It'll cover the previous install in this case. The package name is the unique identifier of the application in Android, we cannot install two applications with the same application id. This, of course, deletes internal storage and makes it impossible to test the migration code. It ALWAYS uninstalls the app before deploying. : emulator-5554 'run-as' '' 'cat' 'files/._tools_/version'Īny help would be greatly appreciated. : emulator-5554 pm install '/data/local/tmp/' : Looks like the package `` is already installed. : emulator-5554 pm install -d '/data/local/tmp/' Here's a snippet of the Xamarin Diagnostics output during deploy: : emulator-5554 setprop '' '' The target framework and API Level are different between the old app and the new one, but I'm hoping that's not the problem. In the simulator, I have backups turned off (that's the default, I think). In the project options, I have 'Use Fast Deployment (debug mode only) checked. In Tools > Options > Xamarin > Android Settings, I have 'Preserve application data cache on device between deploys' checked. The versionCode and versionName are both higher than the old version. The package name is the same in both versions of the app (package='' in the AndroidManifest.xml) How do I stop the uninstall and perform an 'upgrade' instead? Or, how do I preserve internal storage so I can grab the file I need to?

When I debug the new app (Xamarin.Forms) from Visual Studio, it ALWAYS uninstalls the app before deploying. To test this, I have a debug build of the old app (installed manually on the simulator via APK) running and the file is created. I need to grab a file from internal storage (/data/data//shared_prefs/titanium.xml) so I can migrate the settings stored in it over to the new Xamarin.Forms app. Currently, the app is written with Appcelerator (Titanium).
