Apps Parcelable Object return BadParcelableException: ClassNotFoundException when getParcelableExtra

I have a problem when I write pracelable object and receive from another application that I wrote. Everytime when I tried to get the object it always turned out to be BadParcelableException: ClassNotFoundException when unmarshalling.

I've been looking around and wonder if it turned out bad when I send to another application. Or it's simply I had error in my codes.

Please tell me where did I go wrong.

Note: please understand that I have been looking for answer for this for a while and I still can't find where is my problem is. I looked up many people's code and tested out many times but still can't get my app right. So that is why I am here to ask help. If some people still think I am a lazy noob, I guess I am too lazy for some people to draw that conclusion. I should reconsider of my action again.

My situation is:
I wrote 2 apps and one is sending a parcelable object to another application. First app it's working correctly to send the object to another. However, as the second app receive it, it goes wrong and gives out the BadParcelableException as I run the process. I am not using bundle because I saw many examples that it is not necessary to do so. If I have been wrong please correct me. Both app contains the ParcelableObject class.

My send lines in first app:
Java: 
Intent intent = new Intent();
ParcelableObjectmyObject = newParcelableObject();
myObject = newParcelableObject(result_name, resut_lv, result_race,
result_job, result_nation, result_guild, result_mission); 
intent.putExtra("ACTION_DATA_TRANSFER",myObject);
intent.setClassName(target_app, target_app+".ReceiveMain"); 
startActivity(intent);

First app Manifest:
Java: 
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="abc.com.android.send_app"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".SendMain"
            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>

</manifest>

My receive lines in second app:
Java: 
ParcelableObjectmyObject = newParcelableObject();
myObject = getIntent().getParcelableExtra("ACTION_DATA_TRANSFER");//always crashed at this line 

if(getIntent().hasExtra("ACTION_DATA_TRANSFER")){
Log.w("****CHECKING****",myObject.getName());
item1.setText("The Character's name is: "+myObject.getName());
}else{ 
Toast.makeText(getApplicationContext(),"There is not data passed yet",
Toast.LENGTH_LONG).show();
}

Second app Manifest:
Java: 
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="def.com.android.receive_app"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".ReceiveMain"
            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>

</manifest>

This is my ParcelableObject class that implements Parcelable:

Your parcelable object is in a different package to your main application. Why is that? This package didn't get included in the deployment bundle (apk), so at run time the class can't be found.
You need to move the ParcelableObject class into package def.com.android.receive_app, or create a new parcelable object class in this package.

oh I see....

Thank you for clearing my understanding.
My original intention is to send a parcelable object to another application.

I've read some documents that indicates that transfer between applications has go by services and with help of AIDL. Well at least I know this is a dud option.

Thanks a lot for the answers
