I'm trying to input text into the current running application (not my own) using the adb input text method, this works if I run it from the command prompt such as 'adb input text "Android" and also if I run it from terminal emulator. However the below code run successfully but produces no output on the screen.. I have also tried various other methods to run shell commands which have also not failed but not output any text..
Anyone know what I am doing wrong?
try {
//Runtime.getRuntime().exec("su");
Runtime.getRuntime().exec("input text \":\"");
} catch (IOException e) {
e.printStackTrace();
}
To inject text into an android app the injector must have
android.permission.INJECT_EVENTS
permission, so it must be a system app.
Your Runtime.getRuntime().exec has not this permission.
If you run your command from Native executable, it works fine.
Build a NDK binary and execute:
char * command = "input text hello%sworld\0";
system( command );//fork and exec input text ...
Maybe you need to use :
Runtime.getRuntime().exec("shell input text");

My os is MAC OS 10.11.3.
I using Spark as our IM（Instant messaging），but when the IM log out，IM give an error，said：
java.io.IOException: Cannot run program "open": error=2, No such file or directory .
But when Eclipse runs it， it worked well，and when I wrapped it a mac package and installed it and run it, click "log out" button, it throws errors.
In program, when I log out，I launch a new IM，meanwhile，I killed the old IM application.
Furthermore，in terminal，no matter what I run how many times “open -a Spark”，it just open the same IM，
The source as follows：
public boolean restartApplicationWithScript() {
String command = null;
try {
if (Spark.isMac()) {
command = "open -a " + Default.getString(Default.SHORT_NAME);
}
String commands[] = {"open", "/Applications/Spark.app"};
Runtime.getRuntime().exec(commands);
System.exit(0);
return true;
} catch (IOException e) {
Log.error("Error trying to restart application with script", e);
return false;
}
}
The exception seems to be saying that it cannot find the open command. That seems a bit odd, since it is a standard MacOS command. So I suspect that the reason that it cannot be found is that it is not on the PATH.
Try giving the absolute pathname for the open command. Running which open should tell you what it is.
If open is a shell builtin on MacOS, then you will need to create a subshell to run the command.
Thanks for all， i solved it by 2 step ：
1， cmdline = { "open", "-na", "Microsoft Excel" }; this add a "n" ,otherwise，it will open the same app 。
2，chmod -R 777 youAppPath，if not do this ，the app can't issue the command
I wrote a Java program some time ago that automatically opens a webpage before I get to work in the morning. I do this by calling a batch file from Java, which opens the webpage. This program worked great for about three or four months without any problems, but one day it just stopped working. I have tried opening the webpage from within Java as well instead of the batch file, but I consistently run into a problem. This is the process I use:
I exported my program as a runnable JAR and converted it to an EXE using Launch4j. In my Windows task scheduler I schedule it to run at 5:30am every morning.
My Java program calls the batch file that is stored on my desktop
The batch file opens Chrome and calls the webpage to open
When I run the Java program EXE manually (double-click from the desktop) it runs correctly, calls the batch file, and opens the webpage. However, when I try running the EXE from the Windows task scheduler it does not (visibly) open the webpage. It does appear to run Chrome in the background (according to the task manager/Process Explorer) but the webpage itself doesn't seem to open (I can tell because the webpage I open should be playing music, but I hear nothing).
This is the Java function I use to run the batch file:
public static void openWebpage() throws Exception {
String[] startupBat = {"cmd", "/c", "start", "/B", System.getProperty("user.home") + "\\Desktop\\WebpageStart.bat"};
ProcessBuilder pb = new ProcessBuilder(startupBat);
try {
webpage = pb.start();
} catch (IOException e) {
logWriter.write(tf.format(new Date()).toString() + " - Unable to start webpage");
}
if (webpage != null) {
try {
webpage.waitFor();
} catch (InterruptedException e) {
logWriter.write(tf.format(new Date()).toString() + " - Webpage startup interrupted");
} finally {
webpage.destroy();
}
}
}
And here are the contents of the batch file I use to start the webpage:
#echo off
start "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://www.myWebpage.com
Once again, everything works fine when I run the Java EXE manually, but when I try to run it from the task scheduler the webpage doesn't appear to open. What could cause this sort of behavior? What changes when the task scheduler runs a program vs. when it is manually run?
A few things to check
Which user is the scheduled task running as? Is it the same user as the one double clicking on the icon?
Have you changed your password recently? You might need to update the password on the scheduled task
Go to the windows event viewer, are there any errors in there?
I have Nodejs - server.js code in my windows system from which i want to execute a simple jar file.
So i used follwoing code :
cmd = "java -jar C:\\libs\\sample.jar";
var Exec =exec(cmd, function(error, stdout, stderr) {
if (error !== null) {
console.log('exec error: ' + error);
}//end of if
});//end of exec cmd
When i run the "node server.js" in command prompt ,jar is executing perfectly.
