Due to a bug/issue in Dropbox SDK we must set the app name with an XML file.
Create a file named strings.xml and put it under Objects\res\values.
The file content should be:
Code:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">B4A Example</string>
</resources>
Change B4A Example to the correct app name.
Set the file to be read-only.
