Internal Error by start from IDE

Question

I develop a android app with visual studio 2012 and xamarin. I worke in a team with different machines. I start my android app on a nexus 4 device and everythink works. When I start my android app from a other machine, I get an internal error:

Deployment failed because of an internal error: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

Xamarin.AndroidTools.AndroidDeploymentException: InternalError ---> Mono.AndroidTools.InstallFailedException: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE] bei Mono.AndroidTools.Internal.AdbOutputParsing.CheckInstallSuccess(String output, String packageName) bei Mono.AndroidTools.AndroidDevice.<>c_DisplayClass2a.b_29(Task1 t) bei System.Threading.Tasks.ContinuationTaskFromResultTask1.InnerInvoke() bei System.Threading.Tasks.Task.Execute() --- Ende der internen Ausnahmestapelüberwachung --- bei Xamarin.AndroidTools.AndroidDeploySession.RunLogged(CancellationToken token) bei Xamarin.AndroidTools.AndroidDeploySession.Start(CancellationToken token)

I have deinstalled the app on my device, I deinstalled it with adb shell. Why I get this internal error. Any ideas? Have I to change my manifest?

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="net.package.name" android:installLocation="auto"  android:versionName="1.9" android:versionCode="10">
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="18" />
<application android:debuggable="true" android:label="name" android:icon="@drawable/ic_launcher" android:theme="@style/Theme.Styled"></application>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The problem related to ADB and not the code. As @ozwislon suggested you can have to uninstall manually the app when you want to install one from an other machine.

That's because of the android debug.keystore which is used to sign any debug application. To avoid that install/uninstall annoying issue in my team we are using the same debug.keystore which is located in C:\Users\your_username_here\.android

I don't find debug.keystore, i also try to avoid this annoying issue – StefanoM5 Dec 16 '14 at 08:41
It is usually located under user profile. Or this is your case http://stackoverflow.com/questions/16965058/where-the-debug-keystore-in-android-studio – madlymad Dec 16 '14 at 09:01
Thanx for answer, i'm using Xamarin, maybe in my case it should be in a file called adbkey or adbkey.pub ? – StefanoM5 Dec 16 '14 at 13:48
it must end in `.keystore` – madlymad Dec 16 '14 at 13:55
I don't find it in .android folder :( – StefanoM5 Dec 16 '14 at 14:15
Look in : C:\Users\{YOUR_WINDOWS_USERNAME}\AppData\Local\Xamarin\Mono for Android\debug.keystore – ComeIn Jul 06 '16 at 02:28

I had the same problem. All I had to do was go into the Settings | Applications menu and remove the application there first. For some reason the VS/Xamarin addon wasn't removing the app properly from the device. Even manually using the ADB shell didn't remove it properly for me.

If this doesn't work for you, there's a bunch of other things you can try here, on the Xamarin forums:
