android-8.0-oreo

In Android Oreo, AccountManager.getAccountsByType("com.google"); returns null . Its, working fine in below Android 8 versions. Below is my code: private static Account getAccount(AccountManager accManager) { Account[] accounts = accManager.getAccountsByType("com.google"); Account account; if (accounts.length > 0) { account = accounts[0]; } else { account = null; } return account; } Thanks in advance. As per Android's update, from Oreo onwards we can not use AccountManager.getAccountsByType to get the list of google accounts configured on user's device, as they have updated the Google SignIn

I am working on a media app. I wonder how I can keep some old behavior my app has prior to Oreo, for example, have the notification and the service (for playback) hang in there even if the service is no longer set to foreground. We call startService(MediaPlaybackService.class) to start the service when playback starts, then create a notification and call startForeground() with it on the service. So far so good - if user exits the app, user will still have media play in the background and can control the playback from the notification. When user pauses playback, we call stopForeground(false) to

I registered notification channel in Android app following GoogleSamples https://github.com/googlesamples/android-NotificationChannels However how can I get notification channel Id from RemoteMessage, so I can set it to NotificationBuilder. public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService { @Override public void onMessageReceived(RemoteMessage remoteMessage) { //int id = remoteMessage.getNotificationChannel(); // -something like this I could not find } I found this value in RemoteMessage object value[3]="notification_channel_system", so I can

Background Before Android O, in order to get an app size, you had to have a special permission for it, and use a hidden API. The problem Such a solution won't work anymore, but instead, Google provides an official API that's less granular: queryStatsForPackage , which returns StorageStats object. However, I can't find any information of how to use it. As opposed to the hidden API, which only required the package name of the app, this one also requires "String volumeUuid" and "UserHandle user". The questions How do I provide those parameters? What do they mean? Is each of the volumeUuid refer

Android 8's battery consumption improvements are nice to the user but I am a bit afraid if my service will work as expected. First of all: Thank you for any suggestions but I cannot just schedule my service. I want to make a OK Google -like keyword listener running in the background all the time. It will be based on the open source pocketsphinx-android library. I know that this will consume much battery power and I will inform the user about this. Can we create a permanent background service on android 8+ ? I need to target android 8 in gradle because I was expecting some bugs with older

I have a foreground service that needs to get a single location update. It is started by a specific broadcast, and upon starting it simply does a request on our backend. When it receives another broadcast, it requests a location update (once), does another backend request and then stops itself.

This works well on Lollipop and Marshmallow, both when the phone is awake or in Doze mode. But for some reason, on Android O the service never gets location updates
