Android test project is crashing with error “Test run failed: Instrumentation run failed due to 'Process crashed.'”

Question

Answer 1

In my case it was a StrictMode policy violation caused by AndroidJUnitRunner:

D/StrictMode: StrictMode policy violation: android.os.strictmode.UntaggedSocketViolation: [...]
W/System.err: StrictMode VmPolicy violation with POLICY_DEATH; shutting down.

Disabling the check detectUntaggedSockets() when running an Espresso test fixed it for me. See this question for how to check for that.
