I am creating a PDF file and saving it in local storage. When trying to open it, it is working perfect in all devices except in Android N. I am able to open PDF file in Android N using FileProvider, but it is displaying as blank.

This is my URI 

content://com.products.provider/external_storage_root/Android/data/com.products/in_17052017_170502_1_1001.pdf

This is my code

Uri path;

File pdfFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/"
                + "Android" + "/" + "data" + "/" + "com.products" + "/" + file);

if (Build.VERSION.SDK_INT >= 24) {
            path = FileProvider.getUriForFile(getActivity(), "com.products.provider", pdfFile);
        } else {
            path = Uri.fromFile(pdfFile);
        }

        // Setting the intent for pdf reader
        Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
        pdfIntent.setDataAndType(path, "application/pdf");
        pdfIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        pdfIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

        try {
            startActivity(pdfIntent);
        } catch (ActivityNotFoundException e) {
            Toast.makeText(getActivity(), "Can't read pdf file", Toast.LENGTH_SHORT).show();
        }

  1. Replace FileProvider class with MyFileProvider class:

path = MyFileProvider.getUriForFile(getActivity(), "com.products.provider", pdfFile);

where MyFileProvider should be a generic class which extends FileProvider:

public class MyFileProvider extends FileProvider {
}
  1. Modify AndroidManifest by setting your MyFileProvider class location to android:name attribute in your provider section: 
android:name=".utils.MyFileProvider"
