我正在尝试创建一个 APK 文件，但是当我在导出对话框上按 Finish 时，出现错误，并且没有创建 APK。到目前为止在网上找不到任何东西，也许这里有人可以帮忙？错误：

Proguard returned with error code 1. See console
Warning: com.google.ads.util.i: can't find referenced method 'void setMediaPlaybackRequiresUserGesture(boolean)' in class android.webkit.WebSettings
      You should check if you need to specify additional program jars.
Warning: there were 1 unresolved references to program class members.
         Your input classes appear to be inconsistent.
         You may need to recompile them and try again.
         Alternatively, you may have to specify the option 
         '-dontskipnonpubliclibraryclassmembers'.
java.io.IOException: Please correct the above warnings first.

    at proguard.ProGuard.main(ProGuard.java:492)

我试图添加

-dontskipnonpubliclibraryclassmembers

但没有帮助。我正在使用广告，这是一个普通的 android 应用程序，在模拟器中运行良好。

我的 proguard.config 默认为空

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

还有我的 project.properties：

# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
# 
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.
target=android-16

谢谢

ps：这些默认的 android proguard 设置是否足够安全以防止基本的“黑客攻击”？（如果我能让它可行）

正如警告消息所示，Google Ads 库引用了您的目标运行时 (android-16) 中不存在的方法。此方法仅存在于 android-17 中。您应该指定 android-17 或更高版本的目标，以便 ProGuard 可以找到方法并正确分析代码。

如果应用程序仍然可以在其他目标上运行，您仍然可以在 AndroidManifest.xml 中指定其他目标。

ProGuard 提供了一些针对静态分析的基本保护：它混淆了标识符并修改了代码的结构。要获得更多保护，您可以考虑其商业兄弟DexGuard，它通过字符串加密、类加密和篡改检测等技术增加了针对静态分析和动态分析的更多保护。没有什么是牢不可破的，所以最终对你和潜在的黑客来说，这是一个经济上的权衡，时间、精力、金钱、收益、专业知识……

我已经解决了添加：

  -dontwarn com.google.ads.**

之后-verbose。例如

-optimizationpasses 5                                                                                          -dontusemixedcaseclassnames                                                      
-dontskipnonpubliclibraryclasses                                                 
-dontpreverify                                                                   
-verbose                                                                         
-dontwarn com.google.ads.**                                                      
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
