Question

我可以在调试应用程序时知道错误是什么吗？下面是我的编码，tessdata保存在我的手机里面。

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);


 }

Answer 1

请提供错误消息。

从我收集到的内容来看，您遇到了System.out.println("GGGGGGGGGGGGGGGGGGGG");

的问题

Android不使用标准Java控制台。相反，像这样使用Logcat：

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

如果您正在使用Eclipse，请在启动时打开LogCat视图以查看应用的输出：

窗口→显示视图→其他→Android→LogCat
