My android application name is three words long, but when I put it in phone it becomes two words long. How to solve this? I saw many application with three words example: \"
It doesn't matter what's on your screen; Google sets the rules. The limit is 50 characters.

A short app name for display on the device menu (12 character max including spaces between ) and a longer name for the App Store or Android Market (30 character max, recommend 20 including spaces between).
The max length a name displayed under an icon in either the home screen or apps list will depend on device and user settings. The name in the Settings->Manager Applications list will usually be longer, but again depends on certain factors.
Ok, I found out how a different app name displayed in PlayStore compared to the app name in app drawer on phone can be achieved:
The app name in PlayStore is defined in the developer console webpage of the app at parameter
Title = "This is my long app name"
The app name at the phone (e.g. app drawer) is defined in the Manifest of the app and here at the definition of the main activity:
<activity android:name="demo.MyActivity" android:label="ShortAppName">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>
It does not become two word long as you say but gets wrapped around and possibly get clipped. There is no limit per-se on the application name size however beyond a certain length it would ellipsize on the device.
For Instance, app name "Thisismybigname" wil show as "Thisismyb.." while "This is my big name" might show as "This is "
