Install build tools on arm64 doesn't work

I've been trying to install sdkmanager "build-tools;30.0.2" on an arm64 processor (ampere CPU).
But every time I get this:
Warning: Dependant package with key emulator not found!
Warning: Unable to compute a complete list of dependencies.
I'm trying to build an app and I get this error:
Failed to install the following SDK components:
build-tools;30.0.2 Android SDK Build-Tools 30.0.2
Edit: I think the problem is the package emulator isn't available. I tried downloading it from here but sdkmanager didn't recognize it.

(Assumption: CMD Line Tools are installed)
SDK manager package "emulator" is missing on ARM
Workaround:
Download emulator from Google for Linux: https://developer.android.com/studio/emulator_archive
Extract it to $ANDROID_SDK_HOME/emulator
You need a license file called "package.xml" which is automatically created when you download it via Android Studio UI SDK Manager, you copy that file to $ANDROID_SDK_HOME/emulator and change all version numbers related to the version you have downloaded:
... <revision><major>31</major><minor>1</minor><micro>4</micro></revision>...

I was able to install build-tools using sdkmanager on arm64 by copying to the sdk dir emulator from
https://chromium.googlesource.com/android_tools/+/refs/heads/main/sdk/emulator/
Unfortunately the installed packages seem to be not compiled for arm64 and are not working.

Anybody help to cross compile emulator for arm64 ?

Emulator for ARM64 hosts
Linux emulator source code now supports cross compilation from x86_64 to arm64 hosts, enabling running arm64 system images with KVM virtualization. Currently, only -gpu swiftshader_indirect (Swiftshader arm64 host rendering) is supported, but a compatible set of host GPU libEGL/libGLESv2 libraries may also be used by replacing lib64/gles_swiftshader with them and then relaunching with -gpu swiftshader_indirect. Snapshots may also not be working (add -no-snapshot to the command line).
Instructions:
cd emu
repo init -u https://android.googlesource.com/platform/manifest -b emu-master-dev --depth=1
repo sync -qcj 12
cd external/qemu
pip install absl-py
pip install urlfetch
sudo apt-get install crossbuild-essential-arm64
python android/build/python/cmake.py --noqtwebengine --noshowprefixforinfo --target linux_aarch64
Anybody try this one ?

Android Emulator not running for Cordova App - adb -s emulator-5584 shell cat /proc/cpuinfo

I'm trying to make my environment work with Cordova and Android emulator with no success. I have installed the Android Studio and I can successfully start the Android Emulator.
I have created a cordova application with the command below:
cordova create myApp
I added support for the Android platform:
cordova plataform add android
I had the following output:
Using cordova-fetch for cordova-android#~6.2.2
Adding android project...
Creating Cordova project for the Android platform:

Then I try to run the application:
cordova run android
The emulator starts, after a while, that I have the error below in the command prompt:

No emulator specified, defaulting to Nexus_5X_API_24
Waiting for emulator to start...
Error: Failed to execute shell command "getprop,dev.bootcomplete"" on device:

Does anyone knows how to fix this error?
Some others environment info:

Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
Edit 1
I have done those steps:
Uninstalled "Android SDK Tools"
Uninstalled "Android Studio"
Deleted files from "C:\Users\USER\AppData\Local\Android\sdk" and "C:\Program Files\Android\Android Studio" files (Because some maybe in use during the uninstallation)
Installed Android Studio
Updated Android Studio
When I execute the command below, I have more information about the error:
cordova run android --verbose
With this output:
Command finished with error code 3221226356:
C:\Users\USER\AppData\Local\Android\sdk\platform-tools\adb.exe
-s,emulator-5584,shell,cat,/proc/cpuinfo Error: Failed to execute shell command "cat,/proc/cpuinfo"" on device: Error:
C:\Users\USER\AppData\Local\Android\sdk\platform-tools\adb.exe:Command
failed with exit code 3221226356
When I execute the command below, the adb shows the emulator cpu info, after that, the process stops and the windows ask to break or debug
adb -s emulator-5584 shell cat /proc/cpuinfo

Downgrade your SDK platform-tools to rev25.0.1.
If you dev in windows, you can download it in https://dl-ssl.google.com/android/repository/platform-tools_r25.0.1-windows.zip
delete or rename your old platform-tools folder, and extract the downloaded file to it.
Works for me!

I encountered the same issue with an emulator of Nexus5 & Oreo/Nougat.
I changed my emulator to Galaxy Nexus & Lollipop and it worked fine without any modification in the Cordova directories.
It does not seem to be the right solution, but some lower combinations might be available for avoiding this issue.
The command line is:
$ cordova emulate android
The following is the success log:
No emulator specified, defaulting to Galaxy_Nexus_API_22
Waiting for emulator to start...
emulator: Requested console port 5584: Inferring adb port 5585.
emulator: WARNING: encryption is off
path /home/ximia/.android/avd/Galaxy_Nexus_API_22.avd/system.img.qcow2
Waiting for emulator to boot (this may take a while)...BOOT COMPLETE

Edit your virtual device (ADV) and go into advanced settings and uncheck Multi-Core CPU.
Work fine to me.

Unable to compile on QT for Android

I am new to QT programming and am trying to build a simple program on Android. I have installed QT 5.8, latest Android SDK, NDK and apache ant, but it gives the same error. I searched about this issue and tried using older versions of QT(5.5.1 and 5.7.0) , Android SDK as well as NDK, but its not helping. I tried giving the build path a shorter name, removed all the folders which had spaces in the title and reinstalled everything. Please help.

Qt 5.2 and Android Error

So after a few hours of struggling to set up my Qt so I can start with my first Android app I am still without luck.
I’ve gotten a VERY simple program (just to get all the settings right) to build properly but when I click the play button to run it, there is an error I cannot seem to solve. Here is the complete output when I press play:
22:16:45: Running steps for project Androidtest...

I read that sh.exe might be in the path variable but I don’t think its there, here is the value for path:

C:\Android\AndroidSDK\sdk\platform-tools;C:\Program Files\Java\jdk1.7.0_51\bin;
C:\Qt\Qt5.1.1\5.1.1\mingw48_32\bin;
I am using win7 32bit, Qt5.2 and Qt Creator 3.0.1.

I found that I had more than 1 version of Qt installed. So I uninstalled Qt completely and only installed the latest version. That solved all my problems.
