The Service’s selector matches no ready pods, so traffic to it is refused or returns 503.

The device or emulator doesn’t have enough free internal storage to install the APK.

INSTALL_FAILED_TEST_ONLYAndroid

INSTALL_FAILED_TEST_ONLY: installPackageLI

The APK is marked testOnly (built by Android Studio’s Run button), so normal installs refuse it.

The scheduler can’t find a node that satisfies the pod’s resource requests, selectors, taints or volume constraints.

EvictedKubernetes

Kubernetes: Pod Evicted — The node was low on resource: memory / ephemeral-storage

The kubelet removed the pod because its node ran short of memory or disk.

INSTALL_FAILED_USER_RESTRICTEDAndroid
