One strategy for mitigating this problem is using a not-so-well-known API titled sendOrderedBroadcast (used in place of sendBroadcast) available on any Context within your application. In light of this question, I created a sample project to demonstrate one such approach to this problem. The same callbacks are presented in all scenarios. Whether the app is actively running or not, the developer is responsible for presenting notifications to the user.

In Android, the developer has full control over the lifecycle and presentation of a notification, and such, it could be presented at any time.

This is largely a fundamental difference in how Android handles notifications altogether. It’s true, there is no intrinsic differentiation for foreground and background notifications in Android.

“How do I detect if an Application is in the foreground when a notification arrives? Android seems to be missing this functionality, where iOS has it readily available.” paraphrased In a recent article I wrote for objc.io detailing how notifications in Android differ from those in iOS, a reader messaged me and asked Simulating background / foreground notifications in Android (Even if the value hasn’t been written to disk yet).īoth of these projects are open-sourced under the Apache license, and are available at our Github page. It also gives you a bunch of desirable consistency and concurrency characteristics – access can happen from any number of threads concurrently, and doing a write followed by a read will always return the value you just put. Remember takes care of that by putting a write-through cache in front of SharedPreferences. SharedPreferences are useful but since they’re backed by disk, they can have unpredictable performance characteristics – you’re not guaranteed to always be in memory, and in the case of write operations, you have to hit disk (possibly asynchronously) and remember what you wrote. So we built a little wrapper that’ll do this for you.Īn in-memory data store backed by shared preferences. Check it out: BookendsĪ UI widget that allows for headers and footers on lists backed by RecyclerView.Īs we were upgrading our app to migrate from ListView to RecyclerView, we found it kind of silly that RecyclerView doesn’t support headers by default. We’ve open-sourced a couple of Android utilities that we use in the Tumblr app for Android.
