Populatewallpapertypes () method in Wallpapertypesettings.java

Altogether found 4 packages to set wallpaper
com.android.launcher--Wallpaper Options
com.cyanogenmod.trebuchet--wallpapers, including photos and live wallpaper, etc.
com.android.gallery3d--Gallery
com.android.wallpaper.livepicker--Live Wallpaper

Here, I selectively do not load com.android.launcher
The Modified code:

if (!info.activityinfo.packagename.equals ("Com.android.launcher"  )) {   Parent.addpreference (pref);} // Fix Bug End

Last effect, select the wallpaper source interface with only 3 options

/**-------------------------------Appendix-------------------------------*/

Wallpaper_chooser.xml (Packages\apps\launcher2\res\layout)
Sets the page when the wallpaper is set. Above is the wallpaper, below is a set button.
