Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.
QDir::mkpath: Empty or null file name
Invalid output directory:

Syntax: androiddeployqt --output <destination> [options]

Creates an Android package in the build directory <destination> and
builds it into an .apk file.

Optional arguments:
    --input <inputfile>: Reads <inputfile> for options generated by
       qmake. A default file name based on the current working
       directory will be used if nothing else is specified.

    --deployment <mechanism>: Supported deployment mechanisms:
       bundled (default): Includes Qt files in stand-alone package.
       unbundled: Assumes native libraries are present on the device
       and does not include them in the APK.

    --aab: Build an Android App Bundle.

    --no-build: Do not build the package, it is useful to just install
       a package previously built.

    --install: Installs apk to device/emulator. By default this step is
       not taken. If the application has previously been installed on
       the device, it will be uninstalled first.

    --reinstall: Installs apk to device/emulator. By default this step
       is not taken. If the application has previously been installed on
       the device, it will be overwritten, but its data will be left
       intact.

    --device [device ID]: Use specified device for deployment. Default
       is the device selected by default by adb.

    --android-platform <platform>: Builds against the given android
       platform. By default, the highest available version will be
       used.

    --release: Builds a package ready for release. By default, the
       package will be signed with a debug key.

    --sign <url/to/keystore> <alias>: Signs the package with the
       specified keystore, alias and store password.
       Optional arguments for use with signing:
         --storepass <password>: Keystore password.
         --storetype <type>: Keystore type.
         --keypass <password>: Password for private key (if different
           from keystore password.)
         --sigfile <file>: Name of .SF/.DSA file.
         --digestalg <name>: Name of digest algorithm. Default is
           "SHA-256".
         --sigalg <name>: Name of signature algorithm. Default is
           "SHA256withRSA".
         --tsa <url>: Location of the Time Stamping Authority.
         --tsacert <alias>: Public key certificate for TSA.
         --internalsf: Include the .SF file inside the signature block.
         --sectionsonly: Do not compute hash of entire manifest.
         --protected: Keystore has protected authentication path.
         --jarsigner: Deprecated, ignored.

       NOTE: To conceal the keystore information, the environment variables
         QT_ANDROID_KEYSTORE_PATH, and QT_ANDROID_KEYSTORE_ALIAS are used to
         set the values keysotore and alias respectively.
         Also the environment variables QT_ANDROID_KEYSTORE_STORE_PASS,
         and QT_ANDROID_KEYSTORE_KEY_PASS are used to set the store and key
         passwords respectively. This option needs only the --sign parameter.

    --jdk <path/to/jdk>: Used to find the jarsigner tool when used
       in combination with the --release argument. By default,
       an attempt is made to detect the tool using the JAVA_HOME and
       PATH environment variables, in that order.

    --qml-import-paths: Specify additional search paths for QML
       imports.

    --verbose: Prints out information during processing.

    --no-generated-assets-cache: Do not pregenerate the entry list for
       the assets file engine.

    --aux-mode: Operate in auxiliary mode. This will only copy the
       dependencies into the build directory and update the XML templates.
       The project will not be built or installed.

    --apk <path/where/to/copy/the/apk>: Path where to copy the built apk.

    --build-aar: Build an AAR package. This option skips --aab, --install,
       --reinstall, and --sign options if they are provided.

    --qml-importscanner-binary <path/to/qmlimportscanner>: Override the
       default qmlimportscanner binary path. By default the
       qmlimportscanner binary is located using the Qt directory
       specified in the input file.

    --depfile <path/to/depfile>: Output a dependency file.

    --builddir <path/to/build/directory>: build directory. Necessary when
       generating a depfile because ninja requires relative paths.

    --no-rcc-bundle-cleanup: skip cleaning rcc bundle directory after
       running androiddeployqt. This option simplifies debugging of
       the resource bundle content, but it should not be used when deploying
       a project, since it litters the "assets" directory.

    --copy-dependencies-only: resolve application dependencies and stop
       deploying process after all libraries and resources that the
       application depends on have been copied.

    --help: Displays this information.
