I have a problem with an application when I tried to change the device's font (Samsung Galaxy Tab3), that being that my application crashes. In this case, the application is running in the background when I make the font change.

Steps:

  • Launch the app
  • Open device settings using status bar
  • Change device's font style
  • Return to the app using recent apps
  • Crash

I tried to test this scenario on other devices and can't reproduce it. My app crashed only on the Samsung device and only when the system font style changes.

Attached the log crash:

Stock Android 没有change device's font style

它一定是三星 TouchWiz 的东西。可能是，您应该查看三星特定的 SDK。

但如果我是你，我会通过广播接收器监听字体样式的变化。使用 Google Play 中的 Broadcast Monitor 应用程序找出要收听的广播。

然后，我会吞下空指针异常，并在发生这种情况时重新启动 Activity。我意识到这是一个激烈的动作，但是在您找出字体样式如何导致空指针异常之前，这可能是唯一的解决方法。
