/** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {

 <uses-sdk android:minSdkVersion="4" />

  <application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".SendBroadcast"
              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=".ToastDisplay">

    <intent-filter>
        <action android:name="com.unitedcoders.android.broadcasttest.SHOWTOAST">  </action>
    </intent-filter>
  </activity>

  </application>
  </manifest>

Answer 1

you have not registered your Receiver in Manifest :registered as

<receiver android:name="receiver">
<intent-filter>
<action
android:name="com.unitedcoders.android.broadcasttest.SHOWTOAST"/>
</intent-filter>
</receiver>
