我startActivityForResult从我的视图页面片段之一从相机获取图像，但在 android 版本 5 及更低版本中可以，但在 android 版本 6 中我有问题。

  @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

        Toast.makeText(getActivity(), "we are here Resultcode: "+requestCode, Toast.LENGTH_SHORT).show();
            if(resultCode!=-1 && data==null)
                return;
        Toast.makeText(getActivity(),"Getting readdy for image",Toast.LENGTH_LONG).show();
            switch(requestCode) {
                case PICK_IMAGE_ID:
                    Bitmap bitmap = ImagePicker.getImageFromResult(getActivity(), resultCode, data);
               /* Prescription_img=(ImageView)getActivity().findViewById(R.id.prescription);
                Prescription_img.setImageBitmap(bitmap);*/
                    Toast.makeText(getActivity(),"We are inside ",Toast.LENGTH_LONG).show();
                    File file= null;
                    try {
                        file = savebitmap(bitmap);
                        Log.d("file:",file.getName() + "  |is the file exist: "+file.getAbsolutePath());
                        f=file;
                        //control fragment menu to show step to get prescription from drugstore
                        Toast.makeText(getActivity(),"gott",Toast.LENGTH_LONG).show();

                        Log.i("getImage", "image gotten successfully");
                        Bundle args=new Bundle();
                        args.putString("image",f.getAbsolutePath());
                        _step2_fragmentconfirm_pic confirmPicFragment=new _step2_fragmentconfirm_pic();
                        confirmPicFragment.setArguments(args);
                        Toast.makeText(getActivity(),"getting image ready",Toast.LENGTH_LONG).show();
                        FragmentTransaction transaction=getFragmentManager().beginTransaction();
                        transaction.replace(R.id.root_menu_fragment,confirmPicFragment);
                        transaction.commit();


                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    break;
                default:
                    super.onActivityResult(requestCode, resultCode, data);
                    break;
            }
            Log.d("ImageGallary:",Integer.toString(requestCode));

        }

ImagePicker 类中的 getImageFromResult 方法在这里：

public static Bitmap getImageFromResult(Context context, int resultCode,
                                        Intent imageReturnedIntent) {
    Log.d(TAG, "getImageFromResult, resultCode: " + resultCode);
    Bitmap bm = null;
    File imageFile = getTempFile(context);
    if (resultCode == Activity.RESULT_OK) {
        Uri selectedImage;
        boolean isCamera = (imageReturnedIntent == null ||
                imageReturnedIntent.getData() == null  ||
                imageReturnedIntent.getData().toString().contains(imageFile.toString()));
        if (isCamera) {     /** CAMERA **/
            selectedImage = Uri.fromFile(imageFile);
        } else {            /** ALBUM **/
            selectedImage = imageReturnedIntent.getData();
        }
        Log.d(TAG, "selectedImage: " + selectedImage);

        bm = getImageResized(context, selectedImage);
        int rotation = getRotation(context, selectedImage, isCamera);
        bm = rotate(bm, rotation);
    }
    return bm;

}

我跟踪了应用程序，发现在尝试块中，当我想从 savebitmap 获取文件时，它让我捕捉到了这一行的部分：

file = savebitmap(bitmap);

这也是我完整的图像选择器类：

我试图通过这个命令 Log.i("Error",e.getMessage()); 在 catch 块中获取错误消息 并收到此消息：

在 android 6 中，您需要执行运行时权限

https://developer.android.com/training/permissions/requesting.html

例子

if (checkSelfPermission(Manifest.permission.CAMERA)
    != PackageManager.PERMISSION_GRANTED) {

    requestPermissions(new String[]{Manifest.permission.CAMERA , Manifest.permission.WRITE_EXTERNAL_STORAGE},
        MY_REQUEST_CODE);
}

并在结果活动中（确保您不打扰当前活动）

@Override
public void onRequestPermissionResult(int requestCode, String[] permissions,      int[] grantResults) {
    if (requestCode == MY_REQUEST__CODE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Now user should be able to use camera
        }
    else {
         // Your app will not have this permission. Turn off all functions 
         // that require this permission or it will force close like your 
         // original question
         }
    }
}

这段代码应该在去相机之前运行，如果他不给你不这样做，用户将授予你使用相机的权限并将图像保存到外部，并发送一个你需要权限的消息。
