Enable / Disable NFC Using ADB Command

Question

Is there any way to disable / enable NFC through ADB shell commands?

I found one answer here .

What I tried at the link above:

 # Enable NFC service call nfc 5 # Disable NFC service call nfc 4 

but it does not work.

Any help appreciated. Thanks.

Answer 1

In your eclipse DDMS or using logfilter or any runtime log capture tool, you need to get the process id of your NFCService. You can then kill or stop this process by specifying the process ID.

Answer 2

# Disable NFC

nfc 7 service call

Confirmed for Android 8.0

Hooray!

Answer 3

System service method codes may vary by version of Android . Therefore, before calling the service method, look at the AOSP sources.

Below is a summary of NFC allow / block calls prior to Android 5.1.1. Also keep in mind that (in sources)

 int FIRST_CALL_TRANSACTION = 0x00000001 

i.e. equal to 1 .

Android 4.4 - Android 5.1.1

 # Disable NFC service call nfc 5 # Enable NFC service call nfc 6 

Android 4.0.1 - Android 4.3.1

 # Disable NFC service call nfc 4 # Enable NFC service call nfc 5 

Android 2.3.4 - Android 2.3.7

 # Disable NFC service call nfc 18 # Enable NFC service call nfc 19 

Android 2.3.3 :

 # Disable NFC service call nfc 20 # Enable NFC service call nfc 21 

Android 2.3.2 :

 # Disable NFC service call nfc 13 # Enable NFC service call nfc 14

To check the status of the NFC service, use the dumpsys command:

 dumpsys nfc
