Can I Modify Sms_body Before Sending Sms With Built-in Sms Application?

I know that we can send SMS via built-in SMS app in this way - Intent sendIntent = new Intent(Intent.ACTION_VIEW); sendIntent.setData(Uri.parse('sms:')); sendIntent.putExtra('sms

Solution 1:

This is not possible, since SmsManager is part of frameworks. You cannot hijack it.

Edit: What you could do is change your app manifest to recieve ACTION_VIEW and uri sms: just like default messaging app and then when launched will change the body and launch the default messaging app.

Edit: Add below intent filter to your app and then "sms_body" extra from the intent and rebroadcast it this time by createChooser

<intent-filter><actionandroid:name="android.intent.action.VIEW" /><actionandroid:name="android.intent.action.SENDTO" /><categoryandroid:name="android.intent.category.DEFAULT" /><categoryandroid:name="android.intent.category.BROWSABLE" /><dataandroid:scheme="sms" /><dataandroid:scheme="smsto" /></intent-filter>
