Check if a package exists on Android Market

I am trying to find if a specific package already exists in Android Market.

I know I have no problem to actually open the Market application in the package page:

Intent intent开发者_如何学C = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=" + PACKAGE_NAME));
startActivity(intent);

But I want to know if it exists before I try this - so the user won't get the default "not found" market page.

One way to do it, of course, is to use the web Market URL with an HttpClient (https://market.android.com/details?id=) - this will return 404 if the package does not exist.

However, I'm looking for a way to do that with the Market application installed on the device.

You can perform a simple test on the Android market URL as

https://play.google.com/store/apps/details?id=com.mycompany.myapp

Pass your Application Package name with the letters indented in bold letters in above URL, if you get any result then it is concluded that the Application Package name is already been used, if you get "We're sorry, the requested URL was not found on this server." then you can use the app package name.

For details url and package name (https://play.google.com/store/apps/details?id=com.x.y.z)

Server returns

• HTTP 200: package exists.
• HTTP 404: package does exist

Both the accepted answer and other answer with links aren't working now (not sure if they did before). We're having an issue with one app (bundle already exists in Google Play, and those links return 404. My guess is if it's on internal testing and not publish that the bundle is already taken, but since app is not public, those links will return 404.
