The new JobService must be registered in the Android manifest with the BIND_JOB_SERVICE permission.
<service
android:name=".TestJobService"
android:label="Word service"
android:permission="android.permission.BIND_JOB_SERVICE" >
</service>
Create the receiver
Create the following utility class.
package com.vogella.android.localservice;
import android.app.job.JobInfo;
import android.app.job.JobScheduler;
import android.content.ComponentName;
import android.content.Context;
public class Util {
// schedule the start of the service every 10 - 30 seconds
public static void scheduleJob(Context context) {
ComponentName serviceComponent = new ComponentName(context, TestJobService.class);
JobInfo.Builder builder = new JobInfo.Builder(0, serviceComponent);
builder.setMinimumLatency(1 * 1000); // wait at least
builder.setOverrideDeadline(3 * 1000); // maximum delay
//builder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED); // require unmetered network
//builder.setRequiresDeviceIdle(true); // device should be idle
//builder.setRequiresCharging(false); // we don't care if the device is charging or not
JobScheduler jobScheduler = context.getSystemService(JobScheduler.class);
jobScheduler.schedule(builder.build());
}
}
Create the following receiver
package com.vogella.android.localservice;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class MyStartServiceReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Util.scheduleJob(context);
}
}
Register the receiver in the Android manifest for the BOOT_COMPLETED event.
<receiver android:name="MyStartServiceReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Create your job
package com.vogella.android.localservice;
import android.app.job.JobParameters;
import android.app.job.JobService;
import android.content.Intent;
/**
* JobService to be scheduled by the JobScheduler.
* start another service
*/
public class TestJobService extends JobService {
private static final String TAG = "SyncService";
@Override
public boolean onStartJob(JobParameters params) {
Intent service = new Intent(getApplicationContext(), LocalWordService.class);
getApplicationContext().startService(service);
Util.scheduleJob(getApplicationContext()); // reschedule the job
return true;
}
@Override
public boolean onStopJob(JobParameters params) {
return true;
}
}
