科尔多瓦插件媒体不从本地 URI 播放

Question

Trying to play audio files from the external storage of phone.

Went through this plugin first finding the URI for a particular mp3 file. Then passed that to the cordova-plugin-media instance.

// find music file URI from the sdcard
new ExternalStorageSdcardAccess( fileHandler ).scanPath( "file:///storage/C67A-18F7/Music/" );
function fileHandler( fileEntry ) {
    // console.log( fileEntry.name + " | " + fileEntry.toURL() );
}    

// create a button instance
let mbutton = new Button({
  centerX: 0, top: [fbutton,100],
  text: 'play music'  
}).appendTo(ui.contentView);    

// call the play media function from the button
mbutton.on('select', () => {
    // load and play the music:
    playAudio("file:///storage/C67A-18F7/Music/demo/testSound.mp3")

});    

function playAudio(url) {
    // Play the audio file at url
    var my_media = new Media(url,
        // success callback
        function () {
            console.log("playAudio():Audio Success");
        },
        // error callback
        function (err) {
            console.log("playAudio():Audio Error: " + err.code + err.message);
        },
        // status callback
        function (status) {
            console.log("playAudio():Audio Status: " + status);
        }
    );
    // Play audio
    my_media.play();
    my_media.setVolume('1.0');
}

I checked the adb for log. This is what I got specifically hitting those buttons - http://paste.ubuntu.com/25767292/

Answer 1

I am using Capacitor with an ionic react project and was able to get cordova-plugin-media playing local files by using it in conjunction with cordova-plugin-file . I am the ionic-native wrappers, but I think its the same code here.

NOTE: iOS requires you to remove 'file://' and Android does not.

    const finishedFilePath = `${File.applicationDirectory}public/assets/audio/file.mp3`;
const hybridTransitionAudioFile = Media.create(isPlatform('ios') ? transitionFilePath.replace('file://', '') : transitionFilePath);
hybridTransitionAudioFile.play();

HTML PART for audio src

        <audio id="successSound" src="/android_asset/www/audio/correct.mp3" type="audio/mpeg"></audio>
        <audio id="errorSound" src="/android_asset/www/audio/error.mp3" type="audio/mpeg" ></audio>
    </body>
</html>

Example of my version that works i hope there is help in it

playAudio("errorSound");


var my_media = null;
var mediaTimer = null;

function playAudio(id) {
    var audioElement = document.getElementById(id);
    var src = audioElement.getAttribute('src');
    // Create Media object from src
    my_media = new Media(src, onSuccess, onError);

    // Play audio
    my_media.play();

    // Update my_media position every second
    if (mediaTimer == null) {
        mediaTimer = setInterval(function() {
            // get my_media position
            my_media.getCurrentPosition(
                // success callback
                function(position) {
                    if (position > -1) {
                        setAudioPosition((position) + " sec");
                    }
                },
                // error callback
                function(e) {
                    console.log("Error getting pos=" + e);
                    setAudioPosition("Error: " + e);
                }
            );
        }, 1000);
    }
}

function setAudioPosition(position) {
    document.getElementById('audio_position').innerHTML = position;
}


// onSuccess Callback
//
function onSuccess() {
}

// onError Callback
function onError(error) {
    switch(error.code){
        case MediaError.MEDIA_ERR_ABORTED:
        alert('MEDIA_ERR_ABORTED code: '    + error.code);
        break;
        case MediaError.MEDIA_ERR_NETWORK:
        alert('MEDIA_ERR_NETWORK code: '    + error.code);
        break;
        case MediaError.MEDIA_ERR_DECODE:
        alert('MEDIA_ERR_DECODE code: '    + error.code);
        break;
        case MediaError.MEDIA_ERR_NONE_SUPPORTED:
        alert('MEDIA_ERR_NONE_SUPPORTED code: '    + error.code);
        break;
    }
}
