Use a static intent filter: http://www.b4x.com/android/forum/threads/intercept-volume-button-press.28179/#post-163378

Thks, Erel. But,.. its not working for me. I need to intercept button in service.

 

[Erel]

This code is actually working with services, not activities.

 

[stari]

I try with this code:

'Service module

Sub Process_Globals

       Dim Broadcast As BroadCastReceiver

End Sub

Sub Service_Create
   
    Log("Created Service")
       
   
End Sub

Sub Service_Start(StartingIntent As Intent)
   
      
   
Dim prevVol As Int
Dim curVol As Int
Dim volType As Int

If (StartingIntent.HasExtra("android.media.EXTRA_PREV_VOLUME_STREAM_VALUE") OR StartingIntent.HasExtra("android.media.EXTRA_VOLUME_STREAM_VALUE") OR StartingIntent.Action = "android.media.VOLUME_CHANGED_ACTION") Then
      'prevVol = StartingIntent.GetExtra("android.media.EXTRA_PREV_VOLUME_STREAM_VALUE")
      'curVol = StartingIntent.GetExtra("android.media.EXTRA_VOLUME_STREAM_VALUE")
      'volType = StartingIntent.GetExtra("android.media.EXTRA_VOLUME_STREAM_TYPE")

      Log("OK, received")
End If

     If (StartingIntent.HasExtra("android.intent.ACTION_MEDIA_BUTTON")) Then
        Log("OK, received")
    End If
   
    Log("OK, Service started " & StartingIntent)
End Sub

Sub BroadcastReceiver_OnReceive(Action As String, Extras As Object)
    ToastMessageShow(Action,False)
    Log(Action)
       
End Sub

Sub Service_Destroy

End Sub

Not working. From Activity i can read MEDIA BUTTON as "79". What i make wrong ?

Have you added the manifest editor code?

Add Log(StartingIntent) to check whether an intent was received.

My Manifest looks so:

AddManifestText(
<uses-sdk android:minSdkVersion="4" />
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
AddPermission(android.permission.RECEIVE_SMS)

AddReceiverText(Receiver,
<intent-filter>
    <action android:name="net.work.box.controller.receivers.RemoteControlReceiver" />
</intent-filter>)

AddReceiverText(Receiver,
<intent-filter>
    <action android:name="android.intenet.AUDIO_BECOMING_NOISY" />
</intent-filter>)

AddReceiverText(Receiver,
<intent-filter>
    <action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>)
 
AddReceiverText(Receiver, <intent-filter>
   <action android:name="android.media.VOLUME_CHANGED_ACTION" />
    </intent-filter>)

'End of default text.

I receive, when Headphones are pluged/unpluged, but no action if the button is pressed.
Also i have Log(StaringIntenet). Nothing recieved, when button is pressed.
Java example i found here:
http://stackoverflow.com/questions/...cept-button-presses-on-the-headset-in-android

The volume changed action is not an internal intent used by Android. It can break in the future.

From the source code documentation it seems like it only handles local volume changes and not remote changes.

Hi, thks Erel. But i still don't know, how to recieve if button is pressed or not. Like in this application: https://play.google.com/store/apps/details?id=com.ligq.ikey&hl=en. Any suggestions will be welcome.

 

[stari]

I'm not familiar with Eclipse (sory) so i can't convert Java code to B4A. For example, this: http://stackoverflow.com/questions/...e-click-in-htc-phones-with-broadcast-receiver
Can everybody make this ??

 

[Erel]

The solution in this link is the same as the one you implemented. Just add androidriority="2147483647" to the intent filter.

OK, all working OK. My mistake was, that i have tested on my Samsung Galaxy Tab. But, on tablets this don't work. Thks Erel for cooperation.

Hello, mr. Erel. all OK, only now i wish to close application and i wish, that static intent is no more active. I can't find solution, only uninstall was helpful. Any sugestion ?

 

[Erel]

Static intents cannot be removed. However you can decide in the service what you want to do. You can for example use IsPaused(Main) and if it is paused don't do anything.
