It says that in order to check how to use it, we should check `ApiDemos/src/com/example/android/apis/content/InstallApk*.java` , but such a thing doesn't exist anymore.

The only remaining thing of the ApiDemos are APK files, such as on `.../Sdk\system-images\android-26\google_apis_playstore\x86\data\app\ApiDemos` .

Please offer updated sample there, with a tutorial of how to use it.

This is even more important as the ACTION_INSTALL_PACKAGE is deprecated and all apps are supposed to use the new session API, which leads to apps being restricted because of various apps using it, including the built-in apps and of Google itself:
