Answer 1

I solved this issue.
I change my build.gradle file.
Before:
ext {
buildToolsVersion = "29.0.3"
minSdkVersion = 21
compileSdkVersion = 29
targetSdkVersion = 29
ndkVersion = "20.1.5948944"
}
After:
buildscript {
ext {
buildToolsVersion = "29.0.3"
minSdkVersion = 21
compileSdkVersion = 30
targetSdkVersion = 30
ndkVersion = "20.1.5948944"
}
