Question

我在通过mms intent附加视频文件（它总是小于100KB）时遇到了问题。虽然这在karbonn A21（ICS 4.0.4）上运行良好，但在HTC one V（ICS 4.0.3）和lg-p920（2.2.2）上附着失败。我得到一个像＃34;无法将视频附加到消息＆＃34;

的祝酒词

这是我的代码

Uri uri = Uri.fromFile(videoFile);

Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("video/3gp");
sendIntent.setClassName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity");
sendIntent.putExtra("sms_body", "some text here");
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(sendIntent);

关于我能做什么的任何提示/线索/指示都会有所帮助。

这个问题导致因为在视频/图像中需要添加到厨房：

中的代码

http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android-apps/2.3.3_r1/com/android/mms/ui/ComposeMessageActivity.java

关注addAttachment部分，我看到了

  String path = c.getString(c.getColumnIndexOrThrow(Images.Media.DATA));
    mSrc = path.substring(path.lastIndexOf('/') + 1);
    mContentType = c.getString(c.getColumnIndexOrThrow(
    mages.Media.MIME_TYPE));
    if (TextUtils.isEmpty(mContentType)) {
    throw new MmsException("Type of media is unknown.");
    })

我们看到这个消息不清楚并引起误解。

要解决此问题，您需要将文件添加到图库，将URI从contentResolver.insert传递给Intent并使用密钥Intent.EXTRA_STREAM

我使用MMS时的另一种体验，默认的Activity类用于在设备和制造商之间发送MMS更改，因此setClass com.android.mms.ui.ComposeMessageActivity并不总是正确的，它可能导致ActivityNotFoundException。当它发生时，你必须调用setPackge（“com.android.mms”）并删除setClass调用。希望有所帮助

到目前为止，我的方法是让用户通过gmail，youtube等分享视频以及通过mms分享的选项

ContentValues content = new ContentValues(4);
content.put(Video.VideoColumns.TITLE, "Cool Video");
content.put(Video.VideoColumns.DATE_ADDED,
            System.currentTimeMillis() / 1000);
content.put(Video.Media.MIME_TYPE, "video/3gp");
content.put(MediaStore.Video.Media.DATA, videoFile.getAbsolutePath());

ContentResolver resolver = parentActivity.get().getContentResolver();

//I use two URI's. One for the intent with mms(MMSUri) and the   
//other(ShareURi) is for sharing video with other social apps like
//gmail, youtube, facebook etc. 
Uri ShareUri = resolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,content);
Uri MMSUri = Uri.fromFile(videoFile);

List<ResolveInfo> resInfo = getPackageManager().queryIntentActivities(sendIntent, 0);
if(!resInfo.isEmpty())
{
    for (ResolveInfo resolveInfo : resInfo) 
    {
        String packageName = resolveInfo.activityInfo.packageName;
        Intent targetIntent = new Intent(Intent.ACTION_SEND);
        targetIntent.setType("video/3gp");
        targetIntent.setPackage(packageName);

        if(packageName.contains("mms"))
        {
             targetIntent.putExtra("sms_body", "Some text here");
             targetIntent.putExtra(Intent.EXTRA_STREAM, MMSUri);
        }
        else
        {
            targetIntent.putExtra(Intent.EXTRA_SUBJECT, "I can has videos?");
            targetIntent.putExtra(Intent.EXTRA_TITLE, "Some title here");
            targetIntent.putExtra(Intent.EXTRA_TEXT,"You have gots to watch this");
            targetIntent.putExtra(Intent.EXTRA_STREAM, ShareUri);
        }
        targetedIntents.add(targetIntent);
    }           

    Intent chooserIntent = Intent.createChooser(targetedIntents.remove(0), "Select app to share");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedIntents.toArray(new Parcelable[]{}));

    startActivity(chooserIntent);
    return;
}

Toast.makeToast(this, "No intents found for this action", Toast.LENGTH_SHORT, Gravity.CENTER).show();

我尝试为Intent.createChooser填充我自己的目标意图，只知道这些可用于附加/上传我的视频

编辑：我不会接受我自己的答案作为正确答案。我最乐观的是那里有一个更好的那个

将视频附加到mms意图在特定设备上失败
