Why is my app crashing - Stopwatch?

[Anke]

@Ray_Li

the error that pops up on my phone says, "MIT AI2 Companion has stopped"

Works fine on my test devices.
What device and which Android version?

[Ray_Li]

Android Linux 8.0.0

[Anke]

Build the APK and try ...

@Ray_Li

MIT AI2 Companion

Which version?

[Ray_Li]

Version 2.63

Also building the APK gives this error:

I've downloaded the extension, how do I get the blocks in my app?

@Ray_Li

Also building the APK gives this error

No problem to build the APK, try this:

stopwatch_Anke.apk

I also tried my app (Companion & APK) on a very old Android 5 device. Works fine!

[Ray_Li]

Where do I go to run the APK file that you uploaded?

[Anke]

Download it to your computer, copy it to your test device and install.

Ray, you don't have to use an extension:

StopWatchHMS.aia (4.3 KB)

[Ray_Li]

Seems like your test works for me too...

[Anke]

@Ray_Li

Seems like your test works for me too

So where is your problem?
It should also work with Companion.

[Ray_Li]

Thanks! This works.

[Ray_Li]

I've resolved the issue, but thanks for your help, I appreciate it!

[Anke]

@Ray_Li

I've resolved the issue

And what was the problem?

[Ray_Li]

I think it was because my device can't handle the timer when it ticks too fast, but 1 second seems good enough.

[Anke]

My app works on all of my test devices (Companion & APK) Android 4.x, 5.x, 7, 8, 9, 11, 12.
So it should also work on yours!

Hi Ray

Here is the same code I uploaded before, but with an additional Clock that ensures the App's screen is always on display.
StopWatchHMS_2.aia (4.9 KB)

Try this one on your device (it shows even the millis):
