[Q] Casting/Mirroring but hiding Information - Android Q&A, Help & Troubleshooting

Does anyone know how to go about casting/mirroring your android device to a TV? While you are hiding information?
For example, say I wanted to cast/mirror a custom app from my phone, but I wanted some stuff to only be visible to me from my phone. How exactly would you go about doing this?
(My thought of approaching this)
Is there a way to configure a custom app so it will zoom-in in a specific area? Which only zooms-in on the app from the TV to hide all of the exterior stuff I ONLY want to see from my android device.
Is there a specific software or device you need to use to accomplish this?
I work with Android Studio just in case this helps. I hope I explained it well enough and provided enough information.

[Q] Best way to make our droid kiosk like? (Custom ROM?)

Hi Guys
I've been developing a http based Server Software that uses an android device as a single purpose device.. say an input terminal. So I developed a very simple app just for this input purpose (including some data from sensors on the device). It aslo loads a web view for a little html banner.
So it's really simple and the design is to basically turn an android device into a single purpose hardware... and with that said i really dont need 90% of what's installed and running on android, I dont need complicated launchers, and i DO need to kind of "lock the device down" to my app only (i guess kiosk like?)
I basically need the hardware and the OS to run my app.
if possible make everything as lightweight as possible (again as i dont need most of the android features)
and I would love it if my app can run on top of everything and at every start up (it can even pretend to be the SHELL or OS on top of Android OS, or kind of like that approach)..
So yeh, I'm hoping you guys can give me some advise/suggestions as to how best to approach this? (honestly i'm fairly new to android as a whole)
Things off the top of my head are:
1) Custom ROM like really plain/lightweight w/ lock down features <-- is there even any rom like this? or could i ask someone to code this for me?
2) Root, SuperSU, and xPosed Framework plugins and tweaks ? <-- i've not tried xPosed Framework and Im not sure if it's meant to be, or good for, my purpose.
3) Use an APP that can pretty much make a Kiosk out of the phone, w/ my app running permanently? <-- i've seen one kiosk app www.kioware.com but it's crazy expensive and i guess a bit of an overkill to what i need.. Perhaps there's a cheaper more simple kiosk app you can recommend? or perhaps an opensource project i can tinker with?
Would really appreciate your thoughts on this..
Thank you very much!
A common request
Can anyone direct me to a thread where this issue is resolved? It seems more complicated than it seems at first glance.

Android - root to run one program

How would it be possible to make an android phone run my app on startup and not let the user out of the app unless they use a password
The device is created for our app.
Not sure about from start up, but you can use the screen pinning function in Lollipop or if it's running an older version of Android then you would need to create a kiosk type app.
Good luck!
There are 3 well known 'kiosk' apps available. They are all capable of doing what you want to a greater or lesser degree. (Kioware, Mobilock and Surelock ....others are available). The problem for you is the cost, if you intend to scale up your devices. If you are putting your app on a $20 Chinese tablet, then these apps listed above all want another $15 or so to install, which doubles your costs!
I'm looking at a similar problem, and I think the true answer is a specialist ROM with most of the opsys actually stripped out. Only problem with that is...... that it is WAY beyond my talents and abilities! I would be enormously interested in how you get on (without needing to know your application specifics). Keep in touch?

Is it possible to block apps from being installed on my device by Package Name?

Hello there!
I use a Motorola Moto G6 that's running on Android 9 Pie (Build no. PPS29.118-11-1) and I was wondering if there was a way to block certain apps from being installed on my device by their package name. I want to be able to do this for the same reason I use very strict settings on Digital Wellbeing: self control.
I know that you can install and block apps and I know that you can use parental settings on your phone but that simply won't help in this situation. I'm also aware that an app with these capabilities might not be available. My question isn't if it's possible now or with the utilities currently provided through apps developed for my Android OS; I'm trying to figure out if it's possible to block apps by their Package Name in any way and if it's impossible to make (in theory) an app that can do it.
I'm not sure how it can be done. Can it be done by having an app that reads through an app that's attempting to be installed and generates bricked app directories where it should chuck out the app's resources so it can't be installed? Maybe. Can it be done by cancelling the installation request of an app that has a Package Name matching one inputted into a list on the hypothetical app in question? Not sure. If anyone knows the answer to those two proposals or has their own suggestions, please do your best to answer my post and keep in mind, this has to be done without the phone being rooted.
An additional but important factor: this is about self control. I can easily bring myself to not remove or otherwise disable restrictive measures on my phone, but I'd like to know if I can make it so that you cannot remove a Package Name that has been blocked in the phone no matter the method used in the first part (other than uninstalling the blocker app, of course).

