使用Intent的android.content.ActivityNotFoundException

Question

我正在编写一个应用程序,我正在尝试发送包含一些数据的电子邮件,但每当我点击"提交"按钮发送电子邮件时,获取:不幸的是应用程序已停止

错误:

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.SEND typ=text/plain (has extras) }

码:

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
emailIntent.setType("text/plain");
String aEmailList[] = { "myaccount@gmail.com" };  
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, aEmailList); 
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);   
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(body.toString()));
startActivity(emailIntent);

logcat的:

几个月前我遇到了同样的问题,我找到了一个小解决方案,请尝试替换以下代码

Intent i = new Intent(Intent.ACTION_SEND);
    i.setType("plain/text");  
    i.putExtra(Intent.EXTRA_EMAIL, new String[]{"recepient@gmail.com"});
    i.putExtra(Intent.EXTRA_SUBJECT, subject);
    i.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(body.toString()));
    try {
     startActivity(i);
    } catch (android.content.ActivityNotFoundException ex) {
     Toast.makeText(Activity.this, "There are no email applications installed.", Toast.LENGTH_SHORT).show();
    }
}

如果您将获得没有安装电子邮件应用程序.消息,这意味着你的工作已经完成,我建议你在真实的设备上查看它,但我也不知道如何通过EMULATOR发送它
