java - Android app components - a word of advice needed -

-

I'm a whole newbie for Android development;

Actually, I'm going to write an application, which will allow the user to take a picture, which will be submitted for remote webservice (with a group of additional data).

So I'm guessing I'll need:

  1. Take a photo application (activity) which will collect all the additional data and put it in SQLite DB .
  2. A background service seeks DB in time intervals and sends data over the Internet, alternatively making web requests with the current GPS location (I am trying to keep in mind, sometimes Network will not be accessible)
  3. A receiver object that will run the service on boot, and optionally check that the service

has my concerns:

  1. I really need to monitor the service and care of anything that can kill it.
  2. Does the battery run for non-stop running at least 12 hours in Rvice, by doing some networking / GPS operations, let's say, 30 minute intervals. (G1 / Dream)
  3. What else should I be careful of?

Any ideas / suggestions will be appreciated.

a word of advice

.

Oh, wait. You're probably looking for some things related to Android, OK, move on.

A receiver object that will run the service on boot, and optionally check that the service needs to be restarted.

Yuck. Use the Alarm Manager and the behavior of your service / Windows is a scheduled task.

Do I really need to monitor the service and there is nothing bad that can kill it. >

If you use alarm manager and your service behaves like a cron job more.

Whether at least 12 hours with a non-stop running service, in some networking / GPS operations, we say, 30 minutes intervals. (G1 / Dream)

If you use alarm-manager and your service behaves like a cron job, then 30 minutes intervals Should be fine Just make sure that you turn off GPS radios when you complete it. Note that using GPS radios from cron job type work is a bit difficult, because it takes some time to make your first decision.

Should I be careful about what else?

And besides what I wrote above, you should be in the right shape. Note that the diver you are is not really "newbie" material.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
