Android的图像裁剪乌里异常 [英] Android Image Crop Uri Exception

问题描述

先上去，我使用Xamarin，但问题是在本地Java项目相同的。
我更新SDK 5.1和遇到的code一个奇怪的错误，以前工作的罚款。

first up, I am using Xamarin, but the problem is the same on a native Java project. I was updating the SDK to 5.1 and encountered a strange error on code that worked fine before.

  imageStream = "file://" + imageStream;

            Mvx.Trace("path: " + imageStream);

            img = imageStream;

            try {
                Intent cropIntent = new Intent("com.android.camera.action.CROP");
                // indicate image type and Uri
                var fileUri = Android.Net.Uri.Parse(imageStream);
                cropIntent.SetDataAndType(fileUri, "image/*");
                // set crop properties
                cropIntent.PutExtra("crop", "true");

                // indicate aspect of desired crop
                cropIntent.PutExtra("aspectX", 5);
                cropIntent.PutExtra("aspectY", 4);
                // indicate output X and Y
                cropIntent.PutExtra("outputX", 1000);
                cropIntent.PutExtra("outputY", 800);
                // retrieve data on return
                cropIntent.PutExtra("return-data", true);

                // start the activity - we handle returning in onActivityResult
                StartActivityForResult(cropIntent, PIC_CROP);
            }

IST的ImageStream该文件的路径。图像割草机自身加载了罚款和作品。然而，当我打救我得到的logcat以下异常：

imageStream ist the file's path. The image cropper itself load up fine and works. However when I hit save I get the following exception in logcat:

E/AndroidRuntime( 5333): FATAL EXCEPTION: BackgroundTask #1
E/AndroidRuntime( 5333): Process: com.google.android.apps.photos, PID: 5333
E/AndroidRuntime( 5333): java.lang.IllegalArgumentException: mediaStoreUri must be a MediaStore Uri

我没有找到在MediaStore或MediaStore.Image命名空间类似的方法向Android.Net.Uri.Parse。这是否意味着我必须首先将图像保存到MediaStore，然后调用的意图之前找回？还是有一个明显的解决方案，我只是错过了吗？

I didn't find a similar method to the Android.Net.Uri.Parse in the MediaStore or MediaStore.Image namespaces. Does this mean I would first have to save the image to MediaStore and then retrieve it before calling the intent? Or is there an obvious solution which I simply missed?

干杯

推荐答案

好吧，看来我真的错过了一些东西在这里，延长了code的URI检索放像进入媒体商店第一。

Ok it seems I really missed something here, extended the code for the uri retrieval to put the image into the media store first.

var file = new Java.IO.File(imageStream);
var bmp = BitmapFactory.DecodeFile(file.AbsolutePath);
img = MediaStore.Images.Media.InsertImage(ContentResolver, bmp, "" ,"");
var fileUri = Android.Net.Uri.Parse(img);

我喜欢这种感觉，也许矫枉过正，如果可以随意发表评论。但至少它解决了问题。

I feel like this maybe overkill, if so feel free to comment. But at least it solves the issue.
