NoSuchMethodError: No static method decodeBase64

Question

I'm developing Marathi chatbot, in this I'm using Google Translator API and Speech to text. Till yesterday app was working fine but after restarting Android Studio, this error has occurred.

My app is working in AVD and only one device which is rooted. I tried in other 10 15 devices, the application shows error "Unfortunately App has stopped"

Answer 1

implementation 'commons-codec:commons-codec:1.10'

private String decodeBase64(String data) {
      byte[] bytes = new org.apache.commons.codec.binary.Base64().decode(StringUtils.getBytesUtf8(data));
      return new String(bytes);
}

Answer 2

I'm not sure but I think you have excluded json in you gradle . so Please try to implement only com.google.cloud:google-cloud-translate

implementation('com.google.cloud:google-cloud-translate:1.62.0')
annotationProcessor 'com.google.cloud:google-cloud-translate:1.62.0'

Answer 3

I think the problem lies in your GoogleCredentials Just see if they have been changed???? Just go and look for it...

Answer 4

create method decodeBase64

private String decodeBase64(String coded){
    byte[] valueDecoded= new byte[0];
    try {
        valueDecoded = Base64.decode(coded.getBytes("UTF-8"), Base64.DEFAULT);
    } catch (UnsupportedEncodingException e) {
    }
    return new String(valueDecoded);
}
