Android 8 failure of Remainder or Modulo blocks in timer code

[Bill Cuthbert]

I have this issue on Android 8 - OK on Android 5. My App fails after about 4 minutes with message 'App stopped working'.

I found the the quotient worked but failed when using Modulo and Remainder. I got round this by using subtraction and multiplication to replace the Remainder / Modulo code. This  modified code now works on my Android 8 J3 Samsung 2017 phone. My App is a Speech Time system linked to Bluetooth LEDs, the failing code is within the clock timer block. I have attached a copy of the code that does not work alongside the code section that does work i.e removing the remainder or modulo blocks.

Hi Bill,

Do you see this problem in the companion, compiled app, or both?

Evan

Evan, I saw this problem on the compiled App (I do not use the companion). As a member of a local Speaker's club, I built a Bluetooth unit connected to my App using old Android phones (Android 5 mainly). On the recent purchase of my own Samsung phone (Android 8) I was surprised to see my App fail in this manner. After 2 days investigating the issue I found these maths blocks to be the root cause but no idea why.

Hi Bill,

Unfortunately, I haven't been able to replicate this with the Android emulator, and I don't have a Samsung device on hand at the moment to check if it's device-specific. Can you capture a log from your phone and send it to me? It will help us track down the source of the issue.

Regards,

Evan
