【问题描述】：

当我按下 home button 或 button to see what applications are running 时 - 我的应用程序关闭。我试图添加onPause()、onResume() 等，但什么也没有。它发生在重构后的一段时间内。

【问题讨论】：

请发布您的代码和错误日志！
长按还是长按？两者都执行不同的操作。
您是否在 onPause() 中添加了一个 Log 以检查您的应用程序是否未执行 onPause() ？添加你的 onPause () Log.i("onPause","onPause starts !");
请张贴你的日志猫
简单按下后。时间不长。

【解决方案1】：

我发现了问题。问题是未在 AndroiManifest.xml 中指定启动器活动的标签

<activity
            android:name="com.test.MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter android:label="@string/app_name" >
                <action android:name="android.intent.action.MAIN" />

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