Android Debugging with Logcat and Emulator. Is it possible?

Question

This is pretty simple: I'm using NetBeans on Linux with Android emulator 1.6. I have Logcat on my android phone, but the process of getting the messages to somewhere readable isn't smooth at all.

Can someone tell me how to get Logcat running on the emulator? Is there anything I can do to see debug messages other then having to copy the apk to my phone and testing it?

Thanks in advance!

You have a few options for viewing the debug log output, assuming you have the SDK installed and your command path set up correctly:

1. Type adb logcat. The log output from the connected device or running emulator will appear. I usually prefer adb logcat -v time to see the time stamps.

2. Type ddms. This launches the stand-alone version of DDMS. It has a logcat display at the bottom.

3. Install the ADT extension for Eclipse, and open the logcat view. (Since you're using NetBeans I assume this isn't what you want to do, but I'm mentioning it for completeness.)

In all cases, the interaction is the same whether you're using a physical device or software emulator, because the ADB daemon conceals the details. Whatever you're doing for the device is also expected to work for the emulator.

If you have a device and emulator connected simultaneously, you can use adb -e logcat for the emulator and adb -d logcat for the device. From stand-alone DDMS or Eclipse, just pick the device or emulator from the pop-up menu.

Solution 2

If you have setup nbandroid you can find the adb logcat viewer in netbeans under: Window -> Output -> ADB Log

--edit Just followed up on the post above and started using C:\Program Files (x86)\Android\android-sdk-windows\tools\ddms which is alot better then the one in netbeans.

Solution 3

The SDK comes with a handy tool called ddms it should be in the tools folder of the SDK. At the moment an Emulator is running, or a mobile phone is connected to your machine it should show up in ddms and you can see all the log output in ddms.

The process is quite easy using Eclipse, but I don't know whether Eclipse is available for Linux. If it is and you're willing to switch to using it, see this other question for details on how to set up debugging. stackoverflow.com/questions/2552568/…

Eclipse IS available for Linux. I might switch... we'll see.

Just start ddms from your terminal you should see everything else

Now - at SDK for Android 4.2 - the command for standalone monitor is: ...\android-sdk\tools\monitor For local instation on Windows the full comand is: %LOCALAPPDATA%\Android\android-sdk\tools\monitor.bat

To clarify the above comment, the device monitor is meant as a replacement for standalone ddms. (running ddms on the command line displays The standalone version of DDMS is deprecated. Please use Android Device Monitor (tools/monitor) instead.) In Linux, running monitor should be sufficient to run the device monitor.

Caution: DDMS has been officially deprecated (and more recently removed) in Android Studio ≥ 3.0. Use Android Profiler instead.
