I saw a contest that requested that people text or call in as many times as they can within a short period of time. As the contest rules didn't state anything about automation, I decided to write a script to do my bidding.
The final script was simple enough. By connecting my phone in debug mode to the computer, running android service, and using the following batch script, I was able to begin my bombardment in hopes of winning the contest. This simple code uses an infinite loop and within that calls instructions telling the phone to create a text message, then sends the commands to send the text message by simulating key presses, and then generates a random amount of time between 1 and 30 seconds before doing repeating the process (as an attempt to be at least somewhat reasonable and not fill up my carriers pipes).
adb shell am start -a android.intent.action.SENDTO -d sms:"+15015551234" --es sms_body "I want to win" --ez exit_on_sent true
adb shell input keyevent 22
adb shell input keyevent 66
SET /A die=30*%random%/32768+1
Now cross my fingers, that my carrier wont care too much... is unlimited texting really unlimited or is that within reasonable usage... btw, what is reasonable usage?
