hi, I build this on Windows 7 and it working fine. but when a create a android app and copy the code:
1-File myDir = getExternalFilesDir(Environment.MEDIA_MOUNTED); 2-TessBaseAPI baseApi = new TessBaseAPI(); 3-baseApi.init(myDir, "eng"); // myDir + "/tessdata/eng.traineddata" 4-must be present 5-baseApi.setImage(myImage); 6-String recognizedText = baseApi.getUTF8Text(); // Log or otherwise I'm having problems on line 3, it ask for 2 string and myDir is not a string and what exactly do you mean on the first line? tnks!
