shmemBase_attach failed when connecting to Android device

I'm trying to hook up jdb on my computer to a process (any process really) on my Android device, but it doesn't work at all. So the commands I used are straight off the Google ADB Documentation. First I do adb forward tcp:3456 jdwp:pid Then after that I try to use jdb to try to hook up jdb -attach emulatorIP:3456 But I get the following error: java.io.IOException: shmemBase_attach failed: The system cannot find the file specified at com.sun.tools.jdi.SharedMemoryTransportService.attach0(Native Method) at com.sun.tools.jdi.SharedMemoryTransportService.attach(SharedMemoryTransportService.java

How to script the java debugger command-line tool (jdb)?

由 不问归期 提交于 2019-12-01 01:28:57
How can I drive the debugging session with some scripting language like ruby? Is there any easier options than using Expect or some similar module with a scripting language? You may be able to use JRuby to drive your own debugger via the JPDA API. Check out jdiscript ; it's a thin scripting frontend for the JDI that can be used with Java, JRuby, or any other jvm language. 来源： https://stackoverflow.com/questions/630044/how-to-script-the-java-debugger-command-line-tool-jdb

Attach jdb on uncaught exception

由 隐身守侯 提交于 2019-11-30 10:01:41
So, I am starting a Java program as below java -agentlib:jdwp=transport=dt_socket,address=8000, server=y,suspend=n MyClass I then manually attach a debugger as below jdb -attach 8000 I would like to know if there is anyway for me to set up jdb so that it automatically attaches to the running process (only) in the case of an uncaught exception? The reason being that I would like to avoid the overhead of the debugger until an uncaught exception arises. But the problem I face now is that if the debugger is not attached, then the JVM aborts once an uncaught exception arises. EDIT: From the Oracle

Android with jdb confusion using waitForDebugger

由 给你一囗甜甜゛ 提交于 2019-11-29 08:20:27
I'd like to debug my Android application on my device (Nexus One - not the emulator) using the command line. I'm confused at how to set a breakpoint using jdb in combination with android.os.Debug.waitForDebugger . Say I put the following code in my main activity onCreate : public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); android.os.Debug.waitForDebugger(); int j = 10; int r = j; } Using ddms I can see that my application is waiting for the debugger (red bug icon) when I start it. However, I don't understand how to set a
