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

GooglePlayServices has a utility class with a method to handle this:

isGooglePlayServicesAvailable(Context).

It provides appropriate error dialogs for the status of play services on the device.

API Reference:

GoogleApiAvailability.isGooglePlayServicesAvailable(android.content.Context)

Be aware that this almost 5 years old code is not optimal and Google does not like when you check all installed packages without no good reason. Please check also the other answers.

The package name has changed, it is now com.android.vending

Try:

private static final String GooglePlayStorePackageNameOld = "com.google.market";
private static final String GooglePlayStorePackageNameNew = "com.android.vending";

void someMethod() {
    PackageManager packageManager = getApplication().getPackageManager();
    List<PackageInfo> packages = packageManager.getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES);
    for (PackageInfo packageInfo : packages) {
        if (packageInfo.packageName.equals(GooglePlayStorePackageNameOld) ||
            packageInfo.packageName.equals(GooglePlayStorePackageNameNew)) {
            googlePlayStoreInstalled = true;
            break;
        }
    }
}
