推荐答案

最近，我在Android Studio 3.2.1 Ubuntu/Linux版本中遇到了类似情况.

Recently, I met a similar case in Android Studio 3.2.1 Ubuntu/Linux version.

我非常确定该问题与Android SDK的安装有关，因为我在Windows 10笔记本电脑的Android Studio中构建了相同的项目.

问题: Android Studio中的Java编译器错误

Issue: Java compiler error at Android studio

error: package android.os does not exist
error: package android.media does not exist
error: package android.content does not exist
error: package android.util does not exist
error: cannot find symbol variable Log
error: cannot find symbol class Context
error: cannot find symbol class AudioRecord

解决方案: 在build.gradle文件中提到的android.jar未安装在/sdk/platforms/目录中.请参阅下面我的build.gradle文件中的android.jar依赖项(这引起了问题)，

Solution: The android.jar which was mentioned at the build.gradle file was not installed at the /sdk/platforms/ directory. See the android.jar dependency at my build.gradle file below(which caused the issue),

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile files(sdkDir+'/platforms/android-24/android.jar')
}

安装正确的android平台(如果有build.gradle文件，请参阅正确的API级别)并重建项目.

Install the correct android platform(correct API level as mentioned in the build.gradle file,if any) and rebuild the project.
