在类android.app.Notification $ Action中找不到引用的方法'android.app.RemoteInput [] getRemoteInputs（）'

Question

我从这个问题过去一周就陷入了困境。我正在尝试导出我的Android应用程序以进行最终发布，但它在导出时会出现以下错误。

Proguard returned with error code 1. See console

我在proguard-project.txt文件中使用以下条目。

-keepclassmembers class fqcn.of.javascript.interface.for.webview {
public *;
}
-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault

-keepclassmembers class * {

}
-keep class android.support.v4.** { *; }

如果我在proguard-project.txt文件中使用以下内容，我可以从eclipse成功导出我的.apk文件。但是当我在设备中安装并运行该应用程序时，它正在崩溃。

-keep class android.support.v4.** { *; }   
-dontwarn android.support.v4.**
-dontwarn javax.activation.**
-dontwarn javax.security.**
-dontwarn java.awt.**
-libraryjars <java.home>/lib/rt.jar
-keep class javax.** {*;}
-keep class com.sun.** {*;}
-keep class myjava.** {*;}
-keep class org.apache.harmony.** {*;}
-keep public class Mail {*;}        
-dontshrink
-dontwarn org.mockito.**
-dontwarn sun.reflect.**
-dontwarn android.test.**
-keep class javax.ws.rs.** { *; }
-dontwarn com.fasterxml.jackson.**
-dontwarn org.xmlpull.v1.**
-dontwarn javax.jdo.**
-dontwarn com.google.api.client.googleapis.extensions.android.gms.**

请帮帮我如何解决这个问题。我不能直接导出.apk文件而不使用proguard配置？谢谢。如果我需要提供更多信息，请告诉我。

Answer 1

也许有些支持v4类或接口混淆了，我试过这个并且它可以工作

-dontwarn android.support.v4.**     
-keep class android.support.v4.** { *; }   
-keep interface android.support.v4.app.** { *; }   
-keep public class * extends android.support.v4.**   
-keep public class * extends android.app.Fragment

我以这种方式成功解决了错误。

我的project.properties文件内容

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

# Project target.
target=android-19
android.library.reference.1=../appcompat_v7

我的proguard-project.txt内容

-keepclassmembers class fqcn.of.javascript.interface.for.webview {
public *;
}

# added to prevent runtime errors (kazsato)
-keep class * extends java.util.ListResourceBundle {
protected Object[][] getContents();
}

-dontwarn javax.jdo.**

我的proguard-google-api-client.txt

-keepattributes Signature,RuntimeVisibleAnnotations,AnnotationDefault

-keepclassmembers class * {
@com.google.api.client.util.Key <fields>;
}
