我如何解决Python.getInstance（）错误，当我在android Studio中使用chaquopy

Question

我试图在android工作室中使用chaquopy来识别视频中的音频并将其转换为文本，但当我调用Python时。getInstance（）以红色覆盖。可能有什么问题？。

build.gradle（应用程序）

plugins {
    id 'com.google.gms.google-services'

    //for chaquopy(python)
    id 'com.android.application'
    id 'com.chaquo.python'
}


android {
    compileSdk 31

    defaultConfig {
        applicationId "com.talhakara.uzaktanegitimbitirmeprojesi"
        minSdk 16
        targetSdk 30
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
       // for chaquopy(python)
        ndk {
            abiFilters "armeabi-v7a", "arm64-v8a", "x86", "x86_64"
        }
        python {
            buildPython "C:/Users/enest/AppData/Local/Programs/Python/Python39/python.exe"

        }

        sourceSets {
            main {
                python.srcDir "src/main/python"
            }
        }
        //
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {

        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildFeatures {
        viewBinding true
        dataBinding true
    }
}

  @Override

        super.onCreate(savedInstanceState);
        binding = ActivityVideoConferenceBinding.inflate(getLayoutInflater());
        View view = binding.getRoot();
        setContentView(view);

        //start python
        if (! Python.isStarted()) {
            Python.start(new AndroidPlatform(VideoConference.this));
        }

        Python py = new Python.getInstance(); // this line is red and 
                                              //it doesn't show any errors
                                             
        binding.btnChooseVideo.setOnClickListener(view1 -> {

            callChooseFromVideo();

        });



    }

这是gradle版本的问题吗？因为我的gradle版本7.0.4在chaquopy的文档里显示7.0是最新的。它会导致这个问题吗？我使用10.0.1作为chaquopy版本，因为android studio推荐它作为最新版本。如果这些都是问题，我应该使用哪个版本？

Answer 1

正确的语法是Python。getInstance（），而不是新的Python.getInstance（。
