I create a new thread, and y need to interrupt, I use the thread.interrup(), but when I throw request thread interrupt is not working on ios, works fine on simulator or in Android device.
I Attach code to try it.
My temporal solution is use a Flag to break while, but I want to use the InterruptedException
package com.kandy.forms;
import com.codename1.io.Log;
import com.codename1.ui.Button;
import com.codename1.ui.Dialog;
import com.codename1.ui.Display;
import com.codename1.ui.Form;
import com.codename1.ui.layouts.BoxLayout;
public class Interrup extends Form {
private Form previous;
private Thread thread = null;
public Interrup() {
setLayout(new BoxLayout(BoxLayout.Y_AXIS));
Button newThread = new Button ("Start Thread");
newThread.addActionListener((e) -> {
thread = new Thread(new Runnable() {
#Override
public void run() {
while (true) {
try {
Thread.sleep(1000);
Log.p("thread working");
} catch (InterruptedException ie) {
Dialog.show("Message", "Interruption received", "Ok", null);
break;
}
}
}
});
//thread start
thread.start();
});
Button interruptTreath = new Button ("Interrupt");
interruptTreath.addActionListener((e) -> {
Log.p("Interrupt Sended");
thread.interrupt();
});
add(newThread);
add(interruptTreath);
}
public void show() {
previous = Display.getInstance().getCurrent();
super.show();
}
public void goBack(){
previous.showBack();
}
}
This isn't supported on iOS. Neither is stop etc. as those are pretty hard to get working consistently across platforms. This is especially true for iOS and the thread implementation in the JavaScript port.

I'm trying to run a simple Hello World program with CodenameOne in Java. I'm trying to add a button to the app. I get two compiler errors, both of them:
java: cannot find symbol
symbol: class Button
Here is the code:
//ORIGIONAL CODE
package CodenameOneHelloWorld;
import static com.codename1.ui.CN.*;

import com.codename1.ui.Toolbar;
import java.io.IOException;
import com.codename1.ui.layouts.BoxLayout;
import com.codename1.io.NetworkEvent;
/**
* This file was generated by Codename One for the purpose
* of building native mobile applications using Java.
*/
public class MyApplication {
private Form current;
private Resources theme;
public void init(Object context) {
// use two network threads instead of one
updateNetworkThreadCount(2);
theme = UIManager.initFirstTheme("/theme");
// Enable Toolbar on all Forms by default
Toolbar.setGlobalToolbar(true);
// Pro only feature
Log.bindCrashProtection(true);
addNetworkErrorListener(err -> {
// prevent the event from propagating
err.consume();
if(err.getError() != null) {
Log.e(err.getError());
}
Log.sendLogAsync();
Dialog.show("Connection Error", "There was a networking error in the connection to " + err.getConnectionRequest().getUrl(), "OK", null);
});
}
public void start() {
if(current != null){
current.show();
return;
}
Form hi = new Form("Hi World", BoxLayout.y());
hi.add(new Label("Hi World"));
Button b = new Button("Show Dialog"); // LINE HAND-TYPED ACCORDING TO TUTORIAL
hi.add(b); // LINE HAND-TYPED ACCORDING TO TUTORIAL
b.addActionListener((e) -> Dialog.show("Dialog Title", "Hi", "OK", null)); // LINE HAND-TYPED ACCORDING TO TUTORIAL
hi.show();
}
public void stop() {
current = getCurrentForm();
if(current instanceof Dialog) {
((Dialog)current).dispose();
current = getCurrentForm();
}
}
public void destroy() {
}
}
After following the compiler's directions, I have the new following code:
// CODE MODIFIED BY SUGGESTION FROM COMPILER
package CodenameOneHelloWorld;
import static com.codename1.ui.CN.*;

public class MyApplication {

private Resources theme;
public void init(Object context) {
// use two network threads instead of one
updateNetworkThreadCount(2);
theme = UIManager.initFirstTheme("/theme");
// Enable Toolbar on all Forms by default

