อันนี้เป็น Code Build.gradle

apply plugin: 'com.android.application'
android {

minSdkVersion 19
targetSdkVersion 27
versionCode 1

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {

minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
useLibrary 'org.apache.http.legacy'
}
configurations {
all {
exclude module: 'httpclient'
exclude module: 'commons-logging'
}
}
dependencies {
compile 'org.apache.httpcomponents:httpclient:4.5.5'

androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
ผมก็แก้ตรงส่วนที่ชี้ไปยังไฟล์ PHP MySql แล้ว เป็นแบบนี้ String url = "http://localhost/android/saveADDData.php";
