hi,

I have created an app that reads the nfc card data. It works perfectly fine as long as the app is in the foreground. But in my app I invoke another plugin which comes on full screen and when that happens my app (which listens to nfc) stops listening and the built in nfc reader in Android responds.

I believe this is because Android suspends my app the moment something else takes over the screen, even though that 'something' is a plugin that I can calling from within my app. Any solutions?

I believe one solution would be to write some background service. Is there a simpler way for now? I just need my app not to be suspended when i invoke the plugin. Can I fiddle around with the launchmode / intents etc to achieve this?

Thanks,
Murali

Murali,

I assume your tried using setInterval ... And called the plugin from inside the interval function ??

Best,
Bruce

hi Bruce,

Yes, I did put up a setinterval and tried writing something to the console. But it stops once I invoke another plugin ( It's a camera plugin.)

Now I am trying out something called the foregroundcamera plugin which presumably doesn't kill (or suspend) the app from where it's called.

Thanks,
Murali

Yes, and I also tried to invoke the plugin in a few different ways, for example I even tried calling it through the nfc initialise / start event. But so far once the camera plugin's up, the nfc falls back to the Android OS default app. I can perhaps try with setting mime types n stuff so that Android may try to 'wake' up my app once a nfc tag is scanned. But doesn't seem elegant enough for me

Cheers,

Murali,

Thanks for sharing.... Interesting problem that seems to defy the definition of 'background process'.....

Hello Murali,

Is there a simpler way for now?

Unfortunately, no.
Appery.io generates hybrid app, which intercommunicates with OS via phonegap plugins, so if you want to launch,kill thread/process, add hardware functionality, then you need to find or write a phonegap plugin, and then integrate it in Appery.io project.
