    android multithreading android-ndk jni
    My application makes multiple calls from native threads to java, i am seeing the memory usage of the application slowly creeping up. It looks like the calls to attach and detach cause JAVA to leak a thread. I can see this by running DDMS memory analyser.I have written a really simple test app that demonstrates my issue, start test is called from JAVA and kicks off the thread. It doesn’t do anything other then attach and then detach the worker thread.void detachFromThread(JavaVM *vm) {if(vm != NU

    android toast android-xml
    I know that I could do all of this easily with a custom toast layout, but in creating a custom layout, I would no longer be using the system’s default toast view.Example: Toasts of course look different in Android 2.2 vs Android 4.0. If I create a custom view for my toast, then it will look the exact same in both versions, but what I want is for it to retain its… “Androidiness” for lack of a better word. Basically, does anyone know of a default toast XML layout? Is that even possible?

    php android http-post httpclient connectionexception
    i am using HttpClient to send POST requests from Android to php server. Connection was working fine, but in last few days i get response “Connection refused from server”. But strange is that connection is not refused every time…Connection is not so stable as i require… Many times i get exception connection refused. PHP Server is standard php Web hosting… I suppose that the problem will be on server side, because connection can be established, but due to “connection refused” is very unstabl

    php html mysql http-post
    My $_POST name is : $_POST[p_new_1], $_POST[p_new_2], $_POST[p_new_3], etc. depends on the value of $_POST[number] (above is $_POST[number] equal to 4). Now I need to add that value to table by :mysqli_query($con,”INSERT INTO `tablename` (`Name`) VALUES (‘$_POST[p_new_1]’)”);But it only work if I know that $_POST[number]=2; sometimes $_POST[number] has no value or value greater than 2, in general case it should be:if($_POST[number]!=NULL) for ($i = 1; $i < $_POST[number]; $i++) {mysqli_query

    http post get http-post http-get
    Simply put, I have a website where you can sign up as a user and add data. Currently it only makes sense to add specific data once, so an addition should be idempotent, but theoretically you could add the same data multiple times. I won’t get into that here.According to RFC 2616, GET requests should be idempotent (really nullipotent). I want users to be able to do something like visithttp://example.com/<username>/add/?data=1And this would add that data. It would make sense to have a PU

    javascript html5 setinterval keydown
    So I am at the very beginning stages of creating my first platform style game in html5.So far I have only implemented left and right movement and no ‘gravity’ or collision detection is at play.However, I’ve already hit an issue.If you go left or right for a short period of time the ‘character’ acts as intended (I use character loosely as it’s the map that is actually moving). If, however, you hold the key down the map moves too fast.I figure the issue is that the keydown event listener is listen
