Android - How to play the audio files directly from res/raw folder?

To play audio files directly from the res/raw folder in Android, you can use the MediaPlayer class. Here's a simple example demonstrating how to play an audio file from the res/raw folder:

  1. Place Audio File in res/raw: Copy your audio file (e.g., audio.mp3) to the res/raw folder in your Android project.

  2. Create MediaPlayer in Activity or Fragment: In your activity or fragment, create a MediaPlayer instance and set the audio file using the resource identifier (R.raw.audio).

    import android.media.MediaPlayer; import android.os.Bundle; import android.view.View; import android.widget.Button; public class YourActivity extends AppCompatActivity { private MediaPlayer mediaPlayer; private Button playButton; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); playButton = findViewById(R.id.playButton); // Initialize MediaPlayer with the audio file from res/raw mediaPlayer = MediaPlayer.create(this, R.raw.audio); playButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // Check if the MediaPlayer is already playing; if so, stop it if (mediaPlayer.isPlaying()) { mediaPlayer.stop(); mediaPlayer.reset(); playButton.setText("Play"); } else { // Start playing the audio mediaPlayer.start(); playButton.setText("Stop"); } } }); } @Override protected void onDestroy() { super.onDestroy(); // Release the MediaPlayer resources if (mediaPlayer != null) { mediaPlayer.release(); } } }

  3. XML Layout (activity_main.xml): Create a layout file with a Button for controlling playback.

    <!-- activity_main.xml --> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="16dp" tools:context=".YourActivity"> <Button android:id="@+id/playButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Play" /> </RelativeLayout>

In this example, the MediaPlayer is initialized using the MediaPlayer.create method, which takes a context and the resource identifier of the audio file (R.raw.audio). The playButton is used to start and stop the playback.

Remember to release the MediaPlayer resources in the onDestroy method to avoid memory leaks.

Make sure to replace YourActivity and audio.mp3 with your actual class name and audio file name.
