zmNinja build from source does not load on iOS 9.x - hangs on splashscreen

[tonymande]

zmNinja v1.1.2 does not load on iOS 9.x. It starts to load but then it stops showing the splash screen and keeps hanging there infinite.

Here's the output from Codes console:

Argh, looks like the new reachability code is causing more problems than it solves. @tonymande can you enable debug logs (its in dev settings) and email me copy? What is happening - is it forever stuck or does it drop you into the login screen after a while?

[tonymande]

Which dev settings do you mean? The ones in zmNinja I'm not able to reach. I'm not able to go behind the spashscreen. The app just got stuck there.

Ok, followed your advice to delete the app completely. After doing so I was able to launch zmNinja once and enable "debug log" under "dev settings". When closing the app and starting again, it shows the original behaviour and freezes showing the splash screen. I left the app in this state and here's the complete log. Unfortunately there are not much debug statements until this point and after a while the app crashes.

Message from debugger: Terminated due to memory issue

[pliablepixels]

this is very odd. I am using an iPhone 5S with 9.2.1. It seems to be running out of memory, which is very odd.

Questions:

1. Which is the last version of the app that worked? I did not add any features between 1.1 and 1.2 that were heavy in nature
2. Did anything change in your iPhone since the last working version?
3. Are you running your own version compiled from source code or did you buy it from the app store? The last message says "Message from debugger" like you are running it via Xcode?
4. Which iPhone model?
5. How many monitors?

[tonymande]

1. I don't know which was the last working version I just discovered zmNinja a few days ago. 1.2.1 is the first version I tried.

2. I never got the app working correctly. Everything is fine for the first startup after installing the app. But when I close it and open it again it get's stuck.

3. I took version 1.2.1 from github and compiled it by myself. I want to use my own push infrastructure, that's the main reason.

4. I'm using a iPhone 6 64GB with 9.2.1.I also tried a iPad Air 2 running iOS 9.1

5. Actually there are 4 monitors

One thing I noticed is that sometimes the cordoba lib prints a warning:
2016-03-26 08:41:52.864 zmNinja[1725:649593] THREAD WARNING: ['Device'] took '34.388672' ms. Plugin should use a background thread.

I don't know if it's related to my problem, but In general there seems something being loaded in the main UI thread.

[pliablepixels]

That warning can be ignored.

So I am on a less capable iPhone than you are with 7 HD monitors. Some thoughts come to mind:

1. Do a git update so you have my more recent code checkins
2. Monitor the memory buildup on Xcode and let me know what you see - its the solid and dotted line icon on the left (see image)
3. If at all possible, please email me test account on your server - I want to see if there is something there that is causing a problem
4. zmNinja comes with a demo acct - when you install the app new, go to settings, tap on the arrow icon on the top and select zmNinjaDemo and hit save - see if that works

Hi,
ok, I tried with the recent master (v1.1.3). There's no difference. ZmNinja eats my memory. Shortly after the second memory warning the process gets killed by iOS.

I also tried the Demo-Account. There's no difference. The app gets killed due to its memory consumption.

I'll set up an account on my system for you and send you an eMail with the credentials. But before doing so I first have to make the server available in the internet, currently it's only available through VPN.

[hableel]

I have same problem. some times it stuck on splash screen and some times works fine.
This happens with no editing or changing anything, tried version 1.1.2 and 1.1.3

[pliablepixels]

This is almost 5x the memory I am seeing. Try this - go to zmNinja/www/img - there is a file called background.png - delete it. It will mess up the screen display during initial load, but let me know if it works and memory consumption decreases.

[pliablepixels]

BTW, zmNinja does not work well on the simulator - please don't try loading it in the simulator.

[hableel]

It happened even in iphone 6s (9.3) and ipod touch 6th (9.3)

[tonymande]

Deleting the file also makes no difference. Still 9 out of 10 attempts to start the app result in getting stuck and eating memory.

@pliablepixels: Maybe you could provide some information how to debug the javascript code. I'm familiar with debugging in Xcode but unfortunately I have no experience in debugging cordova or javascript inside a iOS-App. With some help I'm pretty sure I'll be able to pinpoint the line of code which is responsible
