How to merge two or more mp3 audio file in android?
<p>I'm trying to merge mp3 audio files But not successful. </p>

<p>Here is my code.</p>

<pre><code>public static void meargeAudio(List&lt;File&gt; filesToMearge)
{


    while (filesToMearge.size()!=1){

        try {
            FileInputStream fistream1 = new FileInputStream(new File(filesToMearge.get(0).getPath()));  //(/storage/emulated/0/Audio Notes/1455194356500.mp3) first source file
            FileInputStream fistream2 = new FileInputStream(new File(filesToMearge.get(1).getPath()));//second source file

            File file1 = new File(filesToMearge.get(0).getPath());
            boolean deleted = file1.delete();
            File file2 = new File(filesToMearge.get(1).getPath());
            boolean deleted1 = file2.delete();

            SequenceInputStream sistream = new SequenceInputStream(fistream1, fistream2);
            FileOutputStream fostream = new FileOutputStream(new File(filesToMearge.get(0).getPath()),true);//destinationfile

            int temp;

            while ((temp = sistream.read()) != -1) {
                // System.out.print( (char) temp ); // to print at DOS prompt
                fostream.write(temp);   // to write to file
            }

            filesToMearge.add(0,new File(filesToMearge.get(0).getPath()));
            filesToMearge.remove(1);
            filesToMearge.remove(1);


            fostream.close();
            sistream.close();
            fistream1.close();
            fistream2.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}
</code></pre>

<p>e.g </p>

<p>firstFileSize =12kb</p>

<p>secondFileSize =10kb</p>

<p>finalfileSize=22kb</p>

<p>Size is accurate But sound is missing</p>

<p>No error but in result i found finalfile contains only first file audio second file audio is missing.</p>

<p>Don't know what is the issue.if any one know the solution help me.</p>

<p>Thanks </p>
