Check for storage permissions before uploading file

[kgehmlich]

Currently, if the app is not granted storage permissions, it crashes when trying to upload a file to the server. A check should be made to ensure that either
a) permissions are modified to grant storage access
or
b) no upload is attempted

Can't we set this for everyone in android manifest?

We can set it, but if the user then goes into his setting and changes it the app will crash. Apps still run even if certain permissions are not granted. So just adding the check in a If() condition will prevent a crash.
