Hi,
I am using Robotium and it is very helpful for me. But now i m
in a situation where i need to take screenshot of the emulator, i
think currently Robotium dont have any methods or class for taking
screenshot.I have a screenshot class which takes screenshot when
called independently, but when i called that class inside robotium, i
m getting error saying " Test run failed: Process crashed".
Please help me to get out of this.
Thanks

So you can not call the screen shot class from your test case? What does the log say?

Yes Renas I am not able to call the Screenshot class.

The problem you are experiencing is because of the fact that adb is
busy with the JUnit tests. So therefore it does not accept that you
try to use it (as it is already in use). There is however another way
in which you can take screenshots and save them on the sd card:
public static String SCREEN_SHOTS_LOCATION="/sdcard/";
public static void takeScreenShot(View view) throws Exception
{
takeScreenShot(view, "default");
}
public static void takeScreenShot(View view, String name)
throws
Exception {
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap b = view.getDrawingCache();
FileOutputStream fos = null;
try {
File sddir = new File(SCREEN_SHOTS_LOCATION);
if (!sddir.exists()) {
sddir.mkdirs();
}
fos = new
FileOutputStream(SCREEN_SHOTS_LOCATION+name+"_"
+ System.currentTimeMillis() +
".jpg");
if (fos != null) {
b.compress(Bitmap.CompressFormat.JPEG,
90, fos);
fos.close();
}
} catch (Exception e) {
}
}
//call
takeScreenShot(solo.getViews().get(0), "testname");

Thank you so much Renas.
I have one doubt, is it possible to save the taken screenshot in local
disk?
Because i need to use that screen shot for image comparison.
Or can i use the saved screen shot from SD card for image comparison?
Thanks.

You can do a "adb pull" of the screen shot file after the tests are
done. Adb pull will transfer the file from your device to your
computer.

Hi Renas,
Screenshot code is working fine, it is successfully saving in
sdcard.
Also using "adb pull" I am able to pull the image to my local disk
when used using command prompt, but the problem is when i cal it
inside my code its giving error.
Is it possible to use the commands "adb pull" inside robotium?
Below is my code
public void testAddNote() throws Exception {
Thread.sleep(5000);
solo.clickOnMenuItem("Settings");
Thread.sleep(5000);
takeScreenShot(solo.getViews().get(0), "testAddNote");
Thread.sleep(3000);
String[] command = new String[]{"adb", "pull", "/sdcard/", "C:\\"};
Process child = Runtime.getRuntime().exec(command);
}

Hi,
No you can not use it inside of Robotium. What you can do is create a
small script (e.g. bash script) that not only runs the tests by the
use of "adb instrument ...." but also after the tests are done does an
adb pull.

No you can not use it inside of Robotium. What you can do is create a
small script (e.g. bash script) that not only runs the tests by the
use of "adb instrument ...." but also after the tests are done does an
adb pull.

Once again thank u Renas.
But actually what i thought is compare the taken screen shot image
with the expected image, if it matches testcase should pass else it
should fail.
So can i call image comparison class inside robotium by passing image
which is stored in sd card and the expected image which is there in my
local disk?
Please guide me, how can i move forward? which is better to do?
Thanks

I think that it's more convenient to do the comparison in JAva code
that doesn't run inside Android, because it's easier - and you usually
can't rely on a direct pixel-by-pixel comparison - I'm telling you
this because, even though I've never done this so far, I've recently
talked with a guy who's experienced in this task, and he told me that
he first subtracts the two images and then runs a filter on the result
that tolerates some slight changes. I'd say that in plain Java there
are more readily available imaging libraries (such as JAI) that should
make the task a matter of a few lines of code.

Thanks Fabrizio for your inputs..
Outside android my comparison code is working good but i want to
include this as part of my test so that i would get result whether
test passed or failed depending on this comparison.
Or is it possible to take screenshot on test failure?
Thanks

Hi all - unfortunately I can't help much in this area - my original email
was three years old and in recent time I've not worked in this area with
Robotium... so I don't recall what I was doing :-(
