我想创建使用proguard的简单示例 在我的例子中，我在libs文件夹中有apfloat.jar lib，在xml中有onclick监听器。
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();
}
}
当我使用带有此配置的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
来避免此错误信息-dontwarn org.jscience.**
-dontwarn org.apfloat.**
当我使用此代码时，我的示例导出正常，但当我在手机中点击时，我点击按钮，我的应用程序崩溃 那怎么能解决这个问题呢？谢谢你的帮助。
答案 0 :(得分：1)
最后我找到了答案。
-dontwarn org.jscience.**
-dontwarn org.apfloat.**
-keep class apfloat.** { *; }
-keep class org.jscience.** { *; }
-keep class org.apfloat.** { *; }
