Question

当我点击运行时，apk曾经在我的手机上自动启动，但现在它在开发者选项上保持不变，

一旦我点击在eclipse上运行，它会在控制台上显示以下内容：

[2014-03-11 16:26:36 - MyFirstApp] ------------------------------
[2014-03-11 16:26:36 - MyFirstApp] Android Launch!
[2014-03-11 16:26:36 - MyFirstApp] adb is running normally.
[2014-03-11 16:26:36 - MyFirstApp] No Launcher activity found!
[2014-03-11 16:26:36 - MyFirstApp] The launch will only sync the application package on     
[2014-03-11 16:26:36 - MyFirstApp] Performing sync
[2014-03-11 16:26:36 - MyFirstApp] Automatic Target Mode: Unable to detect device             
[2014-03-11 16:26:38 - MyFirstApp] Uploading MyFirstApp.apk onto device 'EP73226B61'
[2014-03-11 16:26:38 - MyFirstApp] Installing MyFirstApp.apk...
[2014-03-11 16:26:41 - MyFirstApp] Success!
[2014-03-11 16:26:41 - MyFirstApp] \MyFirstApp\bin\MyFirstApp.apk installed on device
[2014-03-11 16:26:41 - MyFirstApp] Done!

但是我说我手机上没有任何东西，然后我尝试其他方法，比如将apk放入我的下载文件并安装它，它说，Do you want to install an update to this existing application? Your existing data will not be lost. it does not require any special access.一旦我点击安装，它显示应用程序安装并离开我的两个按钮，完成和打开。但是＆＃34;开放＆＃34;按钮是不可点击的

有线，我无法在内部存储和SD卡中找到它，甚至在我的安装应用列表中也找不到。

我的设定单击USB调试点击后保持清醒

这是我的清单

<?xml version="1.0"   encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myfirstapp"
android:versionCode="1"

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

    <activity

            android:value="com.example.myfirstapp.MainActivity" />
    </activity>
</application>

</manifest>

检查您的AndroidManifest.xml文件。它应该包含这样的内容：

<application details omitted>
    <activity  details omitted>
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
       </intent-filter>
    </activity>
</application>

如果你没有像上面那样的意图过滤器，Android就不知道要启动你的应用程序的活动。
