我试图混淆一个完全用 C++ 编写的完成的应用程序，只有下载和许可是用 java 编写的。它在不使用 proguard 的情况下工作得很好，但是一旦它被混淆，我在手机上启动应用程序时会出现以下错误。

我在 proguard.cfg 中使用了以下配置

-dontpreverify
-repackageclasses ''
-allowaccessmodification
-optimizations !code/simplification/arithmetic


-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public interface com.google.android.vending.licensing.ILicensingService

-keep public class * extends android.view.View {
    public <init>(android.content.Context);
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>(android.content.Context, android.util.AttributeSet, int);
    public void set*(...);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * implements android.os.Parcelable {
    static android.os.Parcelable$Creator CREATOR;
}

-keepclassmembers class **.R$* {
    public static <fields>;
}

-keepclassmembers public class com.google.android.vending.expansion.downloader.impl.DownloadsDB { 
    public static final java.lang.String * ; 
}

在构建应用程序时，它会给出一些警告，我不知道在使用 play_licensing 和 play_apk_expansion 的东西时如何解决。

第一次发帖的错误信息

无法启动活动 ComponentInfo{com.fantasyhaze.rememory/com.fantasyhaze.rememory.Main}：android.database.sqlite.SQLiteException：没有这样的表：MetadataColumns：，编译时：SELECT APKVERSION,_id,DOWNLOADSTATUS,DOWNLOADFLAGS FROM MetadataColumns LIMIT 1

表示 SQLite 数据库存在问题，因为缺少所需的表。

我建议使用dex2jar反编译 APK 文件，然后使用JD-GUI查看 Java 类文件，找出哪些 Java 类文件丢失或以某种方式被混淆，导致应用程序崩溃..

根据我个人的经验，Proguard 的大多数问题都与某些必要的属性被错误地混淆的类有关，或者在混淆过程中这些类刚刚被删除。

像这样的陈述

-保持公共类 * 扩展 android.app.Activity

在你的 proguard.pro 文件中允许你从 Proguard 的混淆过程中排除类

我最近遇到了这个错误，似乎在混淆代码后，反射停止在DownloadsDB课堂上工作。问题源于在DownloadsContentDBHelper.onCreate方法内部检索通过反射声明的嵌套类的问题，至少在我的情况下没有返回任何类。

所以我换了线

Class<?>[] arrayOfClass = DownloadsDB.class.getDeclaredClasses();

和

 Class<?>[] arrayOfClass = new Class[] {MetadataColumns.class, DownloadColumns.class};

手动指定所需的类。类字段也可以通过名称访问，因此我指示 proguard 完全保留类和所有成员：

-keep class com.google.android.vending.expansion.downloader.impl.DownloadsDB* {*;}

这似乎对我有用。
