I can't run the Android Emulator

问题

I'm completely new to Android and Android Studio. I was just coding. So I was running the previous version of Android Emulator and it worked perfectly fine.

1. However, when I downloaded the latest Android Emulator 27.1.12, my Emulator couldn't run properly.
   Issue: The code is running fine, but the Emulator can't display my application. When I click on the Emulator screen, I can still hear the Audio of my app. So I think the problem would be with my computer's hardware.

2. Because the Emulator couldn't run, I uninstalled the Android Emulator 27.1.12 and Android Studio reported these errors:
   Issue:

   08:32 Emulator: [6684]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at C:\Users\dell\AppData\Local\Android\Sdk\emulator\lib64\qt\lib
   
   08:32 Emulator: Could not launch ‘C:\Users\dell\AppData\Local\Android\Sdk\emulator/qemu/windows-x86_64/qemu-system-i386.exe’: No such file or directory.

So, when I install the Emulator, it crashes, when I un-install it, I encounter these 2 errors. So is there a way for me to use the Emulator without causing the 2 errors?

回答1:

I am not sure from your question, whether or not you have uninstalled and reinstalled the AVD Manager, so in the case you haven't:

I suggest you completely uninstall and then reinstall the Android Virtual Devices SDK (AVD Manager).

You can use the following instructions to help you out:

To uninstall/install the AVD Manager, go to Tools > SDK Manager > Android SDK and select the SDK Tools Tab. Then scroll down until you find the Android AVD/Virtual Devices SDK.

Also, make sure that the Android Emulator SDK is also installed.

I see in the new update of Android Studio, the Android Emulator option is not enabled by default. So, let enable it in the Settings as the bellow and run Android Emulator again.

回答3:

Have Android 3.2.1 which you need to install emulator manually by going into Tools > SDK Manager > Android SDK and then select the SDK Tools Tab. Check the 'Android Emulator' then Apply.
