问题
I just upgraded my cordova and ionic (npm upgrade -g cordova ionic) and now when I run "ionic cordova run --emulator" I'm getting the following error message:
Exception in thread "main" java.lang.NoSuchMethodError: com.android.prefs.AndroidLocation.getAvdFolder()Ljava/lang/String;
The build is successful, it just doesn't seem to want to start the emulator.
Any help would be very appreciated.
Here is the end of the log after the successful build message:
BUILD SUCCESSFUL

As it turns out, I just used Android Studio to update the SDK tools. Go to Preferences -> Appearance & Behavior -> System Settings -> Android SDK, then click the SDK Tools tab. I updated the following packages:
- Android SDK Build-Tools
- Android Emulator
- Android SDK Platform-Tools
- Android SDK Tools
- Intel x86 Emulator Accelerator
- Support Repository->Android Support Repository
- Support Repository->Google Repository
I'm honestly not sure which package solved my problem but I imagine updating all of them at the same time was a good idea. Hope this helps someone.
