Android Studio Project require older version of Gradle

I'm trying to compile some Android Studio Project, but get this error message:

Gradle sync failed: Gradle version 2.2 is required. Current version is 3.3.

When I click to fix issue link near the message, I'm getting:

Gradle sync failed: Could not find property 'androidCompileSdkVersion' on com.android.build.gradle.AppExtension_Decorated@580ec9dd.

In file 'android-build' I have:

/*******************************************************
 * The following variables:
 * - androidBuildToolsVersion,
 * - androidCompileSdkVersion
 * - qt5AndroidDir - holds the path to qt android files
 *                   needed to build any Qt application
 *                   on Android.
 *
 * are defined in gradle.properties file. This file is
 * updated by QtCreator and androiddeployqt tools.
 * Changing them manually might break the compilation!
 *******************************************************/

compileSdkVersion androidCompileSdkVersion.toInteger()

buildToolsVersion androidBuildToolsVersion

sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = [qt5AndroidDir + '/src', 'src', 'java']
        aidl.srcDirs = [qt5AndroidDir + '/src', 'src', 'aidl']
        res.srcDirs = [qt5AndroidDir + '/res', 'res']
        resources.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        assets.srcDirs = ['assets']
        jniLibs.srcDirs = ['libs']
   }
}

In my case with Qt 5.11.1, the easiest fix was to just copy the gradle.properties file from the android build directory to sit next to build.gradle.

I found it here:

build-MyApp-Android_for_armeabi_v7a_GCC_4_9_Qt_5_11_1_for_Android_armv7-Release/android-build/gradle.properties

Once copied in, Android Studio was able to sync. Make sure not to commit this file! You'll need to copy another one if you upgrade Qt.

Change the gradle version at your project root build.gradle file like below

classpath 'com.android.tools.build:gradle:2.3.3'

Or change it to the latest gradle version which you have upgraded to.
