Change Android's default programs?

If i'm developing an alternative Android SMS application, is there any way to re开发者_JS百科place the default sms application with my, so that my app receives the incoming sms message?

you just have to set a higher priority for your broadcast receiver like this. For example 100

<intent-filter android:priority="100">
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>

Then you have to call abortBroadcast(); when you want it to stop if you dont want it to propagate. This only works for orderedbroadcasts.

You cannot enforce your app on the users. As Corey mentioned users will have to switch off sms notifications in the default app to not getting the notification twice.
