如何在android studio中使用另一个SDK创建新SDK？

我正在使用另一个SDK创建新的SDK，当我试图成功构建SDK时，但当我在新应用程序中使用此SDK时，它会在运行时崩溃

下面是我的应用程序级别gradle，我提到了另一个SDK

apply plugin: 'com.android.library'

android {
compileSdkVersion 29
buildToolsVersion "29.0.2"
defaultConfig {
    minSdkVersion 18
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
    }
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard- 
     rules.pro'
       }
     }
 }

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
implementation project(path: ':aeps_lib-release')

implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.google.android.material:material:1.1.0'
implementation 'com.android.support:multidex:1.0.3'
}

在这里，我提到我的应用程序级grdale屏幕截图

屏幕截图中有我的新应用程序应用程序级别

当我试图在我自己的SDK的帮助下调用另一个SDK中的服务时，它会出错

这是我的日志错误

您正在为SDK使用.jar文件吗？@pawan soni我正在为SDK使用.aar filechange build gradle行-实现文件（'libs/“file_name”.aar'））
