Robotium test case not Running at all - robotium

Am a day old to Robotium. Hence trying to run some apps on Robotium.
I have done a simple calci app and am trying to run it using Robotium.
But the Robotium app is not responding at all. Neither the tests are being done.
I have included the permissions in Manifest file and all. But still the Program never runs.
My Source Code for Robotium Test is like this:
package com.example.demo.project.test;
import android.test.ActivityInstrumentationTestCase2;
import android.widget.EditText;
import android.widget.TextView;
import com.example.demo.project.MainActivity;
import com.example.demo.project.R;
import com.jayway.android.robotium.solo.Solo;
public class SampleQA extends ActivityInstrumentationTestCase2<MainActivity> {
public SampleQA(Class<MainActivity> activityClass) {
super(activityClass);
// TODO Auto-generated constructor stub
}
private Solo solo;
/*public TestMain()
{
super(MainActivity.class);
}*/
#Override
protected void setUp() throws Exception {
super.setUp();
solo = new Solo(getInstrumentation(), getActivity());
}
public void testDisplayBlackBox() {
//Enter 10 in first edit-field
solo.enterText(0, "10");
//Enter 20 in first edit-field
solo.enterText(1, "20");
//Click on Multiply button
solo.clickOnButton("Multiply");
//Verify that resultant of 10 x 20
assertTrue(solo.searchText("200"));
}
public void testDisplayWhiteBox() {
//Defining our own values to multiply
float firstNumber = 10;
float secondNumber = 20;
float resutl = firstNumber * secondNumber ;
//Access First value (edit-filed) and putting firstNumber value in it
EditText FirsteditText = (EditText) solo.getView(R.id.EditText01);
solo.enterText(FirsteditText, String.valueOf(firstNumber));
//Access Second value (edit-filed) and putting SecondNumber value in it
EditText SecondeditText = (EditText) solo.getView(R.id.EditText02);
solo.enterText(SecondeditText, String.valueOf(secondNumber));
//Click on Multiply button
solo.clickOnButton("Multiply");
assertTrue(solo.searchText(String.valueOf(resutl)));
TextView outputField = (TextView) solo.getView(R.id.TextView01);
//Assert to verify result with visible value
assertEquals(String.valueOf(resutl), outputField.getText().toString());
}
#Override
protected void tearDown() throws Exception{
try {
solo.finalize();
}
catch (Throwable e)
{
e.printStackTrace();
}
getActivity().finish();
super.tearDown();
}
}
The Test is not getting executed at all.
Please help me out Folks!!
Thanks.

Can you be more specific on the errors that you are encounter? maybe put some examples?
Your main activity of the application under test it is named MainActivity?
Maybe you should change the constructor from
public SampleQA(Class<MainActivity> activityClass) {
super(activityClass);
// TODO Auto-generated constructor stub
}
to
public SampleQA() {
super(MainActivity.class);
}

can anyone give me some advice to find the reason.
That is really odd thing to happen. Please read the code for two classes.
https://github.com/openjdk-mirror/jdk7u-jdk/blob/master/src/share/classes/java/lang/AbstractStringBuilder.java
https://github.com/openjdk-mirror/jdk7u-jdk/blob/master/src/share/classes/java/lang/StringBuffer.java
AbstractStringBuilder has constructor with no args which doesn't allocate the field 'value', which makes accessing the 'value' field being NPE. Any constructors in StringBuffer use that constructor. So maybe some odd thing happens in serialization/deserialization and unfortunately 'value' field in AbstractStringBuilder is being null.
Maybe initializing totalCmds in prepare() would be better, and also you need to consider synchronization (thread-safety) between bolts. prepare() can be called per bolt instance so fields are thread-safe, but class fields are not thread-safe.
I think I find the problem maybe;
the key point is
"StringBuffer _totalCmds = new StringBuffer(totalCmds);" and " totalCmds.append(lastCommands);//line 61"
when new a object, It takes serval steps:
(1) allocate memory and return reference
(2) initialize
if append after (1) and before (2) then the StringBuffer.java extends AbstractStringBuilder.java
/**
* The value is used for character storage.
*/
char[] value;
value is not initialized;so this will get null:
#Override
public synchronized void ensureCapacity(int minimumCapacity) {
if (minimumCapacity > value.length) {
expandCapacity(minimumCapacity);
}
}
this blot has a another question, some data maybe lost under a multithreaded environment

Is TextToSpeech supported on Google Glass?

