From the first code, you getting "Directory is not created" is because the directory is not created.
Modify your code to this way
File dir = new File(Environment.getExternalStorageDirectory() + "/AutoBuddy/");             Log.i("dir is ", "" + dir);             dir.mkdir();   // create directory             try {                 if (dir.mkdir()) {                     System.out.println("Directory created");                 } else {                     System.out.println("Directory is not created");                 }             } catch (Exception e) {                 e.printStackTrace();                 Log.i("Creating Dir Error", "" + e);             }

Is ok, thanks !

Here an example for pass by value
public class Swap { public static void main(String args[]) { Animal a1 = new Animal("Lion"); Animal a2 = new Animal("Crocodile"); System.out.println("Before Swap:- a1:" + a1 + "; a2:" + a2); swap(a1, a2); System.out.println("After Swap:- a1:" + a1 + "; a2:" + a2); } public static void swap(Animal animal1, Animal animal2) { Animal temp = new Animal(""); temp = animal1; animal1 = animal2; animal2 = temp; } } class Animal { String name; public Animal(String name) { this.name = name; } public String toString() { return name; } }
Output
Before Swap:- a1:Lion; a2:Crocodile After Swap:- a1:Lion; a2:Crocodile
Objects are not swapped because Java uses pass by value.

Example taken from Java Pass by Value

How do I know which verson goes with 'com.android.support:appcompat-v7:28.0.0'?

Is there any reasons why you need to know since it will automatically generated ?

This is mine (for Sdk 17)
apply plugin: 'com.android.application' android {     compileSdkVersion 27     defaultConfig {         applicationId "com.example.seng.sechandapp"         minSdkVersion 15         targetSdkVersion 27         versionCode 1         versionName "1.0"         testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     } } dependencies {     implementation fileTree(dir: 'libs', include: ['*.jar'])     implementation 'com.android.support:appcompat-v7:27.1.1'     ....... }

The implementation 'com.android.support:support-v4:23.4.0' is I copied from a sample frome a tutorial code which is a few years old.

Will you get any errors after you remove this?
