Image is not uploading from MOTO G3

I am able to select an image from gallery , but it is not uploading . When I try to upload the image from file manager it is working.
Here is my code

this.filechoose.open().then((uri)=>{
this.filepath.resolveNativePath(uri).then((nativepath)=>
{
this.fileName = nativepath;
let options:FileUploadOptions={
fileKey:‘file’,
fileName:this.fileName,
chunkedMode:false,
headers:{}
}
var Opr = “addfile”;
this.fileTransfer.upload(nativepath,'https://www.voicetech-solutions.com/add_project.php?FileName=’+options.fileName+’&UserId=’+this.UserId+’&TempIdData=’+TempleId+’&Opr=’+Opr+’&Name=’+ProjectName+’&Amount=’+Amount,options,true)
.then((data)=>{
alert(JSON.stringify(data));
},(err)=>{
alert(JSON.stringify(err));
}
)
},(err)=>
{
alert(JSON.stringify(err));
})
},(err)=>
{
alert(JSON.stringify(err));
})
