When calling Rho.Log.showLog(); in JavaScript I get the following error in Android (Device log in Android Monitor):

E/Web Console(5693): Uncaught Error: Error calling method on NPObject. at http://127.0.0.1:34254/public/api/rhoapi-modules.js:1

When tapping the "Log" menu item in the Android App menu I get the following application crash. My Android application menu is defined as:

    @default_menu = {
      "Log" => :log,
      :separator => nil,
      "Close" => :close
    }

I use RMS 5.0.25, minSDK 17, SDK 4.4.2, NDK 10d. Error happens on Android 4.2 and 4.4.

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.coursewalk.coursewalk/com.rhomobile.rhodes.ui.LogViewDialog}; have you declared this activity in your AndroidManifest.xml?
