Question

I have specified a receiver in the manifest like so ..

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

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_SMS"/>

<application android:label="@string/app_name"
             android:icon="@drawable/ic_launcher" android:enabled="true">

    <service android:name="MyService" 
             android:exported="true"
             android:process=":different" 
             android:enabled="true">
        <intent-filter>
            <action android:name="com.me.MyService">
            </action>
        </intent-filter>
    </service>

    <receiver android:exported="true" 
              android:name="MySMSBroadcastReceiver" 
              android:enabled="true">
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
        </intent-filter>
    </receiver>
</application>

If I test this on an Android Froyo device (emulator or real) this works as I expect. The MySMSBroadcastReceiver.onReceive(…) is being called when the device receives an SMS.

However if I install this on a 4.0 or 4.1 device (either emulator or a real device) nothing happens on an incoming message. No errors, no nothing. I also changed the properties for the project to target a 4.0 or 4.1 device specifically and re-installed it but that makes no difference.

After your application is installed, the user need to launch an activity of yours manually before any of your BroadcastReceivers will have an effect, as of Android 3.1.
