从Gmail直接打开PDF触发Permission Denial权限拒绝问题求助

大家好，我现在遇到一个头疼的权限问题想请教各位：
我的PDF阅读器APP在打开已经下载到手机本地的PDF文件时完全正常，但直接从Gmail应用里打开PDF文件就会触发Permission Denial权限拒绝错误。

以下是我当前的相关配置和代码：

AndroidManifest.xml #

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.docreader">
    <!-- Wymagane uprawnienia do odczytu plików PDF -->
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION" />

    <application android:name=".MainApplication" android:label="@string/app_name" android:requestLegacyExternalStorage="true" android:icon="@mipmap/ic_launcher" android:roundIcon="@mipmap/ic_launcher_round" android:allowBackup="false" android:exported="true" android:theme="@style/AppTheme" android:supportsRtl="true">
        <activity android:name=".MainActivity" android:label="@string/app_name" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|screenSize|smallestScreenSize|uiMode" android:launchMode="singleTask" android:windowSoftInputMode="adjustResize" android:exported="true">
            <!-- Intent filter to handle PDF files -->
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <action android:name="android.intent.action.SEND" />
                <action android:name="android.intent.action.PICK" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <!-- Obsługuj pliki PDF: content:// i file:// -->
                <data android:mimeType="application/pdf" />
                <!-- <data android:scheme="content" android:mimeType="application/pdf" />
                <data android:scheme="file" android:mimeType="application/pdf" /> -->
                <data android:scheme="content" />
                <data android:scheme="file" />
            </intent-filter>
        </activity>
        <provider android:name="androidx.core.content.FileProvider" android:authorities="${applicationId}.fileprovider" android:exported="false" android:grantUriPermissions="true">
            <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" />
        </provider>
    </application>
</manifest>

app.json #

            Intent.ACTION_SEND -> intent.getParcelableExtra(Intent.EXTRA_STREAM)
            else -> null
        }

        if (uri != null) {
            try {
                val inputStream = contentResolver.openInputStream(uri)
                val file = File(cacheDir, "temp_imported.pdf")
                val outputStream = FileOutputStream(file)
                // 此处代码未粘贴完整
            } catch (e: Exception) {
                Log.e("MainActivity", "Error handling incoming file", e)
            }
        }
    }
}

想请教各位，这种从Gmail直接打开PDF触发的权限拒绝问题，可能是哪里配置出了问题？应该怎么修复？
