How to ON/OFF battery doze mode in android

Hello, dear friends, this post is very important to the Android developers to resolve to avoid battery doze mode so let's start...


MainActivity.java

package com.samset.doze;

import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.AppCompatButton;
import androidx.appcompat.widget.AppCompatTextView;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;

import com.samset.doze.utils.DozeHelper;

public class MainActivity extends AppCompatActivity {
    private AppCompatButton btncheck;
    private AppCompatTextView tvmsg;

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btncheck=findViewById(R.id.btncheck);
        tvmsg=findViewById(R.id.tvmsg);


        tvmsg.setText("This app is " +DozeHelper.getisBatteryOptimizations(this,getPackageName().toString()));
        btncheck.setOnClickListener(new View.OnClickListener() {
            @Override            public void onClick(View view) {
                Intent intent= DozeHelper.prepareBatteryOptimization(MainActivity.this,getPackageName(),true);
                startActivity(intent);

            }
        });





    }
}

DozeHelper.java

public class DozeHelper {
