I'm trying to download file from server here when i download small .png files they get downloaded successfully without any problem but when it comes to downloading large files my app is crashing with illegal argument exception stating that set percentage is not between 0 and 100.
Here is the error log which i'm getting:
java.lang.IllegalArgumentException: setPercentage not between 0 and 100

Here is my java class Note: To make it easy to understand i'm giving only the necessary portion as this is a adapter class which having a seperate download file class to support file download.
