android - ExifInterface 获取了不受支持的图像

Question

我用过ExifInterface在 Android 应用程序中用于获取图像的相机方向。我的代码完美适用于 Build.VERSION.SDK_INT < 24 。但是当构建版本大于或等于 24 时，它会在 android studio logcat 中发出警告并且无法正常工作。

这是我的 onActivityResult 方法的代码块:

if(requestCode == REQUEST_CAPTURE_IMG && resultCode == RESULT_OK) {
            Log.d(TAG, "Inside camera operation");
            int reqWidth = 480, reqHeight = 800;
            try {
                InputStream inStream = null;
                try {
                    inStream = getContentResolver().openInputStream(imageUri);

                    //Decode image size
                    BitmapFactory.Options options = new BitmapFactory.Options();
                    options.inJustDecodeBounds = true;

                    BitmapFactory.decodeStream(inStream, null, options);
                    inStream.close();

                    options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

                    options.inJustDecodeBounds = false;
                    inStream = getContentResolver().openInputStream(imageUri);

                    CommonStaticClass.mImage = BitmapFactory.decodeStream(inStream, null, options);

                    ExifInterface exif = null;

                    try {
                        //File pictureFile = new File(imgDecodableString);
                        if (Build.VERSION.SDK_INT >= 24) {
                            exif = new ExifInterface(inStream);
                            Log.d("exif", "sdk 24");
                        }
                        else {
                            exif = new ExifInterface(imageUri.getPath());
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                    int orientation = ExifInterface.ORIENTATION_NORMAL;

                    if (exif != null)
                        orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

                    switch (orientation) {
                        case ExifInterface.ORIENTATION_ROTATE_90:
                            CommonStaticClass.mImage = rotateBitmap(CommonStaticClass.mImage, 90);
                            break;
                        case ExifInterface.ORIENTATION_ROTATE_180:
                            CommonStaticClass.mImage = rotateBitmap(CommonStaticClass.mImage, 180);
                            break;

                        case ExifInterface.ORIENTATION_ROTATE_270:
                            CommonStaticClass.mImage = rotateBitmap(CommonStaticClass.mImage, 270);
                            break;
                    }

                    inStream.close();
                } catch (IOException e) {
                    //Toast.makeText(this, "IO exception", Toast.LENGTH_SHORT).show();
                    Toast.makeText(this, SelectSuitActivity.this.getString(R.string.wrong_msg), Toast.LENGTH_SHORT).show();
                }
                //CommonStaticClass.mImage = MediaStore.Images.Media.getBitmap(getContentResolver(), imageUri);
                startActivity(intent);
            } catch (Exception e) {
                Toast.makeText(this, SelectSuitActivity.this.getString(R.string.wrong_msg), Toast.LENGTH_SHORT).show();
            }
        }

这是我从相机中选取图像时的 logcat 结果:

    10-19 12:39:04.399 2912-2912/com.example.myapp I/ExifInterface_JNI: Corrupted image.
    10-19 12:39:04.414 2912-2912/com.example.myapp W/ExifInterface: Invalid image: ExifInterface got an unsupported image format file(ExifInterface supports JPEG and some RAW image formats only) or a corrupted JPEG file to ExifInterface.

如果有人能找出这里出了什么问题，那将会很有帮助。谢谢。

您可以在 BitmapFactory 使用 inStream 后使用它。这是不可能的。再次打开流。
