The code I used is same as the one in Sending Email in Android using JavaMail API without using the default/built-in app

This is my mainfest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="org.mailsend"
  android:versionCode="1"
  android:versionName="1.0"
  android:installLocation="preferExternal" >
 <uses-permission android:name="android.permission.INTERNET"></uses-permission>


<application android:icon="@drawable/icon" android:label="@string/app_name"       android:debuggable="true">
    <activity android:name=".MailSenderActivity.java"
              android:label="@string/app_name">
              <activity android:name=".GMailSender"></activity>
               <activity android:name=".MailSenderActivity"></activity>
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>

    </activity>


</application>

Can android do **that**? Could it send as you, or just decide to send random stuff from your memory card back to home base? Sounds vaguely scary. — Paul, Aug 23 '11 at 09:10
Please be more specific, post the logcat of your errors, post the code that's not working. Help people help you — Egor, Aug 23 '11 at 09:12
sorry since my rep is less on SO, I'm unable to paste images, so I've pasted the logcat as it is. — user838522, Aug 23 '11 at 09:51
@Paul: Of course Android can do that. Give it internet permissions and SD card permissions and it'll be able to open a connection to a webserver (any type including file or mail), and systematically upload your entire sd card. Though it'll need to be run at least once allowing it to start a service so that it wont be shut down by Android... — Kurru, Aug 23 '11 at 09:59

Check the package name in GMailSender.java file

  static {   
          Security.addProvider(new PACKED-NAME.JSSEProvider());   
         }

add code in JSSEProvider file

public final class JSSEProvider extends Provider {

    private static final long serialVersionUID = 1L;   ---> this code is add

You are missing the org.mailsend.MailSenderActivity class in your APK file, so it cannot be started. Either add this class to your APK file or modify the manifest to not include it (and do not try to start it).

that doesn't seem to be the problem and org.mailsend.MailSenderActivity is present in the class file. – user838522 Aug 23 '11 at 10:21
@user838522: It is the problem that is reported by your stack trace. – CommonsWare Aug 23 '11 at 10:22
I have one package called org.mailsend which holds 2 classes called GmailSender.java and MailSenderActivity.java and another package called com.provider which holds JSSEProvider.java; but why wouldn't it automatically add the packages into my apk file? – user838522 Aug 23 '11 at 10:29
@user838522: I have no means of answering that question, sorry. – CommonsWare Aug 23 '11 at 10:40