I was wondering if TextToSpeech is supported on Google Glass?
I did something like this:
public class TextToSpeechController implements TextToSpeech.OnInitListener{
private Context mContext;
private TextToSpeech tts;
public TextToSpeechController(Context context) {
Log.e("TEXT TO SPEECH CONTROLLER", "controller");
mContext = context;
tts = new TextToSpeech(context, this);
}
#Override
public void onInit(int status) {
Log.e("INIT TTS", "INIT");
if (status == TextToSpeech.SUCCESS) {
int result = tts.setLanguage(Locale.ENGLISH);
if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
Toast.makeText(mContext, "This Language is not supported", Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(mContext, "Ready to Speak", Toast.LENGTH_LONG).show();
speakTheText("Welcome to Vision Screening App");
}
}
else {
Toast.makeText(mContext, "Can Not Speak", Toast.LENGTH_LONG).show();
}
}
public void stopTTS(){
Log.e(".....TTS", "SHUTDOWN");
tts.stop();
tts.shutdown();
}
public void speakTheText(String str){
Log.e("SPEAK TEXT!!!!", "SPEAK TEXT");
tts.speak(str, TextToSpeech.QUEUE_FLUSH, null);
}
}
and in my Activity (onCreate) I have:
controller_tts = new TextToSpeechController(getApplicationContext());
I face several problems :
First of all the onInit method is not called at all, only at the moment when I exit the current Activity.
Somehow, after using TTS, the speeker's volume turns to mute and I cannot turn the volume back from the settings(only after I reboot the Glasses)
Am I doing something wrong? or simply Google Glass does not support TTS, even thought is hard to believe that.
Any suggestion is welcome! Thank you very much!:)
Is it possible that you are calling stopTTS before TextToSpeech is initialized?
This works just fine for me on Glass:
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.view.MotionEvent;
import android.widget.TextView;
import java.util.Locale;
public class TTSTestActivity extends Activity
implements TextToSpeech.OnInitListener {
private TextToSpeech tts;
private boolean initialized = false;
private String queuedText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView view = new TextView(this);
view.setText("Tap Me");
setContentView(view);
tts = new TextToSpeech(this /* context */, this /* listener */);
}
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
initialized = true;
tts.setLanguage(Locale.ENGLISH);
if (queuedText != null) {
speak(queuedText);
}
}
}
public void speak(String text) {
// If not yet initialized, queue up the text.
if (!initialized) {
queuedText = text;
return;
}
queuedText = null;
// Before speaking the current text, stop any ongoing speech.
tts.stop();
// Speak the text.
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
#Override
public boolean onGenericMotionEvent(MotionEvent event) {
// On any motion event (including touchpad tap), say 'Hello Glass'
speak("Hello Glass");
return true;
}
}
With this example, anytime you tap the touch pad (or cause any other type of motion event), you should hear "Hello Glass." Note that if text is provided before TextToSpeech has initialized, then this is queued and then spoken after initialization is a success.
This does not include any tear-down, but to do that you can always put stop/shutdown of TextToSpeech in onDestroy() of the activity.

Problems with KeyListener and JOGL

I'm trying to bind a key to translate a GL_QUAD around the screen. I created a class, as I will attach below, that implements KeyListener, and within that I have a method that upon the keypress of 'd', adds 0.1 to the x coordinates of the quad vertices. Now, I have two questions relating to this.
Firstly, it doesn't seem to do anything. Upon the keypress, nothing happens to the object.
Is there a better way to achieve what I am trying to do? My end goal is to eventually end up with a sprite, that the camera is focused upon, that can move around a visually 2D game world.
Thanks for your time.

}
#Override

}
At first, you never call addKeyListener(). Secondly, you shouldn't put an infinite loop into keyPressed(). Thirdly, you use a NEWT KeyListener whereas you use an AWT GLCanvas :s Rather use GLWindow with a NEWT KeyListener or use an AWT GLCanvas with an AWT KeyListener or use NewtCanvasAWT. Finally, before writing your own example, try mine on Wikipedia in order to understand why it works.

How do I implement a mouse event outside the Java frame?

I am trying to make a return program which will press the enter key when the left mouse key is clicked...
with courtesy of
http://www.java-tips.org/java-se-tips/java.awt/how-to-use-robot-class-in-java.html (for void typing method) and "thenewboston" I have gotten so far...
I am trying to make it so that it will function in other platforms, for example: Word, Note Pad and not just on a JFrame
This is what I have up till now...
import java.awt.event.MouseEvent;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.Robot;
import java.awt.event.KeyEvent;
public class MW3Tool
{
public static void main (String[] args)
{
Robot enter = new Robot();
int num;
return count = 0;
num = count * 3;
Control c = new Control();
for (int k = 1; k <= num; k++)
{System.out.println("H");}
/* try {
Robot robot = new Robot(); // Going to be used to electronically hit the enter key later.
robot.delay(5000);
robot.setSpeed(10);
for (int k = 1; k<= num; k ++)
robot.keyPress(KeyEvent.VK_ENTER);
}
catch (AWTException e) {
e.printStackTrace();
} } */
}
private class Control implements MouseListener

