### What did you do?
<!–
If doable, present a recipe for reproducing the error.
A whole runnable program is sweet.
A hyperlink on play.golang.org is greatest.

Calling `web.InterfaceAddrs()` fails on Android app targetting SDK model 30. With `construct.gradle` trying like:
“`
android {
compileSdkVersion 30
buildToolsVersion “30.0.0”
defaultConfig {
applicationId “com.instance.testapp”
minSdkVersion 29
targetSdkVersion 30
versionCode 1
versionName “1.0”
testInstrumentationRunner “androidx.take a look at.runner.AndroidJUnitRunner”
}
buildTypes {
launch {
minifyEnabled false
proguardFiles getDefaultProguardFile(‘proguard-android-optimize.txt’), ‘proguard-rules.professional’
}
}
}
“`
Constructing the very same app targetting SDK 29 works, and returns no error:
“`
android {
compileSdkVersion 30
buildToolsVersion “30.0.0”
defaultConfig {
applicationId “com.instance.testapp”
minSdkVersion 29
targetSdkVersion 29
versionCode 1
versionName “1.0”
testInstrumentationRunner “androidx.take a look at.runner.AndroidJUnitRunner”
}
buildTypes {
launch {
minifyEnabled false
proguardFiles getDefaultProguardFile(‘proguard-android-optimize.txt’), ‘proguard-rules.professional’
}
}
}
“`
### What did you anticipate to see?
Targetting SDK 30 would behave no in a different way.
### What did you see as an alternative?
Calling `web.InterfaceAddrs()` leads to error `route ip+web: netlinkrib: permission denied` when embedded in Android app targetting SDK 30 (R):
