Android Studio AVD Emulator non-watch error - android

I am trying my hand at developing simple apps with the Android Studio and I cannot seem to run even the default app with a blank activity containing the string "Hello World". When I try and run a device on a running Emulator, it gives me an error message and says it the app is not compatible on a watch. I don't know why it would think the emulator is a watch, but I don't know why I cannot emulate an app without changing anything manifest on the simplest AVD provided. Here is an image of the compatibility http://imgur.com/DEWoaON

Having experienced these ClassCastExceptions before, I'd suggest that you check that you do not have a same id being shared by different widgets. Also, check with layouts in different layout-qualifiers folders for the same condition.

To see code of the activity you can checkout this gist https://gist.github.com/darthvish/873dc292c841e5c86312
As you are using some deprecated features, so it may not supported for some API levels. For this you can check the api level as well as version before using the deprecated features using if condition. For example :
if(Build.VERSION.RELEASE.equals("4.4.4")) {

So, thoughts?
I was also trying to implement it and got the same error .After lot of effort I was able to run it but received the similar error as you have received .
I resolved the issue by
1:Close and start your eclipse .
2: copying the v4 jar of main project in all the library projects and deleting the existing ones .
The error comes due to mismatch of supportv4jar. Make all the supportv4jar of same version
3:after that Delete the gen and bin folder and clean the project and run .

Dev Tools app on Android Emulator crashing on sdcard scanning?

So I open Dev Tools app to refresh emulator's sd card. The sd card has been re-created, is not read-only and I can create folders on it, move files, etc.
And when I click on "Scan SD Card" button
the app crashes.
Did anyone have issues like this on the Emulator? Emulator is running SDK 19 (4.4.2), it's x86 image with XXHDPI resolution.
I am running Android Studio 1.0 and AVD was created using Android Studio 0.8 or something.
It's odd that I cannot find similar issues on Internet, like it's happening to me only.
EDIT
Logcat Error I get is

Try running it from the 'ADB Command Prompt'
This command did the trick for me:
adb shell am broadcast -a android.intent.action.MEDIA_MOUNTED -d file:///mnt/sdcard/DCIM/100ANDRO/
Now, I can see images uploaded from the Android Device Monitor.

You're calling getResources() from a field initializer. Something like
private String mStr = getResources().getString(...);
(or with drawables or other kind of resources).
This is not valid, since the Context isn't set up yet. Move this assignment inside the onCreate() method.
The checked exception java.lang.NullPointerException is thrown when you're trying to use an object without reference,in simple words that means: you're trying to use a object variable without value.
Remember that a variable hold bits, primitive and non-primitive variable do, but the difference is that primitive variable hold the value in bits, but non-primitive variable hold the bits (like a direction) to access the object in memory, and when it's not being used anymore GGC (Garbage Colector) kills it.
