MMKV does not correctly autolink

[mrousavy]

MMKV does not show up in the left side of Android Studio (dependencies), and can therefore not be imported (as shown in the installation step in the readme).

The current workaround for this is:

1. Add this to settings.gradle:

include ':react-native-mmkv'
project(':react-native-mmkv').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-mmkv/android/')

2. Add this to build.gradle (in app/), inside of dependencies (under implementation("com.facebook.react:react-native:+")):

  implementation project(':react-native-mmkv')

I am not sure what is missing from my configuration, but this will likely change soon when TurboModules will be released (maybe RN 0.65?), because I will rewrite the library - no extra installation steps will be needed then!

I also had to import com.facebook.react.bridge.JSIModulePackage; in MainApplication.java to make it work on android

I believe this works with v1.2.5 now, let me know if anyone can confirm

im using sir the latest version "react-native-mmkv": "^1.2.5",

[mrousavy]

This should work with 1.3.0 and above, so you can revert those two steps mentioned in my original comment. Let me know if you are still having issues autolinking MMKV.
