I am trying to use Ionic DevApp. When I develop on my personal PC, all works great. I can connect my iphone to the network wifi and see my app.
When I am at work, even though my laptop and iphone are on the same wifi, I cannot see my apps.
I can type the address in manually, and it does work…
I assume there is some proxy or firewall blocking this, but I don’t know what to check.
Can someone help?
Can you browse to it from your phone using Safari?
Http://ipaddress_or_machinename:8100
I had the same issue.
It’s called client isolation.
And it’s not something IT should be able to disable on a whim unless you have an iron clad business need.
Your best best Is to create a hot spot with you phone and connect the laptop to it.
The good news is that it’s easy to ask your IT if they are enforcing client isolation.
yes, I can browse from my phone. I can even use the “enter Address Manually” link on DevApp for IOS. Android does not have that though.
Suspect your Android is on a different WiFi
the biggest problem is the Android version of Ionic DevApp does not have the “enter address manually” link
Ya know I’ve never noticed.
Being honest I’m not a fan of that app as it’s so far away from what you would actually do yourself to not produce a result which can be taken seriously. I hardly ever use it.
From a development stance I much prefer to selectively inject providers based on if I’m using a browser or actual device when it comes to plugins etc, then you are not relying on hardware physically being there and working in order to develop your app.
Decoupling.
+1 for this. Use mocks for your plugins, or write a tiny service that uses a plugin if you’re on a device, and uses an Angular solution if you’re on a browser.
Just to add, here’s a repo I have created demonstrating this feature…
If you look at the app.module.ts you can see how I go about it - I detect to see if it’s running using cordova or not…
const cordovable = window['cordova'] !== undefined; //detect if cordova is running
then under the providers section…
providers: [
{ provide: PhotoTakerProvider, useClass: cordovable ? PhotoTakerProviderImpl : PhotoTakerProviderMock }
]
If you run it on both the browser using ionic serve and on a device using ionic cordova emulate android you will see it in action.
This is awesome stuff and will help me down the line.
However, still doesn’t help me test on the device. I have a starter account as we are doing a POC. We want to see if Ionic can do what we need it to. With the starter account, I can’t deploy to the device so I am tied to using the ionic devapp
Why can you not deploy it!?!?!?
If you must you could just install Android Studio and push it to an emulated (or real) Android for free… no certificates, no apple licensing etc…
Feel I’m missing a significant piece of the puzzle 
I bet I’m the one missing the pieces of the puzzle. You seem to know what’s going on LOL.
With the Ionic Pro Starter level we are on, you (as far as I know) build an APK file for example to put on the device. It won’t let me build binaries. Now of course, I could buy a pro account which may happen but I was looking to try this out (and the other tech we are evaluating) to decide.
If you’re running a PC of any kind you can install a android Studio from google which will give you the proper sdk’s to build the app and deploy to an android device for free.
It also includes the emulator.
> ionic cordova emulate android —livereload
Or
> ionic cordova run android —livereload
The second one to run on the device itself.
You can do the whole job lot including creating production builds for google play, but of course not Apple without having an Apple Developer account and a Mac / Ionic Pro.
Also… just thought of this. Sign up for a phonegap build account. They’ll build your android and iOS apps for free. Though once again for Apple you need a developer account in order to sign the ipa, even for developing.
I got android studio but it didn’t install an emulator. When I run this command:
ionic cordova emulate android --list
It shows no emulators.
I also tried loading the gradle file into Android Studio but it was reporting an error.
Gradle ‘android’ project refresh failed
Error:Cause: unable to find valid certification path to requested target
Go through something like this…
https://developer.android.com/studio/run/managing-avds.html
Get a virtual android device set up at a minimum. You might have to google a bit for help with setting up paths to the sdk n stuff, but at least if you get the virtual android device up and running you’re 90% of the way there.
I did this… and finally got android studio to show an emulator on its own.
However, it I try opening the build.gradle I got issues “unable to find valid certification path to requested target”
If I try to emulate from ionic cordova emulate android --list it shows no emulators.
when I try ionic cordova emulate android --target NEXUS_5X_API_25 it goes through says the app is deployed, but never opens the emulator (or use the open one if I have one)
Its amazing to have to go through all this to debug a login page. The concept of Ionic DevApp is great but if you can’t use it to debug the login…
Couple of things to try…
Can you just build your apk?
> ionic cordova build android
Also (assuming you can build), can you emulate without specifying an emulator?
> ionic cordova emulate android
Unfortunately, even though I do have JDK installed, it seems to not be happy:

[OK] Your app has been deployed.
Did you know you can live-reload changes from your app with --livereload?
Suspect your java_home path is wrong…
This is mine…
C:\Program Files\Java\jdk1.8.0_152
Update yours to a version you actually have that’s 1.8.x at least. Close your command prompt when done and reopen just to make sure the change takes effect.
Tbf you need to get this right to build anything Android so don’t think it would be smoother with any other framework.
The folder appears correct though:
C:\Program Files\java\jdk-9.0.4
I removed that version and put 1.8.0_162 and it seems at least try to compile it.
Sorry about this but it won’t let me attach as file.
