The project uses Gradle 4.6 which is incompatible with Java 11 or newer.

Possible solution:
 - Upgrade Gradle wrapper to 7.2 version and re-import the project


// 解决办法：settings搜索gradle，修改gradle sdk版本为1.8

No version of NDK matched the requested version 20.0.5594570. Versions available locally: 23.1.7779620, 25.1.8937393, 25.2.9519653, 26.1.10909125

// 解决办法：local.properties添加：
ndk.dir=D\:\\NDK\\android-ndk-r19c


// 新版本在gradle里配置：
android {
    ndkVersion = "19.2.5345600" //"major.minor.build"
}

API 'variant.getMergeAssets()' is obsolete and has been replaced with 'variant.getMergeAssetsProvider()'.

// 解决办法：修改build.gradle，将：

variant.mergeAssets.doLast {
}
    
// 修改为：
    
variant.mergeAssetsProvider.get().doLast {
}

This app only has 32-bit [armeabi-v7a] native libraries. Beginning August 1, 2019 Google Play store requires that all apps that include native libraries must provide 64-bit versions. For more information, visit https://g.co/64-bit-requirement
