Hello,
i want to delete all files inside the cache folder because i want my users to be able to easely free the memory in the settings page of my app. I googled for a while and couldn’t find a proper guide.
I’m sure there’s an easy way using the Ionic Native File plugin?
Hi @Fieel
I think everything you need is in the file plugin:
There’s a similar question w/solution on StackOverflow: Ionic 2: Get size cache directory and clear it
Thanks! The File native plugin can indeed do the job, here’s my solution:
this.file.listDir(this.file.cacheDirectory,'org.chromium.android_webview').then((result)=>{
console.log('files in org.chromium.android_webview directory: ', result);
console.log('Started deleting files from cache folder!');
for(let file of result){
if(file.isFile == true){
this.file.removeFile(this.file.cacheDirectory+'/org.chromium.android_webview/', file.name).then( data => {
console.log('file removed: ', this.file);
data.fileRemoved.getMetadata(function (metadata) {
let name = data.fileRemoved.name;
let size = metadata.size ;
let fullPath = data.fileRemoved.fullPath;
console.log('Deleted file: ', name, size, fullPath) ;
console.log('Name: ' + name + ' / Size: ' + size) ;
}) ;
}).catch( error => {
file.getMetadata(function (metadata) {
let name = file.name ;
let size = metadata.size ;
console.log('Error deleting file from cache folder: ', error) ;
console.log('Name: ' + name + ' / Size: ' + size) ;
}) ;
});
}
}
}) ;
