Move the zip to this folder and unzip it
Rename the folder
mv tools old-tools
Install missing dependencies & the famous tools:
sudo ./sdkmanager --sdk_root=/home/<USERNAME>/.buildozer/android/platform/android-sdk/ --install "tools"
sudo ./sdkmanager --sdk_root=/home/<USERNAME>/.buildozer/android/platform/android-sdk/ --install "build-tools;29.0.0-rc3"
sudo ./sdkmanager --sdk_root=/home/<USERNAME>/.buildozer/android/platform/android-sdk/ --install "platforms;android-27"
sudo ./sdkmanager --sdk_root=/home/<USERNAME>/.buildozer/android/platform/android-sdk/ --install "platform-tools"
sudo ./sdkmanager --sdk_root=/home/<USERNAME>/.buildozer/android/platform/android-sdk/ --install "patcher;v4"
