Android Studio升级4.0后的编译问题
没事儿不要手贱更新！！！
1、修改build.gradle文件版本6.5.1后报错
Could not find com.android.tools.build:gradle
根据控制台显示找到maven路径：https://maven.google.com/web/index.html
查找相应版本修改为com.android.tools.build:gradle:4.2.0-alpha02，编译报错
* What went wrong:
A problem occurred evaluating project ':app'.
> java.lang.ExceptionInInitializerError (no error message)
2、修改flutter版本1.17.4后，报错
* What went wrong:
A problem occurred evaluating project ':app'.
> Could not initialize class org.jetbrains.kotlin.gradle.plugin.sources.DefaultKotlinSourceSetKt
3、修改kotlin版本ext.kotlin_version = '1.3.50'后报错
* What went wrong:
Execution failed for task ':app:mergeDebugAssets'.
> This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry.
The following AndroidX dependencies are detected: androidx.core:core:1.1.0, androidx.slidingpanelayout:slidingpanelayout:1.0.0, androidx.fragment:fragment:1.1.0, androidx.versionedparcelable:versionedparcelable:1.1.0, androidx.lifecycle:lifecycle-common-java8:2.2.0, androidx.customview:customview:1.0.0, androidx.swiperefreshlayout:swiperefreshlayout:1.0.0, androidx.interpolator:interpolator:1.0.0, androidx.loader:loader:1.0.0, androidx.activity:activity:1.0.0, androidx.drawerlayout:drawerlayout:1.0.0, androidx.collection:collection:1.1.0, androidx.viewpager:viewpager:1.0.0, androidx.localbroadcastmanager:localbroadcastmanager:1.0.0, androidx.arch.core:core-common:2.1.0, androidx.savedstate:savedstate:1.0.0, androidx.annotation:annotation:1.1.0, androidx.lifecycle:lifecycle-common:2.2.0, androidx.lifecycle:lifecycle-livedata:2.0.0, androidx.legacy:legacy-support-core-ui:1.0.0, androidx.lifecycle:lifecycle-viewmodel:2.1.0, androidx.lifecycle:lifecycle-livedata-core:2.0.0, androidx.arch.core:core-runtime:2.0.0, androidx.legacy:legacy-support-v4:1.0.0, androidx.media:media:1.0.0, androidx.legacy:legacy-support-core-utils:1.0.0, androidx.documentfile:documentfile:1.0.0, androidx.cursoradapter:cursoradapter:1.0.0, androidx.coordinatorlayout:coordinatorlayout:1.0.0, androidx.asynclayoutinflater:asynclayoutinflater:1.0.0, androidx.lifecycle:lifecycle-runtime:2.2.0, androidx.print:print:1.0.0
4、修改build.gradle增加属性
android.useAndroidX=true
android.enableJetifier=true
依然报错：
* What went wrong:
Execution failed for task ':app:stripDebugDebugSymbols'.
> No version of NDK matched the requested version 21.0.6113669. Versions available locally: 21.3.6528147
5、先在Android studio安装SDK Tools后，命令行安装对应的ndk
sdkmanager 'ndk;21.0.6113669'
重新编译后成功
