Here is my first application
It is a simple voice recorder using the excellent audio streamer
Some nice features :
- haptic interface to start/pause/stop recording with special phone positions
- phone call recording/pausing when shaking the phone
- automatic recording of agenda events (with special keywords)
- dropbox sync
- experimental Automatic Gain Control for Phone recording
- mp3 recording
You will recognize a lot of your nice libraries... Thank you to all of you
I really enjoy B4A it is so easy to develop an App when you already know dotnet...
I tried to code an app for my IPAD with objective C... sooo long learning curve ... B4A is GREAT
The App is here : JG Secret Recorder
It may not work properly with your phone as "phone audio recording" seems to highly depend on your specific hardware...
The app also uses accelerometer in the background (but without draining the batt) and, whith some smartphones, sensors are disabled when screen is off (Xiaomi Mi2s for example)... so try the app, it's free !
 : version V1.11 includes new V1.62 audio streamer library. Corrects a lot of App crashes when several Apps conflict to access audio stream
 : version V1.15 includes liblame for mp3 encoding. Many thanks @warwound
