Google Speech-to-Text API - 安卓应用程序崩溃

Question

我是新手，我正在尝试使用link 中提到的 Google Speech-to-Text API。我已按照他们提到的步骤操作，并在创建服务帐户后将 credentials.json 放在所需的文件夹中。我生成了一个签名的 apk 以在 android 设备上运行它，但每次我说什么它都会崩溃。我检查了它给我这个错误的日志：

我应该如何解决这个问题？

Answer 1

可能您没有添加包含以下内容的库：org.apache.commons.codec.binary.Base64

您可以创建自己的方法：

解码数据：

    // decode data from base 64
    private static byte[] decodeBase64(String dataToDecode)
    {
        byte[] dataDecoded = Base64.decode(dataToDecode, Base64.DEFAULT);
        return dataDecoded;
    }

编码数据：

    //enconde data in base 64
    private static byte[] encodeBase64(byte[] dataToEncode)
    {
        byte[] dataEncoded = Base64.encode(dataToEncode, Base64.DEFAULT);
        return dataEncoded;
    }

希望它会有所帮助。
