No field INSTANCE of type Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier; in class Lorg/apache/http/conn/ssl/AllowAllHostnameVerifier

I am making a simple KeyAuth app on Android and using this API as an example: https://github.com/SprayDown/KeyAuth-JAVA-api
Below are the function I've been trying to work on and the gradle file for the application.
HttpResponse<String> response;
try {
response = response = Unirest.post(url).field("type", "init").field("ver", version)
.field("name", appname).field("ownerid", ownerid).asString();
} catch (UnirestException e) {
e.printStackTrace();
}
Above is the code I've been trying to run and getting the error. And here is my gradle file:

Wonder what's going wrong with this.

I'm getting an error when building my APK

I'm getting this error when I try to build my APK. I'm currently mantaining and buf-fixing this app from another developer. In the gradle he used .+ in every compile. How can I fix it?

Remove all of the "+" in your libraries dependency's
version
Try this in your app level gradle file
implementation('com.github.bumptech.glide:glide:4.6.1') {
exclude group: 'com.android.support'
}`
if it does not solve try logging dependencies run this command
./gradlew -q dependencies app:dependencies --configuration compile
in your android studio's Terminal Tab it will log all the dependency tree of your project
then find which libraries are using duplicating dependencies
for example
implementation 'com.github.bumptech.glide:glide:4.6.1'
is using duplicate dependencies so change
implementation 'com.github.bumptech.glide:glide:4.6.1'
to
implementation('com.github.bumptech.glide:glide:4.6.1') {
exclude group: 'com.android.support'
}

Execution fail for task ':app:transformClassesWithJarMergingForDebug'

Add this to your build.gradle :

}
It worked for me

You are adding a library like this
(A). compile files('libs/YOUR_LIBRARY.jar')
and this library package already available in your code.
comment it like or remove this line
//compile files('libs/YOUR_LIBRARY.jar')
How to know duplicate-copy of library in your project:
unzip your "YOUR_LIBRARY.jar" and see the same class name in your code.

Unable to use the apache.poi library after adding gradle dependency

I've been trying to use the apache.poi library to create an excel file but, for some reason, I'm unable to import anything.
mainClassName = 'Main'
sourceCompatibility = 1.7
targetCompatibility = 1.7
version = '1.0'
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.api-client:google-api-client:1.22.0'
compile 'com.google.oauth-client:google-oauth-client-jetty:1.22.0'
compile 'com.google.apis:google-api-services-sheets:v4-rev21-1.22.0'
compile 'org.apache.poi:poi:3.9'
}
When I am trying to write import org.apache.poi; it gives me an error saying "Package does not exist".
What is wrong with my dependencies? Thanks.

Some times it is useful to reload a gradle project so gradle could download the binary of the new dependency. After that the new packages should be available.

Found the same error while including gradle in the build.gradle file.
Use:
compile group: 'org.apache.poi', name: 'poi', version: '3.9'
Like: dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile group: 'org.apache.poi', name: 'poi', version: '3.9'
compile 'com.android.support:appcompat-v7:23.4.0'
}
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "fl.gauravsngarg.com.inventory"
minSdkVersion 23
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile group: 'org.apache.poi', name: 'poi', version: '3.9'
compile 'com.android.support:appcompat-v7:23.4.0'
}

After research I found the actual version.
Use
// https://mvnrepository.com/artifact/org.apache.poi/poi
compile group: 'org.apache.poi', name: 'poi', version: '3.9'
Its given here
https://mvnrepository.com/artifact/org.apache.poi/poi/3.9
The site contains all the official dependencies for gradle, maven, etc.

It worked for me:
It is quite possible that you have enabled gradle sync in offline mode.
Just change that.
Works like a charm

I had the same issue!
For me File > Invalidate Chaches / Restart > Invalidate and Restart worked.
I am using this version: https://mvnrepository.com/artifact/org.apache.poi/poi/4.1.2

Worked for me:
compile group: 'org.apache.poi', name: 'poi-ooxml', version: '4.0.0'
