Android : Compile / Running Tests By Pointing A Standard JUnit?
Aug 18, 2010
It appears that Android supports JUnit 3 out of the box.�However, I have some pre-existing JUnit 4 unit tests that I'd like to try on Android. I've tried adding the JUnit 4 jar to eclipse and compiling/ running the tests by pointing a standard JUnit run against them, but nothing seems to happen.�There's no evidence in the eclipse console or the Android emulator that any tests have been run.
Can anyone with knowledge about this subject comment?�Is it even possible to run JUnit 4 tests under Android, and if so, is there a step-by-step explanation as to how to achieve this (preferably under Jetbrains IDEA IDE, and/or Eclipse).

I cannot run android junit tests for classes sitting in main android project that implement interfaces that reside in other included projects. Depending on SDK version I get different errors: from "Test run failed:" on 1.5 and 1.6 and spurious process death to a more polite "NoClassDefFoundError" on SDK 2.0. This happens only on instantiation of classes that reside in the Android project and implement interfaces residing outside that android project. There is no problem instantiating classes that do not fall into this category (i.e. android only or library only classes).
Android project by itself works fine with these classes - it is just the test set-up doesn't and project inclusion/classpath seems to be ok. Test project includes all projects that main project includes. NoClassDefFoundError makes little sense here given that the classloader can see and instantiate classes sitting right next to the ones that do not work. Did anyone else run into this or found a way to set-up android based tests in a multi-project set-up? Below is more detailed set-up and test explanation: 1) Library project: FooLib public interface IFoo { ... }

Failing JUnit tests, not breaking my Ant script like I expect?
My continuous integration server runs an Ant script, which calls something like:
/tests/ant run-tests
My JUnit tests run, but with errors:
CODE:..............
The errors are OK, but my build script keeps going (eventually publishing my broken app to my testers - bad!). What I would expect is for the instrimentaiton to throw a build error, so my continuous integration server (TeamCity in this case) realises that something has gone wrong and reports a broken build. The "failonerror" is already set in the relevant macrodef, so I'm not sure what else I can do?

I am building an Android hello world application in Netbeans. It's building properly and I am able to run in the emulator also. But when creating and running the Junit test I get a java.lang.NoClassDefFoundError.

I'm trying to run unit tests on the android platform in accordance with tutorial. Say, for example, I want to run tests for Email application. I open /apps/Email/tests/AndroidManifest.xml file, look for the <manifest> element, and look at the package attribute, which is com.android.email.tests, and in the <instrumentation> element I look at the android:name attribute, which is android.test.InstrumentationTestRunner.

I get the following stack trace when running my Android tests on the Emulator code...
I run my tests from an extra project. And it seems there are some problems with loading the classes from the other project. I have run the tests before but now they are failing. The project under tests runs without problems.
Line 14 of the Helper Class is:
this.httpHelper = new HttpHelper(userProfile);
I start a HttpHelper class that is responsible for executing httpqueries. I think somehow this helper class is not available anymore, but I have no clue why.

"Hello, World" and "Hello, Testing" tutorials I created an android application created with Eclipse, along with a corresponding Android Test Project.The tests run fine once. After that, in order for me to run the tests again, I have to close the emulator.If I don't close the emulator, the Eclipse console get stuck on "Installing instrumentation android.test.InstrumentationTestRunner on device emulator-5554"... Nothing happens after that.I've been told to exit out of the application under test in the emulator in order to run the test again. Unfortunately the emulator doesn't have the app pulled up (it's in the normal "locked" position and when unlocked brings up the home screen) and even if I do pull it up then exit, it doesn't seem to let me run my tests again.All the example videos and tutorials all stop at the first run of a test. I have yet to see anyone anywhere run a test a second time!

I have an Android project that I have been working on and debugging just fine for several months, but for some reason it is now consistently hanging at the "Runnning tests..." step. I have experienced intermittent hangs from the beginning, but a simple retry and/or restart of Eclipse or the emulator usually resolves it. But now I am just dead in the water.I can run my tests fine, and I can debug my actual program, but I can't debug my tests.I have tried creating a new emulator and that doesn't fix it. I also cleared all my breakpoints and that had no effect.As far as what has changed lately, the primary thing is that I upgraded to rev 7 of the SDK tools. Also, I recently did some debugging (of the program not the tests) on an actual device (not the emulator). Can't see how that would impact it but I thought I would mention it.Actually I had to set Debuggable to "true" in the app manifest to get device debugging to work. Although I have never had that set in my test project, I set it, and that also had no effect on the issue.I'm running out of ideas, and I would greatly appreciate some pointers.

when I compile android (http://source.android.com/download) it does not compile some source files. For example there is external/bluetooth/bluez/sbc/sbc.c which is not compiled. There are also other such files.
It's possible those files need not to be compiled. Or it might be that I need some special configuration to compile them.
Either way, if it is possible, I'd like to compile them. Is there some way to do it? Maybe some "compile_all" make target? (I believe the reason why I want to compile all source files is not important)

