【中文标题】使用 Proguard 混淆后的 SuperNotCalledException【英文标题】:SuperNotCalledException after obfuscation with Proguard 【发布时间】:2017-06-12 03:58:23 【问题描述】:

我有一个 android 应用,它的调试版本运行良好。然而,它的发布版本,包括对 ProGuard 的混淆(配置如下所示),不起作用,并且总是在启动时崩溃并显示以下日志:

我已经尝试添加所需的调用(覆盖错误片段中的onAttach()),但这并没有任何区别。有问题的片段在下面的代码中,它与库AppIntro 一起使用。这是FragmentIntro.java的代码:

公共类 FragmentIntro 扩展 Fragment 实现 ISlideBackgroundColorHolder /* 静态的东西 */ 私有静态最终字符串 ARG_LAYOUT_TITLE_ID = "titleId"; 私有静态最终字符串 ARG_LAYOUT_MESSAGE_ID = "messageId"; 私有静态最终字符串 ARG_LAYOUT_DRAWABLE_ID = "drawableId"; 私有静态最终字符串 ARG_LAYOUT_COLOR_ID = "colorId"; //private static final int layoutResId = R.layout.intro_fragment; /* 私有实例变量 */ private int titleRedId,messageResId,drawableId,colorResId,colorCode; 私有相对布局主布局; 公共静态 FragmentIntro newInstance(@StringRes int titleId,@StringRes int messageId,@DrawableRes int drawableId,@ColorRes int colorId) FragmentIntro fragSlide = new FragmentIntro(); 捆绑参数 = 新捆绑(); args.putInt(ARG_LAYOUT_TITLE_ID, titleId); args.putInt(ARG_LAYOUT_MESSAGE_ID , messageId); args.putInt(ARG_LAYOUT_DRAWABLE_ID , drawableId ); args.putInt(ARG_LAYOUT_COLOR_ID, colorId); fragSlide.setArguments(args); 返回 fragSlide; @覆盖 public void onCreate(@Nullable Bundle savedInstanceState) super.onCreate(savedInstanceState); if (getArguments() != null) this.titleRedId = getArguments().getInt(ARG_LAYOUT_TITLE_ID); this.messageResId = getArguments().getInt(ARG_LAYOUT_MESSAGE_ID); this.drawableId = getArguments().getInt(ARG_LAYOUT_DRAWABLE_ID); this.colorResId = getArguments().getInt(ARG_LAYOUT_COLOR_ID); @Nullable @覆盖 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) //super.onCreateView(inflater, container, savedInstanceState); //如果(容器== null)返回null; 查看视图 = inflater.inflate(R.layout.intro_fragment, container, false); Utils.globalAppContext = getContext().getApplicationContext(); colorCode = ContextCompat.getColor(getContext().getApplicationContext(), colorResId); mainLayout = (RelativeLayout) view.findViewById(R.id.introLayout); mainLayout.setBackgroundColor(colorCode); ((TextView) view.findViewById(R.id.textViewIntroTitle)).setText(titleRedId); ((TextView) view.findViewById(R.id.textViewIntroMessage)).setText(messageResId); ((ImageView) view.findViewById(R.id.imageViewIntro)).setImageDrawable(Utils.getDrawableFromResource(drawableId)); 返回视图; @覆盖 公共无效 onSaveInstanceState(捆绑 outState) outState.putInt(ARG_LAYOUT_TITLE_ID, titleRedId); outState.putInt(ARG_LAYOUT_MESSAGE_ID, messageResId); outState.putInt(ARG_LAYOUT_DRAWABLE_ID, drawableId); outState.putInt(ARG_LAYOUT_COLOR_ID, colorResId); super.onSaveInstanceState(outState); @保持 @TargetApi(23) @覆盖 公共无效onAttach(上下文上下文) super.onAttach(上下文); @保持 @SuppressWarnings("弃用") @覆盖 公共无效 onAttach(活动活动) super.onAttach(活动); @覆盖 公共无效 onDestroy() super.onDestroy(); @覆盖 公共无效 onPause() 超级.onPause(); @覆盖 公共无效 onResume() 超级.onResume(); @覆盖 公共无效 onStart() super.onStart(); @覆盖 公共无效 onStop() 超级.onStop(); // ISlideBackgroundColorHolder 的实现 @覆盖 公共 int getDefaultBackgroundColor() 返回颜色代码; @覆盖 公共无效 setBackgroundColor(@ColorInt int backgroundColor) mainLayout.setBackgroundColor(backgroundColor);

我正在使用的 proguard 配置文件是这个(并且只有这个):

我已经忘记了我花了多少小时试图解决这个问题,特别是因为一切都在调试模式下运行,并且没有任何关于 super.onAttach() 的投诉。只有在混淆了上面的配置后才会失败。

非常感谢您的关注,感谢您的帮助。

最好的问候。

【问题讨论】:

