java - Execute code in the same method after Thread.join() executes -

i have problem, join method, kill thread, not executing rest of method, started in thread. here code example:

private static thread thread;  public static void addmessage(final string s) {     thread = new thread() {         @override         public void run() {             string data = message.send(s);             addmessagetocontainer(data);         }     };     thread.start(); }  public static void addmessagetocontainer(string data) {     //do stuff data     try {         thread.join();     } catch (interruptedexception e) {         e.printstacktrace();     }     //this code here not executed. } 

so normally, of course can execute code before call join function. have load after thread execution webview content. when remove join, give me following error message:

java.lang.runtimeexception: java.lang.throwable: webview method called on thread 'thread-9072'. webview methods must called on same thread. (expected looper looper (main, tid 1) {5ac9b39} called on null, fyi main looper looper (main, tid 1) {5ac9b39}) 

so can load content after thread has executed?

join doesn't kill thread. join waits until thread kills itself. code executed- @ time in future, when thread decides done. calling wait on thread thread cause deadlock , never anything, yet never die. in case above you're calling thread itself, hang forever.

there no way kill thread directly, because impossible safely. way kill thread outside interrupt it, , let thread check if isinterrupted() every , if kill itself. way kill thread inside return runnable's run method.

your webview error totally unrelated. can touch views on main thread. don't webview on thread.
