问题 I have specific case to ping my server every 10-60 minutes (it still depends) but only when app is opened. This feature is created to inform that session is still open where session is defined as period from app open to app close. I don't have to worry about process kill. What is better to use ?

问题 Developing an application for Android TV, I have a question on the use of ads. The Android TV layout guide states that: Advertising on Android TV must always be full-screen.

Android TV does not provide a web browser. Your ads must not attempt to launch a web browser or redirect to the Google Play Store.

问题 I am trying to detect when a device is capable of outputting at 4K UHD (3840x2160) resolution. A number of devices such as the nVidia Shield TV and the Sony Xperia Z5 Premium will report that they are running at 1080p even though they are capable of UHD, because they default to 1080p output for non-video layouts.

问题 I want to display two different types of cards in the same row (ListRow) . I tried to modify the Presenter class by adding viewType similar to dealing with displaying multiple row types in RecyclerVew but it did not work.
