Do you first execute the class for the name of the application or the class for name in the activity?

Today, we found the procedure entrance, and I've got two name, and I've written a test program, roughly as follows:

See Mainfest.xml first.

<application

Android:allowbackup= "true"
android:icon= "@drawable/ic_launcher"
Android:name= "Com.example.test1.app"
Android:label= "@string/app_name"
Android:theme= "@style/apptheme" >
<activity
Android:name= "Com.example.test1.MainActivity"
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>

K See app

Package com.example.test1;


Import android.app.Application;
Import Android.os.Bundle;
Import Android.util.Log;


public class App extends application{
public void OnCreate () {

Super.oncreate ();
LOG.D ("TT", "Application");
}


}

See activity as follows

public class Mainactivity extends Activity {


@Override
protected void OnCreate (Bundle savedinstancestate) {
Super.oncreate (savedinstancestate);
Setcontentview (R.layout.activity_main);
LOG.D ("TT", "activity");
New app ();

}

｝

Finally, we look at the log file is clear:

10-28 15:40:54.915:d/tt (4116): Application

10-28 15:40:55.525:d/tt (4116): Activity

This means that application's name corresponds to the class that was created when the program was installed .

Then I opened the second time as follows:

There is only one message

Android.app.Application
Base class for those who need to maintain global application state. You can provide your own implementation by specifying it name in your androidmanifest.xml ' s <application> tag, whic H would cause that class to being instantiated for if the process for your application/package is created.
