Android Question Progress Bar

[khwarizmi]

I have a big data file in my e learning application as a zip file (about 1 Gigabyte) which I put in the File.DirAssets directory, when the application run in the first time It must copy the zip file to File.DirRootExternal and then unzip it to the File.DirInternal directory using Archiver library and then delete the zip file. user should not obstruct this process and a progress bar must appear. So How can I:
- Prevent user to obstruct the process.
- Show a progress bar for the total process.

File.Copy(File.DirAssets,"data.zip",File.DirRootExternal,"data.zip")
Arc.UnZip( File.DirRootExternal, "data.zip", File.DirInternal , "/data")
File.Delete(File.DirRootExternal,"data.zip")

Thanks

Why use File.DirRootExternal? It requires a special permission.

1. Use File.CopyAsync.
2. Use Archiver.UnzipAsync.

Thanks

I Use that File.DirRootExternal to hide the data file from the user.

I Use that File.DirRootExternal to hide the data file from the user.

The user can savely access the data on DirRootExternal. Just open a filebrowser and select the sdcard and you see the content.

So, is there any way to hide data ?

File.DirInternal

zip file (about 1 Gigabyte) which I put in the File.DirAssets directory

This is probably a stupid question, but: aren't install packages zipped anyway?

The assets files are zipped (the APK file is a zip file).

However if you want to maintain the folders structure or avoid having many files in the project then it makes sense to add them as a single zip file.
