An error occurred when network connection is lost during fetching of image. Using the method below.

reCaptcha.showChallengeAsync(myRecaptchaPublicKey, this);

Hi, your library looks great! But it's a hassle to integrate it to modern Gradle-based projects. Can you please publish the jar to jcenter? It's really easy.

Don't you think that
reCaptcha.verifyAnswerAsync("your-private-key", "user-input", onVerifyAnswerListener);
Is kinda useless? And shouldn't be provided in the API since it leaks "your-private-key"?

By following the installation documentation on importing reCAPTCHA via Gradle

repositories {
    jcenter()
}

dependencies {
    compile 'android.lib.recaptcha:reCAPTCHA:+'
}

I encounter an error on upon building project

Error:Execution failed for task ':app:processDebugManifest'.

Hi ayltai,

I am having issues building the codes that's provided in the recaptcha-samples folder with reference to Google's reCAPTCHA V2 API. I kept receiving this error message
"Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/lib/recaptcha/ReCaptcha$1.class"

I would really appreciate your advise to this issue, thank you.

Here are my codes:

apply plugin: 'com.android.application'


android {
    compileSdkVersion 25
    buildToolsVersion "26.0.2"
    defaultConfig {
        applicationId "android.lib.recaptcha.samples"
        minSdkVersion 14
        targetSdkVersion 25
        versionCode 1
        versionName "1.0.0"
        multiDexEnabled true

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'android.lib.recaptcha:reCAPTCHA:2.0.0'


}

I tried to reload the captcha once a user entered a wrong answer, I use this code:

ReCaptcha reCaptcha = (ReCaptcha)findViewById(R.id.recaptcha);
reCaptcha.showChallenge(SITE_KEY);

then it throws NetworkOnMainThreadException. I tried running it inside AsyncTask, then an error notice appears saying that showChallenge() must be called from the UI thread, currently inferred thread is worker...

any suggestion?

How to make simpler captcha, please.

Hi, I am trying to use this library. However, I found out there is no support for me to verify the CAPTCHA answer on my own server. What I'm trying to do is to send the API request from my server to google and get the response. But one of the parameter to pass is the challenge which your library doesn't let me achieve it. I wonder if you can please do a little modification so I can get the challenge and pass that to my server. Or do you have a suggestion for me?

All links referring to CAPTHCA and "sign up for ur api key" lead to 404. The sign up link should be https://www.google.com/recaptcha/admin
