我需要摆脱 Android 4.1 平板电脑上的系统栏，因为平板电脑将处于商业/零售环境并用于商业用途。我的应用程序将是平板电脑上唯一使用的应用程序，它需要尽可能多的屏幕空间来完成我们正在尝试做的事情。我已经搜索过了，我发现有办法在有根的平板电脑上做到这一点，但是由于这将在一个企业中部署到数百或数千个企业，我不能让所有的平板电脑都植根于法律和安全问题。（如果我要根植它们，我真的会在法律上遇到问题吗？）
我知道您可以使状态栏变暗并使按钮成为圆点，但这确实不是最佳选择。
如果没有办法摆脱它，是否可以更改状态栏图标和功能？我问这个是因为我们的应用程序顶部有一个状态栏，我们可以将其移动到底部并更改状态栏的图标和功能以匹配应用程序的状态栏，因此不会丢失屏幕空间。
我读过 4.2 为应用程序添加了一些全屏功能。这是真的？状态栏可以隐藏在 4.2 中而不是 4.1 中吗？
I need to get rid of the system bar on Android 4.1 tablets
That is not possible, except via rooted devices and/or ROM mods. Moreover, the user needs this bar to be there, otherwise they have no access to the HOME and BACK buttons.
Would I really have issues legally though if I were to root them?
StackOverflow is not a law office. Please consult with qualified legal counsel regarding such concerns.
is it possible to change the status bar icons and functionality?
That is not possible, except via rooted devices and/or ROM mods.
I have read that 4.2 adds some fullscreen functionality for apps. Is this true?
Not exactly. The bottom navigation bar (HOME, BACK, RECENTS) can be hidden, but they will return as soon as the user touches the screen. The top status bar (signal strength, battery level, etc.) can be removed via a Fullscreen theme.
