Re: [android-developers] Re: Why my service in Broadcast Receiver gone in seconds.

[Kai Zhang]

Hello,
 The broadcast receiver and service are in the same process.I guest it
is because the mobile rom is modified by the mobile manufacturer.When I
request location in the back ground.The service can not last for long.When
I change my app to another mobile the service works well.Thanks for your
reply.

Thanks,
zhangkai

[android-developers] Re: Why my service in Broadcast Receiver gone in seconds.

['Indicator Veritatis' via Android Developers]

Hi, Kai-

We cannot tell from what you posted what is going on. Please take a look at 
how and when you create the Application, the BroadcastReceiver and the 
Service. Are they all in the same process? Recall that, for example, if you 
create the BroadcastReceiver using the  tag in the Manifest, if 
you specify no flags, it defaults to running in the same process as the 
Application 
(http://developer.android.com/reference/android/R.styleable.html#AndroidManifestReceiver_process).

But if, for example, the process 'hosting' the BroadcastReceiver has no 
other component, then when the BroadcastReceiver is done, the OS will 
aggressively kill the hosting process.

The simplest approach is to use the same process for all three: 
Application, Service & BroadcastReceiver. Then the process will stick 
around until all three are backgrounded or killed (except under "conditions 
of extreme memory pressure"). 
See http://developer.android.com/guide/topics/processes/process-lifecycle.html 
for details on what is liable to be killed under what circumstances.
