Android emulator web cam is not detected - android

I am new to android development. I am creating Scandit barcode scanner application which is using android emulator's camera (webcam).
I have configured camera permissions related stuffs in AndroidManifest.xml file as below:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="AndroidDemo.AndroidDemo" android:installLocation="auto">
<uses-sdk android:minSdkVersion="10" />
<application android:label="AndroidDemo"></application>
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-feature android:name="android.hardware.camera.autofocus" />
</manifest>
Now the logcat showing the following error:
07-21 13:21:03.026 E/EmulatedCamera_QemuClient( 63): queryStart: Query failed: Cannot start the camera
07-21 13:21:03.026 E/EmulatedCamera_QemuDevice( 63): startDevice: Unable to start device 'AndroidEmulatorVC0' for NV21[640x480] frames
Initially it was working fine.now i didnt change any code but it is not working. The camera functionality is randomly working.I am not sure how to troubleshoot this.
And my emulator config is given below(visual studio):
And related question is not answered
Thanks.

Android App requests more permissions than in manifest specified

Im confused. My Manifest looks like this (App-Name removed):
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="2" android:versionName="0.8.2" package="com.xxxxxxx.xxxx" android:installLocation="auto">
<uses-sdk android:minSdkVersion="26" android:targetSdkVersion="30" />
<application android:label="LABEL" android:theme="#style/MainTheme" android:usesCleartextTraffic="true"></application>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
But if I open the "permission" page in App-Store, it shows that the App "may use" storage permission.
My App doesnt need any access to external storage. Why this permission is listet in the store (and also in the app-settings after installation)?
How can I remove this? Its confusing for the users.

Permission Not Granted by Manifest (Api Level 22)

I am trying to log some actions to /sdcard. My AndroidManifest.xml specifies android:targetSdkVersion="22" and includes
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="<REDACTED-MYPACKAGENAME>"
android:versionCode="100"
android:versionName="1.00">
<uses-sdk android:targetSdkVersion="22"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
More...
Unfortunately, my writes to /sdcard/events.txt cause exception
java.io.FileNotFoundException: /sdcard/events.txt: open failed: EACCESS (Permission denied)
Notes:
Since the API level is <23, I believe run-time-permissions are not required.
If I manually enable "Storage" using "Settings"->"Apps->MyApp->"Permissions", it works just fine.
I am running on a Samsung S-9 running Android V10.
What am I missing?

Looks it was not a big problem because they accepted my app 3 days later .. So you just need to be patient !
