You can add these directives to your Android project, when you use EMDK (all EMDK code is under Android project!). Now your projects have the right configuration to use preprocessor directives. In вЂњProject OptionвЂќ popup, select вЂњCompilerвЂќ and add вЂњNO_EMDKвЂќ symbol.Дouble click to Android Solution and add NO_EMDK symbol. Select вЂњReleaseNoEMDKвЂќ and double click PCL Solution. Now, when you try to change your configuration, you should have a situation like this: Obviously, you can do the same with вЂњDebugвЂќ configuration if you need to debug your app without EMDK installed. Select вЂњReleaseвЂќ configuration, press вЂњCopyвЂќ and create a new вЂњReleaseNoEMDKвЂќ configuration. Add a new configuration.Дouble click to вЂњ(master)вЂќ solution and select вЂњConfigurationsвЂќ, you should see something like this (I hope MFractor developer do not be angry for popupвЂ¦ )):

I have VS4Mac in ItalianвЂ¦ maybe a little different from English version. I add some pictures to explain better all the steps. To use these directives we have to create a new configuration for our solution. Preprocessor directive are very powerful. Yes, my code needs EMDK! How can I solve this problem? Remove EMDK code with preprocessor directives All seems to work fine andвЂ¦ДЄnother big problem. Now I try to deploy again the app to my AVD. The default value for android:requiredВ if not declared is 'true'.

When you declare android:required='false'В for a feature, it means that the application prefers to use the featureВ if present on the device, but that it is designed to function without the specified feature, if necessary.

When you declare android:required='true'В for a feature, you are specifying that the application cannot function, or is not designed to function, when the specified feature is not present on the device.

What does it mean? Here all explanations you need.Д«oolean value that indicates whether the application requires the feature specified in android:name. I have to modify AndoridManifest.xml and add the code in вЂњ boldвЂњ How can I solve this problem? Modify AndroidManifest.xml It seems that I should have a device with EMDK installed to deploy my app. Library/Frameworks/amework/External/xbuild/Xamarin/Android/.targets(516,2): error : Failure

I start a debug session and APK is deployed to AVD andвЂ¦ now start problems! So, I open вЂњAVD ManagerвЂќ in Visual Studio for MACВ and run Android Accelerated x86 AVD. For example, I would like to test it with an Android Virtual Device. Now I would like to use my app without a TC51 device. You can find a lot of information and code samples here. I use EMDK to work with integrated barcode reader. TC51 is a very interesting rugged device. I have a Xamarin Forms app that is deployed to a Zebra TC51 device.
