如何启动浏览器打开本地文件 [英] How to launch browser to open local file

问题描述

我要发送意图浏览器打开本地文件。我希望使用默认浏览器打开此文件。

I'm trying to send intent to browser to open local file. I wish to use default browser to open this file.

if(file.exists()){
  Log.d(TAG, "file.exists");
  Intent intent = new Intent(Intent.ACTION_VIEW, Uri.fromFile(file));
  context.startActivity(intent);
}

但它引发我和exeption

But it throws me and exeption

08-10 13:27:58.993: ERROR/AndroidRuntime(28453): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///sdcard/release_notes.htm }

如果我用下面的意图浏览器中打开google.com预期

If I use following intent browser opens google.com as expected

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com"));

此外，当我写的文件的URL 。（文件：///sdcard/release_notes.htm）到浏览器的地址栏将打开它如预期

Also when I write the file url (file:///sdcard/release_notes.htm) to browser address bar it opens it as expected.

推荐答案

您需要添加可浏览的类别中的意图。

You need to add browsable category in the intent.

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.fromFile(file));
intent.addCategory(Intent.CATEGORY_BROWSABLE);
startActivity(intent);
