解决办法：File-->Project Structure--->SDK location--->JDK location was moved to Gradle Settings
然后将gradle jdk选择为和如下相同：
File-->Setting--->Build.Executiion,Deployment--->Gradle--->Gradle JDK(目前自己的为Android Studio Default JDK)

错误二：
List of apks:
[0] 'D:\Users\Desktop\openGL_Android_demo-master\BaseDemo\OpenGL_FBOBit\app\build\outputs\apk\debug\app-debug.apk'
Installation failed due to: 'Failed to commit install session 1908853544 with command cmd package install-commit 1908853544. Error: INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackageLI: /data/app/vmdl1908853544.tmp/base.apk (at Binary XML file line #27): com.example.opengl_fbobit.MainActivity: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present'
在activity中添加exported=true即可解决
