新建Android程序的时分发生了找不到 \android-sdk-windows\tools\lib\proguard.cfg
网上看到的，自己用过了，绝对完美。
原因：
SDK不完整。
解决方法：
可在 \android-sdk-windows\tools\lib\目录下新建一个proguard.cfg文件
然后添下以下内容：
proguard.cfg-optimizationpasses 5
dontusemixedcaseclassnames
dontskipnonpubliclibraryclasses
dontpreverify
verbose
optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
keep public class * extends android.app.Activity

keep public class * extends android.content.ContentProvider
keep public class com.android.vending.licensing.ILicensingService
keepclasseswithmembernames class *{

}
keepclasseswithmembernames class *{

}
keepclasseswithmembernames class *{
public <init>(android.content.Context, android.util.AttributeSet, int);
}
keepclassmembers enum *{
public static **[] values();
public static ** valueOf(java.lang.String);
}
keep class * implements android.os.Parcelable {
public static final android.os.Parcelable$Creator *;
}
