在Android设备上访问SD卡上的PDF文件

Question

I am currently developing an app for android which would allow a User to Upload a PDF file from their SD card to the servers. I've looking at a tutorial to upload an Image to a server to understand the technical aspects of uploading a file.

Intent pickImageIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickImageIntent, REQUEST_PICK_IMAGE);

I was looking at this and wondering how I would edit this code so the user could access the SD card and select a PDF file rather that the media store gallery?

Answer 1

You'll have to create an Intent like:

Intent intent = new Intent();
intent.setType("*/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
// Always show the chooser (if there are multiple options available)
startActivityForResult(Intent.createChooser(intent, "Select PDF"), REQUEST_PICK_PDF);

This will allow the user to select any type of file so you'll have to check the extension in onActivityResult(...) and proceed accordingly.
