注解掉了：com.android.settings和com.android.browser

有效果！

launcher:title，图标下面的文字，目前只支持引用，不能直接书写字符串。
 
launcher:icon，图标引用。
 
launcher:uri，链接地址。
 
launcher:packageName，应用程序的包名。
 
launcher:className，应用程序的启动类名。
 
launcher:screen，图标所在的屏幕编号。
 
launcher:x，图标在横向排列上的序号。
 
launcher:y，图标在纵向排列上的序号。

2.APK源码

\packages\apps\Browser\AndroidManifest.xml
 
            <!-- We are also the main entry point of the browser. -->
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.DEFAULT" />
           -     <category android:name="android.intent.category.LAUNCHER" />
           +     <!-- category android:name="android.intent.category.LAUNCHER" /-->
                <category android:name="android.intent.category.BROWSABLE" />
                <category android:name="android.intent.category.APP_BROWSER" />
            </intent-filter>

注解掉                <category android:name="android.intent.category.LAUNCHER" />

因为Launcher是根据应用清单文件里，可以作为参考。

3.无源码launcher内改

\packages\apps\Launcher3\src\com\android\launcher3\LauncherModel.java
 
for (int i = 0; i < apps.size(); i++) {
    LauncherActivityInfoCompat app = apps.get(i);
+    if("com.android.browser".equals(apps.get(i).getApplicationInfo().packageName)){
+        continue;
+    }
    mBgAllAppsList.add(new AppInfo(mContext, app, user, mIconCache, mLabelCache));
}

过滤掉com.android.browser包，仅做参考launcher3修改，launcher2并无找到对呀位置。
