如何解决：新建Android程序的时候发生了找不到 \android-sdk-windows\tools\lib\proguard.cfg文件 的错误

问题概述：在新建Android程序的时候出现以下错误：找不到 \android-sdk-windows\tools\lib\proguard.cfg文件 原因：SDK不完整。 解决方法：方法一可在 \android-sdk-windows\tools\lib\目录下新建一个proguard.cfg文件然后添下以下内容：

-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.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 class com.android.vending.licensing.ILicensingService

-keepclasseswithmembernames class * {
native <methods>;
}

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

-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 *;
} 方法二通过Android SDK and AVD Manager更新所有SDK。
