Android - Bluetooth discovery doesn't find any device

由 和自甴很熟 提交于 2019-12-20 10:17:47
问题 I'm currently working on a little app to get started with the services that the Bluetooth Android API can provide. Edit -> Answer: It seems that the issue was due to the specific Nexus 5 devices. Seems like their bluetooth receiver doesn't work well. Solution below should work for other devices Remark: I’ve read the documentation here: http://developer.android.com/guide/topics/connectivity/bluetooth.html as well as the following source code of this tutorial http://www.londatiga.net/it

Android 5.0.2 - SMS Broadcast Receiver - can not get it working

由 ぐ巨炮叔叔 提交于 2019-12-18 07:06:37
问题 I am testing on Xiaomi Redmi Note 3 and what I need is very simple: * Register broadcast receiver for incoming text messages * Once message comes in, just read it It looks like I can not get receiver register no matter what I try. From the google docs, since 4.4 there should be no way for any app to swallow the event and every app listening should get a chance to get the event. I have tried all kind of combinations and googled pretty much everything. Could it be the Xiaomi phone issue? Here

由 主宰稳场 提交于 2019-12-17 18:17:14

Detect day change event in broadcast receiver in android

由 北城余情 提交于 2019-12-06 08:44:37
问题 I want to implement a feature in android app which execute a particular code when ever there is a date change(at 00:00AM) even when my app is not running. 回答1: I might be late answering this question, but I personally faced the same problem. For day change, you can simply use a broadcast receiver with action "android.intent.action.DATE_CHANGED", and it will trigger whenever the date is changed (either implicitly or explicitly by user). I hope this will help someone who gets to here through

Android Intent Action 大全

1.Intent的用法： （1） Action跳转 1、 使用Action跳转，当程序AndroidManifest.xml中某一个 Activity的IntentFilter定义了包含Action，如果恰好与目标Action匹配，且其IntentFilter中没有定义其它的Type或Category过滤条件，那么就正好匹配了。如果手机中有两个以上的Action程序匹配，那么就会弹出一个对话可框来提示说明。例如打开一个网址，弹出可选对话框： Action 的值在Android中有很多预定义，如果想直接转到自己定义的Intent接收者，可以在接收者的IntentFilter 中加入一个自定义的Action值（同时要设定 Category值为"android.intent.category.DEFAULT"），在你的Intent中设定该值为Intent的 Action就直接能跳转到你自己的Intent接收者中，因为这个Action在系统中是唯一的。 2、 data/type，可以用Uri 来做为data，比如Uri uri = Uri.parse(“ http://blog.csdn.net/sunboy_2050 ” ); Intent i = new Intent(Intent.ACTION_VIEW, uri); 手机的Intent分发过程中，会根据“ http://blog
