Hi, I am saving a camera photo to my app’s data directory. It is necessary that the image is not deleted unless the app is deleted (that is, it persists cache cleans and any garbage collection done by the OS)
The path that is generated, is this: file:///var/mobile/Containers/Data/Application/1239C7A4-0564-4FDB-B72B-32477C6ADAC2/tmp/cdv_photo_011.jpg
I’m concerned by the “tmp” directory that is part of the path that is generated by cordova.file.dataDirectory . Can anyone help confirm that this directory won’t be removed/or if my code is correct: (The code is a mostly direct copy from this article)
// Get the data of an image
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());
});
} else {
var currentName = imagePath.substr(imagePath.lastIndexOf('/') + 1);
var correctPath = imagePath.substr(0, imagePath.lastIndexOf('/') + 1);
this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
}
console.log('Save to:' + correctPath + currentName);
this.selectedCategory.addItem({ notes: 'test', photo: correctPath + currentName });
}, (err) => {
this.presentToast('Error while selecting image.');
});
}
// Create a new name for the image
private createFileName() {
var d = new Date(),
n = d.getTime(),
newFileName = n + ".jpg";
return newFileName;
}
// Copy the image to a local folder
private copyFileToLocalDir(namePath, currentName, newFileName) {
this.file.copyFile(namePath, currentName, cordova.file.dataDirectory, newFileName).then(success => {
this.lastImage = newFileName;
}, error => {
this.presentToast('Error while storing file.');
});
}
