Logcat 没有显示我的华为 P9 手机的错误 [英] Logcat not showing errors from my Huawei P9 phone

问题描述

我使用的是 Android Studio 2.3，我的手机是华为 P9 Lite.我注意到我的 logcat 没有显示我手机中的错误.例如，如果我的代码会因为 NullPointerException 而崩溃，并且我在模拟器上运行它，我会在 logcat 中得到异常(字体颜色:红色)并弹出说 MyApplication 停止工作，但是如果我在手机上运行相同的代码，我只会得到崩溃弹出窗口，而在 logcat 中什么也没有.显示信息消息，但不显示错误.我需要做什么才能在 logcat 中显示手机中的错误消息?

I am using Android Studio 2.3 and my phone is Huawei P9 Lite. I noticed that my logcat does not show errors from my phone. For example if I have code that will crash because of NullPointerException and I run it on emulator I get exception in logcat (font color: red) and popup saying MyApplication stopped working, but if I run same that code on my phone, i just get crash popup and nothing in logcat. Info messages are displayed, but errors are not. What do I need to do in order to show error messages from my phone in logcat?
