Help me!
I need the source code to force stop an Android application programmatically.
I already tried
Process.killProcess(int pid))
but it didn't work
Thank You.
Three ways to stop a process from java
1.kill directly
Process.killProcess(Process.myPid());
2.send SIG_KILL
Process.sendSignal(Process.myPid(), Process.SIGNAL_KILL);
3.the unfriendly way, terminate the vm
System.exit(0);

I have created a java application to connect to a MySQL database. Once through the program install creator, I created a .exe .
This executable runs, and the first form is login. When he tries to access the database to confirm the details of login gives this error.
java.lang.NullPointerException
Someone can help me solve this? The path is correct because if run the .jar the application runs normally.
I apologize for the inconvenience.

Only have this to try to explain better my question :S
I'm so sorry... I'm running an executable version from my java application.
We will need more information than this, some things that you can provide that would be helpful are...
Your packaging tool (what you use to get from jar to exe)
Code
A stack trace

I am currently writing a Java Application, that needs to filter the name of the Program whichs UI is front. Sorry for my bad english.
So let's say the Java App is running in Background and I open Windows -> Games -> Minesweeper then i want the App to only tell me "Active: Minesweeper". Without any additional information. Just the name "Minesweeper"
I already tried using JavaNativeAccess but I'm still unfamiliar with it.
Thanks you all in advance

I execute jar file on double click but it stops running as soon as I log out. What I have to do to make it keep going unless I shut down system?
It might be possible that, in your jar file it is written that on logout system.exit(0) or any other logic will be called.

How to get pid of android application without using adb shell?
(2 answers)
Closed 6 years ago.
Is there a way within a java app that's running under Android to determine that app's process ID ("PID")?
The reason I want this is that I am writing an app which reads and processes lines from logcat, and I want to be able to ignore all logcat lines that have been written by this app, itself.
I know I can do this by using a unique tag for my app in all the Log.*() calls and then ignoring logcat lines with this tag, but it seems to me that it would be cleaner if I could simply ignore all logcat lines which have been written by my own app's PID.
I've searched, but I couldn't find anything which explains how to determine the PID of a running Android app, from within that app, itself.
Thanks in advance for any suggestions or pointers to docs.
You're looking for this, I think:
int id = android.os.Process.myPid();

So I have a java program of a game. I want to have a different program and when you click on a button there that java program closes and starts the program with the game. But I have no idea how I can do that, so can anyone help me?
Using ProcessBuilder.The following is a reference,maybe not work.
ProcessBuilder pb=new ProcessBuilder("java","-jar","Test3.jar");
pb.directory(new File("F:\\dist"));
Map<String,String> map=pb.environment();
Process p=pb.start();
Create a runnable jar.
call the runnable jar on button click.
Exit from the current program.
