ElliotHC Active Member Licensed User Aug 7, 2019 #1 I need to trigger the built in camera on the Samsung Galaxy. I am currently using some hardware and the Mic/resistor switching method but I'd like to run an app in the background instead. Does anyone know if it's as simple as putting the volume down?

ElliotHC Active Member Licensed User Aug 7, 2019 #5 Can I tap the display somewhere from the background? Basically, I need to open the built in camera and take a slow motion video clip.. No B4A projects are going to cut it unless they can take a 960fps Upvote 0

MarkusR Well-Known Member Licensed User Longtime User Aug 7, 2019 #7 you can start something from a notification that is fixed at the top from a foreground service of your app. you need to know which data is expected in the intent that you can control your camera app. https://www.b4x.com/android/help/core.html#intent using your own app for capture video is also ok but the idea at android is that apps can working together.

I will be quite impressed if you can get the camera to take a 500-750ms video at 960fps. The Galaxy camera is constantly filming maybe 500ms before to capture the event. I need +/- 500ms from the trigger point. Still think you can make that work with B4A? Upvote 0

Brandsum Well-Known Member Licensed User Aug 7, 2019 #9 Sorry I didn't understand what you mean. Do you want to capture a 500ms video in 960fps? Or you want to record 500ms frames before you press capture button? And its not about the IDE but the platform. If its possible in Android then you can do it in B4A. Its an IDE. Upvote 0

You could try with Accessibility Services: https://www.b4x.com/android/forum/t...th-disabilities-automation-etc.95216/#content There are some Perform Actions included and shown in the sample which can simulate taps from a service. If you are unable to do it yourself, then I have built many custom solutions for B4X users who have had similar requirements, especially non-standard and edge-cases. Just send me a PM if you are interested. Upvote 0
