I want to display compose email in Tab Activity. It is my code.

    TabHost.TabSpec spec;
    Intent intent;

    //View tabView= tabHost.getChildAt(0);
    //tabView.setPadding(0, 13, 0, 13);
    //tabView.setBackgroundColor(0xFFFFFFFF);
    intent=new Intent("com.android.phone.action.RECENT_CALLS").setClass(this,CallListActivity.class);
    spec=tabHost.newTabSpec("Call").setIndicator("Call").setContent(intent);
    tabHost.addTab(spec);

    intent=new Intent("android.intent.action.Compose_EMAIL");
    intent.setClassName("com.android.email", "com.android.email.activity.MessageCompose");
    spec=tabHost.newTabSpec("Message").setIndicator("Message").setContent(intent);
    tabHost.addTab(spec);    

    intent=new Intent().setClass(this, com.android.contacts.qs.logger.email.QsEmailLogger.class);

In your Application Manifest write the below lines,

android:sharedUserId="android.uid.shared"
android:sharedUserLabel="@string/sharedUserLabel"

The sharedUserId parameter is used to share the code,process,data between two apps. So thes code will apply in both the apps.

and also write these lines in your .mk file of both the apps...

LOCAL_CERTIFICATE := shared

on tab button click you can call a method

        tv_email.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                sendSimpleEmail(tv_email);
            }
        });        

this is a method which is used to open a compose email window ,call this method onClick

  public void sendSimpleEmail(View textView) {
    try {

  Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
        emailIntent.setType("plain/text");

        emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
                new String[] { email_add });
        startActivity(emailIntent);
    } catch (Exception e) {

        Toast.makeText(getApplicationContext(),
                "First Log in to your Email Account", Toast.LENGTH_LONG)
                .show();
    }
}
