在package/apps/Launcher3/src/com/android/launcher3/LauncherModel.java中的private void loadAllApps() {}函数中的mBgAllAppsList.reorderApplist();之前添加如下：
// ZJ Add START
mBgAllAppsList.removePackage("com.mediatek.filemanager");
mBgAllAppsList.removePackage("com.android.chrome");
mBgAllAppsList.removePackage("com.android.providers.downloads.ui");
mBgAllAppsList.removePackage("com.android.deskclock");
mBgAllAppsList.removePackage("com.android.email");
mBgAllAppsList.removePackage("com.google.android.apps.maps");
mBgAllAppsList.removePackage("com.google.android.gm");
mBgAllAppsList.removePackage("com.android.soundrecorder");
mBgAllAppsList.removePackage("com.mediatek.FMRadio");
mBgAllAppsList.removePackage("com.google.android.inputmethod.korean");
// ZJ Add END
mBgAllAppsList.reorderApplist();
mBgAllAppList是类AllAppList的对象，可以看下AllAppList这个类的内容：
