问题描述

I am trying to upload an image from my image gallery into my firebase storage folder with ionic. This works fine for ios emulator but does not work on android. What might be the problem ? What should I check ?

//这是默认选项
$ scope.capturarFoto = function（type）{
var opcionesCaptura = {
destinationType：Camera.DestinationType.FILE_URI，
sourceType：Camera.PictureSourceType [type.toUpperCase（）]，
};

// this is the default options $scope.capturarFoto = function (type) { var opcionesCaptura = { destinationType: Camera.DestinationType.FILE_URI, sourceType: Camera.PictureSourceType[type.toUpperCase()], };

    $cordovaCamera.getPicture(opcionesCaptura)
        .then(procesarImagen, procesarError);
};

function procesarImagen(pathImagen) {
    var directorioFuente = pathImagen.substring(0, pathImagen.lastIndexOf('/') + 1),
        archivoFuente = pathImagen.substring(pathImagen.lastIndexOf('/') + 1, pathImagen.length),
        nombreParaGuardar = new Date().valueOf() + archivoFuente;

    $cordovaFile.readAsArrayBuffer(directorioFuente, archivoFuente)
        .then(function (success) {
            var blob = new Blob([success], {type: 'image/jpeg'});
            enviarFirebase(blob, nombreParaGuardar);
        }, function (error) {
            console.error(error);
        });
}


function enviarFirebase(file, nombre) {
    var storageRef = firebase.storage().ref();
    var uploadTask = storageRef.child('images/' + nombre).put(file);
    uploadTask.on('state_changed', function (snapshot) {
        console.info(snapshot);
    }, function (error) {
        console.error(error);
    }, function () {
        var downloadURL = uploadTask.snapshot.downloadURL;
        console.log(downloadURL);

推荐答案

我也是Cordova的新手，但我相信您需要相机功能才能确保您的设备准备就绪：

I am also new to Cordova but I believe for Camera functionality you would need to ensure that your device is ready:

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
    console.log(navigator.camera);

    /* Here you can have $scope.choosePhoto = ... */

}

我确定这是你必须采取的方法。试试看，看看它是否有效。

I'm sure this is the approach you'd have to take. Try that and see if it works.
