【转】can't find referenced method 'android.app.RemoteInput[] getRemoteInputs()' in class android.app.Notification$Action

I am kind of stuck from past 1 week from this issue. I am trying to export my android app for final release but it gives following errror while exporting.

Proguard returned with error code 1. See console

I am using below entries in my proguard-project.txt file.

I am able to export my .apk file successfully from eclipse if I am using below content in my proguard-project.txt file. BUT when I am installing and running that app in device , it is crashing.

-keep class android.support.v4.** { *; }   
-dontwarn android.support.v4.**
-dontwarn javax.activation.**
-dontwarn javax.security.**
