Android：如何将值从一个广播接收器传递到另一个？

Question

i have this broadcastreceiver that executes some code from time to time and triggers itself again by setting a timer (alarmmanager). the result of the calculations is an integer value, which should be used as input for the next time the algorithm is executed. therefore, i need to store this value.

i don't want to do this with SQLite as this would produce an enormous overhead - but what are the alternatives? manage this via shared preferences? store it within files?

any good ideas?

Answer 1

Carry the data around in the PendingIntent you specify to the AlarmManager. However, instead of a repeating alarm, you might need to set a new alarm each time.

Answer 2

I would probably put a broadcast pending intent into the alarm manager, and create that pending intent with an Intent that stores the int value you want to carry over. You would create the pending intent with PendingIntent.getBroadcast() , with the data intent as an argument. Your receiver would receive this intent and get the int value out of it.
