Why make user login in android SDK of PayuMoney gateway?

阅读更多关于 Why make user login in android SDK of PayuMoney gateway?

问题 I am trying to integrate PayUMoney SDK for android and successfully added the SDK in my application. When the user clicks on the pay button a login page opens up. Why should the user be made to login/create an account for payu? As soon as the user presses the pay button the options for payment should open up but that is not the case. I have tried the sample app given by them in github too and seems that it has the same flow. I got a video in youtube showing the problem for anybody who would

阅读更多关于 How to include an external jar file to aar file in Android

问题 I want to develop a solution that allows me to use an external jar library in an SDK generated in aar file for an Android project. What I have as inputs : SDK : "de.xx.sdk:xxx-android-v1.0.0" external library : "libs/xxxx-v1.0.0" what I found out in my investigation is how to exclude a library from project like the following : implementation('android.arch.work:work-runtime:1.0.0') { exclude group: 'com.google.guava', module: 'listenablefuture' } Is there something similar to write in gradle

When should I use the addSubview method of a view controller?

阅读更多关于 When should I use the addSubview method of a view controller?

问题 I'm programming for the iPhone and I'm wondering when to use the addSubview method of a view and when to present to use the modal view controller (presentModalViewController). What complicates this even more is if you are using a navigation controller (I'm not) and you can use the pushViewController method? When would you use each and why? Thanks. 回答1: -presentModalViewController and -pushViewController are two ways of going about the same thing: displaying a new view. Which you use depends

How to configure Android Emulator once SDK is installed

阅读更多关于 How to configure Android Emulator once SDK is installed

问题 I am trying to get the Android emulator up and running on my 64-bit Ubuntu 12.04 distro. First, I had to install ia32-libs to get around some earlier issues that I had encountered on previous (failed) attempts. I then downloaded and installed the 64-bit linux distro. I navigated to the android application (SDK Manager) on the command line, and ran it. I downloaded Android Tools and the latest flavor of the Android OS. I would now like to run emulator , but when I do, I get the following error

Kinect for Windows SDK v1.0 Beta 2

阅读更多关于 Kinect for Windows SDK v1.0 Beta 2

Kinect for Windows SDK v1.0 Beta 2 久々にKinect SDKネタです。ご存知の方も多いと思いますが、 http://www.kinectforwindows.org から、SDKのVersion 1.0 Beta 2が公開されています。その前のバージョン向けに書いたプログラム、ほぼそのままコンパイルが出来るようですが、幾つかポイントを紹介しておきます。先ず、SDKを新しくインストールして、プロジェクトをVisual Studioで開くと、Kinect関連ライブラリを提供するコンポーネントの場所が変わっているので、参照設定を更新します。新しい、SDKのコンポーネントは、 c：￥Program Files￥Microsoft SDKs￥Kinect￥v1.0 Bata2￥Assemblies に格納されているので、Microsoft.Research.Kinect.dllをそっちに変更してください。それから、新しいバージョンのSDKは、Kinectセンサー複数台接続対応がより充実した関係で、Runtimeクラスのインスタンス生成方法も変わっています。従来1台のセンサーのみの場合であれば、 var runtime = new Runtime(); だったものが、古くなり、 var runtime = Runtime.Kinects[0];

Android开发环境搭建可以分：第一步、安装JDK；第二步、安装Eclipse；第三步、下载并安装AndroidSDK；下面详细介绍。第一步、安装JDK Android开发工具要求必须安装JDK(JavaDevelopment Kit)，不能只安装JRE(Java Runtime Edition)，在安装Android开发工具之前需要先安装JavaJDK。尤其是Eclipse的开发过程必须要JDK或者JRE的支持，否则在启动Eclipse的时候就会报错：首先，去JAVA官网上（http://www.oracle.com/technetwork/java/javase/downloads/index.html）下载JDK（注意是下载JDK，不是JRE），点击JDK下载按钮后，进入JDK版本选择界面，找到适合自己电脑系统的JDK版本，并下载，如下图所示，win32位的系统选择Windows x86,64位的系统则选择Windows x64安装：下载好后，双击安装：然后选择好自己要安装的路径：安装JDK的时候，会自动给你安装JRE，选择好自己要安装的路径就行了：然后就不断下一步，到最后安装完成：安装好后，要配置环境变量。新建一个系统环境变量，变量名为JAVA_HOME，变量值为JDK的安装路径，如下图所示：然后在系统变量列表中，双击Path变量，并将;
