Provided that you are using the Endpoints client library that you generated for Android <https://cloud.google.com/endpoints/docs/frameworks/java/generate-client-libraries-android>, it's not necessary to manually add the headers yourself. You need to configure the client library to authenticate, and the full instructions for this are provided in the documentation Calling Backend APIs from an Android Client <https://cloud.google.com/endpoints/docs/frameworks/java/calling-from-android> .