【参考方案1】:

我让它工作了。就像 Doron 建议的那样,这可能与混淆有关,而不是与代码本身有关。

我将在此处发布我的方法和最终的 proguard.cfg 文件,仅供面临相同问题的人以及如何 [可能] 解决该问题的参考(请注意:这涉及很多麻烦!)。

由于我也怀疑它与类或代码无关,所以我做的第一件事就是删除所有不必要的覆盖,让两个类都被混淆并禁用所有优化。这是通过我的 ProGuard 配置中的这些设置完成的:

-optimizations no_optimizations

解释:no_optimizations 只是一个空的占位符。这对 ProGuard 没有任何意义。你可以在那里很好地使用“黄瓜”这个词,它会产生同样的效果。这只是意味着不会运行任何优化。与不指定-optimizations指令不同,这意味着所有的优化都会运行。

我还注释掉了 FragmentIntro 类和 ActivityIntro 的所有 -keep。我做了一个发布编译和测试。它优雅地跑着!上述文件(在 OP 中)中显示的所有其他混淆选项均已打开并保持原样。

然后肘部油脂开始:我创建了一条线,每个 ProGuard 优化都被明确拒绝:

-optimizations !class/marking/final,!class/unboxing/enum,!class/merging/vertical,!class/merging/horizontal,!field/removal/writeonly,!field/marking/private,!field/propagation/value,!method/marking/private,!method/marking/static,!method/marking/final,!method/removal/parameter,!method/propagation/parameter,!method/propagation/returnvalue,!method/inlining/short,!method/inlining/unique,!method/inlining/tailrecursion,!code/merging,!code/simplification/variable,!code/simplification/arithmetic,!code/simplification/cast,!code/simplification/field,!code/simplification/branch,!code/simplification/string,!code/simplification/advanced,!code/removal/advanced,!code/removal/simple,!code/removal/variable,!code/removal/exception,!code/allocation/variable

然后我开始一次允许 1 次优化,每次我进行发布构建时,都安装在模拟器上并查看应用程序是否运行。

如果该优化导致应用程序正在运行,我将其保留为不带感叹号 (!),这意味着它是允许的,否则我会将感叹号放回原处并继续进行下一个优化:删除标记,发布构建,安装,测试。

我这样做了 29 次,每次优化一次,只是为了弄清楚是什么优化导致我的代码崩溃。

最后,我找出了所有不需要的优化并得到了这个:

-optimizations class/marking/final,class/unboxing/enum,class/merging/vertical,class/merging/horizontal,!field/removal/writeonly,field/marking/private,field/propagation/value,method/marking/private,!method/marking/static,method/marking/final,!method/removal/parameter,method/propagation/parameter,method/propagation/returnvalue,method/inlining/short,method/inlining/unique,method/inlining/tailrecursion,code/merging,code/simplification/variable,code/simplification/arithmetic,code/simplification/cast,code/simplification/field,code/simplification/branch,code/simplification/string,code/simplification/advanced,!code/removal/advanced,code/removal/simple,code/removal/variable,code/removal/exception,!code/allocation/variable

上面的行,清理后只拒绝(感叹号)不需要的优化,相当于:

-optimizations !field/removal/writeonly,!method/marking/static,!method/removal/parameter,!code/removal/advanced,!code/allocation/variable

由于没有完成上述优化,我的代码编译并运行良好。另一方面,如果我允许上述任何优化,它会在启动时崩溃。

这就是我清理后的工作 proguard.cfg 文件的最终结果:

    @android.support.annotation.Keep <fields>;


-keepclasseswithmembers class * 
    @android.support.annotation.Keep <init>(...);

我不知道为什么提到的标记优化会破坏我的代码,尽管我怀疑它优化了 v4.app.Fragment 相关类中的某些内容(特别是 v4.app.FragmentManager,在第 1230 行,阻止了它正确调用 onAttach() 并将 f.mCalled 设置为 true)。顺便说一句,我正在使用 Android 支持库 25.1.0。

无论如何,感谢您的时间和关注,我希望上述解决这个烦人问题的方法对某人有所帮助。

由于您在调试中工作,问题可能仅与混淆有关,与您的实际代码无关。

您是否尝试将整个班级保持在 proguard 中:

-keep class com.alxdroiddev.cameragear.utils.FragmentIntro  *;

【参考方案3】:

您是否尝试过仅删除这些行:

@Keep
@TargetApi(23)
@Override
public void onAttach(Context context) 
    super.onAttach(context);


@Keep
@SuppressWarnings("deprecation")
@Override
public void onAttach(Activity activity) 
    super.onAttach(activity);

【讨论】:

这些行是试图摆脱错误的失败尝试。由于日志消息抱怨他们不存在,我只是把它们放在那里(连同其他简单地调用它们的超级方法的覆盖)。我认为他们不会造成伤害。
