Kotlin aar Android Library crash

Question

I am try to build aar library now for getting device information. It seems fine when I build library, but when I integrate my test app with my library i keep crash.

This is my crash log.

And this my library code.

fun event(eventName: String) {

        val osName = "Android"

        val connect: ConnectivityManager = Context.CONNECTIVITY_SERVICE
        val netStatue = connect.activeNetworkInfo.typeName
        val networkString = netStatue.toLowerCase()

        val wm: WindowManager = Context.WINDOW_SERVICE
        val rotation = wm.defaultDisplay.rotation
        val sMode = when (rotation) {
            Surface.ROTATION_0 -> true
            Surface.ROTATION_180 -> true
            Surface.ROTATION_90 -> false
            Surface.ROTATION_270 -> false
            else -> null
        }

        val telephonyManager = Context.TELEPHONY_SERVICE
        val netwokrName = telephonyManager

        val app = PackageManager.GET_META_DATA as ApplicationInfo
        val bundle = app.metaData

        val packagename = app.packageName

    }

Can you tell me what am i missing?

Answer 1

The stacktrace doesn' t match the code you have posted.

The error message:

java.lang.String cannot be cast to android.net.ConnectivityManager

means that you have a String you are trying to cast as a ConnectivityManager.

Please be very careful you are getting the ConnectivityManager in the correct way.

According to the official guide here you should use:

val cm = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
