Question

我的应用程序几乎没有屏幕（活动）。从其中一个支持屏幕，我必须能够运行电子邮件，共享，其他活动。所以，我已经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[]{"elitedrumbeat@gmail.com"});
            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;

我建议它将运行默认的内置电子邮件应用程序，并将给用户选项以填写正文然后发送电子邮件。不幸的是，logcat给出了这个错误：

谷歌搜索我发现我需要添加以下行：

 emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

哪个不是优选的，但添加该行仍然没有帮助。那么，有什么想法吗？

Answer 1

问题已经解决。我不知道为什么我使用上下文来运行意图。

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

应该是

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

完成后，这有效。

错误：从活动外部调用活动
