如果在 AndroidManifest.xml 中设置了 android:sharedUserId，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.speechrecognizerapp"
    android:sharedUserId="com.example.speechrecognizerapp">

    <uses-permission android:name="android.permission.RECORD_AUDIO" />

    <queries>
        <intent>
            <action android:name="android.speech.RecognitionService" />
        </intent>
    </queries>
    ...

SpeechRecognizer 在 Android 11（API 级别 30）上不起作用，因为 RecognitionListener.onError 回调将返回 5 (SpeechRecognizer.ERROR_CLIENT)。

如果您检查 logcat，它表明我们不允许执行 RECORD_AUDIO：

但是 SpeechRecognizer 在删除 sharedUserId 并重新安装应用程序后确实有效。如您所知，您无法从应用市场将具有 sharedUserId 的 App 升级到没有 sharedUserId 的较新版本，因此我不知道如何正确解决此问题。请帮帮我。
