How can I change the app icon and name of an Ionic app during runtime?

I'm trying to hide my app or change the icon and name after the user takes some action, I don't know if there's a way to do this because the main idea is the app looks unnoticed for other users besides the phone owner.
I've been reading some things about how to do this on android but I can't find anything on ionic or cordova, so I'm looking for some guidance to do this
I hope you can help me!
I don't understand why you would need to change the app icon or name depending on what the user does, but even then, all of the things I have read conclude that there is no way to do this, at least on iOS.
You can check out some similar questions here, here and here. Although I must admit that these resources are quite outdated. Regarding your question, the only technology within Ionic that would be able to do this is Cordova and if it is not possible natively, which seems to be the case for iOS, then there is nothing that Cordova can do.
If you have found a way to do this on Android, then you would have to build your own Cordova plugin to handle it, because there doesn't seem to be anything out there that can do this.
you can do this on iOS 10+. check this out:

haven't been able to find a solution for Android yet, if it is possible at all.

What's the meaning of DISALLOW_FUN in Android's source code?

From http://developer.android.com/reference/android/os/UserManager.html, we can find a weird string variable named DISALLOW_FUN, which Specifies if the user is not allowed to have fun.
However, I cannot understand what it means.
Any explanation?
It's an attempt to make Android compatible with Windows Phone users.
AFAIK, it is an Easter egg, along the lines of GRAVITY_DEATH_STAR_I and many other similar jokes in the SDK.

Get statistical informations about an Android device

I write an App and I'd like to get some informations about the Android devices my users are using.
I'd like to know
manufactor
the Android version
and some kind of unique ID
Is that possible without any special permissions? What is the API?
Take a look at the Build object. It will give you some details about the Android build.
Information about the Android version can be found in Build.VERSION
Hope that helps.
I'd like to know the manufactor, the Android version and some kind of
unique ID. Is that possible without any special permissions?
If you wrote 'permission' word in terms of manifest permission then you dont need any special permission for that , because its not something from user must be aware about application access of that data .
and if you would like to know about Build information then brianestey's answer is much clear to that .

Android : Programmatically Factory Reset?

I am having full access to Android system. I have all the super user permission to do all the things from any of my application. I just want to implement one functionality in which I need to reset the device without redirecting user to PRIVACY_SETTINGS. If anyone knows how to achieve that please share with me.
Its kind of urgent. Thanks in advance.
You can use device admin. http://developer.android.com/guide/topics/admin/device-admin.html It allows you to wipe all the data. There's a good sample in API demos.
Programmatically: https://stackoverflow.com/a/11885303/1257591
It shows two ways, one is the implementation mentioned by Mighter and an approach for older devices (android version < 2.2)
ADB: https://stackoverflow.com/a/10829600/1257591
Contains adb commands and an example. Judging from the tag of your question this might be the answer you are looking for.

Mtp-Host Application

Is there any application available in Android Market that used USB/MTP Api's?
tell any information that will be useful for me in making android MTP Application?
I think this might help:
Honeycomb-MTP-sample
It's a sample application that uses MTP to read camera contents.
I think camerabrower also gives you something about MTP/HOST.
