从应用程序（android 4.3）在浏览器中打开本地文件

Question

I'm developing an app that must open a local file in browser. In android versions less than 4.3 it works perfectly but in versions equal or above 4.3 the app always crashes. I think the problem is in Intent.ACTION_VIEW, but I dont have sure.

The code that I wrote is showed below.

Intent browserIntent = new Intent(Intent.ACTION_VIEW);
browserIntent.setClassName("com.android.browser", "com.android.browser.BrowserActivity");
browserIntent.setType("text/html");
browserIntent.setData(uri);
startActivity(browserIntent);

So the question is: how to open a local file in browser from app in android versions equal or above 4.3.

Answer 1

Remove the setClassName() . You should not assume what browser apps are installed on the device. All it matters that you request that some user-chosen app handles the URI with the specified data type for you.

To be extra resilient, catch ActivityNotFoundException in case there's no activity to handle the intent (eg due to a restricted user profile).
