Question

当我在模拟器上运行我的应用程序时，它会发送电子邮件（正如我所料）但当我尝试在设备上运行我的应用时，它说“发送电子邮件时出现问题”。 ..... 我已经添加了3个jar文件i-e mail.jar，附加的，激活的我已经在清单中添加了互联网权限......

代码在这里

我找到了解决方案

实际上存在api combatibilty问题

首先添加onCreate方法

  if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
      }

然后更改显示文件

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="15" />

现在它在我的模拟器+移动设备上工作正常

我的JavaMail应用程序在模拟器上工作正常，但它不能在我的Android移动设备上运行
