minifyEnabled true如果我使用 Proguard (和shrinkResources true) ,我的崩溃报告有点没用

这是 Proguard 的报告:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ProgressBar.setVisibility(int)' on a null object reference
    at xx.xxxx.xxx.xxxxx.xxxxxx.restoreViewAfterLoading(Unknown Source)
    at xx.xxxx.xxx.xxxxx.xxxxxx.newInstance(Unknown Source)
                                                     onCreateView
                                                     onViewCreated
                                                     access$000
    at xx.xxxx.xxx.xxxxx.xxxxxx$1.success(Unknown Source)
    at xx.xxxx.xxx.xxxxx.xxxxxx$1.success(Unknown Source)
    at retrofit.CallbackRunnable$1.run(Unknown Source)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698)

这是没有 Proguard 的正常报告:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ProgressBar.setVisibility(int)' on a null object reference
    at xx.xxxx.xxx.xxxxx.xxxxxx.restoreViewAfterLoading(xxxxxx.java:123)
    at xx.xxxx.xxx.xxxxx.xxxxxx.access$000(xxxxxx.java:26)

我可以做些什么来使用 Proguard 获取行号吗?

看起来您在某个文件中的某个文件中有一个 NPE,该方法称为restoreViewAfterLoadingwhere在某个文件的setVisibility第 123 行周围的 ProgressBar (为空)上调用。这一切都发生在改造回调上。所以我要解决的第一个想法是检查 null 以防用户完成此活动/片段。

要获得更好的行号,请将以下内容添加到您的 proguard 配置中

# Preserve annotations, line numbers, and source file names
-keepattributes *Annotation*,SourceFile,LineNumberTable

这将保留混淆堆栈跟踪中的行号。
