没有这样的服务ComponentInfo Android JobScheduler

Question

我正试图用JobScheduler计划一项作业，但我收到了一个异常，就好像我没有在AndroidManifest.xml中添加服务一样：

java.lang.IllegalArgumentException: No such service ComponentInfo{br.com.modeladoryoga.pontocorpofidelidade.ihm.servicos/br.com.modeladoryoga.pontocorpofidelidade.ihm.servicos.JobSchedulerService}

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:755)

构建：

JobScheduler mJobScheduler = (JobScheduler) context
.getSystemService(JOB_SCHEDULER_SERVICE);
JobInfo.Builder mJobBuilder =
new JobInfo.Builder(idServicoNotificacao,
new ComponentName(JobSchedulerService.class.getPackage().getName(),
JobSchedulerService.class.getName()));
mJobBuilder.setMinimumLatency(3000);
if (mJobScheduler != null && mJobScheduler.schedule(mJobBuilder.build())
<= JobScheduler.RESULT_FAILURE) {
Log.d(TAG_SERVICO, "Unable to schedule the service!");
}

AndroidManifest.xml：

...
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application 
...
<service android:name=".ihm.servicos.JobSchedulerService"
android:permission="android.permission.BIND_JOB_SERVICE"
android:exported="true"/>
<receiver android:name=".ihm.servicos.NotificationServiceStarterReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>

我试过几次跑步，但都没有成功。任何有过同样问题的人都可以帮助我吗？

Answer 1

使用new ComponentName(Context pkg, String cls)

JobScheduler mJobScheduler = (JobScheduler) context.getSystemService(Context.JOB_SCHEDULER_SERVICE);
JobInfo.Builder mJobBuilder = new JobInfo.Builder(idServicoNotificacao,new ComponentName(context,JobSchedulerService.class));
mJobBuilder.setMinimumLatency(3000);
if (mJobScheduler != null && mJobScheduler.schedule(mJobBuilder.build()) != JobScheduler.RESULT_SUCCESS) {
Log.d(TAG_SERVICO, "Unable to schedule the service!");
}

Answer 2

您可以使用getPackageName()作为ComponentName():的第一个参数

JobInfo.Builder mJobBuilder =
new JobInfo.Builder(idServicoNotificacao,
new ComponentName(getPackageName(),
JobSchedulerService.class.getName()));

Answer 3

我在android studio日志猫中也遇到了同样的错误，但我的应用程序正在运行。在Application类中实现Configuration.Provider，并覆盖其方法，如下代码片段中所示

@NonNull
@Override
public Configuration getWorkManagerConfiguration() {
return new Configuration.Builder().setMinimumLoggingLevel(100).build();
}

使用.setMinimumLoggingLevel(100)这种方法解决了我的问题。如果您使用的是workmanager，那么它会给出这样的错误。

Answer 4

之后

mJobBuilder.setMinimumLatency(3000);

插入

int ret = mJobScheduler.schedule(mJobBuilder.build());
if (ret<= JobScheduler.RESULT_FAILURE) {
Log.d(TAG_SERVICO, "Unable to schedule the service!");
}
