Android DownloadManager class not working mobile 4G data?

I have developed an android application using Android DownloadManager Class. When I try to download file over WiFi working without issue but when I use mobile data downloading not working, showing waiting for network.
This is my code:
DownloadManager.Request request = new DownloadManager.Request(Uri.parse((urlString)));
manifest.xml permissions:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
and this is my reference page: Android DownloadManager example

From what you've provided I can only recommend you to remove the unnecessary code s.a. request.setAllowedNetworkTypes(Request.NETWORK_WIFI | Request.NETWORK_MOBILE); because it by default allows all types of network. Also make sure you haven't set setAllowedOverMetered() and setAllowedOverRoaming() to false.

Oracle MAF and requesting permissions in Android 6.0 (API level 23)

I have an MAF application that uses the devices camera to take a picture. Everything was working fine until I tested it on an S6 running API 23, where it crashed with:
java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=3432, uid=10060 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()
As far as I can tell this is because of the way Android are handling permission in the newer API's, noted here:
https://developer.android.com/training/permissions/requesting.html
Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app.
So I followed the instructions on how to request permission during run-time (I've installed Android Support Libraries), the problem is, the method signature looks like this:
int checkSelfPermission (Context context,
String permission)
I cannot find a way to get a reference to the context (the example in the provided link also uses an Activity, same problem there). I just don't have the faintest clue how to do this from within MAF, as it seems Application/Activity objects are not exposed.
I have tried simply extending Activity in one of my classes and attempted to call the checkSelfPermission method with this but then I get run-time errors, after reading up on what an Activity is I understand why this is wrong.
tl:dr
How do we handle the new Android 6 (API level 23) run-time permission requests with oracle's mobile application framework?
Edit:
So as per the discussion in the comments we can see the app is supposed to still function normally on Android 6, even if you're not requesting permissions at run-time.
So I had a look at the AndroidManifest.xml file that MAF is generating on build, and I can see that the permission (from the above exception) android.permission.READ_EXTERNAL_STORAGE is not present:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE"/>
<permission android:name="com.bsaf.atlas.permission.C2D_MESSAGE" android:protectionLevel="signature"/>
<uses-permission android:name="com.bsaf.atlas.permission.C2D_MESSAGE"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.INTERNET"/>
Also interesting, is that the GPS location does not update either, and the log is constantly posting this:
07-07 02:07:13.089 2174 2174 E LocationProvider: Caught security exception registering for location updates from system. This should only happen in DumpRenderTree.
So my next question is, how do I influence AndroidManifest.xml within MAF? And why is this struggling with location updates?

UPDATE (22/08.2016):
This was actually happening because I was setting the target SDK to 23 in my build configurations. Downloading the new Eclipse simply reset this back to the default (21)
Old Answer:
I solved this by downloading OEPE for Neon (I was using OEPE for Mars).
Oracle Enterprise Pack for Eclipse
The application now correctly generates a popup requesting permission to use the camera.
Please note, this has created an issue with location services and the app crashes when requesting gps location, I have not yet discovered a fix or the source of the problem.

I really have no idea why it only occurs on a few devices; my initial guess is it has something to do with Samsung KNOX, and the (few) users that are crashing are KNOX users with a phone policy to disable Bluetooth.
Has anyone else run into this? Or does anyone have any idea what this might be?

