Android Question Broadcaster and Gps questions

ocalle · May 30, 2018

I wanna do an app that check when a jack headbutton is pushed and send a sms with a GPS point.
I used ERELs GPS demo and NJdude Broadcaster Example, but when i enable GPS cant intercept the pushed button,
did know someone how can i set the prioritys? or how can i handle both services?

The button alone works, the gps alone works

Mi code is this

B4X:

Region Module Attributes
    #FullScreen: False
    #IncludeTitle: True
    #ApplicationLabel: Test GPS
    #VersionCode: 1
    #VersionName:
    #SupportedOrientations: unspecified
#End Region

Sub Process_Globals
    Dim  pressTime As Long
        Dim cadena As String
    Public rp As RuntimePermissions
   
End Sub

Sub Globals
    Dim lblLon As Label
    Dim lblLat As Label
    Dim lblSpeed As Label
    Dim lblSatellites As Label
    Private ListView1 As ListView
       

   
   
End Sub

Sub Activity_Create(FirstTime As Boolean)

   

        Activity.LoadLayout("1")
    Log(mod_vars.SpeakerPhoneState)
       
    rp.CheckAndRequest(rp.PERMISSION_SEND_SMS)
   
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)

   
   
   
   
End Sub

Sub Activity_Resume


    If Starter.GPS1.GPSEnabled = False Then
        ToastMessageShow("Please enable the GPS device.", True)
        StartActivity(Starter.GPS1.LocationSettingsIntent) 'Will open the relevant settings screen.
    Else
        Starter.rp.CheckAndRequest(Starter.rp.PERMISSION_ACCESS_FINE_LOCATION)
        Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
        If Result Then CallSubDelayed(Starter, "StartGPS")
    End If
End Sub
   

Sub Activity_Pause (UserClosed As Boolean)
'    Dim Sms1 As PhoneSms
'    Log("cadena en sms  enviando sms ")
'    Log(cadena)
   
   
'  
   
    CallSubDelayed(Starter, "StopGPS")
   
End Sub

Public Sub GpsStatus (Satellites As List)
    Dim sb As StringBuilder
    sb.Initialize
    sb.Append("Satellites:").Append(CRLF)
    For i = 0 To Satellites.Size - 1
        Dim Satellite As GPSSatellite = Satellites.Get(i)
        sb.Append(CRLF).Append(Satellite.Prn).Append($" $1.2{Satellite.Snr}"$).Append(" ").Append(Satellite.UsedInFix)
        sb.Append(" ").Append($" $1.2{Satellite.Azimuth}"$).Append($" $1.2{Satellite.Elevation}"$)
    Next
    lblSatellites.Text = sb.ToString
End Sub

Public Sub LocationChanged(Location1 As Location)
    lblLat.Text = "Lat = " & Location1.ConvertToMinutes(Location1.Latitude)
    lblLon.Text = "Lon = " & Location1.ConvertToMinutes(Location1.Longitude)
    lblSpeed.Text = $"Speed = $1.2{Location1.Speed} m/s "$
    cadena=Location1.Latitude&","&Location1.Longitude
   

End Sub

Sub add_intent(i As Intent )
   
    ListView1.AddSingleLine(i.Action)
    ListView1.AddSingleLine(i.ExtrasToString)
   
End Sub

Sub Activity_PermissionResult (Permission As String, Result As Boolean)
    If Permission = rp.PERMISSION_ACCESS_FINE_LOCATION Then
    Log("Permisos concedidos!!!")
   
    End If
   
    StartService("Receiver")
    Log("arranco el service")
   
   
   
End Sub

And on Starter

B4X:

Region  Service Attributes
    #StartAtBoot: False
    #ExcludeFromLibrary: True
#End Region

Sub Process_Globals
    Public rp As RuntimePermissions
    Public GPS1 As GPS
    Private gpsStarted As Boolean
    ' del broadcaster receiver



    Private gpsStarted As Boolean
    Public rp As RuntimePermissions
    Public GPS1 As GPS
   
   
   
End Sub

Sub Service_Create

   

   
   
GPS1.Initialize("GPS")
   
   
End Sub


Public Sub StartGps
    If gpsStarted = False Then
        GPS1.Start(0, 0)
        gpsStarted = True
    End If
End Sub

Public Sub StopGps
    If gpsStarted Then
        GPS1.Stop
        gpsStarted = False
    End If
End Sub

Sub GPS_LocationChanged (Location1 As Location)
    CallSub2(Main, "LocationChanged", Location1)
End Sub


Sub GPS_GpsStatus (Satellites As List)
    CallSub2(Main, "GpsStatus", Satellites)
End Sub

Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
    Return True
End Sub

Sub Service_Destroy
    StopGps

End Sub

And in mod_var code

B4X:

'Code module
'Subs in this code module will be accessible from all modules.
Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
   
    Dim LastStarterMessage As String
    Dim HeadSetState As Int = -1
    Dim SpeakerPhoneState As Boolean = False
    Dim SpeakerPhoneRouted As Boolean = False

   

End Sub

On receiver activity

B4X:

#Region  Activity Attributes
    #FullScreen: False
    #IncludeTitle: True
#End Region

#Region Module Attributes
'´'    #StartAtBoot: False
#End Region

'Service module
Sub globals
    Private v As PhoneVibrate
   
End Sub



Sub Process_Globals

    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
   
    Dim Broadcast As BroadCastReceiver
 
End Sub

Sub Service_Create

    Broadcast.Initialize("BroadcastReceiver")
    Log(Broadcast.isOrderedBroadcast)
   
   
End Sub

Sub Service_Start(StartingIntent As Intent)

    Broadcast.SetPriority(2147483647)
    Broadcast.registerReceiver("android.intent.action.MEDIA_BUTTON")
   
   
    StartingIntent.PutExtra("state", 1)
   
   
    Log("broad:"&Broadcast.isRegistered)
   
   

   
    Broadcast.registerReceiver("")
   

   
   
   

End Sub

Sub Service_Destroy

End Sub

1. It is a mistake to use the starter service to receive broadcast messages. Use a different service.

2. You should add the intent filter like this:

B4X:

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