In this post we will see how to use browser intent.

In app if you want to open url i.e. website in phones browser.
then Browser Intent is used.

the link will open in Phone’s default browser.

if user installed other browser app
then it will show list of browser to select one of them.

lets get started .

1. open android studio

2. create a new project.

3. Set application name Browser Intent

4. I used package path as com.androidcodr.browserintent click next.

5. On this screen set minimum sdk API 16 click next.

6. Add empty activity. click next.

7. keep Activity name as MainActivity click finish. wait till project load completely.

8. Goto activity_main.xml

9. if you are having constrainLayout change it to RelativeLayout

10. add a button at center of screen.

set its properties as follows.

text=Open google
padding=20dp
textSize=16sp
onClick=openurl
layout_margin=20dp
id=@+id/mainbtnopen

Android Browser Intent
    <Button
        android:text="Open google"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:id="@+id/mainbtnopen" />

11. change property of helloworld textview

text=”Click button¬†below to open www.google.com”
textSize=”18sp”
layout_above=”@+id/mainbtnopen”
gravity=”center_horizontal”
layout_margin=”10dp”

 

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Click button below to open www.google.com"
        android:textSize="18sp"
        android:layout_above="@+id/mainbtnopen"
        android:gravity="center_horizontal"
        android:layout_margin="10dp" />

12. open MainActivity.java
add method openurl for button

    public void openurl(View view) {
       
    }

13. define proper url in String
lets open google

 

String url = "http://www.google.com";

13. define new Intent which will open our url.
ACTION_VIEW

 

Intent i = new Intent(Intent.ACTION_VIEW);

14. use setdata method to pass Uri.
parse string to it.

 

i.setData(Uri.parse(url));

15. finally startintent

 startActivity(i);

16.so your full method will look like this.

 public void openurl(View view) {
        String url = "http://www.google.com";
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(url));
        startActivity(i);
    }

17. Build your Project and run.

21. if you dont want button. you can use simple textview.

to look textview is clickable we will draw under line to text.

22. first add Textview below our button.
set its properties as follows

text=”Yahoo”
layout_below=”@+id/mainbtnopen”
id=”@+id/maintvyahoo”
OnClick=”openyahoo”
textSize=”18sp”

    <TextView
        android:text="Yahoo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/mainbtnopen"
        android:layout_centerHorizontal="true"
        android:id="@+id/maintvyahoo"
        android:onClick="openyahoo"
        android:textSize="18sp" />

23. now declare field textview in MainActivity.

 

    TextView tvyahoo;

24. in method OnCreate initialize textview.

tvyahoo = (TextView)findViewById(R.id.maintvyahoo);

25. now we will use sentPaintFlag method to draw under line.

 

tvyahoo.setPaintFlags(tvyahoo.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

26. now add method openyahoo
just like we added for button.

 

change url to http://www.yahoo.com

here is method.

 

 public void openyahoo(View view) {
        String url = "http://www.yahoo.com";
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(url));
