How can I stop applications and services from running?
i've an Xperia X10 Mini. This Android devices is limited in hardware: a 600Mhz processor and 128 mb ram. So i'd like to install new apps, but i don't like to have a lot of apps running in background. For example, Facebook app, GDrive, Dropbox ... are great, but why 'damn' thei must run in background either if i don't want to use them at the moment ? This cause my device to run slowly, very slowly...
I know that facebook app for example, 'must' stay in background so it can inform me for a new 'friend post' .. but i don't need it! Also Gdrive, Dropbox, Gmail etc: they 'must' stay in background to inform me for something.. but i'm not interested !!! If i want to check mail... i click to gmail.. if i want to check my friend post... i click facebook !
What i want is a responsive smartphone for basic operation (call, sms etc.), and i'm sure a 600mhz processor with a basic 'android' installation and without background app can go fast as a double core Arm with 100 running app !!!!
So, at the moment i disinstall them, and my device back to run good, with no slowdowns.
I also have installed Advanced Task Killer, but it kills apps each hour, or 30minutes: it don't prevent an app to run in background.
Does exists an app that kill others app each time they start in background, immediately ?
