    Unless in rare cases you should not test for specific applications and use them explicitely but call intents that those application can process. E.g. you should only share content via an intent so any application that can handle this intent (like Facebook, Twitter, Tumblr, Pinterest, Mail, SMS, Dropbox...) can be used. – Hauke Ingmar Schmidt Aug 06 '12 at 13:13

Use this 

PackageManager pm = getPackageManager();
boolean s = false;
try{ 
     pm.getPackageInfo("app package",0); 
     s = true; 
} catch (Exception e ) { s= false; }

you can find app package on google play site (in page url)
