I have converted my fully responsive website in to Android app using Android studio. I have also added one signal push notification. I have two questions.
Notification works fine but I want the notification to be opened in a separate window when I click it. what should be the code and where should I put those?
I want a page loading progress bar in my webview app (android studio).what should be the code and where should I put those?
My codes are as follows.
At mainactivity.java page
package com.example.rijvan.awebaddress;
import...
public class MainActivity extends AppCompatActivity {
public WebView mywebView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
OneSignal.startInit(this)
.inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification)
.unsubscribeWhenNotificationsAreDisabled(true)
.init();
setContentView(R.layout.activity_main);
mywebView=(WebView)findViewById(R.id.webview);
WebSettings webSettings=mywebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mywebView.loadUrl("https://my web site/");
mywebView.setWebViewClient(new WebViewClient());
}
@Override
public void onBackPressed() {
if (mywebView.canGoBack()){
mywebView.goBack();
}else{
super.onBackPressed();
}
}
}
At activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.constraint.ConstraintLayout>
At AndroidManifest.xml

I am really new in Android. Any help would be greatly appreciated.
Try this code it will help you to load webview.
webView = (WebView) findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
webView.getSettings().setDomStorageEnabled(true);
final ProgressDialog pd = ProgressDialog.show(TestView.this, "", "Loading...", true);
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.diamondflorist.com/");
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
pd.show();
}
@Override
public void onPageFinished(WebView view, String url) {
pd.dismiss();
}
});
and for notification you need to create a new Activity or dialog whatever you want and open this by clicking notification like this.
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(icon, message, when);
Intent notificationIntent = new Intent(context, HomeActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, title, message, intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, notification);
Hope this helps you;
Find the answer below:
1. I want a page loading progress bar in my webview app (android studio). what should be the code and where should i put those ? Try these code will work-
package com.example.rijvan.awebaddress;
import android.annotation.SuppressLint;
import android.os.Build;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.support.v7.app.AppCompatActivity;
import android.view.KeyEvent;
import android.view.View;
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 {
private WebView webView;
private ProgressBar progressBar;
@SuppressLint("HandlerLeak")
private Handler handler = new Handler() {
@Override
public void handleMessage(Message message) {
switch (message.what) {
case 1: {
webViewGoBack();
}
break;
}
}
};
@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webview);
progressBar = findViewById(R.id.progress_bar);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
webView.setLayerType(View.LAYER_TYPE_HARDWARE, null);
} else {
webView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// TODO: 5/28/2018 set your loader progress here
}
});
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
progressBar.setVisibility(View.VISIBLE);
return true;
}
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
});
webView.loadUrl("https://my web site/");
progressBar.setVisibility(View.VISIBLE);
webView.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
handler.sendEmptyMessage(1);
return true;
}
return false;
}
});
}
private void webViewGoBack() {
webView.goBack();
}
}
2. Notification works fine but i want the notification to be opened in a separate window when I click it. what should be the code and where should i put those ?
You can do it by passing url in one signal notification- 1. send page url in the notification for which you want to open on notification click.
pass that url in notification intent, for example:
NotificationManager notificationManager = (NotificationManager) context .getSystemService(Context.NOTIFICATION_SERVICE); Notification notification = new Notification(icon, message, when);
Intent notificationIntent = new Intent(context, MainActivity.class); notifcationIntent.putString(URL, pageUrl); notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0); notification.setLatestEventInfo(context, title, message, intent); notification.flags |= Notification.FLAG_AUTO_CANCEL; notificationManager.notify(0, notification);
In your MainActivity get the page url from the intent and load that url in webview.ex-
if (null != getIntent() && null != getIntent().getExtras()) { Bundle bundle = getIntent().getExtras(); String url = bundle.getString(URL); loadWebview(url);
