android JDBC mysql java connector app:preDexDebug

Question

I'm trying to learn how to use the JDBC to connect a application to a MySQL database.

I'm using the Android Studio.

I downloaded "mysql-connector-java-5.1.37" from the MySQL website.

Just for put the "mysql-connector-java-5.1.37-bin.jar" in libs folder of a Hello World application and compile I receive :

Error:Execution failed for task ':app:preDexDebug'. com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:Program FilesJavajdk1.8.0_45injava.exe'' finished with non-zero exit value 1

the build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "br.com.myaplication.helloworld"
        minSdkVersion 15
        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 'com.android.support:appcompat-v7:23.1.0'
}

Try to sync your project Tools -> Android -> Sync Project with Gradle Files

And then rebuild your project: build -> rebuild project
