JobScheduler

任务写在JobService中

public class TestJobService extends JobService {

    private static final String TAG = "SyncService";

    @Override

    public void onCreate() {

        super.onCreate();

        Log.i(TAG, "Service created");

    }

    @Override

    public void onDestroy() {

        super.onDestroy();

        Log.i(TAG, "Service destroyed");

    }

    @Override

    public boolean onStartJob(JobParameters params) {

        // fake work

        Log.i(TAG, "on start job: " + params.getJobId());

        return true;

    }

    @Override

    public boolean onStopJob(JobParameters params) {

        Log.i(TAG, "on stop job: " + params.getJobId());

        return true;

    }

    public void scheduleJob(JobInfo info){

        Log.i(TAG, "schedule job ");

        JobScheduler js=(JobScheduler)getApplication().getSystemService(Context.JOB_SCHEDULER_SERVICE);

        js.schedule(info);

    }

}

设置调度的相关条件

...

mServiceComponent = new ComponentName(this, TestJobService.class);

...

public void scheduleJob(View v){

        JobInfo info=new JobInfo.Builder(sJobId,mServiceComponent)

            //延迟

            .setMinimumLatency(2000)

            //最长延迟

            .setOverrideDeadline(5000)

            //所需网络类型  本例中 为需要无线网络

            .setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED)

            .setRequiresDeviceIdle(true)

            .setRequiresCharging(true)

            .build();

        JobSchedulerjobScheduler=(JobScheduler)getApplication().getSystemService(Context.JOB_SCHEDULER_SERVICE);

        jobScheduler.schedule(info);

    }

如何获取正在运行的所有程序的名称

public String getRunningProcessNames(){

        ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);

        List<ActivityManager.RunningAppProcessInfo> l = am.getRunningAppProcesses();

        PackageManager pm = this.getPackageManager();

        StringBuilder sb=new StringBuilder();

        for(ActivityManager.RunningAppProcessInfo i:l){

            try{

                CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(i.processName, PackageManager.GET_META_DATA));

                sb.append(c.toString()+'\n');

            }catch (Exception e){

                e.printStackTrace();

            }

        }

        return sb.toString();

    }
