I have imported a project to Android Studio using Gradle. Import process was successful, but it gives an error for android.os.*, when I try to import it.
It is a libGDX project.
Recently, I met a similar case in Android Studio 3.2.1 Ubuntu/Linux version.
I am quite sure about the issue shall be related to the Android SDK installation,because I build the same project in Android Studio of my Windows 10 laptop.
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
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')
}
Install the correct android platform(correct API level as mentioned in the build.gradle file,if any) and rebuild the project.
