WorkManager:使用AlarmManager时如何处理网络约束？

Constraints constraints = new Constraints.Builder()
        .setRequiredNetworkType(NetworkType.UNMETERED)
        .build();

OneTimeWorkRequest workRequest = new OneTimeWorkRequest.Builder(MyWorker.class)
        .setConstraints(constraints)
        .build();

WorkManager.getInstance(context).enqueue(workRequest);

// 设置任务执行失败时的指数退避策略
WorkRequest workRequest = new OneTimeWorkRequest.Builder(MyWorker.class)
        .setConstraints(constraints)
        .setBackoffCriteria(BackoffPolicy.EXPONENTIAL, 10, TimeUnit.MINUTES)
        .build();

// 注册网络状态变化的广播接收器
IntentFilter filter = new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION);
context.registerReceiver(networkStateReceiver, filter);

// 广播接收器中监听网络状态变化
private BroadcastReceiver networkStateReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        // 更新任务的约束条件
        Constraints newConstraints = new Constraints.Builder()
                .setRequiredNetworkType(NetworkType.UNMETERED)
                .build();
        
        WorkManager.getInstance(context)
                .pruneWork()
                .enqueueUniqueWork("my_unique_work", ExistingWorkPolicy.KEEP, 
                        new OneTimeWorkRequest.Builder(MyWorker.class)
                                .setConstraints(newConstraints)
                                .build());
    }
};
