TextRecognizer.isOperational() API always returns false

Question

This question has been asked severally and only suggestions are made. Ill comprehend every suggestion hopefully.

the dependency is defined in the manifest

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version"/>

    <meta-data
        android:name="com.google.android.gms.vision.DEPENDENCIES"
        android:value="ocr" />

and added on the app level

compile 'com.google.android.gms:play-services-vision:9.8.0'

The test device has sufficient storage which is greater than 10% of the internal and also has a very good internet connection. Permissions are also clearly defined

We start the TextRecognizer to detect text and we get our null response:

 TextRecognizer textRecognizer = new TextRecognizer.Builder(getContext()).build();

    if (!textRecognizer.isOperational()) {

        Log.w("Main Activity", "Dependencies are not yet available");
        Toast.makeText(getContext(), "Cannot Detect", Toast.LENGTH_LONG).show();
        if(((MainActivity) getActivity()).hasLowStorage()) {
            Toast.makeText(getContext(), "Low Storage", Toast.LENGTH_LONG).show();
            Log.w("Custom_Storage", "Low Storage");
        }

    }

Most suggestions are to use a lower dependency compile 'com.google.android.gms:play-services:7.8+' but it doesn't work for everyone. After publishing the app, some users cant use the app.

The suggestions are not solving the problem.

TextRecognizer API is required to download few dependency files. Usually it is done at the time of installation but sometimes it take longer time. App will automatically download those files. Wait some time to download those files. Until download is complete TextRecognizer.isOperational will return false. After the doanlowd is completed TextRecognizer.isOperational will return true.
