<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.myalert"     android:versioncode="1"     android:versionname="1.0" >      <uses-sdk         android:minsdkversion="8"         android:targetsdkversion="17" />      <uses-permission android:name="android.permission.internet" />     <uses-permission android:name="android.permission.access_fine_location" />     <uses-permission android:name="android.permission.access_mock_location" />     <uses-permission android:name="android.permission.access_coarse_location" />     <uses-permission android:name="android.permission.vibrate" />      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name="com.example.myalert.mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>         <activity              android:name="proximityreceiver">         </activity>     </application>  </manifest> 

you have not set receiver in manifest, "proximityreceiver" not activity receiver. try this.

 <receiver android:name="proximityreceiver" >         <intent-filter>             <action android:name="com.example.myalert" />         </intent-filter>   </receiver> 

cheers.
