我想问一下，我能否在上周的模块安装方法中获得订单？我想接受最后一笔订单，并通过安装方法将其发送到我的installUrl（node.js服务器）。这是我的代码：

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'

    defaultConfig {
        applicationid "com.majaxtn.codingup"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'),'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs',include: ['*.jar'])

    implementation 'com.android.support:customtabs:28.0.0'
    implementation 'com.android.support:support-v4:28.0.0'

    implementation 'com.yarolegovich:discrete-scrollview:1.4.9'
    implementation 'com.google.firebase:firebase-core:17.4.3'
    implementation 'com.google.firebase:firebase-auth:19.3.1'
    implementation 'com.google.firebase:firebase-database:19.3.0'
    implementation 'com.firebaseui:firebase-ui-auth:4.1.0'


    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.13'


    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'androidx.recyclerview:recyclerview:1.2.0-alpha03'


    implementation 'androidx.appcompat:appcompat:1.1.0'




}
apply plugin: 'com.google.gms.google-services'

我需要在$ data数组中添加变量'orders'，该变量将包含最后命令的json。 无法找到任何信息
