问题 I've downloaded the paypal-core-sdk for php from GitHub manually, my server does not have 'composer' and I've just manually copied the files to an include directory outside the document root. Problem is when I go call on some of the classes the server borks and doesn't know what I'm talking about ... i.e. Fatal error: Class 'PPApiContext' not found in /home/rctoronto/public_html/start.php on line 143 if I include once on the file providing PPApiContext, it moves along to another error and so

阅读更多关于 Android - Close app when home key is pressed

问题 I made this app that works fine, but when i leave the app and open it again it always force closes. how can i make it so when the user presses the home and or back key it will kill the app process? Making it so when the app is opened again it has a fresh start. 回答1: You are not supposed to "kill the process". You should handle home button presses and other such interactions that navigate away from your app via the onPause() and onResume() methods. In your onPause() method, you should save the

Catching NS_AVAILABLE_IOS while coding

阅读更多关于 Catching NS_AVAILABLE_IOS while coding

问题 I know how to change the lowest OS supported with IPHONEOS_DEPLOYMENT_TARGET . I am currently developing under Xcode 4.5 and using the iOS 6.0 SDK. What I'd like to do is find a way to throw a warning in compilation whenever I use code that is marked: NS_AVAILABLE_IOS(6_0) So that I can make sure that I don't miss any "Yes, but you're on iOS 5 so don't use this code" areas that will crash the user's device. 回答1: NS_AVAILABLE_IOS(6_0) is defined as __attribute((unavailable)) when the SDK is

微信小程序测试

阅读更多关于微信小程序测试

1、功能测试功能测试以原型为准，可以当成手机APP来测试 2、兼容性测试操作系统兼容性：Android系统和ios系统，如果有条件，可以尽量多测试主流Android系统品牌屏幕兼容性：小程序屏幕兼容性问题相对APP少一些，微信小程序定义了一个新的尺寸单位rpx(responsive pixel)可以适配不同尺寸的屏幕，在页面上定义对象的单位是rpx就可以在不同的屏幕上适配。但1rpx的像素经常在iphone7p上出现断线的情况。因此需要在测试过程中关注1rpx像素的显示。（测试时可忽略）微信兼容性：因为微信小程序SDK的API版本一直都在更新，导致SDK的API有可能有向下的兼容性问题并最终会影响到在最新版本小程序SDK上开发的程序不能在低版本的SDK 上像预期的那样运行。所以测试微信版本的兼容性之前要先确定小程序使用的库版本在哪些微信版本号上支持。 3、网络测试查看小程序在各种网络状况下的运行情况，比如：网络状况和环境的切换，断网，通过代理进行弱网测试 4、接口测试目前大部分都是微服务的架构，所以前端的小程序调用的是后台的接口，所以要对接口进行测试，这里的接口测试和平时的接口测试是一样的，没有特别之处。但是我们需要了解的就是，微信小程序SDK提供的接口是websocket，这是另外一种接口形式。 5、易用性跟APP测试一样 6、功能交互因为小程序是在微信里面
