Android重啟應用程式代碼

[java]
Intent i = getBaseContext().getPackageManager() 
        .getLaunchIntentForPackage(getBaseContext().getPackageName()); 
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
startActivity(i); 

  Intent i = getBaseContext().getPackageManager()
    .getLaunchIntentForPackage(getBaseContext().getPackageName());
  i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
  startActivity(i);

ps:

getApplicationContext()返回應用的上下文，生命週期是整個應用，應用摧毀它才摧毀

Activity.this的context 返回當前activity的上下文，屬於activity ，activity 摧毀他就摧毀

 getBaseContext()  返回由建構函式指定或setBaseContext()設定的上下文
