java.lang.NullPointerException: java.lang.NullPointerException
I am trying to automate the android application by using monkey runner i.e UI testing by using python scripts
Can any body help how to solve the Null point exception for the above code ?
If I look at the stack trace of your error, this looks like there is an issue with your jython library of monkeyrunner.
Because, there is an exception occurring from reflection package which is failing to invoke the native java call. Make sure your monkeyrunner.bat file is referencing the lib folder provided with android SDK.
Updating the android SDK also may help.
I had same issue.At last I found that is a hardware issue, so please ran it on emulator first or another phone.

Greetings
I have deployed a simple JavaFX application using msi installer that was created by jpackage. When double-clicking on the application icon installed in Windows 10 "program files" directory, it displays an error "Failed to launch JVM". Prior to deployment, I tested the application jar file from the command prompt without any problem. When checking the application installation directory (under "C:\Program files") it has all the runtime dlls and so on, so I am not sure what causes this error? Here is the japckage command I used to build the runtime image:
jpackage --type msi --name FileChooser -p "%JAVAFX_HOME%\lib;%M2_REPO%;org\openjfx\mavenfxfilechooser\mavenfxfilechooser.jar" --module "org.openjfx.mavenfxfilechooser/org.openjfx.mavenfxfilechooser.FileChooserApp"
Update
Following the recommendation given in the comment section, I installed the JMODS on my machine and issued a jpackage command line to point to the JMODS files instead of JAVAFX_HOME as follow:
jpackage --type msi --name FileChooser -p "%JMODS_HOME%;%M2_REPO%;C:\Users\hrh74\Downloads\Lib\file\org\openjfx\mavenfxfilechooser" --module "org.openjfx.mavenfxfilechooser/org.openjfx.mavenfxfilechooser.FileChooserApp"
I installed the application using the MSI runtime image and this certainly solved the" Failed to launch JVM" problem. The application started, however, I have a WebView component that should display content from https://us.yahoo.com when the user clicks on a "Yahoo" button and this doesn't seem to be working when the application run as a self-contained app but it works when I run the jar file from the command line. Do I need to add anything to the jpackage?
Please let me know if the source code and FXML file are needed.
Thanks
Your original problem has to do with missing native code. But you appear to have already solved that problem by using the JMOD files for JavaFX provided by Gluon. So I'll try to help solve your other issue regarding https://us.yahoo.com not loading in the WebView once you create a self-contained application.
When trying to load that website myself I was running into the same issue as you. Though sometimes I'd get a "we're working on the problem" page response, other times the entire application would become unresponsive, and yet other times nothing would happen (the load would just seem to fail "gracefully"). This happened with other websites as well, not just Yahoo. After some testing I was finally able to get the following error:
java.lang.Throwable: SSL handshake failed

That indicated to me the application created by jpackage was missing some crypto libraries. From here I just guessed, but inclulding:
--add-modules jdk.crypto.cryptoki,jdk.crypto.ec
When running jpackage seemed to solve the problem. I don't know if both modules are needed, or if only one is needed (or if adding either one implicitly adds the other).
Side note: When scrolling through https://us.yahoo.com I would frequently get the following warnings:
Mar 05, 2021 12:10:40 PM com.sun.javafx.webkit.prism.WCMediaPlayerImpl onError
WARNING: onError, errCode=0, msg=Could not create player!
And:
Mar 05, 2021 12:10:41 PM com.sun.javafx.webkit.prism.WCMediaPlayerImpl$CreateThread run
WARNING: CreateThread ERROR: java.lang.UnsupportedOperationException: Unsupported protocol "data"
I would get that warning regardless of how the application was packaged. I don't know how to solve the problem, or if there even is a solution without modifying the JavaFX code itself.
Have you seen running JavaFX application after jpackage? Try to download Gluon jmods and use it instead of %JAVAFX_HOME%
I am trying to run the OWBClient.sh with the command in UNIX and I am getting the following error:
" The JVM option is invalid: -XX: MaxPermSize=256M. Could not create the Java Virtual Machine."
OWB Version: 10.2.0.5
Oracle Database : 10g

When exploring more on the above issue, I got an information that OWB 10.2 could not be run in AIX. It would be helpful if anyone can can shed some light on whether OWB 10.2.0.5 can be run on AIX?
Editing my post to share an update.I have tried to execute the owbclient.sh file by removing the -XX:MaxPermSize=256M part. I am now getting a different kind of error...

I am trying to do this project I found in instructbles.
http://www.instructables.com/id/Touche-for-Arduino-Advanced-touch-sensing/?ALLSTEPS
There is an Arduino code and a Processing code that needs to be run to implement this project.
The codes can be found here.
https://github.com/Illutron/AdvancedTouchSensing
The arduino code runs fine. But the one in processing gives a NullPointerException error and the output is just a plain white window instead of the desired graphs.
The complete error message is as follows:

A null pointer exception occurs when java can't find an index in an array at that address. Are you sure that your serial ports are valid? Have you tested serial communication using another sketch in processing?
I've been having some troubles gettin MonkeyRunner working. So far, we've tried 3 different computers and every android device we could get our hands on.

java.lang.NullPointerException: java.lang.NullPointerException
This is running on osx, the phone is a Nexus S.
The python looks like:
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
device = MonkeyRunner.waitForConnection()
I've tried this from a .py file, as well as from the interactive interpreter. I've also tried calling waitForConnection with the timeout and device id arguments, all with the same results.
Any help is appreciated, thanks!
--UPDATE--
The device is connected, on, and enabled for development. The issue with monkeyrunner seems to be limited to osx, and might have to do with jdk on osx, and might not be an issue with monkeyrunner itself.
Please verify your device 'USB debugging' is set to true.
You would find it under:
settings->application->development
type "adb devices" command in terminal
if it lists any device, then Monkeyrunner.waitForConnection() should not fail.
if device not listed, check if the usb driver is installed properly.
I'm trying to refactor a package name (pretty near the root of the project hierarchy), and I'm getting the following error (flash builder 4):

Any ideas what is wrong...and what I can do to fix it ? I queried google for it, and didn't turn up anything useful with the parameters I tried.
You can try to Restart Eclipse. Oddly that fixes a number of issues in Eclipse that happen all of a sudden with no normal explanation.
Increase the thread size of the JVM you run your IDE in?
I believe in Eclipse you could do it by adding -Xss with some value to eclipse.ini within your Eclipse installation. The setting is a JVM setting so should be added in the -vmargs section, it might be next to -Xmx which is there by default.
This may not be the best answer, but..I recommend you to try a different IDE like IntelliJ.
I've used Flash Builder before. It had always gave me problem. Usually it's because plug-in incompatible. Running tomcat in it sometimes gives me this "undead" java process that just won't die.
I'm using IntelliJ 9 now. It's autocomplete is less complete than Flash Builder, but it has a much better refactoring feature and..much MUCH better integration with other tools (like Maven).
