Let's say you just created a new app and uploaded ( apk) it to the Android Market (Google Play) with all screenshots, details etc. Generally, it takes a couple of hours or more for it to be available on Google Play. But you want to know the URL of your app in Google Play. The URL of your app would be as follows: 


https://play.google.com/store/apps/details?id=com.your.package.name


All you have to do is change the package name in the above URL to the package name corresponding to your app. The package name is defined in the AndroidManifest.xml of your app e.g.


AndroidManifest.xml


<?xmlversion="1.0" encoding="utf-8"?>
<manifestxmlns:android="http://schemas.android.com/apk/res/android"
    package="codercrunch.com.courseapp"
    android:versionCode=”1″
    android:versionName=”1.0″]]?>
The URL would be:
https://play.google.com/store/apps/details?id=codercrunch.com.courseapp
