在我的應用程序中運行tesseract OCR引擎期間發生錯誤

[英]Error occur during running the tesseract OCR engine in my application

我可以在調試應用程序時知道錯誤是什么嗎? 下面是我的編碼,並且tessdata保存在手機中。

public class testingtesting extends Activity {

private static final String data_path = "/mnt/sdcard/tessdata";

 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    //    setContentView(R.layout.image);

        ImageView a = (ImageView) findViewById (R.id.testingtesingt);
        Bitmap aa =  grayScale.bitmap_in_binarize;
  //      a.setImageBitmap(aa);

        TessBaseAPI baseApi = new TessBaseAPI();
        baseApi.setDebug(true);
        System.out.println("GGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGGG");
        //error

      //  File myDir = getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS);
        baseApi.init(data_path, "eng");
        //error
        baseApi.setImage(aa);
        System.out.println("adwdwawdada");
        String recognizedText = baseApi.getUTF8Text();
        baseApi.end();
        System.out.println("cimcaoioievfoaemmov");
        Intent intent = new Intent(testingtesting.this, result.class);
        intent.putExtra("title_input", recognizedText);
        startActivity(intent);


 }

請提供錯誤消息。

據我所知,您在使用System.out.println("GGGGGGGGGGGGGGGGGGGG");遇到了麻煩System.out.println("GGGGGGGGGGGGGGGGGGGG");

Android不使用標准Java控制台。 而是使用Logcat像這樣:

Log.d("testingtesting", "GGGGGGGGGGGGGGGGG");

如果您使用的是Eclipse,請在啟動時打開LogCat視圖以查看應用程序的輸出:

窗口→顯示視圖→其他→Android→LogCat
