我的日志显示它由于onError（）函数中生成的错误9而停止。

我正在尝试运行此示例程序以尝试熟悉Speech Recognizer软件。

这可能是由于我在Android Studio而非实际设备上运行它而引起的问题吗？我对此很固执。

Answer 1

ERROR_INSUFFICIENT_PERMISSIONS当google没有record_audio权限时也会抛出错误9 。

检查设置 -> 应用程序 -> Google -> 权限 -> 麦克风

Android 的最新版本要求像 RECORD_AUDIO 这样的权限被认为是 PERMISSION_DANGEROUS，不仅需要在 AndroidManifest.xml 中声明该权限：

但在运行时，用户必须使用“requestPermission”授予权限（如 Marky 的回答中所述）

Answer 2

如果有人遇到这个问题，而其他答案都无济于事，则您可能想尝试使用以下代码请求权限：

private void requestRecordAudioPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        String requiredPermission = Manifest.permission.RECORD_AUDIO;

        // If the user previously denied this permission then show a message explaining why
        // this permission is needed
        if (checkCallingOrSelfPermission(requiredPermission) == PackageManager.PERMISSION_DENIED) {
            requestPermissions(new String[]{requiredPermission}, 101);
        }
    }
}

Answer 3

这只是模拟器不支持它的问题。它可以在物理设备上运行。
