如何减少 ACRA 中的堆栈跟踪？
How to reduce stack trace in ACRA?
我正在使用 ACRA 从 Android 应用发送崩溃报告，一切正常。除了堆栈跟踪是巨大的这一事实。例如，一份报告可以包含大约 30000 个字符，如下所示：

我能以某种方式减少 "STACK_TRACE" 字段中的消息吗？例如，我可以从堆栈跟踪中只发送几行起始行吗？
创建自定义 ReportSender（扩展其中一个默认项），并在发送前修改报告。
您可以使用 @ReportsCrashes.reportSenderFactoryClasses
注册自定义 ReportSender
我正在使用 ACRA 从 Android 应用发送崩溃报告，一切正常。除了堆栈跟踪是巨大的这一事实。例如，一份报告可以包含大约 30000 个字符，如下所示：

我能以某种方式减少 "STACK_TRACE" 字段中的消息吗？例如，我可以从堆栈跟踪中只发送几行起始行吗？
创建自定义 ReportSender（扩展其中一个默认项），并在发送前修改报告。
您可以使用 @ReportsCrashes.reportSenderFactoryClasses
ReportSender
