You released your app in English, but then you wanted to add French and Spanish versions. You added the English qualifier for the default values directory and then added 2 other value directories with French and Spanish qualifiers. Now, when you try to build the app, you encounter an error message: "Android resource linking failed."
What is the reason behind that? Here is a snapshot from the res directory tree:
res/
├── values-en/
│ ├── strings.xml # Strings in English
│ └── ...
├── values-fr/
│ ├── strings.xml # Strings in French
│ └── ...
├── values-es/
│ ├── strings.xml # Strings in Spanish
│ └── ...
└── ...
