Call a service class Once in a day when application is Starts in android ,with less Battery Consumption

Question

I want to call a Service Class, when User Starts the Application Once in a Day in Android.

Manifest Code:

<service android:name=".DailyRemainder" >
            <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </service>

Java Code:

 // for Repeating Process
    Intent myIntent = new     Intent(sign_in.this,.DailyRemainder.class);
    pendingIntent1 = PendingIntent.getService(sign_in.this, 0,myIntent, 0);
   AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
   Calendar calendar = Calendar.getInstance();
     calendar.setTimeInMillis(System.currentTimeMillis());
     calendar.add(Calendar.SECOND, 20); alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent1);
  alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000, pendingIntent1);

Above code is running in background drains my Mobile Battery, but i need when user starts the Application that time Service Should Run Once in a Day. How to Achieve this.

Answer 1

the AlarmManager is only the feature that can wakeup your device 100%.

Any service doesn't consume your battery at all if it doesn't do any work. I think you have to read your code more carefully.

Nevertheless, some advice. You can call broadcast receiver instead of Service to wake up. That is, use

Intent intent = new Intent("yourBroadCastString");
PendingIntent pi = PendingIntent.getBroadcast(...);
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (currentapiVersion >= android.os.Build.VERSION_CODES.KITKAT){
            am.setExact(wakeup?AlarmManager.RTC_WAKEUP:AlarmManager.RTC, nexttime, pi);
        } else{
            am.set(wakeup?AlarmManager.RTC_WAKEUP:AlarmManager.RTC, nexttime, pi);
        }

in the case above am.setExact can really consume the battery,

to wakeup your device in this case you have to use inside broadcast:

PowerManager pm = (PowerManager) ctx.getSystemService(Context.POWER_SERVICE);
            wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |
                    PowerManager.ACQUIRE_CAUSES_WAKEUP |
                    PowerManager.ON_AFTER_RELEASE, _.APPNAME + Integer.toString(index));
        if (wakeLock != null && wakeLock.isHeld()){
            wakeLock.acquire();
        }

ComponentName comp = new ComponentName(ctx.getPackageName(),
                yourServiceClass.class.getName());
        startWakefulService(ctx, intent.setComponent(comp));

inside androidmanifest.xml

<receiver android:name="yourBroadCast">
        <intent-filter>
            <action android:name="yourBroadCastString"/>
        </intent-filter>
        </receiver>

And your code is really bad:

Omg, what the hell is this? Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); long t = calendar.getTimeInMillis(); I think you have to read your code.

I found the answer for my Question using Shared pref.

When Activity is Starting ,First time in a day Async task will run. then inside on Post execute todays date is saved.

after that async will not execute in a same day. I removed Alarm Manager part

// Shared Preferences
    SharedPreferences settingsShrepref;

    // Editor for Shared preferences
    SharedPreferences.Editor editor;
    // Sharedpref file name
    private static final String PREF_NAME = "MyPrefFileShred";

    // User name (make variable public to access from outside)
    public static final String KEY_TODAY_DATE_ANDTIME = "TimeToday";

Inside Oncreate Activity

    /* Added Servcie count Once in a day Fetch from Server*/

            try {

                DateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
                Date date = new Date();
                 TodayDate_String = dateFormat.format(date);


                settingsShrepref = getSharedPreferences(PREF_NAME, 0);
                editor = settingsShrepref.edit();

                String Val=settingsShrepref.getString(KEY_TODAY_DATE_ANDTIME,"");


                Log.i("Stored Val", Val);
                Log.i("Today date", TodayDate_String);
                if(!Val.equals(TodayDate_String))
                {

                    //for  SYNC web to Local
                    try
                    {
                        Log.d("Comments", "FirstTime Started");

                        // get Internet status
                        isInternetPresent = cd1.isConnectingToInternet();

                        // check for Internet status
                        if (isInternetPresent)
                        {
                            new AsyncCallWSCategoryCOUNTFetch().execute();

                        }
                        else {

                            Log.i("CATEGORY COUNT ", "Not Internet ......!");
                        }
                    }
                    catch (Exception e)
                    {
                        e.printStackTrace();
                        Log.i(" CATEGORY COUNT ", "EXCEPTION in reading Data from Web Async task ONstart ......!");

                    }


                }
                else
                {
                    Log.d("Comments", "Second TIme");

                    Getmethod();
                }
            } catch (Exception e) {
                e.printStackTrace();
                Log.i("", "Exception here Run Service.");
            }

Inside Async task On post Execute

@Override
        protected void onPostExecute(Void result)
        {
            Log.i(TAG_CategoryCOUNT, "onPostExecute");


            try {



                //the app is being launched for first time in a Day, do something
                Log.d("Comments", "First Time");

                // Storing name in pref
                editor.putString(KEY_TODAY_DATE_ANDTIME, TodayDate_String);
                // commit changes
                editor.commit();

                String Val=settingsShrepref.getString(KEY_TODAY_DATE_ANDTIME, null);
                Log.d("after Insertion data Date", Val);



            } catch (Exception e) {

                e.printStackTrace();
            }

        }
