How to open a PDF via Intent from SD card

Try this code, display pdf file From /sdcard

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");Intent intent = new Intent(Intent.ACTION_VIEW);intent.setDataAndType(Uri.fromFile(file), "application/pdf");intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);startActivity(intent);

For Android Nougat and above some more work have to be done otherwise the app won't be able to open the .pdf file. We have to set a temporary permission to URI using the FileProvider:

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {     File file=new File(mFilePath);     Uri uri = FileProvider.getUriForFile(this, getPackageName() + ".provider", file);     intent = new Intent(Intent.ACTION_VIEW);     intent.setData(uri);     intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);     startActivity(intent); } else {     intent = new Intent(Intent.ACTION_VIEW);     intent.setDataAndType(Uri.parse(mFilePath), "application/pdf");     intent = Intent.createChooser(intent, "Open File");     intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);     startActivity(intent); }
