Java 当我从mobile OnePlus 3 Android oreo的下载文件夹中选择file/Image/.doc时，Android应用程序崩溃

我正在使用Intent为文件选择器活动编写一些代码。代码在除onepluse 3之外的所有设备中都能正常工作。我检查异常我得到了NumberFormatException异常。我试图解决这个问题，但没有得到一个适当的解决办法。请给出解决这个问题的方法

    private void showFileChooser() {
       Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
       intent.addCategory(Intent.CATEGORY_OPENABLE);
       intent.setType("*/*");
       startActivityForResult(intent, PICK_FILE_REQUEST);
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == PICK_FILE_REQUEST && resultCode == RESULT_OK) {
            if (resultCode != RESULT_CANCELED) {
                if (data == null) {
                    //no data present
                    return;
                }


                Uri selectedFileUri = data.getData();

                Log.i("suraj", " FuelExpensesActivity Selected Uri Path:" + selectedFileUri);
              String  selectedFilePath = FilePath.getPath(this, selectedFileUri);
                Log.i("suraj", "FuelExpensesActivity Selected File Path:" + selectedFilePath);

                if (selectedFilePath != null && !selectedFilePath.equals("")) {

                    TextView tvFileName = new TextView(this);
                    tvFileName.setLayoutParams(new android.view.ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));

                    tvFileName.setPadding(5, 5, 5, 5);
                    tvFileName.setTextColor(Color.parseColor("#FFFFFF"));
                    tvFileName.setText(getFileName(selectedFileUri));
                    parent_layout_doc.addView(tvFileName);
                    parent_layout_doc.setPadding(5, 5, 5, 5);
                    imgUrl.add(selectedFilePath);

                } else {
                    Toast.makeText(this, "file not found.....", Toast.LENGTH_SHORT).show();
                }
            }

} }

public class FilePath {

                final String[] split = docId.split(":");
                final String type = split[0];

                if ("primary".equalsIgnoreCase(type)) {
                    return Environment.getExternalStorageDirectory() + "/"
                            + split[1];
                }

                // TODO handle non-primary volumes

                Uri contentUri = null;
                if ("image".equals(type)) {
                    contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

                final String selection = "_id=?";
                final String[] selectionArgs = new String[] { split[1] };

                return getDataColumn(context, contentUri, selection,
                        selectionArgs);

    }
    return  null;

}

public static String getDataColumn(Context context, Uri uri,
                                   String selection, String[] selectionArgs) {

    Cursor cursor = null;
    final String column = "_data";
    final String[] projection = { column };

    try {
        cursor = context.getContentResolver().query(uri, projection,
                selection, selectionArgs, null);
        if (cursor != null && cursor.moveToFirst()) {
            final int column_index = cursor.getColumnIndexOrThrow(column);
            return cursor.getString(column_index);
        }
    } finally {
        if (cursor != null)
            cursor.close();
    }
    return null;
}

public static boolean isExternalStorageDocument(Uri uri) {
    return "com.android.externalstorage.documents".equals(uri
            .getAuthority());
}


public static boolean isDownloadsDocument(Uri uri) {
    return "com.android.providers.downloads.documents".equals(uri
            .getAuthority());
}


public static boolean isMediaDocument(Uri uri) {
    return "com.android.providers.media.documents".equals(uri
            .getAuthority());
}

}

我也尝试下面的解决方案，但没有解决我的问题

                else if (isDownloadsDocument(uri)) {


                final String id = DocumentsContract.getDocumentId(uri);
                if (!TextUtils.isEmpty(id)) {
                    if (id.startsWith("raw:")) {
                        return id.replaceFirst("raw:", "");
                    }
                    try {
                        final Uri contentUri = ContentUris.withAppendedId(
                                Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
                        return getDataColumn(context, contentUri, null, null);
                    } catch (NumberFormatException e) {
                        e.printStackTrace();
                        Log.e("suraj", "Exception in FilePath "+ e.getMessage());
                        return null;
                    }
                }
            }

raw:/storage/simulated/0/Download/harley-davidson-vrod-tecnobike-img01~2.jpg不是一个数字。偶数/storage/emulated/0/Download/harley-davidson-vrod-tecnobike-img01~2.jpg不是一个数字，所以这是您的问题。看起来图像名没有完全取下，就像在harley-davidson-vrod-tecnobike-img01~2.jpg中一样，一些数字被转义并添加了特殊字符，请使用文件路径签入真实设备，然后进行比较，可用路径和检索路径是否相同..Markus Kauppinen我必须在哪里更改代码以及我必须在那里替换哪些代码？Pravin。。。当选择路径上方的文件时，选择FilePath=FilePath.getPaththis，选择FileUri；此行返回文件/图像的正确路径。在其他设备中，我得到了返回值，但在OnePlus 3中，它在selectedFilePath=FilePath.getPaththis，selectedFileUri中给了我异常；这一行看起来好像我们不能假设DocumentsContract.getDocumentId包含一个数字id。它返回一个字符串。它也可以是DonaldDucksCar313或任何有效字符串。所以，不要试图把它分解成一个长的。我不知道你的代码应该做什么，但是看起来你需要重新思考你的策略，以完成你想要完成的事情。
