问题 I'm currently trying to test Google's App Invites, but I'm having a tough time testing the INSTALL_REFERRER broadcast feature without putting an app up on the Play Store App Invite broadcast intents require a bundle extra named "com.google.android.gms.appinvite.REFERRAL_BUNDLE" and it's checked in AppInviteReferral like so: public static boolean hasReferral(Intent referralIntent) { return referralIntent != null && referralIntent.getBundleExtra("com.google.android.gms.appinvite.REFERRAL_BUNDLE

Google Awareness Api events while app isn't running

问题 I would like either a BroadcastReceiver or IntentService (depending on how long my eventual processing takes) to start when a Google Awareness API "fence" fires. For example, perhaps I want to know how many times I activate a set of beacon fences over the course of the day (assuming I keep my phone with me). All the examples I've found show registering broadcast receivers in code, but my understanding is that I would need to register a broadcast receiver in the manifest in order for the OS to

问题 I am part way through writing a media player app for Android. It's all going really well so far, however I am now reaching the difficult stage! I have two questions. Do i need to implement a service activity? As I understand it, this is required to allow the app to continue working in the background. However, mine is working fine while I move to other programs on the tablet, and returns to the app without problems. Can someone please explain what the advantages are of services? Secondly, I

Android开机自动运行APP——BroadcastReceiver

由 徘徊边缘 提交于 2019-12-09 17:12:20
前言： 有些时候，应用需要在开机时就自动运行，例如某个自动从网上更新内容的后台service。怎样实现开机自动运行的应用？在撰写本文时，联想到高焕堂先生以“Don't call me, I'll call you back!”总结Android框架，真是说到点子上了。理解这句话的含义，许多有关Android平台上实现某种功能的问题，都能迎刃而解。 使用场景： 手机开机后，自动运行程序。 {只是最近本人在做万达大歌星点餐系统，需要用到系统启动直接启动App避免服务员玩别的app才研究的，以下分享是本人参考网络，亲自尝试成功的代码，贴出来与大家分享，希望能帮助更多的人！不懂的可以问我哦。QQ：11745405 } 背景知识： 当Android启动时，会发出一个系统广播，内容为ACTION_BOOT_COMPLETED，它的字符串常量表示为android.intent.action.BOOT_COMPLETED。只要在程序中“捕捉”到这个消息，再启动之即可。记住，Android框架说：Don't call me, I'll call you back。我们要做的是等到接收这个消息，而实现的手段就是实现一个BroadcastReceiver。 代码解析： 1、界面 MainActivity .java package com.example; import android.app
