错误:活动外的呼叫活动

Question

i确实有一个屏幕（活动）的应用程序。从其中一个（即支持屏幕）中，我必须能够运行电子邮件，共享其他活动。因此，我以这种方式添加了发送电子邮件选项：

 case R.id.firstColumn:
            /* Create the Intent */
            final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
            /* Fill it with Data */
            emailIntent.setType("plain/text");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"[e-mail]"});
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Feedback from customers");

            /* Send it off to the Activity-Chooser */
            context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
            break;

我提出，它将运行在电子邮件应用程序中内置的默认值，并将提供给用户选项以填写身体，然后发送电子邮件。不幸的是，LogCat给出了此错误：

谷歌搜索我发现我需要添加以下行：

 emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

这不是可取的，但是添加该行仍然没有帮助。那么，有什么想法吗？

问题已经解决。我不知道为什么我将上下文用于跑步意图。

context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));

应该是

 startActivity(Intent.createChooser(emailIntent, "Send mail..."));

完成，这有效。
