i tried adding below lines proguard-project.txt not working

-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.** {*;}

i found answer myself. adding below 2 lines in proguard-project.txt file solved problem.

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