android email 邮件转发附件不能转发问题的解决

最近碰到android email 邮件转发附件不能转发问题，然后就仔细研究后，发现这个问题的解决很简单，所以对其进行了解决，并在自己的机子上进行了测试，下面我把代码给大家发出来。

在MessageCompose.java类中添加这两个方法：

private boolean findAttachmentWithMessageId(Context context,long messageId){
Uri uri = ContentUris.withAppendedId(Attachment.MESSAGE_ID_URI,messageId);
Cursor c = context.getContentResolver().query(uri,Attachment.CONTENT_PROJECTION,null,null,null);
boolean allAttachmentsDownload = true;
try{
int count = c.getCount();
for(int i = 0;i<count;++i){
c.moveToNext();
final Attachment attachment = new Attachment();
attachment.mFileName = c.getString(Attachment.CONTENT_FILENAME_COLUMN);
attachment.mContentUri = c.getString(Attachment.CONTENT_CONTENT_URI_COLUMN);
attachment.mSize = c.getLong(Attachment.CONTENT_SIZE_COLUMN);
attachment.mMimeType = c.getString(Attachment.CONTENT_MIME_TYPE_COLUMN);
if(attachment.mContentUri == null){
allAttachmentsDownload = false;
continue;
}

mHandler.post(new Runnable(){
public void run() {
addAttachment(attachment);
}
});
}
}finally {
c.close();
}
return allAttachmentsDownload;
}

private boolean loadAttachments(Message message,Context context){
return findAttachmentWithMessageId(context,message.mId);
}

在processSourceMessage()方法里面：else if(ACTION_FORWARD.equals(mAction))下
if(!loadAttachments(message,MessageCompose.this)){
mHandler.sendEmaptyMessage(MSG_SKIPPED_ATTACHMENTS);
}这段代码放开。

将MessagingController.java文件

loadAttachment方法里面的：
pruneCachedAttachments(accountId);注销掉

以上就是所修改的东西，改代码经过测试，大家可以放心的使用，谢谢！！！
