Question

我已经创建了BroadcastReceiver类，但是它不是由我的意图触发的。在清单文件中注册了BroadcastReceived和intent关系，但看来我做错了。我的代码设置不正确吗？在手机启动时启动BOOT意图还是在应用启动时触发？

广播接收的类：

public class NetworkSchedulerReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("receiver","test receiver"); // ----------> this doesn't log :(

        JobInfo networkJob = new JobInfo.Builder(0, new ComponentName(context, NetworkSchedulerService.class))
                .setRequiredNetworkType(JobInfo.NETWORK_TYPE_ANY)
                .setPersisted(true)
                .build();

        JobScheduler scheduler = (JobScheduler) context.getSystemService(Context.JOB_SCHEDULER_SERVICE);
        scheduler.schedule(networkJob);
    }
}

我已经通过下面提到的方式做到了。

首先创建广播接收器类。

class BroadcastReceiverOnBootComplete: BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) {
    if (intent?.action.equals(Intent.ACTION_BOOT_COMPLETED, ignoreCase = true)) {

       // Do something here.
      }
   }
 }

像这样在您的AndroidManifeast文件中注册接收器

 <receiver
        android:name=".receiver.BroadcastReceiverOnBootComplete"
        android:enabled="true"
        android:exported="false">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.PACKAGE_REPLACED" />
            <data android:scheme="package" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.PACKAGE_ADDED" />
            <data android:scheme="package" />
        </intent-filter>
    </receiver>

希望有帮助。

广播接收器不会被BOOT_COMPLETED意图触发
