使用此代码打开相机

        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/" + StrFolderName + "/",filename + ".jpg"));
        intent.putExtra(MediaStore.EXTRA_OUTPUT,uri);
        startActivityForResult(intent,0);



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

        if (resultCode == RESULT_OK) {

            FileProcessing obj = new FileProcessing(FinalActivty.this);

            File f = new File(uri.getPath());
            Double capturedSize= Double.valueOf((float) f.length() / (1024));
            String Originalsize = String.format("%.5f",capturedSize);
            Double actualPhoto = Double.parseDouble(Originalsize);

        }

    }

解决方法

只需在清单应用程序标签属性中添加以下行即可。

android:requestLegacyExternalStorage="true"

但这是一个临时解决方案。来自 android r 的requestLegacyExternalStorage将被弃用。 有关更多详细信息，您可以参考此link

OR

只需替换您的文件路径，即可尝试以下代码

Uri uri = Uri.fromFile(new File(context.getExternalFilesDir(Environment.DIRECTORY_PICTURE) + "/" + StrFolderName + "/",filename + ".jpg"));
