代码一:理解从JDK23升级到JDK27后的警告和JDK27
提问于 2018-10-19 20:58:17
2018年5月，代号One被移至Android 27级。以前，我在商店中加载了一个用代码名一个构建的应用程序的0.1版本，该应用程序带有Android级别23 (这是以前的默认设置)。
谷歌迫使所有开发者在2018年11月1日前将应用程序升级到更新的API，这就是为什么我几天前向商店提交了同一个应用程序，没有任何代码修改，它是用最后一个版本的代号之一构建的。
今天我收到了以下的坠机保护报告。我的问题是帮助理解所有的警告和java.lang.SecurityException. 我的应用程序不需要任何特殊权限，在运行过程中也不要向用户询问权限(这是一个非常简单的应用程序)。在将应用程序升级到API级别27之前，我从来没有收到过这些警告和这个异常。

这似乎是华为发射装置上的一个漏洞。当用户按下应用程序主表单中的后退按钮时，默认情况下我们会最小化应用程序(正如Android中的惯例)。最小化方法是这样在Android上实现的：
public boolean minimizeApplication() {
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startMain.putExtra("WaitForResult", Boolean.FALSE);
getContext().startActivity(startMain);
return true;
}这实质上要求系统“回家”。它不需要权限或任何具体的东西，但华为似乎错误地配置了他们的活动，这是失败的。我认为这只是意味着在这些设备上退出应用程序将失败。用户可能仍然可以使用home按钮本身而不是后退按钮。
不幸的是，华为似乎没有公开的bug报告系统。希望他们能解决这个问题，否则就会有解决办法。
