[NavigationView] App crashes when using NavigationView in alpha8

Description: App crashes when inflating xml containing NavigationView. ‘Error inflating class com.google.android.material.navigation.NavigationView’

Expected behavior: No crash, unless I’m doing something wrong that should be done differently.

Android API version: 28

Material Library version: 1.1.0-alpha08 (works with alpha07)

Device: Emulator

[EdricChan03]

I’m facing a similar issue as well, but with BottomNavigationView.

I believe this can be fixed by setting the source/target compatibility Java version to 1.8 as the library updated the source/target compatibility version to 1.8 in 1.1.0-alpha08 (although one of the devs has commented that this will be reverted in 1.1.0-alpha09 - see #426):

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Note: The commit that updated the required Java version was 3280f6f (which was included in 1.1.0-alpha08) and the commit that will revert the required Java version to 1.7 is a628bf5.

Hope this helps!

Strange I was under the impression kotlin already uses java 1.8 by default. And I was already using java 8 features such as default methods for interfaces and lamda expressions. But I’m not sure what part of that was java and what part of that was kotlin magic… It works when setting the java version to 1.8.

It works down to Android 8 and since that’s the lowest Android version I’m planning to support (for now anyways). I’m just gonna keep it at 1.8, don’t see a reason to use 1.7 instead. NOTE that I’m not saying it does not work below Android 8, I simply didn’t even try that.

Thank’s for the help! 😃
