Readme

A mobile translation app that I wrote to learn mobile programming. This app uses the Deepl API service to perform translation and allows translating text from the clipboard, a text file, from an image in the gallery or from a picture taken on the spot.
The image parsing is done by using the Opencv image editing library to optimize the image for OCR and the Java implementation of Tesseract to extract the text.
To improve the character detection accuracy it is possible to download language-specific training data used by the OCR library. The files can be downloaded or removed in the dedicated config tab.
Since the translation is performed by invoking the Deepl APIs, the user must provide a valid API Key in the Config tab. The key is then stored in the application's Sqlite database so it can be specified only once.
The app will allow to verify the validity of the key and keep track of the translated characters quota.
