问题 I get this warning message and since I see this message I also started to see the Google Play Services isnt responding popup and it closes my application after some time. I have review similar questions but could not find out the reason. Following is a sample of my handler thread usage. I do not know what to do to avoid this problem. @Override public void find(Func1<RealmQuery<Artist>, RealmQuery<Artist>> query, Action1<Result<List<Artist>>> onResult) { if (query != null) { handlerThread =

问题 This bug baffled me for hours. I am getting the NullPointerException . The problem is this error is not consistent. It happens when I launch the app, but only occasionally. So I am not sure what is causing it. I apologize for the verbose question with the error log, but I could not find another way of asking. The error log is as follows: FATAL EXCEPTION: main Process: com.myproject.android, PID: 22175 java.lang.NullPointerException at com.myproject.android.ImageDownloaderThread.queueImage

Where to quit the handler thread that used for realm operations in Android?

问题 I have an android application that I do many realm operations . I wanted to do those stuff on background and to do that I have used handler threads . I also used handler threads in some of my activities and service classes and I quit() those handler threads inside of onTerminate() or onDestroy() methods. However I do not know where should I quit the handler thread when I use it inside if a non-activity classes since they do not have onDestroy() methods. I have commented the handlerThread.quit

问题 I want to set up a HandlerThread from the GUI thread. Then some time later, when a button is clicked on the GUI, it runs callHello(), which then send a message to a HelloLogger object residing on the non-GUI thread which asynchronously logs "Hello World". I have tried a number of things, some block indefinitely, some never receive the message, etc etc. The code below is more or less as close as I have got, please could someone modify it to work? public class HandlerThreadExample { private

Why use HandlerThread in Android

由 喜欢而已 提交于 2019-11-28 20:44:17
In android , Handler can be used to post / handle message, if I don't use a HandlerThread (pass its Looper to Handler), does that mean in this case Handler use MainThread (UI Thread) 's Looper ? What result will get if Handler uses MainThread's Looper ? May cause mainThread blocked ? You would use HandlerThread in case that you want to perform background tasks one at a time and you want that those tasks will run at the order of execution. For example if you want to make several network background operations one by one. Yes, the HandlerThread has it's own looper and handlers could be created
