安卓：分享图片的意图不是工作在Facebook？ [英] Android: Share Image intent not working with Facebook?

问题描述

您好我有以下的code共享图像：

Hi I have the following code to share an image:

// Share
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");

Uri uri = Uri.parse(getFilesDir() + File.separator + "myGoal.jpg");
        share.putExtra(Intent.EXTRA_STREAM, uri);

startActivity(Intent.createChooser(share, "Share Image"));

它的工作原理共享图像Dropbox的，但如果我选择了Facebook的选项，我得到Facebook的状态更新对话框，没有附加的图像，如果我尝试更新我与'测试'状态这是行不通的。没有错误。只是不工作。

It works to share the image to Dropbox but if I pick the Facebook option, I get Facebook's status update dialog with no image attached and if I try to update my status with 'Test' it doesn't work. No errors. Just not working.

我知道这是不是图像，因为它上传到我的Dropbox的正确，我可以拉起来的形象，看它。

I know it's not the image because it uploads to my Dropbox properly and I can pull up the image and look at it.

我必须将图像连接到不同的意图它与Facebook的工作？

Do I have to attach the image to the intent differently for it to work with Facebook?

任何想法？我调试一个物理设备上。

Any ideas? I'm debugging on a physical device.

推荐答案

所以我想通了这个问题。

So I figured out the problem.

我保存图片到内部存储器与getFilesDir（），它把图片放到我的应用程序沙箱中，并取得了无法访问其他应用程序。

I was saving the picture to internal storage with getFilesDir() which put the picture into my apps sandbox and made inaccessible to the other apps.

我代替我的code具有以下内容：

I replaced my code with the following:

String file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + 
                "/MyApp/";

File dir = new File(file_path);
dir.mkdirs();
File file = new File(dir, "myPic.png");
FileOutputStream fOut = new FileOutputStream(file);

screenshot.compress(Bitmap.CompressFormat.PNG, 100, fOut);

fOut.flush();
fOut.close();

// Share
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/png");

share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
share.putExtra(Intent.EXTRA_TEXT, "My Image");

startActivity(Intent.createChooser(share, "Share Image"));

工作完全正常了。

Works perfectly fine now.
