Question about file importing on web view

[RafaelGomes00]

Hello, and thanks for the plugin.

I am currently trying to implement a file upload feature for a remotely hosted website inside the WebView.

I based my implementation on the example branch for #1179, which works fine but explicitly requires runtime permissions for Camera, Microphone, and Audio. For my specific project use case, I do not want to request camera or microphone permissions from the user. I only need standard file/gallery access to allow uploading images and/or videos.

However, whenever I remove the camera/microphone permissions from the AndroidManifest.xml and set webViewObject.SetCameraAccess(false), clicking the file input button inside the remote website does absolutely nothing, the Android file chooser window fails to appear.

Is there any workaround to allow standard uploads from remote websites without declaring or requesting Camera and Microphone permissions?

Thank you in advance.

Regarding code, the SampleWebView is the same present on the example branch. And the following is my manifest.

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

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="28" />
    
    <uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" /> 
    
    <application
        android:requestLegacyExternalStorage="true"
        android:allowBackup="false"
        android:hardwareAccelerated="true"

        <activity android:name="com.unity3d.player.UnityPlayerActivity"
                  android:theme="@style/UnityThemeSelector">

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
        </activity>
        <!--Used when Application Entry is set to GameActivity, otherwise remove this activity block-->
        <activity android:name="com.unity3d.player.UnityPlayerGameActivity"
                  android:theme="@style/BaseUnityGameActivityTheme">
            <intent-filter>

        </activity>
    </application>
</manifest>

Thanks for the report. I have pushed the tweaked plugin code and the sample app to:

https://github.com/gree/unity-webview/commits/example-for-1218/

where I avoided

• using the camera intent (d52cd4d)
• requiring the camera permission 678bef8

I'll update the master branch later, but it may take a while.
