nit: Can we do it more gracefully? For example  get first app and make it
sticky?

Done.  We don't need that package_name.

+  store_app.name = "Store";
+  store_app.package_name = "com.android.vending";
+  store_app.activity = "com.android.vending.activity";
+  store_app.sticky = true;
+  fake_apps_.push_back(store_app);
+
   // Make sure we have enough data for test.
   for (int i = 0; i < 3; ++i) {
     arc::AppInfo app;
     app.name = base::StringPrintf("Fake App %d", i);
     app.package_name = base::StringPrintf("fake.app.%d", i);
     app.activity = base::StringPrintf("fake.app.%d.activity", i);
+    app.sticky = false;
     fake_apps_.push_back(app);
   }
