推荐答案

我看到你要专门开Adobe公司，但你可能要考虑这样做打开一个总的意图，并允许用户更多的Andr​​oid样的方式选择如何打开。为了您的参考，你会做到这一点与下面的code：

I see that you want to open Adobe specifically, but you may want to consider doing it the more Android-like way of opening a general intent and allowing the user to choose how it opens. For your reference, you'd do that with the following code:

private void openFile(File f, String mimeType)
{
    Intent viewIntent = new Intent();
    viewIntent.setAction(Intent.ACTION_VIEW);
    viewIntent.setDataAndType(Uri.fromFile(file), mimeType);
    // using the packagemanager to query is faster than trying startActivity
    // and catching the activity not found exception, which causes a stack unwind.
    List<ResolveInfo> resolved = getPackageManager().queryIntentActivities(viewIntent, 0);
    if(resolved != null && resolved.size() > 0)
    {
        startActivity(viewIntent);
    }
    else
    {
        // notify the user they can't open it.
    }
}

如果你真的需要同时使用精舍读​​者特别，和特定的版本，你需要查询它使用<一个href="http://developer.android.com/reference/android/content/pm/PackageManager.html#getPackageInfo%28java.lang.String,%20int%29"><$c$c>PackageManager.getPackageInfo(String, INT）

If you really need to use both Abode Reader specifically, and a specific version, you would need to query for it using PackageManager.getPackageInfo(String, int)
