ionic3兼容android,不允许加载本地资源：ionic 3 android

我正在使用ionic 3

android build apk并尝试从文件中添加图像：///storage/emulated/0/data/io.ionic.vdeovalet/cache/image.jpeg

takePicture(sourceType) {

try {

// Create options for the Camera Dialog

var options = {

quality: 100,destinationType: this.camera.DestinationType.FILE_URI,encodingType: this.camera.EncodingType.JPEG,sourceType: sourceType,};

this.camera.getPicture(options).then((imagePath) => {

// Special handling for Android library

if (this.platform.is('android') && sourceType ===

this.camera.PictureSourceType.PHOTOLIBRARY) {

this.filePath.resolveNativePath(imagePath)

.then(filePath => {

let correctPath = filePath.substr(0,filePath.lastIndexOf('/') + 1);

let currentName = imagePath.substring(imagePath.lastIndexOf('/') + 1,imagePath.lastIndexOf('?'));

this.copyFileToLocalDir(correctPath,currentName,this.createFileName());

this.lastImage = filePath;

});

} else {

var currentName = imagePath.substr(imagePath.lastIndexOf('/') + 1);

var correctPath = imagePath.substr(0,imagePath.lastIndexOf('/') + 1);

this.copyFileToLocalDir(correctPath,this.createFileName());

}

},(err) => {

this.presentToast('Error while selecting image.');

});

} catch (e) {

console.error(e);

}

}

错误：不允许加载本地资源
