Answer 1

I've successfully changed the minimum AlarmManager interval from 1 minute to 30 seconds.

On your device copy /system/framework/services.jar to your computer. Extract classes.dex from it, open with Winrar for example.

 

Download baksmali

java -jar baksmali.jar -o extractfolder classes.dex

edit extractfolder\com\android\server\AlarmManagerService$Constants.smali

Replace all values 0xea60 (60000ms /1min in hex) to however many ms you want the minimum interval to be example 30seconds 0x7530

Save and Smali back to classes.dex

java -Xmx512M -jar smali.jar extractfolder -o classes.dex

Open services.jar again in Winrar, delete classes.dex and drag the newly created classes.dex into services.jar.

Copy back to /system/framework/services.jar

Restart device.

Also on my Samsung device, having the word alarm OR alert(not tested) in the package name adds it to a whitelist. My alarms are fired exactly when I do this.
