我在android studio中創建了nexus 5和nexus 7模擬器。我一個接一個地啓動兩個模擬器。 Nexus 7仿真器工作正常，但在nexus 5中只包含黑屏，我等了1個多小時。問題是什麼。在android studio中創建了nexus 5模擬器，只顯示黑屏？
它顯示在消息：
emulator: device fd:628
HAX is not working and emulator runs in emulation mode
emulator: The memory needed by this AVD exceeds the max specified in your HAXM configuration.
emulator: AVD RAM size = 1536 MB
emulator: HAXM max RAM size = 512 MB
emulator: You might want to adjust your AVD RAM size and/or HAXM configuration to run in fast virt mode.
