Following are some more findings
When application is running fine following message doesn't appear when
service is scheduled
/ActivityManager( 57): Start proc MyService.Test for service
MyService.Test/.MyService: pid=426 uid=10023 gids={3003}
rather a message from very first line Service is printed. But when
application crash is to be started then application seems to be started by
ActivityManager and following message occurs
/ActivityManager( 57): Start proc MyService.Test for service
MyService.Test/.MyService: pid=426 uid=10023 gids={3003}
Why ActivityManager is starting MyService and after that application never
work ? But in normal case why above message is not displayed and scheduled
service works properly?
