On this page: https://developer.android.com/training/app-links/deep-linking, in the
'Read data from incoming intents'
section, Google mentions:
Once the system starts your activity through an intent filter, you can
use data provided by the Intent to determine what you need to render.
Call the getData() and getAction() methods to retrieve the data and
action associated with the incoming Intent.
And that's exactly what I'm trying to do, but, I'm unable to get help.
In this activity of mine:
package com.application;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
#SuppressWarnings("unused")
public class SplashActivity3 extends Activity
{
Handler Handler;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash3);
Handler = new Handler();
Handler.postDelayed(new Runnable()
{
#Override
public void run()
{
Intent intent = new Intent(SplashActivity3.this, MainActivity.class);
startActivity(intent);
finish();
}
},
1500);
Intent appLinkIntent = getIntent();
String appLinkAction = appLinkIntent.getAction();
Uri appLinkData = appLinkIntent.getData();
}
}
I want to know (later tranfer it to another activity), the URL that was clicked on to open my app.
Basically, my app is using App Links (referred to as Deep Linking by some). So, in a case where a user 'A', sends user 'B' a link of a page on my website and B has my app installed, he/she will be able to open the link in my app instead of the browser.
As of now, B can open the link in my app, but, my app will always load the 'home page' (it's because I have coded my app to open the home page by default). I want to load the page that brought B in my app.
For a real life example, just like Facebook's app does. Suppose I share a link of a Facebook page or a profile to my friend. It's a standard HTTP link that's displayed in my web browser. Probably, I shared it with him on WhatsApp. He touches the link to open it. He has the official Facebook app installed on his phone. So, Android asks him if he wants to open the link in the Facebook app or in the browser. Now, when he chooses the browser, it's no problem at all. But, when he chooses the Facebook app, the app loads the profile or the page that exists on the link and not the home page of Facebook. That's what I want to achieve.
Please note, I'm talking about standard HTTP links here and not my app specific URIs.
UPDATE:
Here's something I tried now:
This is the same activity as above, I modified it like this:
package com.application;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
#SuppressWarnings("unused")
public class SplashActivity3 extends Activity
{
Handler Handler;
#Override
protected void onCreate(Bundle savedInstanceState)
{
final Intent appLinkIntent = getIntent();
final String appLinkAction = appLinkIntent.getAction();
Uri appLinkData = appLinkIntent.getData();
final Bundle bundle = new Bundle();
bundle.putString("web", appLinkAction);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash3);
Handler = new Handler();
Handler.postDelayed(new Runnable()
{
#Override
public void run()
{
Intent intent = new Intent(SplashActivity3.this, WebViewActivity.class);
intent.putExtras(bundle);
startActivity(intent);
finish();
}
},
1500);
}
}
And the activity in which I'm loading the URL:

I have removed AdMob from my source code of Android Studio, but still, it's showing an empty space at the bottom in the app.
It's always occupying an empty space at the bottom. I do not know how to make that bottom space disappear completely and show a normal preview of the app without ads.
How can I do this?
Here is the code.

I am stuck at the last phase of my project. I am developing a android webview app in which user can share the current loaded page in there social apps. My share button is in the top at the toolbar. Currently I am able to share the loaded url through the share button but when I jump to a new page and press share button, still initial loaded url is shared. Here I need to share the current url from the toolbar menu.

You should set WebViewClient with your webview like below:
WebView webview = new WebView(context);
webview.setWebViewClient(new WebViewClient()
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
Log.d("WebView", "your current url when webpage loading.." + url);
}
#Override
public void onPageFinished(WebView view, String url) {
Log.d("WebView", "your current url when webpage loading.. finish" + url);
super.onPageFinished(view, url);
}
#Override
public void onLoadResource(WebView view, String url) {
// TODO Auto-generated method stub
super.onLoadResource(view, url);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
System.out.println("when you click on any interlink on webview that time you got url :-" + url);
return super.shouldOverrideUrlLoading(view, url);
}
});
You can get current loaded url from shouldOverrideUrlLoading() .
I have an activity with a basic WebView. In that, I have a menu item which launches a Share intent and allows users to share the URL that they were browsing at that point of time. I also have an error HTML page which is loaded when the WebView gets any HTTP error. So, basically, I want the Share menu item to be hidden (or at least share some other URL that I can set) when that error document is loaded.

Regarding hiding the share menu icon, you could always use onPrepareOptionsMenu() to hide your share menu if there is an error flag.
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
menu.findItem(R.id.share).setVisible(!isPageError);
return true;
}
which would require you to have a isPageError boolean set to true in your
#Override
public void onReceivedError(WebView webview, int i, String s, String s1{
isPageError = true;
}
I solved it using moving my error page to another activity. This is my new MainActiviy.java:

I have a Question I'm new in android app development.

String userAgent = mWebView.getSettings().getUserAgentString();
mWebView.getSettings().setUserAgentString(userAgent);
WebSettings webSettings = mWebView.getSettings();

public void onBackPressed() {

MainActivity.this);
// set title

// set dialog message
alertDialogBuilder
.setMessage("Do you really want to exit KoriDev?")
.setCancelable(false)
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, close
// current activity
MainActivity.this.finish();
}
})
.setNegativeButton("No",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
}
I will try to read the version from the realtime database here:
case R.id.KoriAbout:
Toast.makeText(MainActivity.this, "Version: 0.3b", Toast.LENGTH_LONG).show();
But I don't know how to setup this with the Realtime Database from Firebase.
A picture from my database :
its real time by default...I believe. if you change it in firebase, it'll change it on your app. but, for what you have, you have it hard coded into your toast.
You need to do something like this:
FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference myRef = database.getReference("version");
// Read from the database
myRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
// This method is called once with the initial value and again
// whenever data at this location is updated.
String value = dataSnapshot.getValue(String.class);
Log.d(TAG, "Value is: " + value);
}
#Override
public void onCancelled(DatabaseError error) {
// Failed to read value
Log.w(TAG, "Failed to read value.", error.toException());
}
});
Checkout their doc here:
https://firebase.google.com/docs/database/android/start/
Can anyone please help me check my code to see why it cannot be
launched in the app itself but directs me to a browser? ): Thanks!!

MY APP VIEW CLIENT. JAVA

import android.content.Intent;
import android.net.Uri;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MyAppWebViewClient extends WebViewClient {

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
Where is the error? :D
It keeps opening up in the browser.
In the following line:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
you're asking Android to open a URL using the intent constant ACTION_VIEW - so it defaults to the external browser.
Here a full example (taken from here) that shows how to open the url using a WebViewClient:
package com.paresh.webviewclientdemo;
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
/*
* Demo of creating an application to open any URL inside the application and clicking on any link from that URl
should not open Native browser but that URL should open in the same screen.
*/
public class WebViewClientDemoActivity extends Activity {
/** Called when the activity is first created. */
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
web = (WebView) findViewById(R.id.webview01);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.google.com");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
// To handle "Back" key press event for WebView to go back to previous screen.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
web.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
