B4A B4XPages ScreenRecorder - version 0.7 (25/09/2016)
25/01/2021 - Updated the sample app to use SDK29, foreground services, and also wrote it as a B4XPages app. There are no changes to the library.
Here is a wrapper/library which lets you record the screen and save it as a video file.
It is using MediaProjection which is available from API 21 (Lollipop) and will not work on earlier versions of Android.
It is based on this Github-project. Kudos to the original author.
See next post for events and methods.
I am attaching a sample project along with the library.
Edit: The free version posted here is OK for screen-recording. There is also a more advanced version of this library which enables screen-recording with audio, capturing screenshots and screen-mirroring. Send me a PM (start a conversation) if you are interested.
Some basic stuff to remember:
1) you need at least Lollipop to get this to work. The library uses MediaProjection which was introduced with SDK 21.
2) You cannot use it for a spy-app. When users run your app and the code in your app which triggers the screen-capturing (recording or screenshots), users have to give permission.
3) some apps, such as Telegram, can block MediaProjection, and thus capturing/recording of the screen is not possible.
Please remember that creating libraries and maintaining them takes time and so does supporting them. Please consider a donation if you use my free libraries as this will surely help to keep me motivated. Thank you!
