Android Studio Marshmallow

Android 6.0 Marshmallow, also known as Android M, is the sixth major version of the Android operating system. It was released in October 2015, and features several important updates and improvements over its predecessor, Android 5.0 Lollipop.

Syntax

To start developing applications for Android 6.0, you will need to download and install the latest version of Android Studio. Here is the basic syntax for creating an Android application using Android Studio Marshmallow:

public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   }
}

Example

Let's take a look at a simple example that demonstrates how to use the new runtime permissions feature in Android 6.0.

// Check for runtime permissions
public void checkPermissions(){
   if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
           != PackageManager.PERMISSION_GRANTED) {
       ActivityCompat.requestPermissions(this,
               new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 999);
   }
}

// Handle permission results
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
   if (requestCode == 999) {
       if (grantResults.length > 0
               && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
           // Permission granted
       } else {
           // Permission denied
       }
   }
}

Output

The output of the above example will show a dialog prompting the user to grant permission for external storage access. Depending on the user's response, the application will either be granted or denied access.

Explanation

The above code checks for runtime permissions for writing to external storage. Since Android 6.0 introduced the new runtime permissions feature, it is important to check for permissions on-the-fly rather than requesting them all at once at installation time. This approach provides a better user experience and improves security.

The checkSelfPermission() method checks if the specified permission is granted to the application. If it is not, the requestPermissions() method requests the specified permissions. The onRequestPermissionsResult() method handles the user's response to the permission request.

Use

Android Studio Marshmallow is used to develop Android applications for devices running Android 6.0 and later. It includes updated tools and features for developing, debugging, and testing Android applications. You can use Android Studio Marshmallow to create applications that take advantage of the new runtime permissions system, improved app standby mode, and other new features introduced in Android 6.0.

Important Points

  • Android Studio Marshmallow is the latest version of Android Studio.
  • It includes tools and features for developing applications for Android 6.0 and later.
  • New features in Android 6.0 include: runtime permissions, app standby mode, and improved battery life.
  • Applications developed using Android Studio Marshmallow can take advantage of these new features.

Summary

Android Studio Marshmallow is an essential tool for developing Android applications for devices running Android 6.0 and later. The new runtime permissions system and other updated features in Android 6.0 make it even more important to use the latest version of Android Studio for creating new applications.
