How I do text detection from image using google vision api?

Question

I new the Android code side and I have a project.

I want text detection from ımage using google vision api, but I cannot.

I search the internet but I can't find enough information and I know I should use Json(AsynTack).

Just want this not face detection,logo detection.

How can I do this, can you suggest anything?

The Vision API consists of a single endpoint (https://vision.googleapis.com/v1/images) that supports one HTTP request method (annotate). Here is a sample JSON request:

POST https://vision.googleapis.com/v1/images:annotate

{
  "requests":[
    {
      "image":{
        "content":"change_this_to_the_path_of_your_image"
      },
      "features":[
        {
          "type":"LABEL_DETECTION",
          "maxResults":1
        }
      ]
    }
  ]
}

Here is the fork of Google sample code, working mainly for text detection.

Just use Android Studio to open the project in the folder

cloud-vision/android/CloudVision/

I think this is what you really need:

//Google code labs for mobile vision https://codelabs.developers.google.com/codelabs/mobile-vision-ocr/#0

Do let me know if this info helps.
