I've created an app where I assumed an ID opens a pdf file, but as it is now
pdfFile File = new File (Environment.getExternalStorageDirectory () "/ storage/sdcard0 /" + item.getID () + ". pdf ")
so I located it in myself on the phone, but how can I throw it into the app so I can share it with pdf files? Have tried to make a assets
under the res, but can not see where it is on your phone so / storage/sdcard0 /
can be changed to the location
Please give some more details - Do you want to check the file existence and take necessary action ? then you can proceed as follow-
File file = new File(Environment.getExternalStorageDirectory () "/ storage/sdcard0 /" + item.getID () + ". pdf ");
if(file.exists())
{
// do what you want
}