Is there a device and android version that allows complete control of all permissions

Is there a phone/android version that allows someone whos not an Android expert to actually have control over what their phones doing? Or is it just not possible nowadays for a regular person to fully control the info their phone sends?
Sorry if this sounds cynical, it really is a genuine question.
Thank you.
Hi Steve, it sounds like what you need is a rooted phone. Forgive me if you're already familiar with the term, but rooting basically gives you administrator rights over just about everything on your phone, with only a few exceptions depending on which Android version the phone is running. This allows you to do stuff like revoke permissions for apps, block ads, and change how Android looks and behaves.
Do you have a phone in mind already? If not, what's your budget?
questions should be posted in q/a Thread moved please review the rules ( located below)

Thank you for your help. I had a rooted phone, but a friend did it for me. Now I have a S8 active on Pie and from my research the bootloader I have (V5) is not rootable. I'm definitely not well versed in Android though and could be wrong. That's why I was wondering if there was a device that offered full control without the need and rick of rooting. If there's not, could you suggest one that is perhaps the simplest and least risky to root? I don't need top of the line, I don't game or anything and would be fine with getting something used. thanks again!
Luckily, there is a way in stock Android to control permissions! I forgot about it when I was typing my previous response. Here's an overview: https://www.howtogeek.com/355257/can-you-control-specific-permissions-on-android/ Hope that does what you're looking for.
If you want to do more with a rooted phone like block ads, there are some that are easily rootable, like the Google Pixel series. Here are a few options: https://www.androidcentral.com/best-phone-rooting-and-modding I liked the Pixel 2XL I used through my previous job, and I've heard good things about the other Pixels, for what that's worth. I haven't tried the other phones in that link, but the OnePlus phones have an excellent reputation.
There are many other phones that have varying degrees of difficulty for rooting, but I'm not aware of any relatively recent ones not on that list that I'd consider easy to root. I've found that the best approach to finding a new phone is going to GSM Arena's Phone Finder to put on my criteria, then coming back to XDA and searching through the forums to find out whether my prospective phone of choice has root yet. As you've discovered with your S8, some phones just never get there, which is pretty frustrating.
I hope that helps! Holler if you have any other questions.
Well, that's my main issue, you can only control certain permissions there. When I click "all permissions" I can see them all, but not turn them off. It's just a bummer that one has to go thru all this rigmarole to control a device they supposedly own. I was hoping maybe someone made a device that you could control stock, but I guess that was wishful thinking. Thanks again.

You must distinguish between Android OS itself and the apps that run on it: Android OS has no permissions you can invoke/revoke, only hardware/OS specific settings can be made there, but permissions can be granted/withdrawn from an app - if its developer has allowed the latter. To change the permissions of an app basically no rooted Android is required, this is done either via Android->Settings or via a 3rd-party APK editor.
BTW: It exist 3rd-party apps that can show you what apps are sending/receiving data over Internet.
Hint: Use your Android phone without Google.
Is root required to disable hardware?

Newbie to development....

Hello,
I have a programming background but I'm new to android dev. so may I ask:
How difficult would be to implement an app that returns the GPS location of a specific phone and what tool would be the easiest way to make it? Will App Inventor do it? Another tool would be RFO-BASIC. Could someone be kind enough to describe the steps involved?
Reason for this kind of app is a friend of mine who has a 15yo child with health problem and needs to monitor it. I know there are apps in the market but: 1) Most are not free and 2) Does not want to (or can not) get his child's email details to use it for this purpose.... What he can do is take the phone for a while and install an app.
I suggest you check the official website of android development, where there are documents and tutorial for android app & GPS location development.
