exit android application programmatically

问题:

I have two activities, the first is a splash activity. I would like to know how to exit the application from the second activity to the homepage. I've used this method it works BUT it takes to the launcher.

public void AppExit() 
{

    this.finish();
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_HOME);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);


}

回答1:

Whenever you wish to exit all open activities, you should press a button which loads the first Activity that runs when your application starts then clear all the other activities, then have the last remaining activity finish. to do so apply the following code in ur project

Intent intent = new Intent(getApplicationContext(), FirstActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);

The above code finishes all the activities except for FirstActivity. Then we need to finish the FirstActivity's Enter the below code in Firstactivity's oncreate

if (getIntent().getExtras() != null && getIntent().getExtras().getBoolean("EXIT", false)) {
    finish();
}

and you are done....

From Finish all activities at a time

when you want to close your application, you can call

finishAffinity();

or if you want close it in background also you should write,

android:excludeFromRecents="true"

in AndroidManifest :

       <activity
        android:name="com.smart.remote.main.SplashActivity"
        android:configChanges="orientation|keyboardHidden"
        android:screenOrientation="portrait" 
        android:excludeFromRecents="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

To finish an activity or exit the app, try this..

public void exitApp(View v)
{

finish();

}

& use this if for whatever you select to exit the app.

android:onClick="exitApp"

This is the cleanest way I have come across:

moveTaskToBack(true);
finish();
