应用已停止按钮单击在设备上执行OCR但在模拟器中正常工作

Question

我有这个代码按钮点击它在Android模拟器nexus 5中正常工作，但当我在Android手机中安装它并点击扫描按钮我得到错误不幸的是应用已经停止。

谁能帮助我？

Bundle extras = getIntent().getExtras();
String imgPath = extras.getString("picPath");
Bitmap bmp = decodeBitmapFile(imgPath, 1200, 1500);

btn1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            scanText();
        }
    });

public static int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;
    if (height > reqHeight || width > reqWidth) {
        final int halfHeight = height / 2;
        final int halfWidth = width / 2;
        while ((halfHeight / inSampleSize) > reqHeight
                && (halfWidth / inSampleSize) > reqWidth) {
            inSampleSize *= 2;
        }
    }
    return inSampleSize;
}
public static Bitmap decodeBitmapFile(String filePath,int reqWidth, int reqHeight) {
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(filePath, options);
    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
    options.inJustDecodeBounds = false;
    return BitmapFactory.decodeFile(filePath, options);}

执行OCR的代码

public void scanText(){
        try {
            ExifInterface exif = new ExifInterface(imgPath);
            int exifOrientation = exif.getAttributeInt(
                    ExifInterface.TAG_ORIENTATION,
                    ExifInterface.ORIENTATION_NORMAL);
            Log.v(TAG, "Orient: " + exifOrientation);
            int rotate = 0;
            switch (exifOrientation) {
                case ExifInterface.ORIENTATION_ROTATE_90:
                    rotate = 90;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_180:
                    rotate = 180;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_270:
                    rotate = 270;
                    break;
            }
            if (rotate != 0) {
                // Getting width & height of the given image.
                int w = bmp.getWidth();
                int h = bmp.getHeight();
                // Setting pre rotate
                Matrix mtx = new Matrix();
                mtx.preRotate(rotate);
                // Rotating Bitmap
                bmp = Bitmap.createBitmap(bmp, 0, 0, w, h, mtx, false);
            }
            bmp = bmp.copy(Bitmap.Config.ARGB_8888, true);
        } catch (IOException e) {
            Log.e(TAG, "Couldn't correct orientation: " + e.toString());
        }
        Log.v(TAG, "Before baseApi");
        TessBaseAPI baseApi = new TessBaseAPI();
        baseApi.setDebug(true);
        baseApi.init(DATA_PATH, lang);
        baseApi.setImage(bmp);
        String recognizedText = baseApi.getUTF8Text();
        baseApi.end();
        Log.v(TAG, "Scanned TEXT: " + recognizedText);
        if (lang.equalsIgnoreCase("eng")) {
            recognizedText = recognizedText.replaceAll("[^a-zA-Z0-9]+", "");
        }
        recognizedText = recognizedText.trim();
        if (recognizedText.length() != 0) {
            Intent x = new Intent(Main2Activity.this, Main3Activity.class);
            x.putExtra("txtScan", recognizedText);
            x.putExtra("pic", imgPath);
            startActivity(x);
            finish();
        } else {
            Toast.makeText(Main2Activity.this, "Error while extracting text..", Toast.LENGTH_LONG)
                    .show();
        }
}

这是LOGCAT中的错误
