I am using an app on android
I have confirmed that :
if I clear the app data or even reinstall the app from google play, the app does have a specific behavior
if I install the app on a completely new device (I'm actually using bluestack android emulator), the app does have a different behavior
=> hence, what is the data specific to an android install an app can access? how can I change this data without reinstalling the entire os?

Recently, I tried to build an empty activity app using Android Studio for some poc purposes. I connected the app to a physical device through USB. When running the app, it is working on the device just fine except that it does not save the app to the device.
Whereas when I created the app using basic activity and run in the device, it saves the app on my device's screen and installed it into the memory.
Does anybody know the reason and solution for this?
FYR, I am using Huawei VOG-L29 as the device for testing.
You missed the app in the device somehow. The template you use to create the initial project doesn't matter- its not part of the final build. Android Studio doesn't even remember it once it's done generating the initial files. When you upload an app to the device, it will be saved to internal storage and should appear in settings.
I am currently deploying a web app to my own physical Xiaomi Mi Note 10 device with Android Studio, built with capacitor. But everytime i install a new version to my phone, it reverts back an old save state, including old LocalStorage values in Android WebView.
I already wiped out data of the app manually and even uninstalled it, but still, with every new installation via USB the old save state gets restored. I restarted my Android phone and Mac device which im using, still this happens. Any ideas?
Thanks in advance for your suggestions!!
I created a simple Xamarin ANDROID App. I set up my phone to development mode and deployed my app to the phone via USB.
The app continues to work on the phone as a regular app.
I then created a Xamarin MOBILE App which was more complex. I deployed it to my android phone via Visual Studio debug mode as with my previous app and it ran perfectly. But when I attempt to run the app directly from my phone, it won’t run. The first screen partially loads without anything on it and then disappears. My phone puts a message up saying that my app keeps stopping and would I like to close the app. I make use of a file placed in Assets. Might this be an issue when not debugging from the computer?
Might there be a difference between deploying a xamarin android app and a xamarin mobile app.
A minor thing is that it has added the name ‘.droid’ to the name of my app which I would like to get rid of.
I am new to deploying apps to a phone
I have solved it thanks to your helpful prompts.
I looked at the error logs and the error was ‘FATAL’ in a mono dll. This was indirectly helpful in that I knew it wasn’t the logic in my code.
I also made the discovery that running my app directly in the emulator also failed in the same manner as on my phone. I also ruled out that it might be an issue with transferring an asset -a file the my app uses- as I bypassed using the asset.
(Running my app via visual studio in both the emulator and my phone worked perfectly.)
I then decided to re-house my forms and classes in a new template as I suspected it was corruption in some xml configuration setting that didn’t bother Visual Studio. This worked great and the app now runs stand alone on the phone (and emulator).
When i used my mobile for testing of android application. I used to run application directly from android studio. now the app is not getting uninstalled, if I am trying to uninstall the app so how i can know ?
After you have ran the app on the phone from Android Studio once it will remain installed and you can launch it again directly from the phone without Android Studio, likewise when you want to remove it just drag move the icon to the trashcan (or uninstall icon) as you would remove any other app.
I think this is how it is designed to work.
I am new to android app development. I want to create an intent to launch Skype. In order to test this, I assume that the emulator must have Skype already installed.
I tried to launch the play store on the emulator to get the Skype App. But the Google Playstore, when launched on emulator it complains that there is no wifi or data connection.
How can I get the emulator to connect to the host wifi(Wifi which the laptop is connected to?)?
Is there a another way to get Skype app on emulator without playstore?
Thank you
Assuming that you're using the latest Android Studio and Emulator, you could get the Skype application APK file from other sites and drag it onto the emulator for it install the application.
However I do suggest as #CommonsWare stated, use a physical Android Device instead of an emulator as some (probably most) apps won't work correctly due to Google Play Services being missing. You could try the images in the Android SDK that contain part of the Google Play Services within them, it's worth a shot but not something to rely on for the long run.
