Go to the link http://apps.evozi.com/apk-downloader/.Enter the play store link or package name of the app you need.
Use evozi apk downloader extension for chrome from https://chrome.google.com/webstore/d...dlhdnbgbaiigba.You must add your google user id ,password and your phones device id in the options menu of the extension before you can download apps.Dont worry,the extension will store your user id and password in chromes local storage only and wont send anywhere.On the apps play store page you can see a download button on right extreme of address bar.Click it to download the app.More details on http://apps.evozi.com/apk-downloader/#guide
But this method is available for chrome users only.I,being a mozilla fan tried converting this extension for firefox using extensionlabs.But firefox show trouble storing the user id and password.
If you are a windows pc user,use the real apk leecher.Here also you must add your google user id ,password and your phones device id in the settings of this before you can download apps.Visit this thread http://forum.xda-developers.com/show....php?t=1563894.Why wait,try these out....
