why the launcher show app icos is larger then the native launcher( build on android 4.2.2 source)

I compiled and build the launcher on the android 4.2.2 source code.

and I installed it on my Nexus 4,I found there's some differences between them.

I saw the code of Launcher and find it override onCreateOptionsMenu() ,but the native launcher dont have the menu in launcher.

I add a shortcut on the launcher I build .the ico is larger then native.

and the native app is mucher more efficient than I build.

so I Have some question .

  • Is the open source code the same as the native app build source code ?

  • Why the shortcut ico in "my launcher" is larger?

  • The native launcher is more efficient,Why?

Solution

  • Add:

    <uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="17" />

    To your manifest file. It is missing by default and causes the launcher to run in some sort of compatibility mode, which makes the icons enlarged.
