升級Android Studio之後舊專案"No toolchains found in the NDK toolchains folder for ABI"

升級Android Studio 3.2.1之後舊專案沒有用到NDK也會跑出
"No toolchains found in the NDK toolchains folder for ABI..."

網路上有很多解法，比較前面都是要你去下載舊版的NDK完整包，再改Project的NDK路徑過去，但是我專案都沒用到NDK幹嘛載回來改路徑??

另一種是改project的build.gradle，只要將gradle版本改成新版(和AS版本對應)就沒事了
AS 3.2.1用
        classpath 'com.android.tools.build:gradle:3.2.1'
AS 3.3用
        classpath 'com.android.tools.build:gradle:3.3.0'

另外因為gradle tool升級所以gradle版本也要升級，所以打開gradle\wrapper\gradle-wrapper.properties修改distributionUrl

AS 3.2.1用gradle tool版本4.6
        distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
AS 3.3使用gradle tool版本是4.10.1
        distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip


在build-tools比較後面的版本會順便寫建議修改內容
ERROR: No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android
This version of the NDK may be incompatible with the Android Gradle plugin version 3.0 or older.
