Location listener works from a Service but not an IntentService

由 佐手、 提交于 2020-01-01 00:34:06
问题 I have an app where I am trying to periodically get user location and send to server. I have a service attached to an AlarmManager which executes every minute (for testing). The service finds the user location correctly and logs out the GPS co-ords. Once there is a GPS lock I cancel the location request and stop the service. When I ask for location updates, I start a Handler that executes 20 seconds later, this Handler removes the location update and stops the Service in case no lock is

How to Keep the CPU of android phone always awake?

问题 I have been stuck on it for days. I need to execute a function every minute. This function is making a POST call from the App to the Server and is transferring the location of the user per minute. The location coordinates are transferred for few hours, however, after few hours the transfer of location coordinates to the Server stops on its own. I am making use of WakefulBroadcastReceiver and IntentService to make sure that the CPU stays awake. I am also making use of Alarm to make sure that

Design pattern for alternate action if app in foreground?

问题 I'm building an action which utilizes Google Cloud Messaging for receiving push notifications. This involves a couple notable components, namely: A WakefulBroadcastReceiver to receive the message from GCM. An IntentService to be notified when a GCM event is received. As I'm sure is the case for many applications, I'd like to take a different approach for when the application has an activity in the foreground vs. when the application does not have an application in the foreground. I'd like to

Is there any reason to continue using IntentService for handling GCM messages?

由 瘦欲@ 提交于 2019-12-29 07:44:51
问题 As you know, recently Google changed their GCM documentation, and they claim that an IntentService is no longer required for handling arriving GCM messages. All the handling can be done in the BroadcastReceiver . When trying to figure out if there is any good reason to continue using the IntentService , I came across this quote: A Service (typically an IntentService) to which the WakefulBroadcastReceiver passes off the work of handling the GCM message, while ensuring that the device does not

IntentService源码分析

我们带着问题来看源码！ 一. IntentService如何单独开启一个新的工作线程？ @Override public void onCreate ( ) { // TODO: It would be nice to have an option to hold a partial wakelock // during processing, and to have a static startService(Context, Intent) // method that would launch the service & hand off a wakelock. super . onCreate ( ) ; // 1 HandlerThread thread = new HandlerThread ( "IntentService[" + mName + "]" ) ; thread . start ( ) ; // 2 mServiceLooper = thread . getLooper ( ) ; //3 mServiceHandler = new ServiceHandler ( mServiceLooper ) ; } 1.实例化HandlerThread新建线程并启动，这里注意HandlerThread 继承自Thread，内部封装了Looper； 2.

Fetching user location in background and uploading it to web server (trying to avoid using Service)

由 空扰寡人 提交于 2019-12-25 00:34:04
问题 My application is based on Google Map and Location which includes client-server communications. Apart from all that, periodically I want to update the user location to web server. I gave thought myself and ended up with below two scenarios, First One : I use Service class to fetch user location periodically (considering 2-3 hours once) and update to server. Ideally I want to avoid this! Because just to upload user location its not good to run the service all the time is what I feel. Second

问题 I'm developing an app in which data saved into database when there is no covered area of mobile signals. When service came back it will fetch all data from database and upload on server.

问题 I'm new to android and I am creating a MAC spoofing app. I have created an IntentService to spoof the MAC address in the app every 5 seconds and it is working fine. Then I created a BaseActivity which all of my activities extend from, this is so I can detect when the app goes in the background or not, this is also working fine. I already have it so when the app is in the background, the MAC address no longer changes and goes back to its original, but instead of this I want to just stop the
