我有一份工作服务,我想要每三个小时一次,我已经完成了工作服务课程,但我不知道如何每三个小时执行一次。
这是我的Jobservice课程
public class CleanupJobService extends JobService {
private static final String TAG = CleanupJobService.class.getSimpleName();
@Override
public boolean onStartJob(JobParameters params) {
Log.d(TAG, "Cleanup job started");
new CleanupTask().execute(params);
//Work is not yet complete
return true;
}
@Override
public boolean onStopJob(JobParameters params) {
//No need to reschedule any jobs
return false;
}
/* Handle access to the database on a background thread */
private class CleanupTask extends AsyncTask<JobParameters, Void, JobParameters> {
@Override
protected JobParameters doInBackground(JobParameters... params) {
String where = String.format("%s = ?", DatabaseContract.TaskColumns.IS_COMPLETE);
String[] args = {"1"};
int count = getContentResolver().delete(DatabaseContract.CONTENT_URI, where, args);
Log.d(TAG, "Cleaned up " + count + " completed tasks");
return params[0];
}
@Override
protected void onPostExecute(JobParameters jobParameters) {
//Notify that the work is now done
jobFinished(jobParameters, false);
}
}
}
并在Manifest上注册
<service
android:name=".data.CleanupJobService"
android:permission="android.permission.BIND_JOB_SERVICE"
android:exported="true"/>
有什么想法解决这个问题吗?谢谢!
答案 0 :(得分:0)
解决了,我使用jobInfo类来解决这个问题,代码看起来应该是这样的
ComponentName jobService = new ComponentName(getContext(), CleanupJobService.class);
JobInfo task = new JobInfo.Builder(CLEANUP_JOB_ID, jobService)
.setPeriodic(jobInterval)
.setPersisted(true)
.build();
jobInterval是我们希望服务执行的预定义时间,类型为Long并且具有millis格式。
