Sound manipulation using MediaPlayer – Android dev

Another tutorial for MobileSIG – how can you manipulate an MP3 sound file to play, pause and stop. Unfortunately, I still having some problems with PAUSE. I’ll figure out letter. Basically this example may PLAY and STOP a MP3 sound file source.

This is a half day project development, sorry for any inconvenient.

The application screenshot;

APP - Baca fatihah bersama ustaz Don

What the application does – basically it has the verses in Arabic, and the recitation. Click “>” to hear the recitation, click “henti” to stop. “II” is to pause (not yet functioning). Tested on Samsung Galaxy S and HTC Wildfire only.

The project setting;

The al-Fatihah recitation is in assets (01fatihah.mp3), the images are in res/drawable-mdpi (fatihah.png is the verses in Arabic).

The User Interface (main.xml);

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical" android:background="@drawable/islamicbg">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:keepScreenOn="true" android:text="al-Fatihah (1-7)"/>
<ImageView android:layout_height="wrap_content" android:src="@drawable/fatihah"
android:id="@+id/imageView1" android:layout_width="wrap_content"></ImageView>
<TableLayout android:layout_height="wrap_content" android:id="@+id/tableLayout1"
android:layout_width="fill_parent">
<TableRow android:layout_width="fill_parent" android:id="@+id/tableRow1" android:layout_height="fill_parent"
android:layout_gravity="center_vertical">
<Button android:text=" > " android:id="@+id/btnplay" android:layout_width="wrap_content"
android:layout_column="0" android:layout_height="wrap_content" />
<Button android:text=" || " android:id="@+id/btnpause" android:layout_width="wrap_content"
android:layout_column="1" android:layout_height="wrap_content" />
<Button android:text="henti" android:id="@+id/btnstop" android:layout_width="wrap_content"
android:layout_column="2" android:layout_height="wrap_content" />
</TableRow>
</TableLayout>

</LinearLayout>


The source code;
