マニフェストファイルには、アプリランチャーとして1つのアクティビティが必要です...

<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >

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

</activity>

起動アクティビティを定義する必要があると思います。

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

    <uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        </activity>
    </application>

</manifest>

あなたの活動タグに挿入<category android:name="android.intent.category.LAUNCHER" />してください、これは私が推測する問題の世話をします。
