Release apk not working after enabling proguard, not able to debug too

Question

I am able to install the app in the device, but the app is not connecting to server . I am unable to debug the release apk too. When I disable proguard, the app gets connected to the server and I am able to debug the release apk too. I tried using proguard versions 4.7,4.9 and 5.2.1 . My Android version is 19 and my tools version is 20. I am using eclipse.

I have successfully used proguard 4.9 in my previous release to production.After my previous release to production, I had made two major changes to my code . I upgraded google-play-services and used jarjar to trim it and I upgraded the sdk tools to version 21 and then downgraded to version 20 due to some issues.

I would like to know what all I can try to figure out what is going wrong when I enable proguard . Something that seemed relevant that I picked from LogCat is below :

Your Proguard configuration is incorrect for one of the two things you just changed. Google Play Services details are here. They state you need to add the following ProGuard configs:

-keep class * extends java.util.ListResourceBundle { protected Object[][] getContents(); }

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable { public static final *** NULL; }

-keepnames @com.google.android.gms.common.annotation.KeepName class * -keepclassmembernames class * { @com.google.android.gms.common.annotation.KeepName *; }

-keepnames class * implements android.os.Parcelable { public static final ** CREATOR; }

I have added this to proguard-project.txt but it did not help. – maya Jul 29 '15 at 05:08
To double check if this inturn is caused by using jarjar to trim googleplayservices, I disabled the feature that required latest googleplayservices and used an old version without trimming that did not cross the dex limit . I still get the issues mentioned . – maya Jul 29 '15 at 05:37
