Android Question startup/services differences in os v6

[sorex]

Hello,

I have written a sound monitoring system that's hanging in the halway where kids with mental handicap are sleeping.

This worked fine for years and now we had 2 phone batteries that had like exploded (not leaked but twice as think) so we decided to replace all 4 phones.

This are cheap Wiko Sunny phones with OS v6 on it.

I have the impression that the service that brings up the app to the front every minute doesn't kick in.
The app also doesn't auto start at phone reboot.

Is there anything different that I need to do to make this working? the other phones where still v2.3.6 and might be less secure on that topic.

With each new version of Android, the OS adds more restrictions on background processes.

The simplest solution is to create a foreground service that runs all the time.

My 50 cts : with Wiko, if I recall correctly, you could try to disable their power saver app. In the past, I had threads constantly failing when it was activated.
And for the auto start, if I recall correctly too, I had to put the app on the internal memory instead of the SD Card (even if the SD card was set as the internal memory).

it's a service that sends info to my server every minute. I'm not using startAt. So that's good I guess?

@lemonisdead : thanks, I'll have a look at that.

I turned off that power management.
The app is on internal memory according to the apps tool.
In that Wiko phone assistent it shows my app under boot uptimze as boot app

but the app still doesn't boot

 

[sorex]

Could it be that it is the launcher that's not executing that bootatstart apps?

 

[lemonisdead]

I don't think so but more the power management app.
Why not trying to register the intent receiver from the manifest for a try ?

AddReceiverText(YourServiceName, <intent-filter>
 <action android:name="android.intent.action.BOOT_COMPLETED"/>
 </intent-filter>)

The service will be killed when the app is in the background.

This is added automatically when you set #StartAtBoot to True.

Make sure not to use the starter service for the #StartAtBoot flag. Use another service and set this services #StartAtBoot to true.

that network service brings up the app to the forground to prevent accidental closure with service killing.

 

[sorex]

Make sure not to use the starter service for the #StartAtBoot flag. Use another service and set this services #StartAtBoot to true.

I don't know what you mean with starter service but this is a regular service. there are 3 of them. network (autoboot), broadcast and receiver.
The last 2 is the streaming stuff started depending if the app is used as broadcaster or receiver.

 

[sorex]

since the app simply doesn't start it doesn't even get to the service part.

 

[Erel]

Start with calling Service.StartForeground to prevent the process to being killed.

This is what i suggested. So you already have it like this.

 

[sorex]

I added a log line but I don't see it appear in the B4A logs either. so it appears to me that the system or launcher simply doesn't start boot apps.

Sub Service_Create
Log("!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!")
wifi.Initialize
EnableWifi_tick
StartActivity(Main)
End Sub

 

[lemonisdead]

launcher simply doesn't start boot apps

Trying if it is the launcher should be simple by installing Google Now Launcher for example

 

[sorex]

I installed Google Now but it still doesn't boot the app

 

[sorex]

Alright! got it working...

You need to mark your app as protected app or it won't boot at startup.

On this model it's...

Settings > Protected Apps > Enable "User defined" switch > enable it for your app
