Cannot determine whether Google play store is installed or not on Android device

Question

This was a simple matter of checking the installed packages on the device... before I\'ve upgraded my OS to 2.3.5, I could locate the Market/Play store, using this code:

Answer 1

In most case we want to find out whether Google Play Store is installed or not to launch it with some app page preloaded.

Why cant we do this:

final String appPackageName = getPackageName(); // get your app package name
try {
    Uri uri = Uri.parse("market://details?id=" + appPackageName);
    startActivity(new Intent(Intent.ACTION_VIEW, uri));
} catch (android.content.ActivityNotFoundException anfe) {
    // Google Play Store is not available.
}
