通过Eclipse在物理Android设备上安装HelloWorld应用程序。我怎么在电话里找到它？

Eclipse中的控制台说：

[2014-03-10 17:46:08 - MyFirstApp] ------------------------------
[2014-03-10 17:46:08 - MyFirstApp] Android Launch!
[2014-03-10 17:46:08 - MyFirstApp] adb is running normally.
[2014-03-10 17:46:08 - MyFirstApp] No Launcher activity found!
[2014-03-10 17:46:08 - MyFirstApp] The launch will only sync the application package on the device!
[2014-03-10 17:46:08 - MyFirstApp] Performing sync
[2014-03-10 17:46:17 - MyFirstApp] Uploading MyFirstApp.apk onto device 'TA88307T9S'

这是在从在线导入Hello World应用程序之后。现在我希望在我的手机上找到一个应用图标来启动它，但我找不到。如何启动应用程序

在Merlevede的回答之后，我的清单xml文件现在看起来像这样：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myfirstapp"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

<intent-filter android:label="@string/app_name">
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:debuggable="true"
    android:theme="@style/AppTheme" >

</application>

</manifest>

但问题依然存在

问题出在您的Android清单xml文件中。您的主要活动（要么是

Main

操作，要么是

LAUNCHER

类别）缺少其中一些行

找不到启动程序活动

正如日志所说，您没有启动程序活动。要解决此问题，请根据您的要求将任何活动设置为laucher
