Android Studio connection to a physical device

I connect my phone Realme 6s (RMX2002) to my device and the USB debugging is enabled.
Android Studio recognized & connected but doesn't show the app project in flutter like in the photo
So, any suggestions to figure this out?
You need to check your USB cable. They are in two types, one of which only supports phone charging.
I can't quite understand what you're asking here, but according to your photo, no device is selected to debug on.
My advice is to (save) =) and restart Android Studio. Make sure that the RSA fingerprint for your computer is accepted on the phone. Try restarting your phone and reconnecting. Double check that USB debugging is enabled.
I cannot tell what is really going on, it may be an issue with the ADB. Check your Event Log to make sure the ADB debug bridge started successfully.
If you simply try to run your app on an emulator, issues of this kind will be promptly visible.
If you can ascertain that it is not an issue with ADB, Android Studio, or your phone, it is probably a driver issue with your computer, if you are on Windows.
Try this link: https://www.thecustomdroid.com/oppo-realme-usb-drivers/ to install the USB drivers for your computer.
Cheers!
I a had also problem with USB debugging and it was the cable's fault.
An alternative option is to use wireless debugging. A step-by-step guide for Android studio can be found here: https://link.medium.com/UQJWZrfFqob

Android studio not recognizing my device

I know this question may sound like a reiteration of all the other similar ones, but unfortunately none of the other solutions are working.
Problems:
1.ADB doesnt show my nexus 7 (4.4.2) in devices connected.
2.When I go to search drivers from a lsit there is no Google Inc or Android there.
Any solutions would be greatly appreciated
There are many ways you can try:
Install universal USB Driver
Enable USB Debugging
Connect your phone as camera MTP
If this doesnt work for you, add some information what you tried!

Android Tablet device can't connect PC

I have an android tablet "Galaxy Tab 10.1" and need to connect to my pc to debug but it even doesnt show up on Device Manager when I plug the cable. I saw many solutions and tried it, like:
Downloaded samsung usb driver from here:
http://www.samsung.com/us/support/owners/product/GT-P7510MAYXAB
Also in settings USB debugging is enabled.
But there is still no change! Is there any suggestion?? Thanks in advance!
Go to Settings->Select Storage->Click on the three dots->Usb Computer Connection->Experiment with either MTP or Camera. For my phone it works only with Camera mode.
Well, I changed the cable, reinstalled the drivers and worked :)
After you plugged in try to shutdown and then power on the tablet whilst connected. It solved my issue. Hope this helps!!
You could try turning USB debugging off. Also, is there maybe a setting to change the USB mode in settings? Most Android devices have one somewhere.
I've seen this quite a bit, and it seems that happens when the Samsung connector on the bottom of the device is not properly seated. Remove and firmly re-connect has solved the issue a few times for me.
Disconnecting & rebooting the device, run "adb kill-server", reconnect device, run "adb devices" - seems to solve a good few issues also.
Hi There i got a Simple Solution to share.
1st step: Dont connect your android tablet or phone on the computer in this time. :)

Okay Android made this much harder than it needs to be (as usual).
I fought this for two days and finally found a way to turn USB sharing on on the tablet. I loaded the drivers to the computer and it recognized the device but would not read it. The solution was to go to settings, storage and then ignore everything in the storage box. In the top left corner a USB symbol will appear very small next to the sd card logo (if one is mounted) Long Press and drag that down to open a message box. There will be an option to turn on USB sharing.

Android tablet USB Host mode yes or no?

I trying to make a android App, that uses an usb device that need the tablet to be in HOST mode, so it can get power from the tablet. For some odd reason, this only happens every other time I restart the tablet and only if I have the power jack inserted.
So The solution I'm trying to make, is to find out after a reboot if the tablet is in USB Host mode and if not, then reboot automatically.
The tablets are rooted, so superadmin access is no problem and my reboot code is working fine, just can't seem to find anything that says how I can detect Host mode, can anyone share this knowledge with me?
Thanks in advance
Peter
releaseInterface() and close() closes the connection and stuff. I think then you should be able to getDeviceList() or soemthing.
I can't be too sure, since I used slickdev library to connect to my serial device, but this answer is based on data of this page:
