How to locate app crash logs in Android phone?
提问by user249605
If any Android app crashes some crash logs are generated on behalf of that app. How to find the location of such crash logs.
如果任何 Android 应用程序崩溃，则会代表该应用程序生成一些崩溃日志。如何找到此类崩溃日志的位置。
I want crash logs inside the Android device, not really using Logcat to see the crash logs.
我想要 Android 设备中的崩溃日志，而不是真正使用 Logcat 来查看崩溃日志。

You can use ACRA to see the stack trace when an app crashes on a device. It's a library and you can call its API wherever you want in your program. There are several choices for where to send the information, among them an email address. Here are the instructions for setting it up: https://github.com/ACRA/acra/wiki/BasicSetup
