Android Question [solved] Restarting Activity if crashed (using a service)

Asim A Baki · Mar 27, 2014

How I suppress the OS crash message and restart the activity if it is crashed?
I think it must be from the service, but how to do it?

Asim A Baki · Mar 27, 2014

Vitamio Bundle crashes the application with some cases

Erel · Mar 27, 2014

It depends on how it crashes. Can you put a Try / Catch block to catch this error?

Asim A Baki · Mar 27, 2014

Tried but no error caught, please also note that the service starting my application doesn't wait until activity stop

B4X:

StartActivity (i)

so the exception handler will not work in the background process

Erel · Mar 27, 2014

This means that the whole process crashes. You can add a sticky service:
Creating a sticky service - long running background tasks

It will be restarted after the crash (unless it crashes several times in a row). You can then restart the app from this service.

What are the error messages or last log messages?

Asim A Baki · Mar 27, 2014

What if the activity only is crashed, the service is still running
Can I make a check if the main activity is not running restart it?

There is no message, only the last started sub name
there is no crash errors

eps · Mar 27, 2014

There _must_ be log messages - trace / debug and then unfilter the logs. If there aren't you can put some in...

and the unfiltered log?

that's all the log without filter

eps · Mar 27, 2014

Then I think you'll need to start putting some log statements of your own in place.

Asim A Baki · Mar 27, 2014

Yes it already has on error logs but nothing fired when crash occur, silent crash or OS crash message
I made the STIKY service method, it solved the issue somehow but not totally, some crashes with message from the OS can't be automatically restarted

Erel · Mar 27, 2014

The UI Cloud is implemented with a server and 10 real devices that run a custom version of the designer. They can run for months without any administration.

In addition to the designer there is another app that calls Service.StartForeground. This app calls StartActivity with the designer main activity every minute. If the designer is active then nothing happens. If the designer has crashed for some reason the designer is restarted.

For this error it looks like you ran out of memory.. I would use MemoryManager to see what the memory usage of your App is and try to optimise the memory use, then it will crash a lot less.

You can also use the LargeHeap manifest setting as well. http://www.b4x.com/android/forum/threads/using-android-largeheap.14903/#post-120731

Great thanks

B4X:

SetApplicationAttribute(android:largeHeap,"true")

has successfully did the job and stopped crashes
Thanks again
