Android Question PhoneWakeState And Timer In DeepSleep

[Hakanunver]

Hi B4A, I try to make an app which uses Xmpp with asmack library.
I can connet to server, get or send message. App is stable with xmpp.

When phone/cpu goes deep sleep. I can get messages and run media player to make alarm but i can't open my application with;

XmppService:

Sub Process_Globals
    Dim p As PhoneWakeState
End Sub

Sub OpenApp
    Try
        If main_status = False Then
            StartActivity(Panel)
            p.KeepAlive(True)
        End If
    Catch
        Log(LastException)
    End Try
End Sub

Sub pingBaglantiHatasi(varmi As Boolean)
    If varmi = True Then
    OpenApp
    sescal
    End If
End Sub

I run this code in my XmppService Module and cannot open app

My another problem is I wants to ping my server to learn is it achievable when device in deep sleep. So i tried

XmppServerPing Servce Module :

Sub Service_Start (StartingIntent As Intent)
    XmppService.objXmpp.BaglantiVarMi
    'StartServiceAt("", DateTime.Now+15*1000, True)
    'StartServiceAtExact("",DateTime.Now+15*1000,True)
    'SetExactAndAllowWhileIdle(DateTime.Now+15*1000,"XmppServerPing")
    SetAlarm(DateTime.Now+30*1000)
End Sub

'Sub SetExactAndAllowWhileIdle (Time As Long, ServiceName As String)
'    Dim p As Phone
'    If p.SdkVersion < 23 Then
'        StartServiceAtExact(ServiceName, Time, True)
'    Else
'        Dim in As Intent
'        in.Initialize("", "")
'        in.SetComponent(Application.PackageName & "/." &  ServiceName.ToLowerCase)
'        Dim jin As JavaObject = in
'        jin.RunMethod("setAction", Array(Null))
'        Dim ctxt As JavaObject
'        ctxt.InitializeContext
'        Dim am As JavaObject = ctxt.RunMethod("getSystemService", Array("alarm"))
'        Dim pi As JavaObject
'        pi = pi.InitializeStatic("android.app.PendingIntent").RunMethod("getService", _
'  Array(ctxt, 1, in, 134217728))
'        am.RunMethod("setExactAndAllowWhileIdle", Array(0, Time, pi))
'    End If
'End Sub

Sub SetAlarm(timeToAlarm As Long)
    'declare variable for java object
    Dim srvAt As JavaObject
    'call the function
    srvAt.InitializeContext
    srvAt.RunMethod("StartServiceAtExactWhileIdle", Array(timeToAlarm, True))
End Sub


#If JAVA
//import android.app.Service;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.PowerManager;

public void StartServiceAtExactWhileIdle(Long time, Boolean wakeUp){
  AlarmManager alMan = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
  Intent intent = new Intent(this.getApplicationContext(), this.getClass());
  PendingIntent penInt = PendingIntent.getService(this.getApplicationContext(), 1, intent, 134217728);
  alMan.setExactAndAllowWhileIdle(wakeUp?AlarmManager.RTC_WAKEUP:AlarmManager.RTC, time, penInt);
}
#End If

XmppService.objXmpp.BaglantiVarMi is my xmpp libraries function it pings to server and return true or false to my
pingBaglantiHatasi function in XmppService

Where i m wrong or what may i do ? Thanks.

This line is wrong:
StartActivity(Panel)

It should be the activity module name instead of Panel.

 

[Hakanunver]

I have Activity module called Panel

 

[Erel]

I have Activity module called Panel

This can easily cause all kinds of problems. It is better to change its name.

 

[Hakanunver]

I changed module name but Result is the same.

 

[Erel]

Add some log messages to make sure that the code actually runs and main_status is false.

PhoneWakeState.KeepAlive(True) is supposed to turn the screen on. Do you see it?

 

[Hakanunver]

I m sure about main_status = false (from my log.txt)

 

[Erel]

There are two possible issues:
- The code doesn't run at all.
- The code runs but PhoneWakeState fails to turn on the screen.

How are you starting the service? With StartServiceAt?

 

[Hakanunver]

I start my XmppService with StartService at the opening of the app and i use;

Service.StartForeground(1, Notification)

at Service_Start

XmppService:

Sub Service_Create
        Logger.Initialize(File.DirDefaultExternal , "TheLogFile" )
        If Notification.IsInitialized = False Then
            Notification.Initialize
            Notification.Icon = "icon"
            Notification.SetInfo("My Service", "My Service", Main)
            Notification.Sound = False
            Notification.Vibrate = False
        End If
        If ph.SdkVersion >= 9 Then
            Dim r As Reflector
            r.Target = r.CreateObject("android.os.StrictMode$ThreadPolicy$Builder")
            r.Target = r.RunMethod("permitAll")
            r.Target = r.RunMethod("build")
            r.RunStaticMethod("android.os.StrictMode", "setThreadPolicy", _
            Array As Object(r.Target), Array As String("android.os.StrictMode$ThreadPolicy"))
        End If
       
        BroadCast.Initialize("BroadcastReceiver")
        BroadCast.addAction("android.net.conn.CONNECTIVITY_CHANGE")
        BroadCast.addAction("")
        BroadCast.SetPriority(2147483647)
        BroadCast.registerReceiver("")

End Sub

Sub Service_Start (StartingIntent As Intent)
    Service.StartForeground(1, Notification)
End Sub

My Service_Create and Service_Start like that
I think XmppService never close.

 

[Erel]

It is possible that your device prevents apps from turning on the screen while the device deep sleeps. You can try to whitelist the app. It might help.

 

[Hakanunver]

I checked before battery optimizations and

Smart battery save is close
Optimization is close
I don t have cleaner app or mobile device management app

My Service doesnt kill some other apps because it takes xmpp messages only thing is about p.keepalive(True)

is it can be about p.RealeseKeepAlive ?

 

[Erel]

Not sure that I understand the question. Phone.KeepAlive is expected to turn on the screen. It is certainly possible that your device doesn't allow it.
