我只是想在我的 java android 应用程序中添加 google Vision API。作为一部分,当我尝试将位图转换为图像时,我得到一个异常如下......
java.lang.NoSuchMethodError: No static method encodeBase64URLSafeString([B)Ljava/lang/String; in class Lorg/apache/commons/codec/binary/Base64; or its super classes (declaration of 'org.apache.commons.codec.binary.Base64' appears in /system/framework/org.apache.http.legacy.boot.jar)
at com.google.api.client.util.Base64.encodeBase64URLSafeString(Base64.java:79)
at com.google.api.services.vision.v1.model.Image.encodeContent(Image.java:98)
我的gradle文件如下……

}
根据我在谷歌上的发现这个问题是由于 android-support 指向一个旧的通用版本,其中确实没有“encodeContent”方法。
我的代码将位图转换为图像……
public Image getBase64EncodedJpeg(Bitmap bitmap) {
com.google.api.services.vision.v1.model.Image image = new com.google.api.services.vision.v1.model.Image();
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, byteArrayOutputStream);
byte[] imageBytes = byteArrayOutputStream.toByteArray();
image.encodeContent(imageBytes);
return image;
}
任何人都可以帮助我解决这个问题......任何建议都对我有用..
1)更新/添加/添加运行时依赖项我项目中的通用版本。--- 如果可能的话,在我的选择中最好....
2)以其他方式从位图转换为Base64EncodedJpeg ...
任何帮助都可以得到...
