Do you guys know of an Android emulator that supports Bluetooth?
If none, then are there any that can use a Bluetooth USB dongle?
Android emulator does not have bluetooth capabilities, as mentioned in the SDK's docs and several other places
Refer to this documentation: https://developer.android.com/studio/run/emulator#starting

Quick question. I can't seem to find this in the Android docs, so I don't think it is possible, but is it possible to have an Android 4.3 device (in my case, a Nexus 4) behave as a Bluetooth peripheral? I know iOS supports both peripheral and central, but it seems like Android only supports central.
I'd like to connect an Android device to a Mac using Bluetooth LE, but since OS X doesn't support peripheral mode and it looks like Android doesn't either, I might have to go with Bluetooth 2 or another communication method.
Unfortunately there is no way for Android devices to act as a peripheral. He can creates GATT servers, services and charachteristics but there is no way to make the advertising.

The phone supports the central role;
I'm waiting for this feature too, but it seems we have to wait for next Android releases.
Yeah, Android 4.3 does not support peripheral mode. I started a feature request on the Android Open Source Project website. If you also want to see this feature, add a comment or star the post. I think they will get around to it eventually, but it is good to let them know that this is a feature that developers are looking for.

issue: 59693
In API level 4, 4.1,4.2,4.3 its not possible.
Android lollipop API version 5.0.X sdk supports peripheral mode in BLE however this feature is chipset dependent (Phones).
android phones with Broadcom Bluetooth solution already supports it
If you have a Nexus 5 you can install Android L there and try it, I just did it few months ago, Android L has support to act as a peripheral.
I am looking to connect the ACS ACR122 to an Android tablet via USB using their SDK. This part works and I am able to read Mifare NFC cards.
The problem:
I am unable to read NFC smartphones like the Galaxy S3 or Nexus S when I tap against the ACR122.
When looking at what ACS provided it seems they left out of the Android SDK peer-to-peer communication support.
Does anyone know of a solution, workaround or alternative. I am trying to enable my tablet to be able to read from an NFC smartphone.
Any help would be most appreciated.
Does anyone know the best way to detect Bluetooth LE advertisements on a Android device? I need to only retrieve the service UUID and RSSI value from the advertisement packet, I don't need to connect with the device--If this makes a difference. Do I need to use one of the vendor specific Bluetooth API's like Broadcom for a device that contains a Broadcom bluetooth module?
As of Android version 4.2, the Broadcom stack has been integrated into Android and will work out of the box. Prior to that you needed to run another stack to give BLE access, as stock Android had no APIs.
As of SDK 18 Android now has APIs for this. However, in my testing they do not work properly on the Nexus 4 with 4.3.
See documentation here:

I am involved in a Android Project that connects the sensor using Bluetooth 4.0. AFAIK android didn't support Bluetooth 4.0. I tried with my laptop bluetooth 4.0. I tried with Broadcom using this. Later i came to know my Laptop Bluetooth 4.0 is Atheros Bluetooth 4.0 and later i searched for Atheros Bluetooth 4.0 API using android mobiles and tablets. I saw Qualcomm having Bluetooth 4.0 tablet. I want to know, is Atheros giving API for Bluetooth 4.0 for Android SDK.
Finally, long way of search, i found that up to today(23/12/12), Atheros not giving Bluetooth API for developers. But they are providing other API's for Audio, Camera, Device Info and Sensor(mobile shake). So, can't try on laptop also. Dgel comment and link helped me a lot and made me, come to the conclusion.
Android Bluetooth (and other) API's are not specific to the hardware (or software stack).
They are generic and fairly high-level, and Yes they include Bluetooth 4.0.
The actually support for BT 4 depends on the device. Recent Nexus devices support BT4 (both in hardware and in software) as long as they have the Android 4.2 update.
If you root your device you can get to the 'raw' vendor API's, but I don't know what that looks like for BT4, or wheteher any of that is published. In most cases that is Broadcom based, not Atheros.
EDIT:
I just saw this:
http://code.google.com/p/broadcom-ble/
I'm not familiar with this, but I suspect that it was just a stop gap measure before BT4 was added to the official Android API in 4.1.
I am new to Android Platform and I Like to know whether it is possile for an Android device(App) to communicate with Linux system via USB port for 2 way communication . If yes how it can be done . Thanks for your help
USB support is limited in Android currently and only available on > 3.0. Look at the online developer's docs.
