＆QUOT;无活动来处理意图＆QUOT;同时，通过电子邮件发送数据 [英] "No Activity found to handle Intent" while emailing data

问题描述

我用这code试图邮件数据：

I am trying to mail data using this code:

email = (Button) findViewById(R.id.enail);
    email.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

            Intent emailIntent = new Intent(
                    android.content.Intent.ACTION_SEND);
            emailIntent.setAction(Intent.ACTION_SEND);
            emailIntent.setType("message/rfc822");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
                    new String[] { "" });
            emailIntent.putExtra(android.content.Intent.EXTRA_CC, "");
            emailIntent.putExtra(android.content.Intent.EXTRA_BCC, "");
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
                    "Playlist Details");
            emailIntent.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(Detail));
            emailIntent.setType("text/html");
            startActivity(emailIntent);

        }
    });

但它引发以下错误：

But it throws the following error:

请帮我。

推荐答案

我测试我的设备上，而code完美的作品。我testet这个code模拟器上，也和它坠毁。问题是，操作系统没有找到能够处理这个 ACTION_SEND 的任何活动。围绕这种code所有的时间用的try / catch ，因为你不能确定，如果存在，可以处理你的意图这样的活动。并尝试至少安装一个应用程序，可以处理 ACTION_SEND ，然后再试一次，看看它是否适合你。

I tested this on my device, and the code works perfectly. And I testet this code on an emulator, too, and it crashed. The problem is that the OS didn't find any activities which can handle this ACTION_SEND. Surround this kind of code all the time with a try/catch, since you can not be sure if there exists such an activity that can handle your intent. And try to install at least one app that can handle the ACTION_SEND, then try again, and see if it works for you.