After this i made this "node server.js" command as service by referring following link :
https://github.com/coreybutler/node-windows
i.e node-windows,But now once its become service i am unable to exectue simple.jar,even i am enble to run simple "java -version" command.
Except java all other command are working fine even after i made nodejs as service.
Please help me out.....
New Update : After testing lot of different cases, Finally i came to know that jars containing JFrame components is not opening...how to solve this
I have a python compiled script (script.pyc , I haven't the .py file)that work well from my windows command prompt, and I want to execute it from my Java's application.
I tried to use runtime() method :
Runtime runtime = Runtime.getRuntime();
runtime.exec(new String[] {"C:\\toto\\tools\\script.pyc" ,"arg","arg2" });
but I get an error :
Exception in thread "main" java.io.IOException: Cannot run program "C:\Nuance\VoCon Hybrid\SDK_v4_3\tools\clctodict.pyc": CreateProcess error=193, %1 n?est pas une application Win32 valid
The script work well in my terminal ("arg" is a txt file, "arg2" is the output name, and the script does its job without any problem).
I also try to launch my script with getDesktop() :
File fie = new File("C:\\toto\\tools\\script.pyc" ,"arg","arg2");
Desktop.getDesktop().open(fie);
There is no problem, but I can't add argument, so I can just see a terminal windows opening during a few second before disappearing instantly.
I have also tried to use JPython, without success too (maybe we can't use methode "execfile" on a .pyc????)
You can do something like
Process p = Runtime.getRuntime().exec(new String[]{"python.exe" ... other args)
Then you can invoke p.waitFor() to wait for the end of the process and p.exitValue() to test if the program exited successfully.
You can also get the output stream via p.getOutputStream() to retrieve the text printed by your python script
Please refer to the class documentation for further information : http://docs.oracle.com/javase/6/docs/api/java/lang/Process.html
Just like you need a jvm to run a .class, you need a python interpreter to run a .pyc.
Try something like:
runtime.exec(new String[] {"c:\\Python26\\bin\\python.exe", "C:\\toto\\tools\\script.pyc" ,"arg","arg2" });
I wrap my Java Swing application as an exe using Jsmooth but I can see no way to take advantage of Java 6 splash screen option. I have the following manifest file:
Manifest-Version: 1.0
SplashScreen-Image: resources/LOADLOGO.png
Main-Class: se.bookingapp.UI.MainFrame
The splash screen appears if I simply click on the jar file of the application. However, the JSmooth generated exe form of the jar file does not show the splash screen somehow. Does anyone know why?
Yesterday I've finished to develop my java application and I had the same issue. If I double click the .jar file or I execute in a command line splash screen works perfectly, but when I execute the wrapped file it doesn't. Seems just JSmooth doesn't support this feature.
However I made a little trick to have a wrapped .exe and splash screen working at the same time. I made a little application called ApplicationLoader.jar that consists in a single main class that execute java -jar "Application.jar" in a command line. Here is the complete code:
public class ApplicationLoader {
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
/* First I check if the first parameter is not null and it's not an empty string */
if(args[0] != null && !args[0].trim().isEmpty()){
/* Then I use java.util.regex package to validate the parameter is a .jar file */
Pattern pattern = Pattern.compile(".*jar");
Matcher matcher = pattern.matcher(args[0]);
if(matcher.matches()){
/* Finally I define the command line like: java -jar "Application.jar" */
String command = "java -jar \"" + args[0] + "\"";
try {
Runtime r = Runtime.getRuntime();
ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/c", command);
Process p = pb.start();
p.waitFor();
} catch (IOException | InterruptedException ex) {
JOptionPane.showMessageDialog(null, ex.getMessage(), "Error executing: "+command, JOptionPane.ERROR_MESSAGE);
}
} else {
JOptionPane.showMessageDialog(null, "The argument is not a .jar file!!");
}
} else {
JOptionPane.showMessageDialog(null, "There's not a valid argument!");
}
}
}
I have this folder structure for my application:
MyApp
+-- bin
| +-- MyApp.jar
| +-- ApplicationLoader.jar
+-- MyApp.exe
So in JSmoot I changed the classpath to ApplicationLoader.jar and add the relative location to my application in Application Arguments section like this:
And that's it. I know this is not the best option but is a workaround.
However there's a little problem:
Since ApplicationLoader.jar calls a cmd.exe then the wrapped .exe and your application will execute in two different processes.
This implies that if you have to kill .exe process for some reason (unexpected crash or something), your java application still working as a java.exe process. So in that case you must kill MyApp.exe and java.exe processes. Actually if you just kill java.exe process then MyApp.exe process will finish execution by itself.
If you keep this in mind and you can live with that I think this option is quite simple and useful.
I hope this be helpful to anybody looking for a workaround to this issue.
Does it work when you execute the jar file? Open it with WinRar for example, and check if the manifest is into META-INF folder, and LOADLOGO.png is in the right folder too.
After doing that, it should work. It works for me. Nothing wrong in your manifest.
