Multi-instance

Emulator multi-instance settings with emulator type and instance index

When multi-instance mode is enabled, emulator type, instance index, and ADB port must match. Supported types include MuMu, MuMu Global, LDPlayer, BlueStacks, BlueStacks Global, Nox, MEmu NAT, and Windows Subsystem for Android.

ADB Port Reference

When automatic scanning cannot find the device, fill the ADB port manually. Common legacy backend defaults:

EmulatorDefault Port
MuMu 12 5.0+5555
MuMu 1216384
Older MuMu7555
LDPlayer5555
BlueStacks5555
MEmu21503
Nox62001 or 59865

Multi-instance ports usually increase by instance number:

EmulatorPort Formula
MuMu 12 5.0+5555 + instance number * 2
MuMu 1216384 + instance number * 32
Finding the ADB debug port in MuMu 12 multi-instance manager

BlueStacks, LDPlayer, and similar emulators may require enabling ADB debugging in emulator settings. Debug with one instance first, then configure multi-instance.