{
count++;
}
public void mousePressed(MouseEvent event)
{
useless++;
}
public void mouseExited(MouseEvent event)
{

}
}
}
My errors:

private class Control implements MouseListener
^
4 errors
----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.
Sorry for my inefficient methods (newly affiliated with Java)
Any help will be appreciated... thank you...
First error: Are you trying to initialize an Integer? Wrong syntax. Use
int count = 0;
Second error: Solving the first error will solve this error.
Third error: Instead of saying
private class Control implements MouseListener { ... }
Say
private static class Control implements MouseListener { ... }
Last error:
See the MouseListener Javadocs:
Method Summary
void mouseClicked(MouseEvent e)
Invoked when the mouse button has been clicked (pressed and released) on a component.
void mouseEntered(MouseEvent e)
Invoked when the mouse enters a component.
void mouseExited(MouseEvent e)
Invoked when the mouse exits a component.
void mousePressed(MouseEvent e)
Invoked when a mouse button has been pressed on a component.
void mouseReleased(MouseEvent e)
Invoked when a mouse button has been released on a component.
You MUST override all of these methods in the Control class for your program to work.
Hope this helps!

JavaFX How to change ProgressBar color dynamically?

I was trying to solve my problem with colored progress bars in this thread. The solution was present, but then I ran into another problem: I can't change color dynamically from my code. I want to do it right from my code, not with pre-defined .css. Generally I can do it, but I run into some difficulties when I try to do it with more than one progess bar.
public class JavaFXApplication36 extends Application {
#Override
public void start(Stage primaryStage) {
AnchorPane root = new AnchorPane();
ProgressBar pbRed = new ProgressBar(0.4);
ProgressBar pbGreen = new ProgressBar(0.6);
pbRed.setLayoutY(10);
pbGreen.setLayoutY(30);
pbRed.setStyle("-fx-accent: red;"); // line (1)
pbGreen.setStyle("-fx-accent: green;"); // line (2)
root.getChildren().addAll(pbRed, pbGreen);
Scene scene = new Scene(root, 150, 50);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
}
I always get 2 red progressbars with it! It seems that code in line (1) changes the style of ProgressBar class, not the instance.
Another strange moment is that deleting line (1) don't result in 2 green progress bars. So I can figure that line (2) is completely useless!! WHY?! That's definitely getting odd.
Is there any way to set different colors for separate progressbars?
See also the StackOverflow JavaFX ProgressBar Community Wiki.
There is a workaround you can use until a bug to fix the sample code in your question is filed and fixed.
The code in this answer does a node lookup on the ProgressBar contents, then dynamically modifies the bar colour of the progress bar to any value you like.

layout.getChildren().setAll(aquaBar, fireBar);
layout.setStyle("-fx-background-color: -fx-box-border, cornsilk; -fx-padding: 15;");
stage.setScene(new Scene(layout));
stage.show();
aquaBar.wasShown();
fireBar.wasShown();
}

}
};
public PickedColorBar(double progress, Color initColor) {
bar = new ProgressBar(progress);
picker = new ColorPicker(initColor);
setSpacing(10);
setAlignment(Pos.CENTER);
getChildren().setAll(bar, picker);
}
// invoke only after the progress bar has been shown on a stage.
public void wasShown() {
if (!wasShownCalled) {
wasShownCalled = true;
setBarColor(bar, picker.getValue());
picker.valueProperty().addListener(COLOR_LISTENER);
}
}
private void setBarColor(ProgressBar bar, Color newColor) {
bar.lookup(".bar").setStyle("-fx-background-color: -fx-box-border, " + createGradientAttributeValue(newColor));
}
private String createGradientAttributeValue(Color newColor) {
String hsbAttribute = createHsbAttributeValue(newColor);
return "linear-gradient(to bottom, derive(" + hsbAttribute+ ",30%) 5%, derive(" + hsbAttribute + ",-17%))";
}
private String createHsbAttributeValue(Color newColor) {
return
"hsb(" +
(int) newColor.getHue() + "," +
(int) (newColor.getSaturation() * 100) + "%," +

}
}
}
The code uses inlined string processing of css attributes to manipulate Region backgrounds. Future JavaFX versions (e.g. JDK8+) will include a public Java API to manipulate background attributes, making obsolete the string processing of attributes from the Java program.
