Opening an Android App Link will cause Android System to Crash - android

I wanted to see if anyone else is running into this issue. I have Android App Links setup for my app and site. Things were working fine, but after I've updated the gradle wrapper and other libraries every time my I try my Android App Link it will cause Android to throw the modal that says...
"Unfortunately, Android System has stopped"
And it will not open my application. However it works when i try to open using the traditional URI scheme deeplink.
Any help will be greatly appreciated. Thank you.

Figured it out.
The issue was that my icon was too big for the device to render on the modal that pops up. Changing that to an appropriate size fixed it.

App isn't installed on your device error in very first program

There seem to be too many bugs which have not been properly documented, regarding android studio. I am trying to run a basic Hello world app, and this error is truly making me give up any more efforts.
What I did:
Open Android studio(also tried running as administrator) and tried to run the default Hello world app on an Android 10 device(Xiaomi). At the start it shows Failed to start monitoring 7D8XXCOJGQQCZLJV(device number). At first I ignored it being a beginner and clicked on the run button. The file was successfully built and the RUN section shows 'Install successfully finished'.
Now for clarity here are some screenshots that will display what happened on my android device after the above steps:
The app seemed to be installed correctly, but whenever I click on the app logo the response I get is really frustrating:
As per the this link I tried to go to the device manager and do some changes, by setting and enabling Xiaomi drivers for Portable devices.
But then windows shows:
If anybody knows how to solve this, please do help me in doing so. It is quite discouraging to experience so many errors, right at the beginning. If somebody could give a working solution then that would really help me in continuing my android journey.
There was just a tiny error that led to this entire problem. This was because I had set the value of android:exported="false" in the main activity, which had to be set to true. Hope that this may help anybody in the future!
set the value of android:exported="true" in the AndroidManifest

Getting an App APK

Hey guys and girls for a the past week I've grown a lot of interest in android studio (even without knowing quite much about it) I decided to create an app that I deemed quite useful. However the app required maps to be integrated in it and I really did not know what I was doing and at one point I started messing with the settings and then all hell broke loose and I kept getting AAPT2 errors and I even tried to fix this issue with the gradle properties line that you add (I forgot the line of code to add). Anyways it still didnt work. However I rembered that I always kept the good version (before I broke everything) of the app on my phone. So when I go in my phone the app is there and it works just fine. Ive tried so many things to get the source code from the app on my phone without any succes. My question is, how can I get the source code back from the working app onto my laptop to continue coding in android studio? If it helps I am using Linux 18.04 LTS and running the newest version of android studio. Thank you for any help from you guys. This means a lot to me.
You can’t get back the ‘source code’ from an already compiled app.
You should consider using some version control platforms like git from the next time

URI is not registred error in andriod studio at build/intermediate/res/merged/debug/menu/menu.xml

I think because of this when I build and luanch an application it is closing immediately. enter image description here
Can I anyone tell me why exactly this is crashing?
Without seeing logcat we cann't know the reason why your application is crashing
Go to Android studio at bottom you will see logcat option, open it then you will see stacktrace it will helps in finding the reason.

VS can not open solution of android application

I can not create or open an android application project. VS tries to open the solution but it only shows a message box with "preparation of solution".
I am a little unsure of what you are asking. What version of VS are you using? What you are trying to open, does it actually work?
Try giving it a little bit of time if it is getting hung up on loading.

Android App Failed To Load On Blackberry Z10

Okay, let me first apologize by saying this is my first post on stackoverflow and haven't been coding that long so this may be a simple error on my part. Also let me thank you ahead of time for trying to help me. So this is basically what is ailing me, I have a app i have coded that is used to set wallpapers on android phones and recently have been submitted to blackberry's appworld.
I have never had any issue with the app until the other day when all of a sudden when i changed the package name to a new one. Note this is of a fresh install of the app. But for some reason the Blackberry Z10 is opening the app for about a second and shows me a black screen for less then a second and then close. However, my eclipse's logcat states otherwise and that it is still loading. Note that I have other apps using the same setup and library as this app and also have recently changed their package names and haven't run into this problem. Also this only happens on Blackberry Phones and doesnt give me this issue on any normal android phones.
Here is my logcat: http://pastebin.com/EzD6eQaU
If you have any idea why this is happening please let me know.
Thank you again,
Dalton
It took a while but i found out what was my issue. Blackberry has a package name character limit of at least 50 characters long. Any more then that and your app wont work on blackberry.
