Keeping A Background Service Alive On Android

In reference to Accelerometer seems to only work for a few seconds? I'm using the BOOT_COMPLETED broadcast event to call the following: public class OnBootReceiver extends Broadcas

Solution 1:

All you have to do to have a service that is constently alive is:

<!-- BackGroundService Service --><serviceandroid:name="com.settings.BackgroundService"android:enabled="true"android:exported="false"android:process=":my_process" />

2) onStartCommand should return:

return Service.START_STICKY;

and that's all buddy after I Start the service from the main activity it is on for the whole day/

Solution 2:

You need to use a Partial Wakelock with the service. If your service is interactive with the user, you might consider making the service foreground.

This is a working example for a Partial Wakelock:

Use this when service is started:

PowerManagerpm= (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    PowerManager.WakeLockcpuWakeLock= pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);
    cpuWakeLock.acquire();

When the service is stopped, do call cpuWakeLock.release();

imports android.support.v4.content.WakefulBroadcastReceiver which Android Studio is telling me doesn't exist.

You need to import the support library for that.

Solution 3:

To do the trick use JobScheduler and JobService which allow you to execute code periodically.

First create a class that extends JobService, then implement required methods and add your service code/start another service from within the JobService onStartJob() method.

Here's an example for executing a JobService operation periodically:

ComponentNameserviceComponent=newComponentName(context, yourJobService.class);
JobInfo.Builderbuilder=newJobInfo.Builder(0, serviceComponent);
builder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED); 
builder.setRequiresDeviceIdle(false); 
builder.setRequiresCharging(false); 
builder.setPeriodic(60000); // <<<<----  60 seconds intervalJobSchedulerjobScheduler= (JobScheduler)context.getSystemService(Context.JOB_SCHEDULER_SERVICE);
jobScheduler.schedule(builder.build());

Good luck!
