Java intent- setaction FOR FILES

To use an Intent to open a file on Android, you can use the ACTION_VIEW action and set the data and type to the Uri of the file and the MIME type of the file, respectively. For example:

File file = new File(filePath);
Intent i = new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(file), "application/pdf");
startActivity(i);

In this example, filePath is the path to the file on the device, and the MIME type is set to "application/pdf" for a PDF file. This Intent will open the file in an app that can handle PDF files, such as the default PDF viewer app.

You can use a similar approach to open other types of files by setting the appropriate MIME type. For example, to open an image file, you can use the MIME type "image/*".

It's important to note that this code will only work if the device has an app installed that can handle the specified file type.
