when I use market API(androidmarketapi-0.6.jar).It's showing me error on below code.
String query = "maps";
AppsRequest appsRequest = AppsRequest.newBuilder()
The type com.google.protobuf.GeneratedMessage$Builder cannot be
resolved. It is indirectly referenced from required .class files
It means: "A class that you use needs another class that is not on the classpath." You should make sure to add the required jar to the classpath.
You do not need to do anything specific for this. Since you mentioned that you are using Android Play, the update notification is taken care of by Google Play.
You need to just update the APK with higher
versionCode and Google Play should do the rest.
BUT MAKE SURE:
