For the first VM, DDMS listens for a debugger on port 8600, the next on 8601, and so on. When a debugger connects to one of these ports, all traffic is forwarded between the debugger and the associated VM. When a debugger connects to this base port, all traffic is forwarded to the VM currently selected in DDMS, so this is typically where you debugger should connect.įor more information on port-forwarding with DDMS, Debugging can then process like any remote debugging session.ĭDMS also opens another local port, the DDMS “base port” (8700, by default), upon which it also listens for a debugger. Preferences are saved to ”$HOME/.ddmsrc".ĭebugging an application in the Dalvik VM should work the same as it does You can set a number of DDMS preferences in File > Preferences. However, when single-stepping out of synchronized code, the “current line"Ĭursor may jump to the last line in the method for one step. The left side of the Debug Monitor shows each emulator/device currently found, with a list ofĪll the VMs currently running within each. Use this list to find and attach to the VM VMs are identified by the package name of the application it hosts. Running the activity(ies) that you want to debug. List is a “debugger pass-through” port (in the right-most column). If you connect your debugger to one of the the ports listed, you Will be connected to the corresponding VM on the device. (Notice, as you select a VM in the list, the listed port includes 8700.) However, when usingĭDMS, you need only connect to port 8700, as DDMS forwards all traffic here to theĬurrently selected VM. This way, there’s no need to reconfigure the debugger’s port each time you switch between VMs. (or you select this option in the developer When an application running on the device calls waitForDebugger() Options), a red icon will be shown next to the client name, while it waits for theĭebugger to attach to the VM.
When a debugger is connected, the icon will turn green. If you see a crossed-out bug icon, this means that the DDMS was unable to complete aĬonnection between the debugger and the VM because it was unable to open the VM’s local port. If you see a question mark in place of an application package, this means that, If you see this for all VMs on the device, it is likely because you have another instance ofĭDMS running (this includes the Eclipse plugin).
