Listen to location access disable/enable in settings

由 两盒软妹~` 提交于 2019-12-09 17:12:13
问题 In Android OS, in " Settings " --> " Location services ", there is a toggle button named " Access to my location " which can be used to disable & enable location info access from apps. Currently, I am developing a location service application. I am wondering, how can I listen to this setting in my Android project? Is there any broadcast receiver I can use to know right away when user disable or enable " Access to my location " ? If there isn't any broadcast receiver for it, how can I listen

How to release the microphone resource when another Android app needs it?

由 一个人想着一个人 提交于 2019-12-09 09:20:37
问题 I have implemented an Android background service (based in Pocket Sphinx) that continuously listens, detects and spots certain keywords when the phone's screen is on, and then reacts accordingly (for a domotic project). However, my app should always have a lower priority and I want it to release the microphone's resources when any other app needs to use it. Is there any system intent or system broadcast that I can receive when an app -wants- to use the microphone (so that my service can

问题 I'm on Android 2.3.7 and I'm trying to write a BroadcastReceiver that will get called when the user turns GPS on/off (ie: by tapping on the "use GPS satellites" in the options. What I've done so far is this: 1) Created the following broadcastReceiver: public class GPSStatusBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context arg0, Intent arg1) { Toast.makeText(arg0, "Broadcast received!", Toast.LENGTH_SHORT).show(); } } 2)Added this to the android manifest,

问题 I have an IntentService which starts on boot and stays running in the background. There is no launcher Activity, the IntentService is called by a broadcast receiver. It works on 2.3.4 and 4.0.4 devices but not on 4.2.2. Maybe my broadcast receiver isn't being triggered on the device?

SMS_RECEIVED onReceive android 2.3.5 not triggering

由 99封情书 提交于 2019-12-09 06:57:26
I've been puzzling over this one recently, prior to 2.3.5 this seems to work fine (on my colleagues devices). However on mine it now never triggers. I've stripped the code right back and made a very simple test application to see what's going on. Basically the onReceive code doesn't ever appear to trigger, even though adb/logcat does seem to show the register of the BroadcastReveiver does take place. Here's the simple code I've gone for: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.broadcasttech.testsmsreceive" android
