This is the way that I get the bluetooth button commands.

Please, can you tell me how I can give 1º priority to my applicatión?
Or disable the bluetooth events for a specifc application like Android "Music"?

Thank.

Not sure that it is possible. There was an example which I previously wrote for handling the "Call" bluetooth button. However I don't find it right now and it is not really related.

You should create a service.
In the manifest editor you should add:

B4X:

AddReceiverText(serviceName, 
                        <intent-filter android:priority="2147483647">
                                <action android:name="android.intent.action.MEDIA_BUTTON"/>
                        </intent-filter>
)

Service_Start will be called each time that a media button will be pressed.
The button value should be mapped to an extra with the key: android.intent.extra.KEY_EVENT

You should add a service and then add the code I posted to the manifest editor (don't forget to change serviceName to the name of the service you added).

When you press on the Bluetooth button, Service_Start will be called.
You should play with the Intent passed.

Erel,
you said:
"Service_Start will be called each time that a media button will be pressed."
"The button value should be mapped to an extra with the key: android.intent.extra.KEY_EVENT"

Please, can you give me a example how mapped an extra key: android.intent.extra.KEY_EVENT?

Thank,

Manuel

In Service_Start you should get the value from StartingIntent parameter.

B4X:

StartingIntent.GetExtra("android.intent.extra.KEY_EVENT")
