使用 proguard 的 Android 混淆应用程序保留 jar 库

Question

我想创建一个使用 proguard 的简单示例。
在我的示例中，我在 libs 文件夹中有 apfloat.jar lib，在 xml 中有 onclick 侦听器。

public void f1(View item) {

    if (item.getId() == R.id.button1) {

        Apfloat x = new Apfloat("100");
        x = x.add(new Apfloat("10"));
        Toast.makeText(getApplicationContext(), "clicked "+x.toString(true).toString(), 5).show();

    }

}

当我在这个配置中使用 proguard 时

# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
#-dontoptimize
-dontpreverify

# If you want to enable optimization, you should include the
# following:
# -optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
# -optimizationpasses 5
# -allowaccessmodification
#
# Note that you cannot just include these flags in your own
# configuration file; if you are including this file, optimization
# will be turned off. You'll need to either edit this file, or
# duplicate the contents of this file and remove the include of this
# file from your project's proguard.config path property.

我知道我可以使用

避免此错误消息

-dontwarn org.jscience.**
-dontwarn org.apfloat.**    

当我使用此代码时，我的示例导出正常，但是当我在电话中吃午饭并单击按钮时，我的应用程序崩溃了。
那么我该如何解决呢？感谢您的帮助。

Answer 1

我终于找到了答案。

-dontwarn org.jscience.**
-dontwarn org.apfloat.**

-keep class apfloat.** { *; }
-keep class org.jscience.** { *; }
-keep class org.apfloat.** { *; }
