Android Question How to start B4A app when android box is restarted?

[cenyu]

Hello,
I have simple task but can't accomlish it.

I have H96 Android box and write small B4A app that must start automaticly when android box lose his power - restart.
I try to set my app as launcher - not work!
Now i try add receiver and get android.intent.action.BOOT_COMPLETED, then start Main activity - not work!
This is my simple project. Can someone help me with this?

I read that Android boxes have a setting that allows them to start apps on restart, but I can't find one.


This is my code:

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

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Service_Create
    'This is the program entry point.
    'This is a good place to load resources that are not specific to a single activity.

End Sub

Sub Service_Start (StartingIntent As Intent)
    Service.StopAutomaticForeground 'Starter service can start in the foreground state in some edge cases.
    Log("BootService started")
   
    StartActivity(Main)
 
    StopService("")
End Sub

Sub Service_TaskRemoved
    'This event will be raised when the user removes the app from the recent apps list.
End Sub

'Return true to allow the OS default exceptions handler to handle the uncaught exception.
Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
    Return True
End Sub

Sub Service_Destroy

End Sub

Sub Process_Globals
 
End Sub

'Called when an intent is received.
'Do not assume that anything else, including the starter service, has run before this method.
Private Sub Receiver_Receive (FirstTime As Boolean, StartingIntent As Intent)
    ' Стартираме Main Activity при BOOT_COMPLETED
    If StartingIntent.IsInitialized Then
        If StartingIntent.Action = "android.intent.action.BOOT_COMPLETED" Then
            Log("BOOT_COMPLETED received -> starting Main Activity")
         
         
             StartService(Starter)
        Else
            Log(StartingIntent & " -> detected")
        End If
    End If
End Sub

Also i have this lines into manifest:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="35"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.


AddPermission(android.permission.RECEIVE_BOOT_COMPLETED)
AddReceiverText(MyReceiver, <intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>)

Now i try add receiver and get android.intent.action.BOOT_COMPLETED, then start Main activity - not work!

Starting an activity from a receiver requires the special permission: https://www.b4x.com/android/forum/threads/draw-on-top-of-other-apps-permission.90513/#content

Start with something simple, show a notification from the receiver to see that the receiver has actually started.
