I have the following program segment and Java ignores to process the given command. command1 = "mv output/tsk/dir1/metabolic\\ waste.txt output/converted/file16.txt"; r2 =

问题 So as the subject states I need to be able to answer a phone call programmatically in Android 4.0.3 on an HTC OneX. I have read several places that the MODIFY_PHONE_STATE permission has been revoked by Google so to do this task you need a work around. I have looked into two avenues so far: (1) Following Guy's post here and using a BroadcastReceiver (2) Using the following code to try and hit a key event through a shell command. final Runtime r = Runtime.getRuntime(); try { Process process = r

问题 I'm launching wkhtmltopdf from within my Java app (part of a Tomcat server, running in debug mode within Eclipse Helios on Win7 64-bit): I'd like to wait for it to complete, then Do More Stuff. String cmd[] = {"wkhtmltopdf", htmlPathIn, pdfPathOut}; Process proc = Runtime.getRuntime().exec( cmd, null ); proc.waitFor(); But waitFor() never returns. I can still see the process in the Windows Task Manager (with the command line I passed to exec(): looks fine). AND IT WORKS. wkhtmltopdf produces

问题 So we have a java process that runs as a windows service. It needs to execute a command with Runtime.getRuntime().exec(command) . The command it executes requires UAC. This is on windows server 2008 and sounds like you cannot disable UAC for a single executable so is there any other way to make this work? 回答1: If your Java application runs as a windows service, it most likely runs under one of the system accounts: SYSTEM (most probable), LOCAL SERVICE, or NETWORK SERVICE. Thus if the service

问题 I have the following line to run a batch file, Process process = Runtime.getRuntime().exec("cmd /c start rake.bat"); But I want it to run in the background and not display the command line to the user. How can I change it to do this? The problem is that the command window opens and intrupts the programs GUI. I just want the command window to not be visible while it is executing the batch file. 回答1: Removing the 'start' completely will do what you want (as this is what is creating the window):

问题 I have a Java program that executes Runtime.getRuntime().exec("ls -l"); many times, once for each directory in the system. My test system has more than 1,000 directories and Runtime.getRuntime().exec("ls -l"); seems to error out after 480 directories or so. The error message I'm getting is is "Error running exec(). Command: [ls, -l] Working Directory: null Environment: null". I'm guessing it's running out of some required system resources or is it? Is there any way to process all directories