If you are sure the users met this problems only on Samsung KNOX,the following answer maybe will help you.
Thinking step by step is the way to solve your problem.
1.This only occurs on some Samsung devices.
So, it has nothing to do with your code,also the permission.There is
something wrong with the Samsung devices.
2.Check the crash log:
java.lang.SecurityException: Need BLUETOOTH permission: Neither user 10025 nor current process has android.permission.BLUETOOTH.
According to the experience,if you have met the log like "Neither user
**** nor current process has *** permission.",this means that your app doesn't have the permission to do something in the system.This occurs
often on that you do something need the system level permission.
If you are installed as system level app together with customized Android ROM,or you signed your app with the platform.x509.pem and platform.pk8 file of the customized Android ROM,and then you can have the permission.
Now check what is Samsung KNOX:
Samsung Knox (stylized Samsung KNOX) is an enterprise mobile security solution.
Bluetooth is one kind of data transmission way to the other's
device.This will cause the security problem.
Check the offical website:
https://www.samsungknox.com
Search the key words 'Bluetooth',and we found this:
https://www.samsungknox.com/en/faq/are-bluetooth-bluetooth-low-energy-and-nfc-available-inside-knox-container
KNOX 2.4+ — Bluetooth, Bluetooth Low Energy (GATT), and NFC are supported inside the KNOX container.
KNOX 2.3 or below — Bluetooth, Bluetooth GATT, and NFC aren't supported inside the KNOX container. If the device is connected to a peripheral (e.g. headphones) in the personal space, Bluetooth will remain connected, even if the user enters the KNOX container. Apps inside the KNOX container can't initiate a Bluetooth connection.
1.If your users are using KNOX 2.3 or below,and they can update their OS of device to KNOX 2.4+.tell your users who use Samsung
KNOX update their OS of device.
2.If your users are using KNOX 2.3 or below,and they can't update their OS of device to KNOX 2.4+.your app will not work under this
situation,the problem is not the problem,what you can do is only tell
uses that:the OS of your device doesn't support Bluetooth,so it's not
working.
3.If the above will not help you, you can contact with Samsung KNOX Official
Another tip:
To improve your user experience of your app, you need to prevent your app to be crashed.
Crashed is the worst user experience.
If you can not solve the problem,you can do this:
try{
You code related with Bluetooth.
}catch (Exception e)
{
}
Remember:The offical always helps you to solve the problems better!

You can look here. I'd guess this is your problem.
Are Bluetooth, Bluetooth Low Energy, and NFC available inside the KNOX container?
KNOX 2.4+ — Bluetooth, Bluetooth Low Energy (GATT), and NFC are supported inside the KNOX container.
KNOX 2.3 or below — Bluetooth, Bluetooth GATT, and NFC aren't supported inside the KNOX container. If the device is connected to a peripheral (e.g. headphones) in the personal space, Bluetooth will remain connected, even if the user enters the KNOX container. Apps inside the KNOX container can't initiate a Bluetooth connection.
I never had any hands-on experience with this, but I hope this helps.

try to add below to your manifest
<uses-feature android:name="android.hardware.bluetooth" android:required="true" />

From SDK 23 onward you need to check the permission for bluetooth in case required.
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (mContext.checkSelfPermission(Manifest.permission.BLUETOOTH) == PackageManager.PERMISSION_GRANTED) {
//TODO - Do the work
}
}

From KNOX Premium v1.1 onwards, Samsung no longer needs to sign third-party app (APK) files so that they can run inside KNOX containers. Instead, the appropriate permissions are granted at runtime, after an app activates its ELM and KLM licenses successfully. for more info see this

Android wifi p2p unsupported (wifidirect)

i'm using the protocol for making p2p connection using wifi in android (http://developer.android.com/reference/android/net/wifi/p2p/package-summary.html)
I have a problem calling the discoverPeers() function :
ActionListener.onFailure(int reason) is called (its an interface to trigger some events) and i receive reason=1, which means 'P2P_UNSUPPORTED'.
I added all the permissions required and the (use... wifidirect) tag.
i'm using a virtual device and the latest android sdk(4.0.3),
i have an internet connection on this device.
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses permission android:name="android.permission.INTERNET"/>
<uses-feature android:name="android.hardware.wifi.direct" android:required="true"/>

As far as I know you can't run the demo in the emulator because it doesn't support real Wifi.
You should launch the demo on a real device like the Galaxy Nexus which supports ICS and Wifi-Direct.

facepalm Yea...I was running on an emulator instead of the real deal...works fine if you use a device that ACTUALLY has Wifi...ha!

Android: Can't add new In-App products to application...?

I am making a game with in-app purchasing for extra levels. I have implemented all of the necessary code and the test purchases work perfectly. However when I go to add the products to my (unpublished) app I get the following message on the android developer dashboard:
"New in-app products cannot be added because the current application version does not use the BILLING permission."
These are the permissions I have:
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.com.android.vending.BILLING" />
<uses-permission android:name="android.permission.BILLING" />
So I can't understand why I am getting this message. Any help would be greatly appreciated, I am trying to release the game this weekend and this is my last barrier.
Thanks in advance, and rest assured I WILL accept an answer, I know people on here get worried about that sometimes.

The problem is with the permission. Use
<uses-permission android:name="com.android.vending.BILLING" />
It looks like your app gets all the permissions it needs. My advice is to make sure that the uploaded version of the app is the current version, and also that you are logged in using your Google Checkout Merchant account (this is different from a regular Google or Google Checkout account) as referenced By the docs. Hope this helps!
