i'm trying to get Serial Number in android
in this answer Thaussma said that

in Android 8 and later (>= SDK 26) use android.os.Build.getSerial() which requires the dangerous permission READ_PHONE_STATE. Using android.os.Build.SERIAL returns android.os.Build.UNKNOWN.

but when i tried android.os.Build.getSerial() with required permission i got cannot resolve method 'getSerial()' error

What do you have in `compileSdkVersion` in your `build.gradle`? – m0skit0 Feb 11 '19 at 10:58
oh that's the mistake , i think i have to use version 28 ... i'm using version 25 – hassan moradnezhad Feb 11 '19 at 11:18

You said it in your question: "in Android 8 and later (>= SDK 26)". You have to use 26 or higher. – m0skit0 Feb 11 '19 at 11:19
@m0skit0 yes that's the answer ... thanks – hassan moradnezhad Feb 11 '19 at 11:20
