Question: I am having trouble executing at command via php. When I start this job, it runs the 1st time and creates a queue job 1 minute from it finishes the Run Logic. The queued job runs at specified time but it will not create a new job queue 1 minute after it completes the Run Logic so it dies.

The pseudo logic is  

`//task_queue.php  

if(we_have_tasks){  

Run Logic  

shell_exec('/usr/local/bin/php -f task_queue.php | at now + 1 minutes');  

}`

What am I doing wrong? Any help is appreciated. I thought if I used the 'at' command I'll be able to schedule jobs without overlapping.

Thanks

Use JDK version 1.6 instead of 1.7 because 1.7 generates the fingerprint with SHA1 by default.
As much I know, the above which you got is the key, now u need to register it at this [link](http://code.google.com/android/maps-api-signup.html).
