The Android project doesnt deploy from Visual studio to Samsung Tab. Initially the output shows deploying to device, after 2 minutes, it changes to Ready state and doesnt deploy even after 30 mins.

Below is the part of output I get repeatedly[couldnt attach whole output]. Can anyone help me why this happens? Thanks in Advance

Solution

The issue was resolved by unchecking Enable Startup Tracing inside the Android option, which sets AndroidEnableProfiledAot to false.
