android-workmanager

问题 I recently migrated my old app's background services to WorkManager. On recent devices (down to sdk 22 included ) it looks OK, running repeating work units and scheduling them even across device reboots as expected. The problem is when I test against old version (old is very relative here), Android sdk 14 which is my minSdkVersion . BTW also WorkManager should have the same: Backwards compatible up to API 14 according to doc. As stated in title, error I get is : java.lang.RuntimeException:

问题 I'm creating OneTimeWorkRequest with NetworkType.CONNECTED constraint, but even though the device is connected to the internet, the request is still in ENQUEUED state Constraints constraints = new Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build(); OneTimeWorkRequest request = new OneTimeWorkRequest.Builder(SyncWorker.class) .setConstraints(constraints) .build(); WorkContinuation continuation = mWorkManager.beginUniqueWork("work", ExistingWorkPolicy.KEEP, request);

问题 I've had a look at the codelab for WorkManager plus some examples on here, but everything in code I have seen is either related to doing work locally on the device or work uploading to the server, not downloading data and responding to the data received. In the developer guidelines it even says, "For example, an app might need to download new resources from the network from time to time," so I thought it would be perfect for this task. My question is if WorkManager can handle the following
