junit.framework.AssertionFailedError: 2131230724 Buttons are not found!

[GoogleCodeExporter]

Hello,

I'm new to Robotium so i'm trying to perform a simple test on an android 
calculator app.
i have 2 editTexts, a textView for result and a button "Addition":

<EditText
        android:id="@+id/EDtxt1"
        android:inputType="numberDecimal"
        android:layout_width="250dp"
        android:layout_height="40dp"
        android:layout_gravity="center"
        android:hint="Enter First Number"/>

    <EditText
        android:id="@+id/EDtxt2"
        android:inputType="numberDecimal"
        android:layout_width="250dp"
        android:layout_height="40dp"
        android:layout_gravity="center"
        android:hint="Enter Second Number"/>

    <TextView
        android:id="@+id/resultTvID"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="No Result "
        android:textSize="25dp" />

    <Button 
        android:id="@+id/addBtnID"
        android:text="Addition"
        android:layout_width="150dp"
        android:layout_height="40dp"
        android:layout_gravity="center"/>

In my robotium coding i want to enter 2 numbers & click on the "Addition" 
button.
But, i keep getting the error "junit.framework.AssertionFailedError: 2131230724 
Buttons are not found!" on button click.

this is the robotium coding:
@Test public void testAddBtn(){

        //solo.assertCurrentActivity("Check on startup", MainActivity.class);

        String appName = solo.getCurrentActivity().getClass().getSimpleName();
        solo.assertCurrentActivity("Check on startup", appName); 
        solo.waitForActivity(appName);

        EditText editText1 = (EditText) solo.getView(com.example.simplecalculator.R.id.EDtxt1);
        EditText editText2 = (EditText) solo.getView(com.example.simplecalculator.R.id.EDtxt2);
        //Button button = (Button) solo.getView(com.example.simplecalculator.R.id.addBtnID);

        solo.enterText(editText1, String.valueOf("10"));
        solo.enterText(editText2, String.valueOf("5"));
        solo.goBack();
        solo.clickOnButton(com.example.simplecalculator.R.id.addBtnID);
}

I'm using robotium-solo-4.1.jar with sdk17.

Thank you in advance.
:)

ClickOnButton() is used with index. What you want to do is clickOnView(button); 
Please keep this tracker for issues only.

• Changed state: Invalid

[GoogleCodeExporter]

this didn't work too:
        Button msButton = (Button) solo.getCurrentActivity().findViewById(
                com.example.simplecalculator.R.id.addBtnID);

        solo.clickOnView(msButton);

in the manifest xml, i also added
<uses-sdk android:targetSdkVersion="YOUR_VERSION" /> 
<supports-screens android:anyDensity="true"/> 

i still get the same error.

Do this:

Button msButton = (Button) solo.getView(
                com.example.simplecalculator.R.id.addBtnID);
solo.clickOnView(msButton);

does that mean the the button is beeing clicked on & there is another problem.

the expected result when i click on the button is a TextView takes "Hello". 
What exactly can go wrong.

You need to follow the tutorial "Test Android Calculator Application with 
Robotium" :

by the way i'm using 4.2.2, API17

i downloaded the 2 projects AndroidCalsulator & AndroidCalculatorTest.
when u run the AndroidCalculatorTest.

i get the error:
junit.framework.AssertionFailedError: EditText is not found!
at com.jayway.android.robotium.solo.Waiter.waitForAndGetView(Waiter.java:492)

5)
at 
android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1661)

the problem happens in 1st
        EditText FirsteditText = (EditText) solo.getView(R.id.EditText01);
        solo.enterText(FirsteditText, String.valueOf(firstNumber));

i think the problem is more than how to create the test case
could it be a framework issue?
should i use an older API?

Hi i've got couple of things

1. In case of your main problem 

//solo.assertCurrentActivity("Check on startup", MainActivity.class);
String appName = solo.getCurrentActivity().getClass().getSimpleName();
   solo.assertCurrentActivity("Check on startup", appName); 
    solo.waitForActivity(appName);

   EditText editText1 = (EditText) solo.getView(com.example.simplecalculator.R.id.EDtxt1);
    EditText editText2 = (EditText) solo.getView(com.example.simplecalculator.R.id.EDtxt2);
        //Button button = (Button) solo.getView(com.example.simplecalculator.R.id.addBtnID);

        solo.enterText(editText1, String.valueOf("10"));
        solo.enterText(editText2, String.valueOf("5"));
        solo.goBack();
        solo.clickOnButton(com.example.simplecalculator.R.id.addBtnID);
}

why are you using "solo.goBack()" ? , it is the one cause of issue.

2. Secondly 

solo.clickOnButton() need index not the id of view.

About 

junit.framework.AssertionFailedError: EditText is not found!

Issues with AndroidCalculatorTest, I've just run it on Galaxy S4 with 4.2.2, 
its working fine here. 

Can you please tell me are you using on real device ? what is the device info?

[GoogleCodeExporter]

Thank you both so much for your help,
i figure out the issue & it's not related to the code itself

when i change the android device to Nexus S it worked.
on other devices, lower performnce, it didn't work. it didn't find the button.
which could be understandable because maybe the button is too big for the 
screen itself or something like that.
thank you so much again.
my problem is officially solved.
kais.
