For some reason I am unable to connect my Android phone to PC using a USB cable. I have tried everything from changing cable, updating drivers and even factory resetting the phone but nothing works. Consequently I can not debug in Android Studio. Is there any way to debug(using Bluetooth, WiFi or something else) without using a USB cable at all?
PS: Please do not mark this question as duplicate. I have already read answer to similar questions([one of them is this])1 but the solution suggested there involves using USB cable at least once(for initial setting of debugging via Bluetooth/WiFi). Is there any way that let you debug apps without using a USB cable at all?

I have a usb device for transmitting data. the device works perfect in windows OS. I am to use the device in Android 13 the Device acts as Human Interface Device.
I am using Android Emulator for programming. It seems the emulator work only for UI and not for external hardware.
And I achived that in android app, It can able to read that pendrive. When I run that app in Emulator it is not detecting.
Can you suggest how can I make Android emulator detect the usb device.
Thank you for your kind interest.

I want to connect USB device on Emulator.. and need to view that contents.
So, my xbox one controller does not show up in my windows 10 bluetooth pairing. It 100% is not a problem with the controller since it works in both other pcs and my android phone. Somewhere, somehow, its id is forgotten in my bluetooth settings. I have, used bluetooth tools to unpair everything, removed everything xbox related from my device manager, removed the controller from devices and printers, and obviously removed from bluetooth and other devices. Even after deleting the device from
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters\Devices
i still cannot for the life of me connect it to my pc. Any idea how I can delete all my connected ids or something? It used to work until yesterday, when i plugged it and then unplugged it using a usb cable.
Debugging apps on a physical device (in my opinion) is better than using an emulator.
I was wondering if it's possible connect my phone to my computer via Bluetooth (or wirelessly) without a USB connection.
The wire kind of get in the way sometimes.
I have a windows 8.1 based lap top which supports Bluetooth.
I wrote a java based bluetooth server which gets connections from Android.
The issue is, the device sometimes get invisible(or to say not shown) on android devices.
I've tried with other laptops or Android phones, but sometimes it just doesn't get searched.
I think it's not about my java server program. Even if there's a problem with my program, it should at least be shown on the bluetooth search list of other devices.
I found a very crude solution about this issue.
Always running the 'change pc settings(not the exact name)' app of windows 8.1, and going to 'PC, devices' -> Bluetooth makes it always searchable. If I turn this off(I mean the 'change pc settings' app, not turning off bluetooth), the bluetooth cannot be found by other devices.
Why is this happening? My purpose is, bluetooth server must be turned on automatically after boot, but the reliability of the bluetooth device is failing my intention. However, since my crude solution above is temporarily solving my issue, I do not think it's a hardware issue.
So, my question is :
1) Why is this happening? And how can I mend this?
2) How can I run windows metro app through windows shell? If I can't find any other solution about this, I will have to write a batch script to always run the solution thing above.
Going to Change PC Settings>PC and devices>Bluetooth is initiating a Bluetooth device search. As a side effect, the Bluetooth is also made Discoverable (pairing mode). However, this Discoverable setting is temporary, only while the PC is searching for remote Bluetooth devices.
If you wish to keep Bluetooth Discoverable at all times, you need to check the "Allow Bluetooth devices to find this PC" button box, found in Bluetooth Settings. I found Bluetooth settings by right clicking the Bluetooth system icon. Can also be found in Devices and Printers, by right clicking the Bluetooth adapter icon.
I want to know if the developer team which made the emulator have some information to make bluetooth work in the Android emulator, indicate some links about it, if they have some date for release or if they'll make it works in the future.
as far as I know there is no support in the emulator for bluetooth. And I will have to teach android and bluetooth in some classes. And the students will need to code stuff and test (guess it) in the android emulator.
So I came up with a bare-bone reimplementation of the android bluetooth API on top of tcp. You can find it on here on github.
Basically, you run a tcp-server on your machine, and the emulators will connect through it.
Instead of using the classes in the package android.bluetooth, you just need to use the classes in the package dk.itu.android.bluetooth (and other 2 little modifies).
As for now it supports:
switch on/off the "radio"
discovery devices (only other android emulators)
creating bluetooth services
connecting to bluetooth services
It's not much, but until we got some more from the android guys, I guess there is nothing else around.
Hope it'll be useful, cheers!
The documented bluetooth limitation appears inconsistent with the qemu -bt option. So, how is bluetooth enabled in the emulator so the -bt options can be used, or at least to know that bluetooth is supported?
The target/board/.../BoardConfig.mk having "BOARD_HAVE_BLUETOOTH := true" doesn't provide a bluetooth icon or enable bluetooth. So, how do we turn on bluetooth on the android qemu emulator?
What does it mean that bluetooth is not supported given the -bt option for emulating USB devices that were provided in 2008? The post and limitations are outdated.
The functional limitations of the emulator include:
No support for placing or receiving actual phone calls. You can simulate phone calls (placed and received) through the emulator console, however.
No support for USB connections
No support for device-attached headphones
No support for determining network connected state
No support for determining battery charge level and AC charging state
No support for determining SD card insert/eject
No support for Bluetooth
