zmNinja complied from sources for Android and push notification

[tecufanujacu]

I have just compiled zmNinja for Android from sources but I have a question, in your guide at step 5 there is this:

configure zmNinja for push notification (optional)
If you want to enable zmNinja to receive push notification, you have to install the phonegap-plugin-push.
cordova plugin add phonegap-plugin-push --variable SENDER_ID=XXXXX
Where the XXXXXXX in SENDER_ID="XXXXXXX" maps to the project number in the Google Developer Console. If you are not creating an Android application you can put in anything for this value.

but If I don't have a SENDER_ID I can't use the push notifications, right?
In this case if I start a new project to get a google SENDER_IT can then I use it without costs?

To be honest, I'm not a 100% sure its needed. I added it because the plugin doc for push said so. I already have a sender ID in package.json - not sure which one is used. This entire ID and how it works if you compile yourself is not completely clear to me - feel free to try and let me know (But yes, GCM push is free) (see this if it helps)

Well, I have just configured your server and everything is working fabulously, thanks a lot for your work.
The push notifications are working without problems but I don't know if they are working thanks to the WebSocket or to GCM, is there some way to check this? (and eventually sorry for the stupid question).

P.S.: I only have a little problem, sometime zmNinja crashes at exit, I'm on Android 6.0.1 (with cm13). From the logcat I can't see nothing, what could I do?(sorry for the OT)

[pliablepixels]

Ok great. To test that, you can kill the app from the task switcher and force a push. If it gets it, then its GCM

Not sure I can offer much perspective, especially if logcat is not showing anything about the crash on exit as it doesn't happen with me. However, when you say 'exit' what does that mean? Switching the app to the background, killing it via task bar or using the "exit" menu option?

[tecufanujacu]

Well GCM is working :-) I don't use gapps, I use microG and I can clearly see the app zmNinja registered for the push notifications, sorry for my previous questions, I had forgotten that I can see this from microG.
Anyway I haven't set any SENDER_ID but I left the one that was present at build time.

About the crash at exit this happens when I press the exit button in the app and when I press the android back button, I have this problem on two phones, here the log:

Two questions:

• is normal that zmNinja is the bigger battery drainer on my phones?
• are you sure that have we to install the cert file for the ssl on our phones? I'm using two phones for my tests and I have installed the cert on only one phone but the notifications work on both the phones.

[pliablepixels]

a) Battery - yes. If you are looking at montage, zmninja is essentially grabbing JPEG images every 2 seconds from your monitors. Try switching to "low bandwidth" mode

b) No, you don't need SSL certs - they are not related to notifications. they are for to SSL access to ZM and that too only if you enable strict SSL certs. Can you point me to the documentation that says you need it? I'll fix it

[tecufanujacu]

About the certificate, in this page:
https://github.com/pliablepixels/zmeventserver

In the section SSL certificate:

Once that certificate is done, you also need to install it on your phone - thats as simple as emailing yourself the ".crt" file and double tapping it to install it.

About the crash the strange thing is that now this happens only on one phone, If you want I took a full log.

As second thing, I'm having problems with notifications, but for this I open a new issue.
