Android Studio stopped recognizing my Redmi as an Android device - android-studio

I normally use my Redmi 7A to test the applications that I make with Android Studio, but suddenly Android Studio stopped recognizing it as an Android device and only shows it as a USB device, I tried restarting both the pc and the mobile, deactivate and activate the debugging mode, and it should not be a driver problem because until a few days ago I could run the applications perfectly on my device. Additionally I tried to connect two more devices of different brands in debugging mode and it did not recognize them either, someone could tell me what happened with the IDE and how to fix it.An image of what Android Studio shows me

How to run Android Studio emulator on M1 Mac?

I'm having a devil of a time using the Android Emulator on my new M1 Mac. My Android project compiles fine, and I can run it on a hardware device. But I'm not able to run it on the Emulator.
I followed instructions carefully, and set up an arm64-based emulator running API 31. When I press the "Run" button in Android Studio, the emulator opens and boots normally. However, Android Studio is never able to launch my app on it. I see a message "Waiting for all target devices to come online", and that's it.
I have of course tried restarting the emulator, restarting Android Studio, rebooting my computer, and wiping the data from the emulator. I have also made sure that Developer mode is enabled in the emulated Android environment and "USB Debugging" is turned on.
Another suggestion I saw was to un-check "Enable ADB Integration" in Android Studio. This option doesn't exist in my copy of Android Studio, although I did some further research and found that it is now called "Use libusb backend" instead. It is unchecked by default. I tried checking it anyway, and that didn't help.
I'm at a loss as to what to do next. I really need to be able to test my app in the emulator as my inventory of physical devices is fairly limited.
Thanks,
Frank
Download Android Studio Preview, create emulator (API 30 or S), now you can use emulator on both preview or stable Android Studio.

Couldn't start project on Android: Error running adb: adb: device offline {ERROR}

I keep getting this error when trying to start emulator on android. I don't have a device plugged in only attempting to test to see if my new installations of android studio and emulators work, I am using a Mac with the M1 chip. Any help please.
Try reinstalling the android studio as it may be corrupted or change the device and see
Hope this works :)
It could be a number of different things that cause that error. Here are some troubleshooting steps to try:
Reboot the phone
Try a different USB cable, or unplug it and re-plug it back in
Use command line tools to relaunch adb if it gets hung up; try adb kill-server then adb start-server and then adb devices
Reset the USB debugging on the device in the settings; disable it and re-enable it
Try changing transfer modes in the USB debugging (i.e. camera PTP)
Close and restart Android Studio
Android studio emulators are still based on Intel Haxm virtualization software. I'm sure updates to AS are coming but for now you need to download a separate emulator to run an AVD (Android Virtual Device). It's pretty easy to download and install.

Android Studio doesn't recognize Android Devices on MacOS Sierra

I have always been able to get Android Studio to recognize my USB android devices in the past. However, this morning I upgraded to MacOS Sierra. Now, when I plug in an android device android studio doesn't see it. And my phone acts like it is plugged into a wall and not a computer. Usually, when I plug into a computer, I get the an option in the notification/dropdown menu to select a PTP or MTP connection. I am not getting that option.
I'm running Android Studio 2.2.3 and macOS Sierra v10.12 on a Macbook Pro.
I have tried different cables, different android devices, restarting my computer, still no dice.
If I run ./adb devices from the /Library/Android/sdk/platform-tools/ directory then I get nothing but List of devices attached with a blank line underneath.

Android Studio No devices connected

Running windows 7 and I have just downloaded the latest android studio version and started a project and now I'd like to test the application on my device but Android Studio says on the bottom left "No devices connected". I've tried a couple of things such as:
updating my Samsung S6 edge drivers through device manager, which were updated now.
have debugging mode turned on and USB debugging mode on.
ran 'adb devices' command to list devices but none show up.
downloaded new universal adb drivers.
toggled between MTP and PTP modes.
restarted computer/phone/android studio/ adb tens of times.
deleted phones drivers from device manager and installed again.
re-installed android studio.
probably some other small things too that I can't remember right now.
I'm at a loss as of right now, if someone can help me out I would really appreciate it!
