@don any update / thoughts on this?

don commented 11 years ago

I haven't had a chance to look into this. I need to look at the lifecycle, this used to be handled ok. Are you seeing any problems or just errors? I'm hoping to get some time for this and 2.8 updates next weekend.

JohnMcLear commented 11 years ago

The problem /error is that on Android when you end any app using this plugin that has the listener added the application exception errors and the users see this error.

Looking forward to next weekend, will keep my eyes pealed :)

don commented 11 years ago

I created a sample app with Cordova-2.8 and didn't see this error using these instructions https://github.com/chariotsolutions/phonegap-nfc/blob/master/doc/GettingStarted.md

@JohnMcLear let me know if you're still seeing this with Cordova-2.8

JohnMcLear commented 11 years ago

Will do.

@JohnMcLear in the example above, you're mixing cordova-cli and plugman.

If you use cordova-cli to create the project, use "cordova plugin add ..\phonegap-nfc"

If you used the zip version of cordova to create the project, then it would be appropriate to use plugman to install the plugin.

See these documents for more details https://github.com/chariotsolutions/phonegap-nfc/blob/master/doc/GettingStarted.md https://github.com/chariotsolutions/phonegap-nfc/blob/master/doc/GettingStartedCLI.md

don commented 11 years ago

@albi87 can you try upgrading your command line tools and project to Cordova 2.8? You'll need to make sure the new jar file and cordova.js get into your project.

don commented 11 years ago

@JohnMcLear I think you need to upgrade to 2.8 also. You updated the command line tools, but the code is still 2.6.

You updated the version of the command line tools, but the generated project still contains the old cordova. https://github.com/mclear/my/tree/master/platforms/android/libs

Can you move assets/www/* to a new directory and re-generate the android project and install the latest phonegap-nfc? I did this to the example project that you were working on with devgeeks https://github.com/don/phonegap-nfc-test/tree/cordova-2.8

asnp87 commented 11 years ago

@don today i will try to update cordova!

Looks good :)

JohnMcLear commented 11 years ago 
D:\foo>cordova plugin add ..\phonegap-nfc
Plugin "com.chariotsolutions.nfc.plugin" already installed, 'sall good.

D:\foo>cordova plugin list

D:\foo>

list may be broken. Reported to Cordova guys on IRC

however

D:\foo>type platforms\android\assets\www\cordova_plugins.json
[{"file":"plugins\\com.chariotsolutions.nfc.plugin\\www\\phonegap-nfc.js","id":"com.chariotsolutions.nfc.plugin.NFC","runs":true}]
D:\foo>

So looks fine however..

<devgeeks>heh
<JohnMcLear_>for anyone who wants to create an issue ;)
<JohnMcLear_>also
<devgeeks>list will list plugins installed properly
<JohnMcLear_>cordova plugin add *second plugin* breaks functionality
<JohnMcLear_>it overrides cordova_plugins.json
<devgeeks>that error will get thrown for half-installed or badly removed ones
<JohnMcLear_>removes the previous reference

So my takeaway from this is that cordova plugin list is probably broken.

Hey @don I get Error on application exit still

Updated cordova to 2.8.15 Using latest phonegap-nfc

Steps to replicate: Follow the steps on https://github.com/chariotsolutions/phonegap-nfc/blob/master/doc/GettingStartedCLI.md Scan a tag Hit the BACK BUTTON.

This will cause the error, using the home button doesn't fire the same error..

Phew that was hard work.. Trace

woohooo, was it easy to replicate? :) will try this..

JohnMcLear commented 11 years ago

Tested perfect, or so it seems. Any idea why this was missed/explanation so I know for debug purposes in future?

It has something to do with the way cordova manages the plugin lifecycle.

From watching the logs, cordova was calling nfcPlugin.onPause(true) then nfcPlugin.onPause(false) when the back button was hit.

The 2nd time onPause was called, the app was in the background, and the plugin was trying to disable foreground nfc dispatching, which causes an error if app isn't in the foreground.
