Android 操作\u图像\u捕获导致无法传递结果信息

在SAMSUNG TAB 3中拍摄图像时，在ActivityResult（）上给出错误

（用于Nexus工作）：

是否有任何通用代码可用于所有设备

    public void openImageIntent(View view) {

        // Determine Uri of camera image to save.
        final File root = new File(KOOPSv3.getFolderPath(context, context.getResources().getString(R.string.folder_expense)));

        final String fname = staff_id + new Date().getTime() + Math.abs(new Random().nextInt()) + ".jpg";

        path = root.getPath() + File.separator + fname;

        Log.d("koopsv3", "PATH : " + path);

        final File sdImageMainDirectory = new File(root, fname);
        outputFileUri = Uri.fromFile(sdImageMainDirectory);

        // Camera.
        final List<Intent> cameraIntents = new ArrayList<Intent>();
        final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        final PackageManager packageManager = getPackageManager();
        final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);

        for(ResolveInfo res : listCam) {
            final String packageName = res.activityInfo.packageName;
            final Intent intent = new Intent(captureIntent);
            intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
            intent.setPackage(packageName);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
            cameraIntents.add(intent);
        }

        // File System.
        final Intent galleryIntent = new Intent();
        galleryIntent.setType("image/*");
        galleryIntent.setAction(Intent.ACTION_PICK);

        // Chooser of file system options.
        final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Image");

        // Add the camera options.
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));

        startActivityForResult(chooserIntent, 1010);
    }

在Tablet 3的
onActivityResult（）
中，我得到了
NULL
，我如何解决这个问题

我怎样才能解决这个问题

如果
Intent
为
null
，请检查文件是否位于您请求的位置。如果你这样做了，就用它。如果没有，请告诉用户他们选择的应用程序已损坏，然后重试

传递给您的
onActivityResult（）
方法的
Intent
是您从另一个应用程序接收的输入。您需要使用防御性编程方法，因为输入可能并不总是您所期望的。理论上，
ACTION\u IMAGE\u CAPTURE
将返回一致的结果。实际上，在数千个摄像头应用程序中有数千种不同的实现，并且不是每个开发人员都能充分测试他们的应用程序
ACTION\u IMAGE\u捕获
