I have implemented the codes it is very useful. Actually the comments for this line is missing so it is little bit confusing.. Although i have set the permissions to write external and internal storage in the Android manifest. Im using the android 6. How to browse for the pdf and word files, which type should be given to browse and upload these files?
I wanted to store it in the internal memory of the app. How do i store it here and retrieve the PDF to display it. Any idea? Here in this example we have DB Operation or some other Task in a private class included in our Activity.
What if we want to write a class that can be used in common for all the DB Operations in out Android App? This image is for thumbnail purpose. Ravi Tamada. Notify of. Oldest Newest Most Voted.
