Android: return to the Application Home Activity

Question

I am trying to use the next code to return back to the My Application Home Activity from the stack of my application:

protected void goHome(boolean offlineMode) {
    final Intent intent = new Intent(this, MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    startActivity(intent);
...
}

But in this case all other applications activities on the top will be closed too. Is it possible to close activities only of my application in this case?

This should do the work.

Intent i = new Intent(context, HomeActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK|Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
finish();

You can also implement this from your AndroidManifest.xml file, just adding

android:noHistory="true"

attribute in those <activity> you want (eg. HomeActivity)

see here is the sample code of manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.rdc.helloWorld"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".HelloWorldActivity"
            android:label="@string/app_name" 
            android:noHistory="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

so when you click back button on Home Activity screen, it will clear history of this screen only
