Question

What is the easiest way to see if a user has a specific app in the Android Market, in my case Flash Player. If they don’t have it I want to be able to take them to the Market to download it before continuing on with the app. Thanks.

Here is a similar question about checking for Flash Player.

The relevant code (taken from Lior’s answer) is this:

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.adobe.flashplayer", "com.adobe.flashplayer.FlashExpandableFileChooser"));
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(intent, 0);
if (activities != null && activities.size() > 0)
{
    Toast.makeText(this, "Flash is installed!", Toast.LENGTH_LONG).show();
}
else
{
    Intent flashIntent = new Intent(Intent.ACTION_VIEW,Uri.parse("https://market.android.com/details?id=com.adobe.flashplayer"));
    startActivity(flashIntent);
}
