TYPE`. Compare both failures with the reported environment values; done means the local Android development build completes without either error.