// Pro only feature
Log.bindCrashProtection(true);
addNetworkErrorListener(err -> {
// prevent the event from propagating
err.consume();
if(err.getError() != null) {
Log.e(err.getError());
}
Log.sendLogAsync();
Dialog.show("Connection Error", "There was a networking error in the connection to " + err.getConnectionRequest().getUrl(), "OK", null);
});
}
public void start() {
if(current != null){
current.show();
return;
}
Form hi = new Form("Hi World", BoxLayout.y());
hi.add(new Label("Hi World"));
Button b = new Button("Show Dialog");
hi.add(String.valueOf(b)); // CHANGED LINE AS SUGGESTED BY COMPILER
b.addActionListener((e) -> Dialog.show("Dialog Title", "Hi", "OK", null));
hi.show();
}
public void stop() {
current = getCurrentForm();
if(current instanceof Dialog) {
((Dialog)current).dispose();
current = getCurrentForm();
}
}
public void destroy() {
}
}
The new code compiles clean, but when run in the simulator, the app displays an error message instead of the button.
Does anybody have any idea on how to get the button to display properly in the Hello World app?
AWT won't work here. The IDE offers more than one option when you try to import and the other option should be import com.codename1.ui.Button;. You can see the full list of supported classes in the JavaDocs here: https://www.codenameone.com/javadoc/
Until today, my code has been working great. However, I've just started getting NPE when using the Crisp CN1lib. It turns out that BrowserComponent.setProperty() is the culprit. Here is my stacktrace
java.lang.NullPointerException
at com.codename1.impl.javase.JavaSEPort.setBrowserProperty(JavaSEPort.java:11340)
at com.codename1.ui.BrowserComponent.setProperty(BrowserComponent.java:607)
Looks like the JavaSEPort.setBrowserProperty() is causing it. Github shows the code was edited 2 days ago so maybe something broke.
My code is pretty basic:
import static com.codename1.ui.CN.*;
import com.codename1.ui.Form;
import com.codename1.ui.Dialog;
import com.codename1.ui.plaf.UIManager;
import com.codename1.ui.util.Resources;
import com.codename1.io.Log;
import com.codename1.ui.BrowserComponent;
import com.codename1.ui.Toolbar;
import com.codename1.ui.events.ActionEvent;
import com.codename1.ui.events.ActionListener;
import com.codename1.ui.layouts.BorderLayout;
/**

public class MyApplication {
private Form current;

addNetworkErrorListener(err -> {

err.consume();
if(err.getError() != null) {
Log.e(err.getError());
}
Log.sendLogAsync();
Dialog.show("Connection Error", "There was a networking error in the connection to " + err.getConnectionRequest().getUrl(), "OK", null);
});
}
public void start() {
if(current != null){
current.show();
return;
}
BrowserComponent browser = new BrowserComponent();
browser.addWebEventListener(BrowserComponent.onLoad, new ActionListener() {
#Override
public void actionPerformed(ActionEvent evt) {
}
});
browser.setProperty("UseWideViewPort", true);
browser.setProperty("LoadWithOverviewMode", true);
browser.setProperty("DatabaseEnabled", true);
browser.setProperty("BuiltInZoomControls", true);
browser.setProperty("DisplayZoomControls", false);
browser.setProperty("WebContentsDebuggingEnabled", true);
browser.setFireCallbacksOnEdt(true);
browser.setURL("https://www.instagram.com/brianabette/");
Form hi = new Form("Hi World", new BorderLayout());
hi.add(BorderLayout.CENTER, browser);
hi.show();
}
public void stop() {
current = getCurrentForm();
if(current instanceof Dialog) {
((Dialog)current).dispose();
current = getCurrentForm();
}
}
public void destroy() {

