Error message

This plugin must be applied after "com.android.library" plugin

What it means

WeChatArmeabiCompat.gradle is a helper Gradle script that rewrites armeabi-v7a native libs to armeabi; it requires the Android library plugin to already be applied. It throws a GradleException at script-apply time if plugins.hasPlugin('com.android.library') is false.

Solutions

1. Apply the script only in modules that use 'com.android.library'
2. Ensure 'apply plugin: com.android.library' comes BEFORE 'apply from: WeChatArmeabiCompat.gradle' in the same script
3. Remove the script from application modules; adapt it (libraryVariants -> applicationVariants) if needed for apps

Example fix

// before
apply from: 'WeChatArmeabiCompat.gradle'
apply plugin: 'com.android.library'
// after
apply plugin: 'com.android.library'
apply from: 'WeChatArmeabiCompat.gradle'

// build.gradle
assert plugins.hasPlugin('com.android.library') : 'WeChatArmeabiCompat requires library plugin'

When it happens

Trigger: Applying the script in a com.android.application module, in a pure Java/Kotlin module, or applying it before 'com.android.library' in the plugin declaration order of the same build script.

Common situations: Copy-pasting the script into an app module's build.gradle; applying via 'apply from:' before the library plugin is loaded; using it in a legacy project where the module uses the app plugin.
