Bad notification for startForeground

On Huawei P20 Pro With Android 8.1.0 I had to disable startForeground in order to let nordic dfu updater works, otherwise app crashes with this error:

                                                                             at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2095)
                                                                             at android.os.Handler.dispatchMessage(Handler.java:109)

                                                                             at android.app.ActivityThread.main(ActivityThread.java:7367)
                                                                             at java.lang.reflect.Method.invoke(Native Method)
                                                                             at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:469)
                                                                             at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:963)

So i replaced this statement

final DfuServiceInitiator starter = new DfuServiceInitiator(mSelectedDevice.getAddress())
                .setDeviceName(mSelectedDevice.getName())
                .setKeepBond(keepBond);

with

        final DfuServiceInitiator starter = new DfuServiceInitiator(mSelectedDevice.getAddress())
                .setForeground(false)                // Foreground doesn't work correctly for android 8.1
                // See https://stackoverflow.com/questions/47531742/startforeground-fail-after-upgrade-to-android-8-1
                .setDeviceName(mSelectedDevice.getName())
                .setKeepBond(keepBond);

Instead I think that startForeground should be implemented according to this issue notified on stackoverflow: https://stackoverflow.com/questions/47531742/startforeground-fail-after-upgrade-to-android-8-1

I have the same issue on my Android Things Board and solved by starter.setForeground(false); starter.setDisableNotification(true); Anyway I don’t need them.

@1ALo

what is starter in your code ?

starter is the DfuServiceInitiator, I guess.
