清除数据并重新启动应用程序的Andr​​oid [英] Clear data and restart app android

问题描述

我要清除数据，并在我的应用程序重新启动应用程序。为此，我已经使用下面的code。然而，它似乎并没有工作。请帮助我！

I want to clear data and restart app in my app. For this I've used the code below. However, it doesn't seem to work. Please help me out !

deleteDatabase(Universal.database_name);
Intent i = getBaseContext().getPackageManager().getLaunchIntentForPackage( getBaseContext().getPackageName() );
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK );
startActivity(i);

编辑：我看不出有什么效果和应用程序简单地用数据完全保留重新启动

I see no effect and the app simply restarts with data absolutely retained !

推荐答案

**此活动说明不了什么;相反，它重新启动了Android程序* /

** This activity shows nothing; instead, it restarts the android process */

public class AppRestartActivity extends Activity {
    // Do not forget to add it to AndroidManifest.xml
    // <activity android:name="your.package.name.AppRestartActivity"/>
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        System.exit(0);
    }
    public static void doRestart(Activity anyActivity) {
        anyActivity.startActivity(new Intent(anyActivity.getApplicationContext(), MagicAppRestart.class));
    }
}
