Returning empty screenshot on Android 4.4.2

[jhuska]

I am taking screenshot by well known way:

File screenshot = device.getScreenshotAs(OutputType.FILE);
String deviceName = device.getCapabilities().getCapability("deviceName").toString();
File destFile = new File(BUILD_DIR + File.separator
            + deviceName + "-" + screenshotName + ".png");
try {
   FileUtils.copyFile(screenshot, destFile);
} catch (IOException ex) {
   throw new RuntimeException(ex);
}

It works just fine on my devices, expect Samsung Galaxy S4, which is running Android 4.4.2.

In Appium server log I can find these lines:

/wd/hub/session/5a1b71ee-5b92-468d-8c54-eb1356f837dc/screenshot
[debug] executing cmd: path/to/sdk/platform-tools/adb -s [particularSerialNumber] shell "/system/bin/rm /data/local/tmp/screenshot.png; /system/bin/screencap -p /data/local/tmp/screenshot.png "

Please see that value is empty. In result it creates an empty file.

When executing those adb commands manually, it works. I am running Appium from source, with pretty much fresh master (May 4) - all found issues related to screenshots were resolved sooner.

Try with the screenshotWaitTimeout cap.

Thanks @sebv, I tried it. Unfortunately it does not help.

Is not that cap. iOS only?

Ok put it in bug, I remember it is one of the thing we have in backlog, will tackle those after current Appium rewrite effort.
