SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

问题描述:

已经安装了android-sdk 和gradle环境,并配置了环境变量,如下所示:

android环境

root@wangju-HP--G4:/home/wangju/Desktop/5i5j_android/AppFrameWork# adb version
Android Debug Bridge version 1.0.
Version 29.0.-
Installed as /usr/local/android-home/android-sdk-linux/platform-tools/adb

gradle环境:

root@wangju-HP--G4:/home/wangju/Desktop/5i5j_android/AppFrameWork# gradle -version

------------------------------------------------------------
Gradle 4.6
------------------------------------------------------------

Build time:   -- :: UTC
Revision:     8fa6ce7945b640e6168488e4417f9bb96e4ab46c

Groovy:       2.4.
Ant:          Apache Ant(TM) version 1.9. compiled on February
JVM:          1.8.0_211 (Oracle Corporation 25.211-b12)
OS:           Linux 4.15.--generic amd64

在android项目的app目录下执行gradle clean/tasks命令时会报如下错误:

* What went wrong:
A problem occurred configuring project ':app'.
> Failed to notify project evaluation listener.
   > SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
   > Must apply 'com.android.application' first!

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

解决办法:

根据错误提示

 SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

翻译过来的意思就是:没有找到sdk,可以在local.properties这个文件中定义android_home,即指明android sdk的所在位置

在app目录下新建local.properties文件,文件内容如下所示:

/usr/local/android-home/android-sdk-linux 是我android sdk的安装目录

sdk.dir=/usr/local/android-home/android-sdk-linux

配置好后,再用gradle clean即可
