Installation error: INSTALL_FAILED_OLDER_SDK in eclipse

I have an unexpe`ted problem with my Android project. I have a real android device with ice_cream sandwich installed. My app was working fine during the development but after I added a class to the project, I got an error:
Installation error: INSTALL_FAILED_OLDER_SDK

The problem is that everything is good in the manifest file. The minSdkversion is 8.
Here is my manifest file:

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

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

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="zabolotnii.pavel.timer.TimerActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

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

</manifest>


I don't know, if there is any need to attach the new class ,but I didn't any changes to other code that should led to this error:

Answer

Remove the space from your targetSdkVersion value. Change

android:targetSdkVersion="18 "

to

android:targetSdkVersion="18"

The app installer has different logic (source) for versions given as strings such as "18 " as opposed to versions given as integers such as "18". You really need the value to be there as an integer.
