It is technically possible to create an app (A) wich :
1) is launched automatically when the smartphone is on;
2) 10 seconds after launch the app B;
3) after 30 seconds press the button P1 of the app B;
4) after another 60 seconds launches the app C;
5) exit.
With the language VB6 I can do it in 1/2 hour, but in B4a ...
Thanks in advance
Steps 1, 3, 4 and 5 are possible (should take about 10 minutes to code). Use Project - Service - Start at boot.
Use a timer to start the other app by sending an Intent object.
Step 2 is not possible in Android due to security reasons.
