I have issue with this code.I am trying to display all devices that are connected on the same WIFI in the list.
I did debugging and it shows that connection with WIFI was made but it does not detect any devices, even though there are some connected devices for sure. I did pinging with both sides with computer and android and connection was made.
If you guys have any ideas where could be a problem, please let me know, cause I am out of ideas.

SOLUTION (by Varma Lanke):
https://gist.github.com/codedamage/8f98e2ed13d1d1fa05e5d43e67ea3e6c
private WebView htmlWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
htmlWebView = (WebView)findViewById(R.id.webview);
htmlWebView.setWebViewClient(new CustomWebViewClient());
WebSettings webSetting = htmlWebView.getSettings();
webSetting.setJavaScriptEnabled(true);
webSetting.setDisplayZoomControls(true);
htmlWebView.loadUrl("https://yatln.com/appdev365/index.php");
}
private class CustomWebViewClient extends WebViewClient{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.contains("appdev365"))
view.loadUrl(url);
else{
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(i);
}
// view.loadUrl(url);
return true;
}
}
For you should use shouldOverrideUrlLoading method, once try the below one
private WebView htmlWebView;
String url = "https://yatln.com/appdev365/index.php";
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainpage);
htmlWebView = (WebView)findViewById(R.id.webView);
if(url.contains("appdev365"))
htmlWebView.setWebViewClient(new CustomWebViewClient());
WebSettings webSetting = htmlWebView.getSettings();
webSetting.setJavaScriptEnabled(true);
webSetting.setDisplayZoomControls(true);
htmlWebView.loadUrl(url);
}
private class CustomWebViewClient extends WebViewClient{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(url.equalsIgnoreCase("appdev365"))
view.loadUrl(url);
return true;
}
}
This code opens browser and specified link (ex. google.com):
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

I have not yet written codes to upload the image on firebase database. All I am trying to do right now is to display the image I picked from gallery in the imageview of my app. However, like I said before it's not displaying anything right now and as soon as I choose some photo from gallery it collapses. Any help regarding the issue would be very appreciated.
I think there is no issue with your image picker code, what i found a problem is that you are using mProgressDialog without initializing it in the onCreate() method. So what is recommend is that you first initialize mProgressDialog object in your onCreate() method right after you the initialization of mImageView. And i hope that your application will not collapse now.
