android - How to not get my alarm on its own way? -

-

i'm using alarm manager trigger intentservice every hour. however, alarm gets registered when user runs app. problem when user opens app again makes manager create new service run , if current service running trip on each other because of database connection , dies!

another problem alarm service stops. why? thought alarm should go on every hour no matter what!

at beginning check existing database . if doesn't exist. make database , start alarm. next time app start if found database not start alarm again.
or use saved value use semaphores check value 0 or 1..
rest functionality of alarm manager supposed work
