Answer 1

It is very simple, It is totally based on the event occuraing. Let me give you a logic for this.

• Create a BroadcastReceviver which will check for the incoming and outgoing calls.
• Create a method which will record the voice for both the event.
• Whenever the BroadcastReceiver fires just call that method init.
• Done.

eg

Declare receiver in AndroidManifest

<receiver android:name=".CallRecoderBroadcast">   
    <intent-filter>
        <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>

Give read phone state permission in AndroidManifest

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