I'm trying to implement something that I don't even know if it's possible. So I have this class which implements a SensorEventListener like this:
private SensorEventListener mySensorEventListener = new SensorEventListener(){
@Override public void onAccuracyChanged(Sensor sensor, int accuracy) {
} @Override public void onSensorChanged(SensorEvent event) {
myCompass.updateDirection((float)event.values[0]); } };
And a class that handles the way the compass looks like this:
public static class compassLook extends View {
private Paint paintPointer = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintCircle = new Paint(Paint.ANTI_ALIAS_FLAG);
private Paint paintLeters = new Paint(Paint.ANTI_ALIAS_FLAG);
private boolean firstDraw; private float direction = 0 ;
public compassLook(Context context) { super(context); init();
} public compassLook(Context context, AttributeSet attrs) { super(context, attrs); init();
} public compassLook(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle); init(); } private void init(){
paintPointer.setStyle(Paint.Style.STROKE); paintPointer.setStrokeWidth(3);
paintPointer.setColor(Color.argb(255, 209, 114, 2)); paintCircle.setStyle(Paint.Style.STROKE);
paintCircle.setStrokeWidth(2); paintCircle.setColor(Color.argb(150, 255, 255, 255));
paintLeters.setStyle(Paint.Style.STROKE); paintLeters.setStrokeWidth(1);
paintLeters.setColor(Color.argb(230, 255, 255, 255)); paintLeters.setTextSize(12);
firstDraw = true; } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension(MeasureSpec.getSize(widthMeasureSpec),
MeasureSpec.getSize(heightMeasureSpec)); } @Override protected void onDraw(Canvas canvas) {
int cxCompass = (getMeasuredWidth()/2); int cyCompass = (getMeasuredHeight()/2);
float radiusCompass; if(cxCompass > cyCompass){ radiusCompass = (float) (cyCompass * 0.9);
} else{ radiusCompass = (float) (cxCompass * 0.9);}
canvas.drawCircle(cxCompass-50, cyCompass, radiusCompass, paintCircle);
if(!firstDraw){ // Desenho da linha que aponta canvas.drawLine(cxCompass-50, cyCompass,
(float)(cxCompass-50 + radiusCompass * Math.sin((double)(- direction) * 3.14/180)),
(float)(cyCompass - radiusCompass * Math.cos((double)(-direction) * 3.14/180)),
paintPointer); double mLatitude = (mLocation.getLatitude() / 1E6);
// I get this value from a LM request double mLongitude = (mLocation.getLongitude() / 1E6);
// I get this value from a LM request double picLatitude= Double.parseDouble(picLatitudeString);
// I get this value from a bundle double picLongitude = Double.parseDouble(picLongitudeString);
// I get this value from a bundle float direction = (float)
Math.toDegrees(Math.atan2(picLongitude- mLongitude, picLatitude-mLatitude));
float distancia = (float) (Math.sqrt(Math.pow(mLatitude- picLatitude,
2) + Math.pow(mLongitude-picLongitude,2)))/2;
//Desenho do texto que indica a distancia
canvas.drawText(String.valueOf(distancia) + "Km", cxCompass-30,
cyCompass+20, paintLeters); } } public void updateDirection(float dir)
{ firstDraw = false; direction = dir; invalidate(); } }

If I pass http://www.ebay.com to this. Somewhere along the way ebay changes my url, perhaps a redirect. What's weird is Android java can't open the page. u = new URL(txturl.getText().toString());
I get the error below as it apparently opening the new mobile site. I'm just wonder at what point my url changes and If I somehow stop this. It does not appear to happen if I point to yahoo, google, amazon or other major sites. I just noticed this in my testing.

I'm writing program for Android (SDK 1.5). I would like to know how to add/register one of my program activities in "Home Screen -> Menu -> Add-> Shortcuts" (or on Hero "Home Screen -> Menu -> Add to Home-> Shortcut") so that user will be able to add it to his home screen. Is there an Intent Filter or any other way to achieve that?

Does the USB standard have a standard power output?

I'm having troubles with ADT and JUnit Testing.
When I use HttpClient classes, my JUnit tests fail with errors like: java.lang.NoClassDefFoundError: org/apache/http/client/HttpClient.
I run my tests in Eclipse as "JUnit Tests" (not "Android JUnit Tests") with the "Android Test Launcher". An idea about how to resolve this problem?

Been slowly building my app and now JUnit is crashing regularly with logcat as below.
There are no other real hints. No relevant code as this can happen at multiple points of the code. There are no other errors or exceptions thrown. As far as I can tell there is plenty of memory left and my app does not appear to have any leaks I can find during a run outside of JUnit.

I'm developing an Android application with database storage.
I want to test some classes that I use to access database.
I've found ActivityInstrumentationTestCase2 to test Activities but I haven't found anything to test classes.
How can I do that? I haven't used jUnit before.

As the first step of the port of my existing Java swing application to Android, I'd like to get the non-UI logic unit tests running on the Android device. The unit tests are written against JUnit 4. It looks like Android 2.2 comes with JUnit 3 as the default. Is there an easy way (or any way) to bootstrap JUnit 4 as the test runner?
I am using IDEA as my dev environment, but it doesn't appear there's any settings that will allow me to specify JUnit 4.

I am developing a simple android application using eclipse.I wrote a JUnit TestCase for a class I wrote.One particular test compares two 2d arrays so see if they are equal. If they are not equal the test fails.When the test fails I would like to print out the contents of the offending array to see what went wrong. I have tried System.out.print and it doesn't show up in the console or JUnit results.What am I doing wrong?Is it even possible?

After following some instructions on Diego Torres blog I am able to test my classes using the regular Eclipse JUnit test-runner, however I also want to be able to run my unit tests from within the emulated android environment. For now this should make no real difference since the classes I am working on do very basic numerical or networking tasks, but obviously anything which involves the UI or Android API specific functions can only ever be tested on the emulator.
I set up a new run configuration of type AndroidJUnitTest wich uses the ndroid.test.InstrumentationTestRunner, however whenever I fire up the test I get the following error in the console:
