【问题】

在没有账户的时候，不应该有添加联系人群组的选项。

我们要把这个选项干掉。

【相关代码】

//PeopleActivity.java (packages\apps\contacts\src\com\android\contacts\activities)
1278 MenuItem addGroupMenu = menu.findItem(R.id.menu_add_group);

1483 private void createNewGroup()
1374 @Override
public boolean onOptionsItemSelected(MenuItem item)
定义有各个按键对应的动作
if (isSearchMode) addGroipMenu.setVisible(false);

1366 private void makeMenuItemVisible(Menu menu, int itemId, boolean visible)
选择可视按键

1265 @Override
public boolean onPrepareOptionsMenu(Menu menu)
在这里设置按键是否可视。主要观察addGroupMenu.setVisible()方法
1337 注释掉addGroupMenu.setVisible(true);
在这句之前已进行了一个判断，来确定addGroupMenu是否可视

注释掉这行后，功能按钮消失。

重启后，通讯录图标消失了
图标消失是因为出错。用fastboot重新烧录之后，通讯录正常。
修改源文件的错误，重新编译。push进去后，reboot，可以看到新打的log。
