How to show an image through an intent being compatible with different apps(如何通过与不同应用程序兼容的意图显示图像)

问题描述

我正在尝试共享我之前保存在磁盘上的图像，发送 Intent.ACTION_SEND.问题是我找不到与不同应用程序、官方 Gmail 应用程序和 TweetDeck 兼容的方法.

I'm trying to share an image I have previously saved on disk, sending an Intent.ACTION_SEND. The problem is that I can't find a way to be compatible with different apps, official Gmail app and TweetDeck in my case.

我要分享的图片包含在一个文件中:

The image I want to share is contained in a File:

File agendaFile; 
// its path using getAbsolutePath() -> /data/data/com.mypackage/files/agenda.jpg

选项 A) 使用 Uri.fromFile

Uri agendaUri = Uri.fromFile(agendaFile); 
// the value -> file:///data/data/com.mypackage/files/agenda.jpg

结果

• Gmail，图片是否附在电子邮件中?否
• Tweetdeck，图片是否添加到推文消息中?是

Uri agendaUri = Uri.parse(agendaFile.toURI().toString()); 
// the value -> file:/data/data/com.mypackage/files/agenda.jpg

结果

• Gmail，图片是否附在电子邮件中?是
• Tweetdeck，图片是否添加到推文消息中?否

在这两种情况下，我都这样发送意图:

In both cases I send the intent like this:

final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("image/jpg");
intent.putExtra(android.content.Intent.EXTRA_STREAM, agendaUri);
startActivity(Intent.createChooser(intent, "title"));

那么，还有其他分享图片的选项吗?共享与大多数应用程序兼容的图像的最佳方式是什么?

So, is there any other options to share an image? How is it the best way to share an image being compatible with most apps as possible?

谢谢！

推荐答案

我终于解决了在MediaStore存储图片的问题.我所做的不是使用文件的 URI:

I finally solved the problem storing the image at the MediaStore. Instead of using the URI of the File what I do is:

String agendaFilename = agendaFile.getAbsolutePath();

final ContentValues values = new ContentValues(2);
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
values.put(MediaStore.Images.Media.DATA, agendaFilename);
final Uri contentUriFile = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

最后我使用 contentUriFile:

final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("image/jpg");
intent.putExtra(android.content.Intent.EXTRA_STREAM, contentUriFile);
startActivity(Intent.createChooser(intent, "title"));
