Many of these version upgrades required rewriting portions of native Android applications to continue to operate. Now you may need specific code that will only work with specific versions of Android. TPI can offer a couple different alternatives that will allow for a smooth transition to Android, preserve your code base to operate under multiple operating system upgrades and different devices.
Do yourself a favor. Call us now! NET Compact Framework". This could give you a better idea of how much you might have to change. The APIs are significantly different in Windows CE, some aspects may port easily but it will likely need a fair amount of modification.
It is possible, but you will have to limit yourself to what is available in the. Net compact framework. So be sure you close your database connections neatly use a finally clause! By the time you have revised code running on your device you will find it very hard to port back, so look to keep a new tree on your source control entirely How are we doing?

In addition to the development and deployment tools installed on your machine you will also need the following to enable retail signing:. If you have one or more custom applications that you want to include in your Windows 10 IoT Core retail image, you need to verify that these applications are signed properly when including them in your retail image. To add a new application to an existing OS Design you can either add the project as a sub-project to the OS Design Project or you can create normal deployment CAB packages to deploy those to the device as part of the initial device setup.
Since a package is the smallest unit of updating, make sure that each package is as small as possible. For custom assets added through the IoT ADK packaging commands: Make sure the packages created are as small as possible. In general, the recommendation is not to modify the resulting package produced by Platform Builder to include additional components into the system image. Instead, follow the Windows 10 IoT Core manufacturing guide.
However, if files must be added to the package that is created by Platform Builder, follow your existing process. When adding content to the package generated by PB, consider the following:. There is a maximum size for packages about MB and exceeding this size will prevent updating. Updates happen on package granularity.
If a single asset in the package needs to be updated, then all the assets of that package will be updated at the same time. To reduce the size of updates, isolate content into separate packages to minimize the overall update size. The packaging process detailed above is driven by the same inputs that go into building a CE BIN file.
So, if the files are referenced in OSDesign. XML files for each memory section. This is done so that updates can be pushed in a more granular fashion as the minimum unit of update is a package. The recommended approach to communicate between applications running in the CE Container is to use Local Loopback. You can read more on Local Loopback in this document.
However, some legacy applications may rely on this behavior to run correctly. Create the following registry key:. Host Serial ports need to be mapped into the CE environment.