}
Any pointers? Bug maybe?
We just made some performance improvements to BrowserComponent. Looks like we missed a spot here, so there is a regression. It is already fixed in Git and will be included in the next update next Friday.
No code is firing in runOnUiThread in the native implementation. Codes before runOnUiThread does fire. I am sure I am not doing something right.
I created the CodenameOne Library like this
package com.uithread.test;
import com.codename1.system.NativeInterface;
public interface UIThreadNative extends NativeInterface {
public void runNativeCode();
}
package com.uithread.test;
import com.codename1.system.NativeLookup;
import com.codename1.ui.Dialog;
public class UIThreadManager {
private static UIThreadNative uithreadNative;
public UIThreadManager() {
if (uithreadNative == null) {
uithreadNative = (UIThreadNative) NativeLookup.create(UIThreadNative.class);
if (uithreadNative == null) {
Dialog.show("Null implementation", " UIThread is not implemented yet in this platform.", "Ok", null);
throw new RuntimeException("UIThread is not implemented yet in this platform.");
}
}
if (!uithreadNative.isSupported()) {
Dialog.show("Unsupported", " UIThread is not supported in this platform.", "Ok", null);
throw new RuntimeException("UIThread is not supported in this platform.");
}
}
public void runNativeCode() {
uithreadNative.runNativeCode();
}
}
Native implementation for android
package com.uithread.test;
import android.content.Context;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import com.codename1.impl.android.*;
import com.codename1.ui.Dialog;
public class UIThreadNativeImpl {
private static Context context() {
return com.codename1.impl.android.AndroidNativeUtil.getActivity().getApplicationContext();
}
private static Activity activity() {
return com.codename1.impl.android.AndroidNativeUtil.getActivity();
}
public void runNativeCode() {
final Activity convenientActivity = activity();//AndroidNativeUtil.getActivity();
final CodenameOneActivity codenameoneActivity = (CodenameOneActivity) AndroidNativeUtil.getActivity();
final android.app.Activity app = (Activity) AndroidNativeUtil.getActivity();
Dialog.show("Activity", convenientActivity + " convenientActivity", "Ok", null);
Dialog.show("Activity", codenameoneActivity + " codenameoneActivity", "Ok", null);
Dialog.show("Activity", app + " App", "Ok", null);
convenientActivity.runOnUiThread(new Runnable() {
public void run() {
Dialog.show("In run", "Run started", "Ok", null);
}
});
}
public boolean isSupported() {
return true;
}
}
In Statemachine I run this in code on a button click.
#Override
protected void onMain_ButtonAction(Component c, ActionEvent event) {
UIThreadManager uIThreadManager = new UIThreadManager();
uIThreadManager.runNativeCode();
}
As I said earlier. The codes before runOnUiThread work but the codes in runOnUiThread does not work. The dialogs in the runNativeCode in the native implementation were for checking the activity in different flavors which shows correctly that the different flavors are the same.
Thanks.
The native UI thread is totally different from our EDT so showing a Codename One dialog from that thread would be a huge EDT violation that can cause a serious crash!
Since our dialog blocks safely you would be effectively blocking the entire application and crashing it.
We use this line which is pretty much equivalent to what you wrote quite a bit in Codename One and in libraries e.g. here:
AndroidNativeUtil.getActivity().runOnUiThread(new Runnable() { ... });
iam using mediarecorder to record video in android application. I will start and stop recording video multiple times i will start recording on Action_down and stop on Action_up this is going on well and iam able to store and play video file in mobile .
my problem is that since i have to start and stop recording video multiple times i can't use single output file becuase everytime it will get over written so everytime iam passing new file name and iam appending that to one outputfile everytime.iam getting every individual file and final outputfile in mobile but final file is having only what i have recorded for the first time because from second tab if see the file.mp4.length()is zero why it is ? anyone please try to help me. my code is as follows

In order to combine multiple video files you should use mp4parser library : https://mp4parser.googlecode.com/svn/trunk/examples/src/main/java/com/googlecode/mp4parser/AppendExample.java
I havefollowed the example at
http://www.qaautomation.net/?p=263
package net.qaautomation.examples;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.Wait;
import org.openqa.selenium.support.ui.WebDriverWait;
/**

*/
public class GoogleSearch {
static WebDriver driver;
static Wait<WebDriver> wait;
public static void main(String[] args) {
driver = new FirefoxDriver();
wait = new WebDriverWait(driver, 30);
driver.get("http://www.google.com/");
boolean result;
try {
result = firstPageContainsQAANet();
} catch(Exception e) {
e.printStackTrace();
result = false;
} finally {
driver.close();
}
System.out.println("Test " + (result? "passed." : "failed."));
if (!result) {
System.exit(1);
}
}
private static boolean firstPageContainsQAANet() {
//type search query
driver.findElement(By.name("q")).sendKeys("qa automation\n");
// click search
driver.findElement(By.name("btnG")).click();
// Wait for search to complete
wait.until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver webDriver) {
System.out.println("Searching ...");
return webDriver.findElement(By.id("resultStats")) != null;
}
});
// Look for QAAutomation.net in the results
return driver.findElement(By.tagName("body")).getText().contains("qaautomation.net");
}
}
to the letter but when I run it I get the error

any ideas on what might be wrong? In fact several other examples I tried all give me a similar NoSuchMethod Error. EG http://thomassundberg.wordpress.com/2011/10/18/testing-a-web-application-with-selenium-2/
If you have any simple working Selenium2 example I would be grateful for a link. Thnx
If you're looking to get started with Selenium webdriver I'd suggest reading through the documentation on seleniumhq.org and perhaps try the example on the following page it's a little bit more simplified.
http://seleniumhq.org/docs/03_webdriver.jsp
I would also suggest using eclipse and staying away from maven and ant until you get a good grasp on webdriver, that's assuming you're new to these applications.
