How to check android device supports Trusty TEE or not? - android

I want to implement TEE, can someone please guide me how to start it. And also I want to check which device supports TEE.
I am working on a mobile wallet app in Android, I'm new to this field (TEE), and I have searched a lot about how to implement Trusty TEE but did not find any tutorial.
How do I enable it? Any links or tutorials?
If not Google Trusty TEE, what else can I use?
I am not getting any proper answers. Thanks in advance!

Account manager integration - Android vs iOS

I am Android developer, but I need to answer to some questions regarding what is possible with other platforms and I wonder what iOS offers that is comparable to http://developer.android.com/reference/android/accounts/AccountManager.html. I found https://developer.apple.com/library/ios/documentation/Accounts/Reference/ACAccountClassRef/Reference/Reference.html but I can not understand the full range off possibilities.
Questions:
How Account Manager used in iOS??
In Android it is possible to share tokens for a service, does iOS have the same feature
Is there a centralized API or is this solved app-2-app?
Are there any security concepts available connected to this (restrict access to tokens to certain apps and so on)
Happy for short and quick responses!

There is not AccountManager type feature available in iOS. Yo need to add and implement Setting.bundle for your preferences as similar account manager will do in Android.
Please check this links:

Apple Doc for Setting.bundle

Android - WiFi API for Android 2.2 or 2.3

I have to make a peer to peer file sharing app on android platform
Can someone tell me about the WiFi API that i can use for it and how can i get these API's
Thanks in advance.
This question is too broad for SO. This platform is meant for specific programming questions (i.e. you've already done the research, and tried something but are having trouble. Post your troubles and we'll try to help)
search around on the developer site some. Here is a page that might be of interest to you to get started: http://developer.android.com/guide/topics/wireless/wifip2p.html

Is it possible to accept payment in all currency in my android app using google checkout?

I am trying to integrate payment gateway in my android app.
Purpose of app is to buy online e books.
Site is already Developed and it is using EBS service for payment.
To be specific App is designed for Asian countries only.
Can anyone help me regarding this?
Do i need to simply call my site URL for this or it is not a practical approach.
Any help would make work my simpler as i am not familiar with this stuff.
Please help me if you have experience with it but please do not just copy paste links as i have gone through many sites for that.
Here, EBS support you can find the API that EBS provides. There is no specific API currently available for android. I think you should have to implement it at your server side and make a call with web services.

how do i find proximity support in Qualcomm's AllJoyn sdk for Android

I am trying to get a clear idea about Proximity mention in AllJoyn app and there are several explination (theories) that i find intresting but , I still want to know can Alljoyn support proximity? If yes then how do I go about it? Can I see an example using proximity or reference a sample App as im not able to find proper references to the same. The Chat app I've seen works perfectly using WiFi but how can i accomplish the same using a bluetooth? Kindly help me..Thank You in advance..
Bluetooth support is only available in the android sdk. In order use bluetooth, you either have to wait until AllJoyn is adopted by OEMs, or rooting your phone and doing some fiddling. More info can be found https://www.alljoyn.org/docs-and-downloads/documentation/alljoyn-android-environment-setup-guide#unique_21
If/when bluetooth is integrated/supported, your use of AllJoyn should be the same, as AllJoyn works to hide the communication details from you.

Skiller Android SDK: Adding a buddy while playing a game?

Hoping to find some Skiller experts to answer this. I've been using Skiller for developing my game for last 3 weeks. The Skiller documentation does not explain how a player can add a buddy while playing a game? Is that possible? If that's the case, is that documented anywhere?
From the SDK documentation, I can see that BUDDY_LIST is an optional argument to call the showScreen() method but I don't know whether it work during game play? Any guidance would be much appreciated.
I am VP R&D at Skiller, thanks for using our SDK.
To shorten the integration time and at the same time give the developers many additional elements to their game and make it more appealing, many things were implemented for the developers. You don't need to implement all the community features from the scratch. We do it for you and expose many tools to communicate and manage the community.
In current and previous Skiller SDK versions all you need to do is raise the buddy list window and the window in its turn already implements all the functionality of adding/removing/searching for buddies.
In the next version of the SDK we will expose the API using which you will be able to add the last opponent that your user played against as a buddy.
If you have any other questions I can help you with please send email to developers#skiller-games.com or visit our developers forum on www.skiller-games.com
