MediaRecorder IOException: prepare failed

Question

I want to use MediaRecorder to record voice, my code is:

 public void record(View v) {
       Log.d(TAG, \"record\");

    this.mediaRecorder.setAudioChannel         


        

Answer 1

This is a big problem but has a very small solution

In most cases, the filename that we get from this.file.getAbsolutePath() contains file:/// as a prefix

    ////////////////////////////////////////////////* INCORRECT CODE */
    this.mediaRecorder.setOutputFile(this.file.getAbsolutePath());
    /*the above line sets a file url beginning with a "file:///"
    //however, since this setOutputFile requires us to send a
    //string referring to the uri, we will have to get rid of the
    //"file:///" and simply write the uri */
    ////////////////////////////////////////////////* CORRECTED CODE BELOW */
    this.mediaRecorder.setOutputFile(this.file.getAbsolutePath().substring(8));
    /*the above line of code extracts the string uri eliminating
    // file:/// */

Hope you find this answer helpful
