Android Studio-通过默认目录应用程序以编程方式打开epub + pdf文件

Question

如何打开默认文件管理器应用程序，该应用程序允许您通过Intent以编程方式选择文件，但扩展名为.epub或.pdf ？

Answer 1

The code shown is the declaration of the intent that you have to start for opening the default file manager app that let you choose a file but only with extension .epub or .pdf , I hope it will be useful.

Intent intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("application/epub+zip");
String[] mimetypes = {"application/epub+zip", "application/pdf"};
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
startActivityForResult(intent,PICKFILE_RESULT_CODE);

It is a mix of solutions I found that work so maybe it is redundant. Let me know what you think!
