How to launch android app with emulator and android device

i am facing problem with running on emulator and android device, i have created the emulator and connected with phone as well .

in Manifest file mainActivity if i give

   <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

its connecting to the phone and app runs success, but in emulator not running,

if i change category like below code its working with launching with emulator and not working launching on phone .

<category android:name="android.intent.category.DEFAULT" />

Could any one tell me what is the best intent-filter i have to give to run both emulator and phone.
