Signalling a root C++ executabke from a non-privileged Java Android app

阅读更多关于 Signalling a root C++ executabke from a non-privileged Java Android app

问题 I am amending an Android C++ system executable (healthd), which runs as root. I want the amended healthd to be able to receive some form of signal from an unprivileged Android Java app. A few hundred ms of latency is fine, as is polling from healthd, rather than an actual "event". I only need to send an indication that something has happened - there's no requirement to transport data. What's the simplest form of communication I can use? 来源： https://stackoverflow.com/questions/57199825

阅读更多关于 Android: Implement a custom ConnectionService which uses built-in telephony stack

问题 I'm trying to implement a custom ConnectionService in my custom telephony-app. According to the documentation I need to select my registered PhoneAccount as default in the Phones settings menu. However when I'm registering a PhoneAccount to use the native telephony stack the PhoneAccount does not seem to show up for use. Let me show you what I got working so far.

I noticed this on an app where I haven't modified anything in the code, but simply updated the OS on the device and yet the spinners have different sizes. Situation: I have 2 spinners one next to the other in a RelativeLayout (mind the rest of the components, I added everything so you can see this part of the

Upgrading app in background using Device Policy Controller

问题 I have a working DPC app which is the Device Owner. I have tried this on two different Android 6.0.1 devices to rule out any device/manufacturer issues. I used adb shell dpm set-device-owner com.example.dpc/.DpcDeviceAdminReceiver to make my DPC-app the owner. After making it the owner it can correctly grant COSU permissions to another app, which convinces me that this has worked. The command returned the response: Success: Device owner set to package com.example.dpc Active admin set to
