I wanna know if there is anyway to determine not through the packages, but through applications the version of an application which isnt the current application.
let's say right now i am in the scope of app A. and i wanna run an activity from app B. i wanna check before the version code of app B.
thanks,
ray.
This is a method I use to verify versions and if a particular package has been installed or not:
/** * Returns the version number we are currently in * @param appPackageName - full name of the package of an app, 'com.dcg.meneame' for example. */ public static int getAppVersionCode(Context context, String appPackageName) { if ( context!= null ) { try { return context.getPackageManager().getPackageInfo(appPackageName, 0).versionCode; } catch (NameNotFoundException e) { // App not installed! } } return -1; }
