android studio Android9（28）升级到Android10（29）Androidx小计

环境：Windows10，Android studio 3.6.2

1、参考Android官方推荐方式：https://developer.android.com/jetpack/androidx/migrate

2、由官方文档，第一步于gradle.properties文件添加

android.useAndroidX=true
android.enableJetifier=true

3、Android studio选择迁移到Androidx

Android studio会全局搜索不符合Androidx的导包等

替换前的依赖	替换后的Androidx依赖
`com.android.support:appcompat-v7:${version["androidSupportSdkVersion"]}`	`androidx.appcompat:appcompat:1.2.0`
`com.android.support:support-v4:${version["androidSupportSdkVersion"]}`	`androidx.legacy:legacy-support-v4:${version["androidXSdkVersion"]}`
`com.android.support:support-annotations:${version["androidSupportSdkVersion"]}`	`androidx.annotation:annotation:${version["androidXSdkVersion"]}`
`com.android.support:recyclerview-v7:${version["androidSupportSdkVersion"]}`	`androidx.recyclerview:recyclerview:${version["androidXSdkVersion"]}`
`com.android.support.constraint:constraint-layout:${version["constraintLayout"]}`	`androidx.constraintlayout:constraintlayout:2.0.2`
com.android.support:cardview-v7:${version["androidSupportSdkVersion"]} `com.android.support:recyclerview-v7:${version["androidSupportSdkVersion"]}`	`androidx.core:core-ktx:1.3.2`

配置文件：

ext {

    android = [
            compileSdkVersion: 29,
            buildToolsVersion: "29.0.3",
            minSdkVersion    : 21,
            targetSdkVersion : 29,
            versionCode      : VERSION_CODE as int,
            versionName      : APP_VERSION
    ]
    version = [
            androidSupportSdkVersion: "28.0.0",
            androidXSdkVersion      : "1.1.0",
            retrofitSdkVersion      : "2.2.0",
            butterknifeSdkVersion   : "8.8.1",
            constraintLayout        : "1.1.2",

            espressoSdkVersion      : "2.2.2",
            canarySdkVersion        : "1.5.1",
            dagger2SdkVersion       : "2.10",
            rxlifecycleSdkVersion   : "1.0",
            rxlifecycle2SdkVersion  : "2.0.1"

    ]


    dependencies = [
            //androidx
            "appcompat"                : "androidx.appcompat:appcompat:1.2.0",
            "core-ktx"                 : "androidx.core:core-ktx:1.3.2",
            "constraintlayout"         : "androidx.constraintlayout:constraintlayout:2.0.2",
            "legacy-support-v4"        : "androidx.legacy:legacy-support-v4:${version["androidXSdkVersion"]}",
            "annotationsX"             : "androidx.annotation:annotation:${version["androidXSdkVersion"]}",
            "recyclerview"             : "androidx.recyclerview:recyclerview:${version["androidXSdkVersion"]}",
            "designX"                  : "com.google.android.material:material:1.2.1",

            //support
            "appcompat-v7"             : "com.android.support:appcompat-v7:${version["androidSupportSdkVersion"]}",
            "exifinterface"            : "com.android.support:exifinterface:${version["androidSupportSdkVersion"]}",

            "design"                   : "com.android.support:design:${version["androidSupportSdkVersion"]}",
            "support-v4"               : "com.android.support:support-v4:${version["androidSupportSdkVersion"]}",
            "cardview-v7"              : "com.android.support:cardview-v7:${version["androidSupportSdkVersion"]}",
            "annotations"              : "com.android.support:support-annotations:${version["androidSupportSdkVersion"]}",
            "recyclerview-v7"          : "com.android.support:recyclerview-v7:${version["androidSupportSdkVersion"]}",
            "constraint-layout"        : "com.android.support.constraint:constraint-layout:${version["constraintLayout"]}",
...
    ]


}

使用：

implementation rootProject.ext.dependencies["appcompat"]

Ps:其中依赖：com.google.android.material:material:1.2.1 可能会报冲突错误：

error: duplicate value for resource 'attr/backgroundColor' with config '' com.google.android.material:material

解决办法用之前的依赖：com.android.support:design:${version["androidSupportSdkVersion"]}
