This commit adds a verifier that verifies a host delegates permission for an app to handle Url for the host using the Statement protocol. - Implements the Statement protocol -- The protocol defines a file format that represents statements. -- The protocol defines where each asset type should put their statement declaration. For web asset, the statement file should be hosted at <scheme>://<host>:<port>/.well-known/associations.json. - Implements IntentFilterVerificationReceiver, an interface between StatementService and PackageManager. PackageManager will send a broadcast with action Intent.ACTION_INTENT_FILTER_NEEDS_VERIFICATION. The service will process the request and returns the results by calling PackageManager.verifyIntentFilter(). To verify an IntentFilter like this defined in Android app com.test.app <intent-filter> <data android:scheme="https" /> <data android:host="www.test.com" /> <data android:pathPattern=".*"/> </intent-filter> The service will try to retrieve the statement file from https://www.test.com:443/.well-known/associations.json and try to find a JSON object equivalent to {'relation': ['delegate_permission/common.handle_all_urls'], 'target': {'namespace': 'android_app', 'package_name': 'com.test.app', 'sha256_cert_fingerprints': [APP_CERT_FP]}} The entry should have the correct relation, package name, and certificate sha256 fingerprint. Because this implementation will send a HTTP request for each host specified in the intent-filter in AndroidManifest.xml, to avoid overwhelming the network at app install time, we limit the maximum number of hosts we will verify for a single app to 10. Any app with more than 10 hosts in the autoVerify=true intent-filter won't be auto verified. Change-Id: I787c9d176e4110aa441eb5fe4fa9651a071c6610
