Fatal Exception applicationId is null Parse

This is my second question in SO, I have a problem about Fatal Main error. Before I ask it, I found some other problem in SO, but what I found is about Facebook app
This is my error
java.lang.RuntimeException: applicationId is null. You must call Parse.initialize(context, applicationId, clientKey) before using the Parse library.
But, I have a class that declared it
package com.example.michael.eksperimen6chatting;
import android.app.Application;
import com.parse.Parse;
/**
* Created by Michael on 03/12/2015.
*/
public class ChattApp extends Application
{
#Override
public void onCreate()
{
super.onCreate();
Parse.initialize(this, "urkcFwvUmgSYvuOFTInJmkA3iWv0ArV3XT128TNb", "WvBC0cnGXHkVhTBbkFwLyxGDRgqR6qC8ft7DIleT");
}
}
and this is my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Did I miss something here, can anyone help me? Gratia

Specifying ChattApp Application class name in your AndroidManifest.xml's <application> tag.
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"

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

manifest file
For eclipse add this :
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
If you are using Android Studio(latest version) with gradle0.7+ then add this line:
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Your Key" />

Add the Google Play services version to your app's manifest
Edit your application's AndroidManifest.xml file, and add the
following declaration within the element. This embeds the version of
Google Play services that the app was compiled with.
You just need to add <meta-data> under <application> tag into your AndroidManifest.xml
....<application>
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
</application>

Google Maps NoClassDefFoundError

I'm working on an android project in which one of the activities includes a Maps view. I'm only after doing the code for displaying a simple Google Map but I bumped into this NoClassDefFoundError. I have checked some similar questions and tried the suggested solutions but still won't work. I have activated the Internet permision in the manifest file and the user library for the application. Does anyone have any suggestions on what might be the problem? Here's the activity code:
package com.mad.mylit;
import android.os.Bundle;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;
public class LocationsActivity extends MapActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.location);
}
#Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}
And here's my manifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mad.mylit"
android:versionCode="1"
android:versionName="1.0" android:installLocation="auto">
<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:icon="#drawable/icon"
android:label="#string/app_name" >
<uses-library android:name="com.google.android.maps"/>
<activity

android:label="#string/app_name"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
All of the activities are in the same package.

Try to get new maps API key with your personal keystore.

Have you recently updated your ADT plugin?
Here and here are some talks about same prblem..

SecurityException at starting intent of a new empty Activity

I have developed a little project using just one Activity, and now, I'm trying to add a new one, but, I recieve this error when I'm trying to launch the project on my device:
Running com.android.gl2jni/.TestActivity... 1> Starting: Intent {
cmp=com.android.gl2jni/.TestActivity } 1> 1>
java.lang.SecurityException: Permission Denial: starting Intent {
flg=0x10000000 cmp=com.android.gl2jni/.TestActivity } from null
(pid=2935, uid=2000) requires null
I'm not trying to call the new Activity, and I have developed an empty Activity to check why I can't launch the app.
This is my Manisfest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.gl2jni">
<uses-feature android:glEsVersion="0x00020000"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CAMERA"/>
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<application
android:label="#string/gl2jni_activity">
<!--main activity-->
<activity android:name=".GL2JNIActivity"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
android:launchMode="singleTask"
android:configChanges="keyboardHidden"
android:screenOrientation="landscape"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!--BT device list activity-->
<activity android:name=".TestActivity"
>

</intent-filter>
</activity>
<!--
<activity android:name=".BluetoothDeviceListActivity"
android:label="#string/select_device"
android:theme="#android:style/Theme.Dialog"
android:configChanges="keyboardHidden"
android:screenOrientation="landscape"
/>
-->
</application>
</manifest>
And this is the empty activity class:
package com.android.gl2jni;
import android.app.Activity;
import android.util.Log;
import android.os.Bundle;
public class TestActivity extends Activity {
#Override protected void onCreate(Bundle icicle) {
LogConsole.print( "HI, I AM TestActivity" );
}
}
I suppose that I have to modify something else more, but I don't know what...
Thanks in advance for the help.

You've specified an empty intent filter for TestActivity. An empty intent filter matches NO intents. Remove these lines from the block for TestActivity:
<intent-filter>
</intent-filter>
Also, in onCreate() of TestActivity you must call super.onCreate(), otherwise Android will crash it.
