你好@tech_android 和@gulab 帕特尔。我已经找到了解决方案。
Android Gradle 允许您根据处理器(“armeabi-v7a”、“arm64-v8a”、“x86”和“x86_64”)拆分您的 apk。这样你最终会得到 4 个 apk 而不是一个，每个的大小将是第四部分，在 Google Play 中你上传所有四个 apk，当用户尝试下载你的应用时，Google Play 会选择正确的 apk取决于用户的设备处理器。
您必须以这种方式在 gradle 中设置应用拆分:
在 compilerOptions 节点下方(在 android json 节点内):

splits {
    // Configures multiple APKs based on ABI.
    abi {
        // Enables building multiple APKs per ABI.
        enable true
        // By default all ABIs are included, so use reset() and include to specify that we only
        // want APKs for x86 and x86_64.
        // Resets the list of ABIs that Gradle should create APKs for to none.
        reset()
        // Specifies a list of ABIs that Gradle should create APKs for.
        include "armeabi-v7a"
        include "arm64-v8a"
        include "x86"
        include "x86_64"
        // Specifies that we do not want to also generate a universal APK that includes all ABIs.
        universalApk false
    }
}

就在依赖节点之前:

// This next piece of code is used by apk Split
// map for the version code that gives each ABI a value. make sure to list all ABIs mentioned in splits block, an keep the order.
ext.versionCodes = ['armeabi-v7a': 1, 'arm64-v8a': 2, 'x86': 3, 'x86_64': 4]
