This is in Java

Use to check the github commits

We are chechecking these functions:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.i("Activity1", "onCreate");
    }

    @Override
    protected void onStart() {
        super.onStart();
        Log.i("Activity1", "onStart");
    }

    @Override
    protected void onResume() {
        super.onResume();
        Log.i("Activity1", "onResume");
    }

    @Override
    protected void onPause() {
        super.onPause();
        Log.i("Activity1", "onPause");
    }

    @Override
    protected void onStop() {
        super.onStop();
        Log.i("Activity1", "onStop");
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        Log.i("Activity1", "onDestroy");
    }

    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i("Activity1", "onRestart");
    }

👉 Step 1:

Create an empty activity app. You can run it on a device.

👉 Step 2:

Modify the MainActivity.java file ovveride tha activity's methods. Use the following package to log:

import android.util.Log;

Add a Log into onCreate:

Log.i("Activity1", "onCreate");

Ovveride the other methods with the log:

 @Override
    protected void onStart() {
        super.onStart();
        Log.i("Activity1", "onStart");
    }

    @Override
    protected void onResume() {
        super.onResume();
        Log.i("Activity1", "onResume");
    }

    @Override
    protected void onPause() {
        super.onPause();
        Log.i("Activity1", "onPause");
    }

    @Override
    protected void onStop() {
        super.onStop();
        Log.i("Activity1", "onStop");
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        Log.i("Activity1", "onDestroy");
    }

    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i("Activity1", "onRestart");
    }

👍 Finally you can check the app, the logs will be visible in LogCat. Use the tag Activity1 to filter the logcat.
