try this code :
protected boolean isAppInstalled(String packageName) {
Intent mIntent = getPackageManager().getLaunchIntentForPackage(packageName);
if (mIntent != null) {
return true;
}
else {
return false;
}
}
to get the package name of the app easily : just search your app in the google play website , and then you will take the id parameter ( it is the package name of the app) . Example :
you will search on Youtube app on google play , and you will find it in this url :
the package name is the id param, so it is : com.google.android.youtube
And then when you want to test , you will just have :
String packageName = "com.google.android.youtube";
boolean isYoutubeInstalled = isAppInstalled(packageName);
PLUS : if you want to get the list of all installed apps in you device , you can find your answer in this tutorial

you can't get it from the apk file, you will get it from the packageManager after you install it .

No doubt your post is really helpful , but i am getting a exception "java.lang.RuntimeException: Adding window failed" and " E/AndroidRuntime(7554): Caused by: android.os.TransactionTooLargeException 05-14 11:37:25.305: E/AndroidRuntime(7554): at android.os.BinderProxy.transact(Native Method) 05-14 11:37:25.305: E/AndroidRuntime(7554): at android.view.IWindowSession$Stub$Proxy.add(IWindowSession.java:516) 05-14 11:37:25.305: E/AndroidRuntime(7554): at android.view.ViewRootImpl.setView(ViewRootImpl.java:494) "

final Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List pkgAppsList = context.getPackageManager().queryIntentActivities( mainIntent, 0);
You'll get the list of all installed applications on Android.

Use this to check if an application is installed
PackageManager pm = context.getPackageManager();
List<ApplicationInfo> list = pm.getInstalledApplications(0);
for (int i = 0; i < list.size(); i++) {
if(list.get(i).packageName.equals("com.my package")){
//do what you want
}
}

In Youtube Player API, you can access YoutubeIntents class and use isYoutubeInstalled to verify if device has the Android app or not.
