如何修复空对象引用上的 DroidSpeech 代码？

Question

我是开发安卓应用的新手。

我想使用 DroidSpeech (https://github.com/vikramezhil/DroidSpeech)

此代码在 [Android 10] 上运行良好。但是，[Android 11] 显示以下错误。

DroidSpeech.java

private void startLanguageReceiver()
    {
        Log.i("CONTEXT", context.toString());
        Intent languageDetailsIntent =  RecognizerIntent.getVoiceDetailsIntent(context);

        languageDetailsIntent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);


        LanguageReceiver languageReceiver = new LanguageReceiver();
        languageReceiver.setOnLanguageDetailsListener(new OnLanguageDetailsListener() {
            @Override
            public void onLanguageDetailsInfo(String defaultLanguage, List<String> otherLanguages) {

                dsProperties.currentSpeechLanguage = defaultLanguage;
                dsProperties.supportedSpeechLanguages = otherLanguages;

                // Initializing the droid speech properties
                initDroidSpeechProperties();

                if(droidSpeechListener != null)
                {
                    // Sending an update with the current speech language and supported speech languages if applicable
                    droidSpeechListener.onDroidSpeechSupportedLanguages(dsProperties.currentSpeechLanguage, dsProperties.supportedSpeechLanguages);
                }
            }
        });

        // Starting the broadcast receiver to get the language details
        context.sendOrderedBroadcast(languageDetailsIntent, null, languageReceiver, null, Activity.RESULT_OK, null, null);
    }

这是错误代码

    java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Intent android.content.Intent.addFlags(int)' on a null object reference
        at com.example.Jachi3kki.DroidSpeech.DroidSpeech.startLanguageReceiver(DroidSpeech.java:108)
        at com.example.Jachi3kki.DroidSpeech.DroidSpeech.<init>(DroidSpeech.java:83)
        at com.example.Jachi3kki.fragment.ViewPagerMainFragment.onCreate(ViewPagerMainFragment.kt:42)

DroidSpeech.java:108 这个

Intent languageDetailsIntent =  RecognizerIntent.getVoiceDetailsIntent(context);

DroidSpeech.java:83

startLanguageReceiver();

我试图修复它但失败了。

好像所有变量都初始化了，但是哪里出错了。

我该如何解决？

Answer 1

要为 Android 11 解决此问题，请按照以下步骤操作

第 1 步：Download DroidSpeech.java 第 103 行的代码压缩和更改

替换这个：Intent languageDetailsIntent = RecognizerIntent.getVoiceDetailsIntent(context);

有了这个：Intent languageDetailsIntent = Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

第 2 步：将com.vikramezhil.droidspeech 包复制到我的项目并更改应用gradle

替换这个：compile 'com.github.vikramezhil:DroidSpeech:v2.0.3’

有了这个：implementation project(path: ':droidspeech')
