Troubles with QtAndroidTools

[Dooham]

Hello everyone,

I want to implement the library QtAndroidTools of FalsinDoft because it has a lot of interesting features for Android.

I followed the instructions of the documentation but I received the errors like:

C:\Users\10alv\Documents\QtProgramas\PruebasAndroidTools\QtAndroidTools\QtAndroidTools.cpp:146: error: error: undefined reference to 'QAndroidAppPermissions::qmlInstance(QQmlEngine*, QJSEngine*)'

C:\Qt\5.12.2\android_x86\include\QtQml\qqml.h:629: error: error: undefined reference to 'QAndroidGoogleAccount::staticMetaObject'

C:\Qt\5.12.2\android_x86\include\QtCore\qmetatype.h:1476: error: error: undefined reference to 'QAndroidApkInfo::staticMetaObject'

C:\Qt\5.12.2\android_x86\include\QtQml\qqmlprivate.h:103: error: error: undefined reference to 'QAndroidNotification::~QAndroidNotification()'

C:\Qt\5.12.2\android_x86\include\QtCore\qmetatype.h:1832: error: error: undefined reference to 'QAndroidSharing::staticMetaObject'

For my first test, I tried to make an app that ask you for some permissions.

This is my .pro file:

QT += quick

CONFIG += c++11

# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Refer to the documentation for the
# deprecated API to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

include(QtAndroidTools/QtAndroidTools.pri)

SOURCES += \
        main.cpp

RESOURCES += qml.qrc

ANDROID_PACKAGE_SOURCE_DIR = $$PWD/android

DEFINES += \
    QTAT_APP_PERMISSIONS \
    QTAT_APK_EXPANSION_FILES \
    QTAT_APK_INFO \
    QTAT_SCREEN \
    QTAT_SYSTEM \
    QTAT_BATTERY_STATE \
    QTAT_SIGNAL_STRENGTH \
    QTAT_IMAGES \
    QTAT_NOTIFICATION \
    QTAT_ADMOB_BANNER \
    QTAT_ADMOB_INTERSTITIAL \
    QTAT_ADMOB_REWARDED_VIDEO \
    QTAT_PLAY_STORE \
    QTAT_GOOGLE_ACCOUNT \
    QTAT_GOOGLE_DRIVE \
    QTAT_SHARING

# Additional import path used to resolve QML modules in Qt Creator's code model
QML_IMPORT_PATH =

# Additional import path used to resolve QML modules just for Qt Quick Designer
QML_DESIGNER_IMPORT_PATH =

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

This my main():

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QtAndroidTools.h>

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);
    QtAndroidTools::InitializeQmlTools();

    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

And finally my main.qml:

import QtQuick 2.12
import QtQuick.Controls 2.5
import QtAndroidTools 1.0

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    color: "Red"
    readonly property var permissionsNameList: ["android.permission.WRITE_EXTERNAL_STORAGE","android.permission.READ_CALENDAR","android.permission.READ_PHONE_STATE","android.permission.READ_CONTACTS"]


    Button{
    x: 100
    y: 100
    width: 100
    height: 100
    onClicked: {
    QtAndroidAppPermissions.requestPermissions(permissionsNameList)
    }
    }
    Connections {
        target: QtAndroidAppPermissions
        onRequestPermissionsResults: {
            for(var i = 0; i < results.length; i++)
            {
                if(results[i].granted === true)
                {
                    setPermissionGranted(results[i].name, true);
                }
                else
                {
                    if(QtAndroidAppPermissions.shouldShowRequestPermissionInfo(results[i].name) === true)
                    {
                        if(results[i].name === permissionsNameList[0])
                            requestPermissionWRITE_EXTERNAL_STORAGE.open();
                        else if(results[i].name === permissionsNameList[1])
                            requestPermissionREAD_CALENDAR.open();
                        else if(results[i].name === permissionsNameList[2])
                            requestPermissionREAD_PHONE_STATE.open();
                        else if(results[i].name === permissionsNameList[3])
                            requestPermissionREAD_CONTACTS.open();
                    }
                    else
                    {
                        setPermissionGranted(results[i].name, false);
                    }
                }
            }
        }
    }
}

Does Anyones knows what I am doing wrong?

Thanks for your answers.

@Dooham said in Troubles with QtAndroidTools:

include(QtAndroidTools/QtAndroidTools.pri)

I think you have to move include(QtAndroidTools/QtAndroidTools.pri) after the defines!

[Dooham]

@KroMignon Ok that worked but now I get other errors:

@Dooham It look like there is an error in java class, the best is to contact the author. Maybe an Android API Level issue?
I don't know

[Dooham]

After doing some changes in the gradle file, I solved some errors but I get another one:

* What went wrong:
Execution failed for task ':transformResourcesWithMergeJavaResForDebug'.
> More than one file was found with OS independent path 'META-INF/DEPENDENCIES'

Does anyones know the solution?

@Dooham Ok I found the trouble. You have to add the following lines to the build.graddle:

 aaptOptions {
        noCompress 'rcc'
    }
	
	packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/ASL2.0'
    }

Almost every trouble that I had was related with this file, I let you the final build.gradle that I use and it seems works:

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.0'

    }
}

repositories {
    google()
    jcenter()
}

apply plugin: 'com.android.application'

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
    implementation 'com.android.support:support-v4:26.+'
        implementation 'com.google.android.gms:play-services-ads:16.+'
        implementation 'com.google.android.gms:play-services-auth:16.+'
        implementation 'com.google.http-client:google-http-client-gson:1.26.0'
        implementation('com.google.api-client:google-api-client-android:1.26.0') {
            exclude group: 'org.apache.httpcomponents'
        }
        implementation ('com.google.apis:google-api-services-drive:v3-rev173-1.25.0') {
            exclude group: 'org.apache.httpcomponents'
        }
}

android {
    /*******************************************************

       }
    }

    }

   }
