我在Crashlytics中有几个经常性的日志,我无法阅读。
java.lang.NullPointerException

java.lang.NullPointerException
at com.app.mobile.RutaActivity.a(SourceFile:747)
at ahh.run(SourceFile:1055)
at java.lang.Thread.run(Thread.java:856)
在第一个日志中,我的应用程序包的名称从未被提及,因此我甚至不知道在哪里寻找我的NPE。
在第二个日志中,我有FileName(RutaActivity)但是当我查看行号时,我看不到NPE错误的地方......
我该怎么办? 如何在第二个日志中查看方法名称而不是?

我联系Crashlytics支持,我解决了这个问题!
他们告诉我查看Crashlytics.log:
在Linux / Windows上: 〜/ .crashlytics / com.crashlytics.tools / crashlytics.log
在Mac上: 〜/库/缓存/ com.crashlytics / com.crashlytics.tools/crashlytics.log
我在这里看到了:
Crashlytics detected deobfuscation, but did not find a mapping file at /Users/admin/AndroidstudioProjects/MyApp/build/outputs/mapping/release/mapping.txt
所以我刚刚改变了
-printmapping mapping.txt
到
-printmapping build/outputs/mapping/release/mapping.txt
它有效!
Tx为你提供帮助!
答案 1 :(得分:4)
我在Proguard文件中为Crashlytics提供以下两行:
-keep class com.crashlytics.** { *; }
-keepattributes SourceFile,LineNumberTable
答案 2 :(得分:0)
要添加@Dharmendra提到的内容,在当前版本的Crashlytics中,their documentation说:
要让Fabric正确去除崩溃报告,您需要从配置文件中删除这一行,否则我们将无法自动上传您的映射文件:
-printmapping mapping.txt
此外,如果您在自己的Android库中包含父项目使用的代码,请确保在项目和库的proguard-rules.pro文件中删除它(这是我的问题)。
