[error]

Build Output

C:\Users\JS\AndroidStudioProjects\webviewtest1\app\src\main\AndroidManifest.xml:7:5-22:19: AAPT: error: attribute android:usesClearTextTraffic not found.

7라인은 <application 부터입니다...

Answer 1

gradle설정에서 compileSdkVersion과 buildToolsVersion이 23 미만인지 확인해보세요.

23이상으로 설정되어야 build error 나지 않습니다.

답변 감사합니다. 그런데 23 이상으로 설정되어 있습니다

    compileSdkVersion 28
    buildToolsVersion "29.0.2"

아... 자세히 보니 철자 대소문자가 틀렸네요.
usesClearTextTraffic -> usesCleartextTraffic 로 바꾸세요.

usesClear't'extTraffic

아 찾았습니다..
