Android项目：导出问题启动取消！ Proguard返回错误代码1.请参阅控制台

概述我在project.prperties中没有评论下面的行 proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 工作准备工作正常工作. 但是当我添加了android-support-v4.jar库时,在导出签名的应用程序项目时出错 Launch canceled! Proguard 我在project.prpertIEs中没有评论下面的行

proguard.config=${sdk.dir}/tools/proguard/proguard-androID.txt:proguard-project.txt

工作准备工作正常工作.

但是当我添加了androID-support-v4.jar库时,在导出签名的应用程序项目时出错

我试图添加以下行proguard-project.txt,但它不工作

-dontwarn androID.support.**-dontwarn com.Google.ads.**-libraryjars libs/androID-support-v4.jar-keep public class * extends com.phonegap.API.Plugin -keep public class org.apache.cordova.DroIDGap -keep public class org.apache.cordova.** -dontwarn androID.webkit.*-dontwarn org.apache.**-dontwarn  androID.support.v7.Widget.**-keep class androID.support.v7.Widget.** { *; }-dontwarn com.Google.ads.** -keep class com.Google.ads.** {*;}-keep class com.Google.androID.gms.analytics.**-keep class com.Google.analytics.tracking.**-dontwarn com.Google.androID.gms.analytics.**-dontwarn com.Google.analytics.tracking.**-keep class com.Google.ads.**  { *; }-dontwarn com.Google.ads.**-keep public class com.admob.androID.ads.** {*;}

解决方法 我自己找到答案
在proguard-project.txt文件中添加以下2行解决了问题.

-dontwarn com.Google.androID.gms.*-ignorewarnings
