Java – How to add SMS in inbox and sent messages in android programmatically

"As of Android 1.6, incoming SMS message broadcasts (android.provider.Telephony.SMS_RECEIVED) are delivered as an "ordered broadcast" — meaning that you can tell the system which components should receive the broadcast first."

This means that you can intercept incoming message and abort broadcasting of it further on.

In your AndroidManifest.xml file, make sure to have priority set to highest:

<receiver android:name=".receiver.SMSReceiver" android:enabled="true">
    <intent-filter android:priority="1000">
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

In your BroadcastReceiver, in onReceive() method, before performing anything with your message, simply call abortBroadcast();

EDIT: As of KitKat, this doesn't work anymore apparently.

EDIT2: More info on how to do it on KitKat here:

I'm assuming you're using XML layout.

<TextView  
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:gravity="center"
    android:text="@string/**yourtextstring**"
/>

You can also use gravity center_vertical or center_horizontal according to your need.

and as @stealthcopter commented in java: .setGravity(Gravity.CENTER);
