.NET for Android error ADB0040

Mensagens de exemplo

error ADB0040: The device does not support the minimum SDK level specified in the manifest.

Questão

ADB0040 means that you are trying to deploy to an emulator or device that has an older Android version than what your .NET for Android application supports.

This message indicates that adb (Android Debug Bridge) reported an INSTALL_FAILED_OLDER_SDK error. adb faz parte do SDK do Android e é usado internamente pelo .NET para Android para se comunicar com emuladores e dispositivos Android. Saiba mais sobre adb na documentação do Android.

Solução

Verify you are setting the appropriate values for uses-sdk in your AndroidManifest.xml:

<uses-sdk android:minSdkVersion="15" android:targetSdkVersion="27"/>

Your attached device must at least be able to support minSdkVersion.

Notas de implementação

Note that nothing in the open source https://github.com/xamarin/xamarin-android repository emits ADB0040, as features such as debugging and "fast deployment" are implemented in the proprietary .NET for Android additions.
