[Eclipse] Application does not specify API level

Question

I am just beginning to use Eclipse for Android applications. I have installed Eclipse 3.5.2 and Java 5 AVD is Android 2.1 API 7

My initial Hello Android program ran fine but will not run again.

getting the following error:

[2010-07-25 09:47:31 - HelloAndroid] WARNING: Application does not specify an API level requirement!
[2010-07-25 09:47:31 - HelloAndroid] Device API version is 7 (Android 2.1-update1)

searched the forums but could only find a refernece to manifest file to be sure following was set:

<uses-sdk android:minSdkVersion="3" />

my manifest file does not contain that line:

 <?xml version="1.0" encoding="utf-8" ?> 
 <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.helloandriod" android:versionCode="1" android:versionName="1.0">
     <application android:icon="@drawable/icon" android:label="@string/app_name">
         <activity android:name=".HelloAndroid" 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 have checked the adv mgr and it is set to 7 In Eclipse i went to properties -> Android and set it to 7

get same warnings

Answer 1

Well, if Eclipse is, for whatever reason, not generating that line for you, by all means you can add it yourself.

Add the line:
<uses-sdk android:minSdkVersion="3" />

to your manifest, right before the ending manifest tag.

Answer 2

You should also include

<uses-sdk android:minSdkVersion="7" />

in your manifest file, if it is not already there. It's not clear from your question, but seems that it isn't.
