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

Question

我在project.prperties下面的行中没有注释

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

工作进展,它工作正常.

但是当我添加android-support-v4.jar库时,导出已签名的应用程序项目时出错

Launch canceled!
 Proguard returned with error code 1. See console

我尝试将下面的行添加到proguard-project.txt但它不起作用

-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.** {*;}

Answer 1

我自己找到了答案.在proguard-project.txt文件中添加以下2行解决了这个问题.

-dontwarn com.google.android.gms.*
-ignorewarnings
