Adroid：如何在app中访问到在market当中的其它apps

Even better to use "market://details" instead of "market://search":

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.android.example"));
startActivity(intent);

Then it opens directly the details page of the app. With search it shows a single search result and the user has to do an additional click to get to the detail page.
