Where to put gitIgnore file in Android Studio?

Question

I am developing an app and I must take that project to GitHub. Now, I must make gitIgnore file. I know that file is used to ignore some specified files from my project. I used gitIgnore.io service and I received generated file. This is my gitIgnore file:

# Created by https://www.gitignore.io/api/android

### Android ###
# Built application files
*.apk
*.ap_

# Files for the ART/Dalvik VM
*.dex

# Java class files
*.class

# Generated files
bin/
gen/
out/

# Gradle files
.gradle/
build/

# Local configuration file (sdk path, etc)
local.properties

# Proguard folder generated by Eclipse
proguard/

# Log Files
*.log

# Android Studio Navigation editor temp files
.navigation/

# Android Studio captures folder
captures/

# Intellij
*.iml
.idea/workspace.xml

# Keystore files
*.jks

### Android Patch ###
gen-external-apklibs

But I don't know were to copy this, and where to put that in my Android project. Could someone help me?

I copied this file into my gitIgnore file in Android Studio, but when I have pushed that project on gitHub my gitnigore file looks like this:

*.iml
.gradle
/local.properties
/.idea/workspace.xml
/.idea/libraries
.DS_Store
/build
/captures

So, that files that I copied into Android Studio are not here. What is the problem?

Answer 1

Normally when creating a new project the gitignore file is generated for you.

Here is the correct .gitignore file.

*.iml
.gradle
/local.properties
/.idea/workspace.xml
/.idea/libraries
.DS_Store
/build
/captures

This is were you have to put it.

Answer 2

.gitignore file must be in the root directory of the project not just in android projects but in any project types
