Japanese text recognizer which scans documents and photos

Save several hundred dollars/euros, no hardware dictionary necessary. If you need a complete Japanese dictionary with many kinds of kanji and word search, Aedict is for you.

final Intent intent = new Intent("sk.baka.aedictocr.action.ACTION_OCR_KANJI");
startActivityForResult(intent, xx);

When the user OCRs a kanji, you will receive the kanji in the response:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == xx && resultCode == Activity.RESULT_OK) {
    String kanji = data.getStringExtra("kanji");
    // do something with the kanji.
  }
}
