Avoid the current activity finish when shart a notification

I want to start a notification in current Activity which is ChatActivity. When I press the notification, I want to enter the ChatOneActivity.

However I don't want the current ChatActivity finished when I'm in the ChatOneActivity. Because I'm receiving the data and when I press the back button, I want to stay in the ChatActivity.

The point is I do not want the ChatActivity to finish, no matter which Activity I am currently in.

So what should I do?

Here is the code

private void showNotification(String id, String message) {
    NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext())
    .setSmallIcon(android.R.drawable.sym_action_email)
    .setContentTitle("You have a new message")
    .setContentText(message);
    Intent intent = new Intent(ChatActivity.this,ChatOneActivity.class);
    intent.putExtra("toId", id);
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(ChatActivity.this);
    stackBuilder.addParentStack(ChatOneActivity.class);
    stackBuilder.addNextIntent(intent);
    PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_CANCEL_CURRENT);
    builder.setContentIntent(pendingIntent);
    NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    mNotificationManager.notify(1, builder.build());
}

The problem is:

Now I enter the ChatOneActivityand when I press the back button, I return to the desktop. Means that the ChatActivity has already finished which I don't want.

Here is the mainfest

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

<uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="16" />

<uses-permission android:name="android.permission.INTERNET" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.webmobilegroupchat.MainActivity"
        android:label="@string/app_name" >
    </activity>
    <activity
        android:name="com.example.webmobilegroupchat.ChatActivity"
        android:label="@string/title_activity_chat" >
    </activity>
    <activity
        android:name="com.example.webmobilegroupchat.ChatOneActivity"
        android:label="@string/title_activity_chat_one" >
    </activity>
    <activity
        android:name="com.example.webmobilegroupchat.SplashActivity"
        android:label="@string/title_activity_splash" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

your code is looking fine for creating notification but you have to define parent activity in Manifest also to navigate back, stackBuilder.addParentStack assumes that you define it in Manifest as well for API 16+:

<activity android:name=".ChatOneActivity"
    android:parentActivityName=".ChatActivity"
    ... />

for < API 16:

<activity android:name=".ChatOneActivity">
<meta-data
    android:name="android.support.PARENT_ACTIVITY"
    android:value=".ChatActivity" />

Try this on ChatOneActivity activity . 

  @Override
  public void onBackPressed() {
    super.onBackPressed();
    Intent intent = new Intent(getApplicationContext(),ChatActivity.Class);
    startActivity(intent);
}
