Fatal Exception: java.lang.NoSuchMethodError

Question

I am dealing with that problem:

Fatal Exception: java.lang.NoSuchMethodError
No virtual method getActiveNetwork()Landroid/net/Network; in class Landroid/net/ConnectivityManager; or its super classes (declaration of 'android.net.ConnectivityManager' appears in /system/framework/framework.jar:classes2.dex)

There is my code:

 public boolean isNetworkAvailable() {

        ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

        if (connectivityManager != null) {


            if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
                NetworkCapabilities capabilities = connectivityManager.getNetworkCapabilities(connectivityManager.getActiveNetwork());
                if (capabilities != null) {
                    if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) {

                        return true;
                    } else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) {

                        return true;
                    } else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET)) {

                        return true;
                    }
                }
            }
        }

    return false;}

there is the stacktrace:

Fatal Exception: java.lang.NoSuchMethodError: No virtual method getActiveNetwork()Landroid/net/Network; in class Landroid/net/ConnectivityManager; or its super classes (declaration of 'android.net.ConnectivityManager' appears in /system/framework/framework.jar:classes2.dex)

does someone know how that can be fixed?

Please add the complete stack trace.

This Error occurs often when you have compiled with one version of your dependency but are running the code with a different version.

Here, it looks that com.olgazelenko.esofer.MainMenu.isNetworkAvailable(MainMenu.java:307) calls a method from android which is not found during your execution.

This method, getActiveNetwork, seemed to be added in Android SDK API Level 23. You maybe try to use it in a older version. see https://developer.android.com/reference/android/net/ConnectivityManager#getActiveNetwork(). Try to upgrade your minSdkVersion : https://developer.android.com/guide/topics/manifest/uses-sdk-element
