    try {
      startActivity(intent);
    } catch (ActivityNotFoundException ex) {
        intent.setPackage(null);
      startActivity(intent);

Answer 1

试试这个：

Uri uri2 = Uri.fromFile(new File(Environment.getExternalStorageDirectory().getAbsolutePath()
    + File.separator + "new folder"+ "/index.html"));
Intent intent = new Intent(Intent.ACTION_VIEW, uri2);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setClassName("com.android.chrome", "com.google.android.apps.chrome.Main");

try {
    startActivity(intent);
} catch (ActivityNotFoundException ex) {
    try {
        intent.setPackage(null);
        startActivity(intent);
    } catch (Exception e) {}
}
