Android Studio Dex Error

Question

so I've just starting playing around with Android Studio and working on an App, pretty basic stuff so far and I'm trying to parse data from a HTML file to my app, I ran across some issues and been googling around for the past few hours and couldn't fix it after all.

Here's the error log:

Here's my app gradle:

apply plugin: 'com.android.application'

android {
    useLibrary 'org.apache.http.legacy'
    compileSdkVersion 26
    defaultConfig {
        applicationId "app.diviwire.transportes"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner     "android.support.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),     'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/NOTICE.txt'

        exclude 'META-INF/ASL2.0'
        exclude 'META-INF/README.md'
        exclude 'META-INF/CHANGES'
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    compile 'com.android.support:support-compat:26.1.0'
    compile 'com.android.volley:volley:1.0.0'
    // jsoup HTML parser library @ https://jsoup.org/
    compile 'org.jsoup:jsoup:1.11.2'
    compile 'com.android.support:multidex:1.0.1'
}

Tell my if there's something else missing, not sure what to add more since I'm just starting. Thanks in advance guys!

EDIT: So I've followed @IntelliJ Amiya suggestion and apparently it's still not working, I've probably done something wrong but here's my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="app.diviwire.transportes">

<uses-permission android:name="android.permission.INTERNET" />

<application
    android:name="android.support.multidex.MultiDexApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainMenuActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".BoatMenuActivity" />
    <activity android:name=".HorarioBarcoBarreiroActivity" />
</application>

And I also added the following to my Activity:

@Override
protected void attachBaseContext(Context base){
    super.attachBaseContext(base);
    MultiDex.install(this);
}

It's still giving me the same error.

@duggu yea I have tried all that, Cleaning, Rebuilding, Restarting the IDE... — Wireless
@IntelliJAmiya I've added the multiDexEnabled true statement and the compile but I had some issues with the rest since I'm just starting but will look into it more deeply — Wireless
@IntelliJAmiya alright, you've helped enough already :D Thanks — Wireless

You reached maximum memory allocation pool for a Java Virtual Machine (JVM) for dex operation so you have to increase the size of pool memory.

Just you have added below code in an android project, build.gradle file.

dexOptions{
javaMaxHeapSize "4g"
}

it is just an option to specify the maximum memory allocation pool for a Java Virtual Machine (JVM) for dex operation.

4g is 4 Gigabytes and this is a maximum heap size for dex operation.
