bootcompleted

问题 I want to listen to APN Changes in my Android App. Therefore I start a Service on android.intent.action.BOOT_COMPLETED . This Service starts a ContentObserver which listens to changes to content://telephony/carriers/preferapn . I tested this setup on a few different devices (e.g. LG Spirit with Android 5.0, Samsung A3 with 6.0, Emulator Nexus5 with 7.0 and Huawei P9 Lite with 7.0) On the Huawei phone onCreate of my Service is not called. My other approach with android.intent.action.ANY_DATA

问题 I've an app that has a receiver of android.intent.action.BOOT_COMPLETED and start a private VPN. But when I receive a android.intent.action.BOOT_COMPLETED the network isn't ready yet.

问题 I am trying to 'emulate' a reboot (or anything else with the adb shell am ) and am unable to figure out how to reference my component. Then again, maybe I don't even understand what is meant by a component. Below I first include a few example commands that don't work, then my manifest. Note that StartupReceiver is successfully called when the 'phone' boots. I just want to re-trigger it without a full reboot. Failed ADB commands: $ ./adb shell am broadcast -a android.intent.action.BOOT

问题 I can't start a service as soon as device boots.

问题 I am currently working on a application which includes Boot_Completed Broadcast receiver concept. I have tested this app in my Motorola Moto G Phone. The app runs fine and shows the Toast message. But when I test this app in XIAOMI Redmi 1S phone it doesn't show the Toast message. I have already seen many questions similar to my issue (like these - Question 1, Question 2, etc.) ...
