My Apps just running 30 seconds then hang

[areripe]

Hello, sorry if I put my thread at wrong place. Because im new here. Im using DF Bluetooth v3 at 9600 boudrate to arduino.

But what happening here is, the data send from android to arduino is slow.
it takes 2 second delay to send to motor. And from arduino Im using DF robot motor controller.

And about the main problem is, my apps will run 30-40 seconds and then HANG or getting slower which means like not responding.

You should attach your project instead of posting the source code.

On the IDE, Click on File -> Export As ZIP

I'm having some problems runing your app.

1- If I don't have BlueTooth on I get a msgbox with an error, if I activate BlueTooth I get THIS error.

2- You have to remove the following lines out of the If FirstTime Then ...

Activity.LoadLayout("Main")
Serial1.Initialize("Serial1")
timer1.Initialize("Timer1", 1000)

Having those lines in FirstTime means that those lines will execute ONLY THE FIRST TIME your app runs.

3- It seems your app is for something specific, I can see a device when I tap on the "Find Device" button, but tapping on it displays THIS error after a few moments.

1. I never saw that error yet, im only get error when I try to connect samsung galaxy tab 2 with the apps. And the error code
java.oi.IOException : the connection have been refused.

2. If I remove that 3 lines, should I put it where? In activity_resume?

3. You need firstly paired the bluetooth adapter first in setting.
Then should be no problem with that error

No, just remove the "If FirstTime Then" and leave those lines in Activity_Create
