Apps Disable autorestart from OS

[cozsmin]

Hello

I have an :

Sony Xperia D2005
Android 4.3
Kernel 3.4.0-perf (administrator@ubuntu-scm03.arimacomm.com.tw) (gcc version 4.7 (GCC) )
compile number : 20.0.A.1.8

Before posting here i visited the Sony's page regarding this problem , but i read that i does not always work , I did restore to factory settings and it still reappears

I have sysadmin knowledge-base and I am able to "ad"b trhu the OS.
I can see that the processes like "com.company.program" are all ran by "/system/bin/app_process" , and under different users like :
radio system u0_a109 u0_a115 u0_a128 u0_a130 u0_a139 u0_a143 u0_a144 u0_a154 u0_a158 u0_a16 u0_a22 u0_a23 u0_a37 u0_a39 u0_a44 u0_a57 u0_i0

Before i start and taking away all rigths of those users , i believe there bust be a nicer way to stop them from auto-restarting the OS
So basically even if an app would ask 1st before restart , it should still not be able to
The only way to restart is forced way

Hey @cozsmin, welcome to AF!

Couple of questions / comments for you:

1. Is your device rooted?

2. Are you trying to do something programmatically here (I see you posted in our app development area...)

3. Yes, the app_process program starts-up the Android applications and each runs under it's own user-id (uid) and $HOME folder (/data/data/<packagename> -- typically only viewable by the app itself or a root user or using the run-as command)

Apps that have a service component will indeed restart themselves--that's what they do and the function that they serve.

Hello @scary_alien

1. It was rooted before , but after factory reset it was nomore

2. Not quite , I am not trying to develop a new application , just to change the way the system behaves

"Apps that have a service component will indeed restart themselves--that's what they do and the function that they serve."
Are you saying that apps that need to restart , should be able to restart your phone EVEN if you are in course of a very IMPORTANT conference call ?

@coszmin, I may have previously misunderstood what you're saying / asking...are you saying that you believe that one (or more) apps are restarting your device, not simply the app itself?

Yes @scary_alien , since it does not happen on all Androids OS-es , i am tempted to think it is the way the system is configured from factory by Sony , i am also curious if not somehow some component updated itself and it need restart , but it does it without asking .
I know linux does not usually restart itself
Actually from surfing more topics regarding the issue , it looks that firmware or bad drivers are causing this issue , where a kernel driver would restart the OS since it is not working anymore

Hip hip hurray Sony

Pretty bad design if the something can restart the entire system without asking the user. I thought that level of crap system behaviour was limited to Windows O/S.

Yeah, I'd be shocked if an otherwise non root-capable app would be able to explicitly restart the O/S, so I'd lean towards some deeper issue you've got going on.

If you're able to consistently recreate this behavior, you could likely capture a logcat which might tell you what offending component/resource is causing or involved in the crash.
