android-8.0-oreo

In my Android application I'm using the following code snippet: @RequiresApi(api = Build.VERSION_CODES.O) private void turnOnHotspot(){ WifiManager manager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE); manager.startLocalOnlyHotspot(new WifiManager.LocalOnlyHotspotCallback(){ @Override public void onStarted(WifiManager.LocalOnlyHotspotReservation reservation) { super.onStarted(reservation); Log.d(TAG, "Wifi Hotspot is on now"); } @Override public void onStopped() { super.onStopped(); Log.d(TAG, "onStopped: "); } @Override public void onFailed(int reason) {

This question already has an answer here: NotificationCompat.Builder deprecated in Android O 9 answers Notification.Builder(context) has been deprecated recently with the venue of Notification Channels in Android O. PROBLEM: After using Notification.Builder(context, StringID) instead of Notification.Builder(context) I did receive a notification to my Android O device. However, after trying that on an Android 23 (M), I did not receive a notification. I debugged my code and it just stopped executing once the debugger hit the line post Notification.Builder(context, StringID) on Android 23 (M).

I am trying to scan for beacons using startScan(filters, settings, callbackIntent) . I have an implementation that works fine for Sony Xperia XZ, and Nexus 5X. The only other device with Android O I have available is a Samsung Galaxy S8, and what works for the other devices produce nothing on the Samsung. (The bluetooth scan is really imbedded in a library module, but even when creating a dummy app the samsung fails, so I'll use that in this example). I have removed the filter and the settings used for startScan since the scan doesn't work without them anyway and these are optional.

I have created an Android app with its own launcher icon. It worked well with Nougat. But with Oreo, my icon is replaced by the default Android icon. I have defined ic_launcher.png and ic_launcher_round.png in the mipmap resources for several densities. My manifest contains the following line: android:roundIcon="@mipmap/ic_launcher_round" What should I do to make my own icon appear on Oreo ? For API 26+ default Android application template defines another icon resource folder mipmap-anydpi-v26 That folder (usually) contains two xml files ic_launcher and ic_launcher_round that match icon

I'm really confused. I have just noticed that starting from Android 8 all system calls like /proc/stat will be disabled. Ok, but what is work around to get CPU Usage in Android 8? No system calls at all. Is there some API that I'm not familiar with? I really hope that there is solution which I can't see now. No, all of /proc/stat has been disabled for non-System apps, as a side-channel.
