使用　finishAffinity()　方法即可．例如：

// 先清空缓存

SharedPreferences userSettings = getSharedPreferences("cache", MODE_PRIVATE);

SharedPreferences.Editor editor = userSettings.edit();

editor.clear();

editor.commit();

settings = App.application.getSharedPreferences(Constants.REFERENCE_NAME, 0);

SharedPreferences.Editor referEditor = settings.edit();

referEditor.clear();

referEditor.commit();

// 就是这一句．

finishAffinity();

Intent intent = new Intent(this, MainActivity.class);

startActivity(intent);
