- add reference to media-scan.js in HTML5 Markup
- Add reference to Angularjs . This is a Angularjs based cordova project
- After reference has been added then kindly add cordova.file.media as a DI
var app = angular.module("myApp",["cordova.file.media"]);
Then in a Controller Inject Media
app.controller('globalCtrl', ['Media','$q',function (Media,$q)
{
});To call the Media Scanner.
var url = [
"file:///storage/emulated/0/",
"file:///mnt/sdcard/"
];
fileType = ["mp3"];
function permissionRespfunction(resp)
{
if(resp=="GRANTED")
{
//load Loader
var respArray =[];
var file = Media.scan(url,fileType);
file.then(function(resp)
{
if(resp.length!=0)
{
log("Before Removing Duplicates");
log(resp);
$scope.fileScan = Media.removeDuplicates(resp,"name"); //remove duplicaes based on Name
log("After Removing Duplicates");
log($scope.fileScan);
}
else
{
log("No Media Found...Please Scan Again");
Media.permission();
}
});
}
else if(resp=="NOT_REQUESTED")
{
Media.permission(permissionRespfunction); //Func Ends
}
else if(resp=="DENIED")
{
Media.permission(permissionRespfunction); //Func Ends
}
else if(resp=="DENIED_ALWAYS")
{
Media.permission(permissionRespfunction); //Func Ends
}
else if(resp=="DENIED_ALWAYS")
{
Media.permission(permissionRespfunction); //Func Ends
}
}
Media.permission(permissionRespfunction); //Func Ends
-
Media.permission(cb) : this is a async func which check for permission if on marshmallow 6.0 and above. For <6.0 it will not ask for permission. cb is a callback function.
-
var file = Media.scan(url,fileType) : It is a promises which return all the files based on the file Type. Kindly refer to the above example. The fileType is a file extension as an array. for url please refer to Android File System.
-
Media.removeDuplicates : this function removes duplicates from the promise returned from Media.scan(url,fileType)
