TextRecognizer isOperational API始终返回false [英] TextRecognizer isOperational API always returns false

问题描述

我需要捕获图像的字符，因此我正在使用TextRecognizer.我的代码在下面给出

I need to capture characters of an image so i am using TextRecognizer. My code is given below

TextRecognizer textRecognizer = new TextRecognizer.Builder(mActivity.getGalleryApplication().getAndroidContext()).build();
if (!textRecognizer.isOperational()) {
    new AlertDialog.Builder(mActivity.getAndroidContext())
                                        .setMessage("Text recognizer could not be set up :(").show();
    return;
}
textRecognizer.release();

我在build.gradle中添加了依赖项，如下所示:

I have added dependencies in build.gradle as below:

    dependencies {
        compile 'com.google.android.gms:play-services-maps:10.2.1'
        compile 'com.google.firebase:firebase-appindexing:10.2.1'
        compile 'com.android.support:appcompat-v7:23.0.0'       
    }

每次启动apk时，都会显示无法设置文本识别器:.即使我已设置所有依赖项，但仍然出现此错误.请帮助为什么TextRecognizer.isOperational()始终为假.

Everytime I launch the apk, "Text recognizer could not be set up : is displayed. Even though I have set all dependencies but still i am getting this error. Please help why TextRecognizer.isOperational() is always false.

我有一个项目要在下周末完成.请帮助解决此错误.

I have a project to be completed by next weekend. Please help to solve this error.
