I was working on and app that would make a phone call when it’s started. When the call is done, instead of showing the Dialer, Call log, Contacts .. screen, i get the default black window (main.xml) created by the android adt.

After going through the Dev Guide, i found you can use the android:noHistory attribute to remove the activity from the activity stack. Here’s the AndroidManifest.xml of my project:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.ipthing.TestApp"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TestApp"
                  android:label="@string/app_name"
                  android:stateNotNeeded="true"
                  android:noHistory="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="3" />
<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>
</manifest>
