android - 截断的 Logcat 异常消息

Question

我正在尝试调试 Android 应用程序错误(在 AS2.1beta3 中)，但 logcat 消息似乎在它会给我有关导致问题的信息的位置处被截断。

错误信息:

Caused by: com.fasterxml

有时它会在末尾显示一个额外的句点，即com.fasterxml.

我该怎么做才能看到整个消息？这让我抓狂!

我不知道如何使错误消息看起来完全出现在 logcat 中，但我的方法是调试应用程序并在 com.firebase.client.FirebaseException 上启用异常断点>.

在 Android Studio 中打开菜单运行 -> 查看断点 -> 加号 -> 3. Java 异常断点 -> 粘贴 com.firebase.client.FirebaseException 然后按 OK。

现在，如果发生异常，应用程序将停止，您有时间查看异常，包括调试器中的完整堆栈跟踪。
