如何从back4app.com连接到Qt Android应用程序解析服务器后端

Question

I am trying to develop an Android application with Qt 5.13 . I am planning to use a parse-server for my backend. I am using a free plan from back4app . I followed the official tutorial here

But I am not sure how to import the android SDK into my Qt C++ code. ?

I added the below code to the gradle.build file.

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar', '*.aar'])
    implementation "com.github.parse-community.Parse-SDK-Android:parse:1.20.0"
}

repositories{
  mavenCentral()
  jcenter()
  maven { url 'https://jitpack.io' }
}

After this step, I am not sure where to put below code

import com.parse.Parse;

I need to be able to run the below code in my C++ code.

Parse.initialize(new Parse.Configuration.Builder(this)
      .applicationId("appId")
      .clientKey("clientId")
      .server("https://parseapi.back4app.com")
      .build()

I tried to import in Qml code without luck.

Based on the documentation you need to put the code into a .java file. For that I'd suggest to check the guide on QAndroidJniObject Class , as you'll need to do your base implementation in java and using java native interface JNI to call the code from C++ .

Since you'll be needing https to access the server. You will also need to include openSSL libs to your project, you can find the required libs and instructions here
