Put & Get Values with Intent | Sharing Data between Activities | Android Tutorial

 Sharing data between activities in Android is as simple as this.


Put Data

Intent intent = new Intent(MainActivity.this, BrowseActivity.class );
intent.putExtra( "targetUrl","https://www.google.com");
startActivity(intent);

Get Data
Intent intent = getIntent();
String targetUrl = intent.getStringExtra("targetUrl");

Here we put data in one activity. And retrieve the data in another activity.
So, we need to .java files.
Say, you have FirstActivity.java and SecondActivity.java file.
You put values in FirstActivity.java file. So, code to put data should go in this file:
Intent intent = new Intent(MainActivity.this, BrowseActivity.class );
intent.putExtra( "targetUrl","https://www.google.com");
startActivity(intent);
Now you retrieve the values in SecondActivity.java file. To retrieve information, use
Intent intent = getIntent();
String targetUrl = intent.getStringExtra("targetUrl");
This is really simple.
Obviously, you can use TextEdit Component to Put / Get these data.

// GetParcelableExtra
PollingStation pollingstation = getIntent().getParcelableExtra("objResponse");

Happy Coding!

[SOLVED] Is Android Studio supported on Mac OS 10.15 (Catalina)? Android Studio Not Working on MAC

 Technically Yes! But not that all versions work the same way. While I upgraded to Android Studio to Version 4.1.2. But it did not work in OS 10.15. I deleted my previous android installations following this guide , but still nothing seemed to work. The hell bent installer seemed to get stuck in the middle. I contacted few experts who also appear clueless. A lot of time in my developers' life, I prompt to self - "Read Sid, Read!'. This was no different this time. Instead of searching for help online / offline, I started reading the Android Studio Release Note for version 4.1.2 . It clearly says ,  System Requirements  For MAC:  Mac® OS X® 10.10 (Yosemite) or higher, up to 10.14 (macOS Mojave) So, it may not work with MAC OS Catalina anyway. And it did not work as in my case.
