unable to delete file in Android lollipop and higher

I am trying following code 

String Data = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.DATA));

     File file = new File(Data);
    if (file != null && file.exists()) {
                           // delete it
                           Toast.makeText(FileEditorDialog.this, "deleted not null",
                                   Toast.LENGTH_LONG).show();
                       }


                       boolean deleted = file.delete();


                       if (deleted) {
                           Toast.makeText(FileEditorDialog.this,
                                   "Successfully Deleted", Toast.LENGTH_LONG).show();

                           sendBroadcast(new Intent(
                                   Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
                                   Uri.parse("file://"
                                           + Environment.getExternalStorageDirectory())));
                           finish();
                       }

This code works in Android jelly bean but not in Android lollipop how can we delete files in Android lollipop?

You have to get Runitme permissions from user in android 6.0 only declaring them manifest is not enough.

Look here in my earlier answer to this.

Try Dexter library to check permission - WRITE_EXTERNAL_STORAGE

make sure that you have permission in AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

this is optional but library called Dexter easier handling instant permissions. add this dependency to build.gradle(app)

compile 'com.karumi:dexter:2.2.2'

Create application class:

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        Dexter.initialize(getApplicationContext());
    }

}

and set it in your AndroidManifest.xml

<application
       android:name=".MyApplication"

use this piece of code to ask user permission.

                Dexter.checkPermission(new PermissionListener() {
                @Override public void onPermissionGranted(PermissionGrantedResponse response) {

                    deleteFile();//call the method to delete file

                }
                @Override public void onPermissionDenied(PermissionDeniedResponse response) {
                    Toast.makeText(getApplicationContext(), "Permission denied", Toast.LENGTH_LONG).show();
                }
                @Override public void onPermissionRationaleShouldBeShown(PermissionRequest permission, PermissionToken token) {
                    token.continuePermissionRequest();
                }
            }, Manifest.permission.WRITE_EXTERNAL_STORAGE);
