所以我可以使用我的Gmail帐户在应用程序中使用AmazonSES成功发送不带附件的电子邮件，但是我很难找到一种解决方案来发送带附件的电子邮件。亚马逊提供了通过Java进行操作的说明，但是当我尝试执行操作时，我总是遇到错误。
我到了需要导入org.apache.httpcomponents的地步，但这没有用，因为我需要为其获取Android端口。现在我遇到了：
Caused by: java.lang.VerifyError: Verifier rejected class com.amazonaws.http.apache.request.impl.ApacheHttpRequestFactory: org.apache.http.client.methods.HttpRequestBase com.amazonaws.http.apache.request.impl.ApacheHttpRequestFactory.createApacheRequest(com.amazonaws.Request, java.lang.String, java.lang.String) failed to verify: org.apache.http.client.methods.HttpRequestBase com.amazonaws.http.apache.request.impl.ApacheHttpRequestFactory.createApacheRequest(com.amazonaws.Request, java.lang.String, java.lang.String): [0x43] register v0 has type Precise Reference: org.apache.http.client.methods.HttpPatch but expected Reference: org.apache.http.client.methods.HttpEntityEnclosingRequestBase (declaration of 'com.amazonaws.http.apache.request.impl.ApacheHttpRequestFactory' appears in /data/app/e.my.package-ki0yo2nHePW9QH2mDg31Kw==/split_lib_dependencies_apk.apk)
好的，然后我发现我需要一个用于AWS开发工具包的Android端口。然后，我在依赖项中添加了aws-android-sdk-ses-2.7.4.jar。现在，在我的代码中，我缺少这两个导入的依赖关系：
import com.amazonaws.regions.Regions;
import com.amazonaws.services.simpleemail.AmazonSimpleEmailServiceClientBuilder;
我不确定从这里去哪里。在添加Android AWS开发工具包之前，我调用了sendEmail（）方法之前，代码似乎运行良好。由于缺少两个输入，我现在无法编译。
这是我的类中的doInBackground（）方法，该方法扩展了AsyncTask：
@Override
protected String doInBackground(Object... params) {
try {
Log.i("SendMail", "About to instantiate GMail...");
AmazonSES androidEmail = new AmazonSES(params[0].toString(),
params[1].toString(), (FragCommunication) params[2]);
androidEmail.createEmailMessage();
publishProgress("Sending order....");
androidEmail.sendEmail();
publishProgress("Order Sent!");
Log.i("SendMail", "Order Sent.");
} catch (Exception e) {
Handler h = new Handler(Looper.getMainLooper());
h.post(new Runnable(){
public void run() {
Toast.makeText(sendMailActivityWeak.get(), "Failed to send order. Please try again later.",Toast.LENGTH_LONG).show();
}
});
}
return null;
}
