截断的 Logcat 异常消息

Question

我正在尝试调试一个 android 应用程序错误（在 AS2.1beta3 中），但 logcat 消息似乎被截断，它会为我提供有关导致问题的信息的信息。

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？这让我发疯了！

我不知道如何使错误消息完全显示在 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 并按 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。
