Sun, 02 May 2010 00:00:00 +0200

Sound recording and playback is really simple using the MediaRecorder and MediaPlayer classes .. see the example below ..

Sample App

First some layout .. a button to start/stop recording and a button to play the recorded stuff (main.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
	android:id="@+id/output"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text=""
    />
<Button android:text="@+string/record" android:id="@+id/btRecord" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
<Button android:text="@+string/play" android:id="@+id/btPlay" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
</LinearLayout>

Adjusting the externalized strings in the strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">Soundrecorder Tutorial</string>
	<string name="record">Record!</string>
	<string name="play">Play</string>
</resources>
