1. 创建POJO照片

公开课堂照片{

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;



public long getId() {
    return id;
}

public void setId(long id) {
    this.id = id;
}

private Blob blobImage;

public Blob getBlobImage() {
    return blobImage;
}

public void setBlobImage(byte[] bytes) {
    this.blobImage = new Blob(bytes);
}

private String name;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

private String type;

public String getType() {
    return type;
}

public void setType(String type) {
    this.type = type;
}

公共字节[]decodeBlobImage（）{return com.google.api.client.util.Base64.DecodeBase64(blobImage)；}

在您的活动中执行此操作

                Photo photo = new Photo();
    Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
    R.drawable.sherlock);
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
    byte[] byteArray = stream.toByteArray();
    photo.encodeBlobImage(byteArray);
    photo.setName("Sherlock");
    photo.setName("sherlock");
    photo.setType("image/jpeg");
    photo.setId((long) 8232);
    Photoendpoint.Builder builder = new Photoendpoint.Builder(
    AndroidHttp.newCompatibleTransport(), new JacksonFactory(),
            null);
    builder = CloudEndpointUtils.updateBuilder(builder);

    Photoendpoint endpoint = builder.build();

    Log.d("Exception", "inserting image");
    try {
        Log.d("Exception", "inserting");
        endpoint.insertphoto(photo).execute();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        Log.d("Exception", "" + e);
    }
