How to Allow Calls on Button Click in Android Web View App? - java

I am building an Android app and I am newbie.
I am not able to make calls by clicking a button inside android webview app
Here is my code:

I am new and still learning basics. Please help me to allow the phone calls in webview on this activity. So when someone clicks on phone number it should call, thanks.

This is How it works for me:
package com.example.myapplication;
import android.net.Uri;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.app.Activity;
import android.content.Intent;
public class MainActivity extends Activity {
private static final String TEL_PREFIX = "tel:";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView wv = (WebView) findViewById(R.id.webview);
wv.setWebViewClient(new CustomWebViewClient());
wv.loadUrl("https://google.pk");
WebSettings webSettings = wv.getSettings();
webSettings.setJavaScriptEnabled(true);
}
private class CustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView wv, String url) {
if(url.startsWith(TEL_PREFIX)) {
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}
return false;
}
}
}

First you would need to bind your javascript code to your android code, this guide demonstrates how to do that. Then in your javascript, you could add a listener to your button that invokes a Java method.
Second, you need to integrate a calling solution into your app this guide explains what options you have and how you can implement them.
Once you implemented the calling solution, you could simply make a call from the Java method that you intend to invoke from your javascript.

Android Webiew does not load indexed Sdcard (file://sdcard)

When I tried to access (file:///sdcard/) using mobile browsers (ex. Firefox, Opera ..etc). It shows me an index page for the SDCard (see the screenshot).

How to add spinner loading for every pags loading in webview

I am a beginner and building webview app with splash screen in AIED.
I want to add spinner loading for every page loading in webview. I mean when this webview loads after the splash screen, I can see home page of website when I open any other page. While loading that page I want to show spinner in the center of screen. When the page load the spinner should disappear.
I not know where to add the specific code.
Here is mainactivity.java

Big Caveat: This solution won't completely hide the white screen(loading) on websites that has to download and load .js files especially if they are big.
First, you are using onPageFinished incorrectly. onPageFinished is always going to be called after every page load has finished. This means if you are navigating on your website, it will call onPageFinished every after you navigate a URL and the webview has finished loading it.
Here's an idea on how to do this:
First create an HTML page and design on how you want your spinner would look like. Save the HTML template as a string HTMLSpinner.
Then create a second webview and load the HTML template string to it
public WebView spinner;
spinner.loadData(HTMLSpinner, "text/html", "UTF-8");
Then modify your main mWebView.setWebViewClient like this
mWebView.setWebViewClient(new WebViewClient(){
#Override
public void onPageStarted(WebView view, final String url, Bitmap favicon) {
mWebView.setVisibility(View.GONE);
spinner.setVisibility(View.VISIBLE);
// YOUR LANDING PAGE
if(url.equals("https://www.mominbaba.com")){
mWebView.setVisibility(View.GONE);
mSplashView.setVisibility(View.VISIBLE);
}
}
#Override
public void onPageFinished(WebView view, String url) {
mWebView.setVisibility(View.VISIBLE);
spinner.setVisibility(View.GONE);
// YOUR LANDING PAGE
if(url.equals("https://www.mominbaba.com")){
mWebView.setVisibility(View.GONE);
mSplashView.setVisibility(View.VISIBLE);
}
}
});
That should swap the current webview that you see from the main webview to the loader. I have chosen to use a second webview because the asset that was given to was an animated SVG.

Why can't I use getActivity()

My question is why can't I use getActivity method in the following code. I'm trying to upload image with webView. It's my first Android application. I want to create an app for my classified osclass site.
When I build the app I get the following message:
error: cannot find symbol method getActivity().
Please change my code, and paste in Answer or write where should I put your code (or change).

You don't need to do getActivity() since you are already in the activity. You should just be able to do getApplicationContext()
Toast.makeText(getApplicationContext(), "Cannot Open File Chooser", Toast.LENGTH_LONG).show();

can we make two launcher activities and launch one based on some condition?

my launcher activity is loginActivity and i want that when the user selects a college and opens the app for the second time he should be moved to another activity TestYip (and not login activity). that is the launcher activty should change once the user has logged in. for this i made a fuction getCollege in Select_Collage activity which is called from the loginActivity .
but its not working.. the code is given :

please tell how i can move from one activity to another based on a condition.

Dont use LoginActivity as your launcher activity. In your LoginActivity, save some flag value to SharedPreferences to indicate the user has logged in, and then in the onCreate of your other Activity(Set this one to launcher), check for this value, if its not present, then go to LoginActivity.

I will recommend the best way around. Whenever you are stuck on such things, Splash screen will help you.
Let me explain how:-
Just make splash screen as Launcher activity. If you don't want that to display it for much longer, just have the handler run for 1-2 seconds. Now look at the code below.
SplashScreen.java
public class SplashScreen extends AppCompatActivity {
private String email;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_splash);
//SharedPreference to Store API Result
SharedPreferences pref = getApplicationContext().getSharedPreferences("CachedResponse", 0);
SharedPreferences.Editor editor = pref.edit();
editor.apply();
email = pref.getString("login", null);
int SPLASH_TIME_OUT = 3000;
if (email != null) {
//It means User is already Logged in so I will take the user to Select_College Screen
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(SplashScreen.this, Select_College.class);
intent.putExtra("Email", email);
startActivity(intent);
finish();
}
}, SPLASH_TIME_OUT);
} else {
//It means User is not Logged in so I will take the user to Login Screen
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(SplashScreen.this, Login.class);
startActivity(intent);
finish();
}
}, SPLASH_TIME_OUT);
}
}
}
Login.java
public class Login extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_doctor_login);
//SharedPreference to Store API Result
pref = getApplicationContext().getSharedPreferences("CachedResponse", 0);
Login();
}
private void login() {
//If login is successfull, before moving to next activity, store something in sharedpreference with name login. It can be email or just a string as "true"
SharedPreferences.Editor editor = pref.edit();
editor.putString("login", email);
editor.apply();
Intent intent = new Intent(DoctorLogin.this, Select_Collage.class);
intent.putExtra("Email", email);
startActivity(intent);
finish();
}
}
Select_Collage.java
public class Select_Collage extends AppCompatActivity {
private SharedPreferences pref;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_doctor_message);
//SharedPreference to Store API Result
pref = getApplicationContext().getSharedPreferences("CachedResponse", 0);
//Somewhere on Signout button click, delete the login sharedpreference
signOut();
}
private void signOut() {
SharedPreferences.Editor editor = pref.edit();
editor.remove("login");
editor.apply();
Intent intent = new Intent(Select_Collage.this, Login.class);
startActivity(intent);
finish();
}
}
So that's how you can solve this problem. Keep Coding :)

Try saving a boolean or int in shared preference.
Set the int or boolean in Select_collage
Get its value in LoginAcitivity , and check condition the way you did it.
I guess the problem with your code is when you check condition in LoginAcitivity , the value in Select_collage activity is not set as it is not created.
https://developer.android.com/training/basics/data-storage/shared-preferences.html

You have to start a splashcreen activity.. in that activity u need to check the condition (oncreate function)
for which activity should be launch to the next..

We Keep Coding
