Camera allow doesn't work android webview

I am trying to create a webview app. I tried to add the access to manifest but it didn't change anything. On the chrome browser the camera works, I can't understand what should I do.
1. This is the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="i.astiapp.astiappadmindev">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" android:required="true" />
<uses-feature android:name="android.hardware.camera.front" android:required="true" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />
<!-- My Location -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:screenOrientation="portrait"
android:name=".MainActivity">
</activity>
<activity
android:hardwareAccelerated="true"
android:name=".SplashActivity"
android:screenOrientation="portrait"
android:theme="#style/SplashTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" /></intent-filter>
</activity>
</application>
</manifest>
2. Main Activity
import android.graphics.Bitmap;
import android.os.Build;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.webkit.PermissionRequest;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
public class MainActivity extends AppCompatActivity implements MyWebChromeClient.ProgressListener{
private ProgressBar chromeProgressBar;
WebView myWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myWebView = (WebView) findViewById(R.id.webview);
//chromeProgressBar = (ProgressBar) findViewById(R.id.progressBarChrome);
//Settings
WebSettings webSettings = myWebView.getSettings();
myWebView.getSettings().setTextSize(WebSettings.TextSize.NORMAL);
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
webSettings.setAllowUniversalAccessFromFileURLs(true);
webSettings.setAllowFileAccessFromFileURLs(true);
}
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setAllowFileAccess(true);
//webSettings.setLoadsImagesAutomatically(true);
//inizialize client
//load website by URL
myWebView.loadUrl("https://www.voyage-app.eu/asti-app/admin/index.php");
//register token for notification
// this.onStart();
chromeProgressBar = (ProgressBar) findViewById(R.id.progressBar);
myWebView.setWebChromeClient(new WebChromeClient() {
// Grant permissions for cam
#Override
public void onPermissionRequest(final PermissionRequest request) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
request.grant(request.getResources());
}
}
});
myWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
chromeProgressBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
chromeProgressBar.setVisibility(View.GONE);
}
});
}
#Override
public void onUpdateProgress(int progressValue) {
chromeProgressBar.setProgress(progressValue);
if (progressValue == 100) {
chromeProgressBar.setVisibility(View.INVISIBLE);
}
}
public class WebViewController extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
#Override
public void onBackPressed()
{
if(myWebView.canGoBack())
myWebView.goBack();
else
super.onBackPressed();
}
}
I don't think I should post the PHP file since on the chrome browser the page works. It happens like this:
You enter the page
Chrome browers asks you to give you the permission to the camera
The camera starts working

Fixed it. I had to add the permession to the code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
int hasCameraPermission = checkSelfPermission(Manifest.permission.CAMERA);
List<String> permissions = new ArrayList<String>();
if (hasCameraPermission != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.CAMERA);
}
if (!permissions.isEmpty()) {
requestPermissions(permissions.toArray(new String[permissions.size()]), 111);
}
}
But for this to work I had to add the manifest file too:
import android.Manifest;

Ad isn't loading

I followed the google tutorial on interstitial ads, but whenever I try to display my ad it never is loaded. I've tried to use AdListener instead of interstitial.isLoaded, but still the same result. I've also given the ad over 2 minutes to load a couple times, so something must be wrong.
I am using an AVD, could that be the problem? It can connect to the Internet just fine when I use the browser though.
removed an incorrect link

if(loaded) {
interstitial.show();

} else {

}
}
});
return showed;
}
}

If you got this error:
could not find com.google.android.gms.ads.AdActivity, please make sure
it is declared in AndroidManifest.xml
Then adding this activity declaration within the <application> tag in your Manifest should fix it:
<activity android:name="com.google.android.gms.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

Why it can run in my device but it didn't display the map?I am beginner of SDK please explain clearly

This is my MainActivity
it is wrong about level of API ??
i am using Google API
API level 18
package com.example.map;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MapView myMap = (MapView) findViewById(R.id.mapView);
final MapController controller = myMap.getController();
LocationManager manager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
LocationListener listener = new LocationListener(){
#Override
public void onLocationChanged(Location location) {
controller.setCenter(new GeoPoint((int)location.getLatitude(),(int)location.getLongitude()));
}
#Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onStatusChanged(String provider, int status,
Bundle extras) {
// TODO Auto-generated method stub
}
};
manager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, listener);
}
}
This is my Manifest
The uses_permission is necessary ??
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
This is my activity_main
My layout is it correct??
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>

If you're seeing a grayed tile background where a map should be, you are likely using the wrong api key. You need a production key for a device that is different from the debug key for the map api.
