I'm using Eclipse IDE for Java EE Developers.
I created my first android application project, and it's supposed to display the Hello World message, but I run it and get nothing(well, the emulator starts but then nothing), no console output view, no error.If I run it again the console appears(...WARNING: Data partition already in use. Changes will not persist!) and the emulator opens in new window but again nothing
Please tell me what's wrong and how to install and run the app?
after first run(pic1&2), after second run (pic3)
It sounds like the emulator is already running and you are launching a new instance of it... based on the log it has been launched earlier and perhaps it hasn't shut down properly.
-Restart adb as poitroae suggested in an earlier answer.
-If that doesn't help, restart Eclipse.
-If that doesn't help, restart your computer.
If you're still having issues after that, post back.
When you run the app, you will see the .apk file under the "bin" folder.
Reset/Restart the adb server. You should do that over the command line. Make sure that you are in your /android-sdk-root/platform-tools directory.
adb kill-server
adb start-server
wait! As far as i can make out, you're just launching the emulator. Isn't it? there's a green button at the top. (like a "play" button) just press it.
Or right click on the project you want to run, and click on "run as > android application" and watch the emulator play your app.
try to clean your project from project-> clean and also donot forget to wipe user data on android emulator...
here is some good discussion about your problem...
Using Eclipse for androidSDK, when I go to run, I get WARNING: Data partition already in use. Changes will not persist!

Installed android studio latest update and
started a project. But when I press run, emulator is not showing up.
And it say delete *.lock files. But I have already tried. Still couldn't see
the emulator. Please help me.enter image description here
You don't have to completely delete the emulator when this happens. The files to delete should have a ".lock" extension:
You don't need to touch the configuration files.
You can easily find the files location by clicking on the arrow under the Actions tab (in the ADB manager), and selecting "Show on Disk".
On the AVD (Android Virtual Device), edit the device graphic setting from Automatic or Hardware to Software
Go to the down arrow and click on the "Show on Disk" link like the attached image. You will get the list of all files, remove the file "hardware-qemu.ini.lock" and start again.
Try to delete All the .lock files under .android/AVD/emulator_name/.lock,
And right click the emulator wipe data,restart/rerun the emulator.
It's restart the Avd and rebuild the gradle projects.
You can open the task manager and see if there are "qemu-system-x86-64.exe", "adb.exe" and "emulator64-crash-service.exe" processes among the processes, and then you can kill these processes. so you can restart your emulator.
Thank you all for the answers. After trying many ways of your suggestion, I finally decided to uninstall this version and reinstalled the previous archive and it now working fine. I still don't know the reason why. Thanks
Follow this https://stackoverflow.com/a/73287406/11139649 and then delete the Virtual device and create a new device.
This is a screenshot of my DDMS. As you can see there is nothing and I cant find any way to get the devices list or any other functional parts.
I try to reinstall android studio and new sdk but still its not solved. Is there any way to solve this problem?
Thanks
I encountered this problem this afternoon, after half day of annoying work, I solved it at last.
The solution is, just delete *.cfg and monitor-workspace in $HOME/.android/.
Below is how I solved the problem.
There's little information about this problem. I guess it is a rare one.
I have tried several ways. First, reinstall the build tools, simply download and replace the tools directory. But it didn't work. And then I reinstalled the Android Studio, still not work either.
But during the procedure I have found that the ddms must have saved some cache in the computer. So I find the place $HOME/.android/ in this website.
After delete all *.cfg(3 or 4) and monitor-workspace, my ddms works well again.
I guess delete all *.cfg is not necessary, just ddms.cfg. But I'm not sure.
Go to DDMS perspective -> Devices -> View menu(on right corner) -> Reset adb
If still not working, run this commands in command prompt/terminal
adb kill-server
adb start-server
It was broken after latest Android SDK sync using Android Studio. To fix it, launched SDK manager using Eclipse, and installed SDK tools versions 24.01 and 19.1, and removed intermediate results.
I had to right click on "DDMS" (perspective button) and click on reset to make it work.
I am not sure, but you can try Window menu => show preview (select your necessary window view ).
and another try minimum /Maximum window button press
Thanks
Delete the .android directory in user home
I have a DDMS problem in my eclipse while i'm trying to learn android , that there is no files in file explorer in DDMS ..
What is the wrong ??
i tried to restart eclipse but there was no result !
You have to start an emulator first to see the File Explorer.
Before any emulator is started
And after an emulator is started click on the emulator name to see
Edit
If you find that the names of the files are not appearing as they should, try doing as in the following image.Click on the down arrow(as shown in image).And then select reset adb.It should close and restart it.If it doesn't restart itself then manually restart again.If still not working, update android sdk tools from your sdk manager.However i would suggest to try genymotion emulator for once and see if it works.
One more try
Start task manager then go to processes.There stop adb.exe.Now your adb should stop in eclipse.You can then start the adb again to see if it works.Or you can even stop eclipse.exe and then restart eclipse too, to check if it works.
I have a problem with AVD. If I launch it from eclipse, load well but doesn't appear in screen. After that, I try it from terminal but I got the "Segmentation fault" message. Reading another topic I read that it is problem with 20 version of android SDK and to fix it, I should try: .../tools/emulator-arm #nameAVD. It works.
But I still have a problem, I need launch AVD from eclipse to debug applications! Can somebody help me?
Thak you a lot.
Can you tell us a bit more about your system, build, and what version of Android/Eclipse you are using?
if not, try uninstalling and re-installing eclipse, but use the Eclipse Classic version from http://www.eclipse.org/downloads/
then if it doesn't work still, try to delete and redownload the android SDK.
if that still doesn't work then chances are you have something wrong with your system settings
======================
EDIT*** here is a possible TEMPORARY solution..
only use Eclipse to clean/Build your projects, and use your terminal to install your app onto your emulator.
to build an APK without running, right click on your project, go to "Android Tools" and hit "Export Unsigned Package", which will prompt you to store the APK on to some place. Then, open up your AVD emulator and terminal. on your terminal, "cd" into the directory that you saved your APK file (like inside /...../Your Project/bin/) and then run the terminal command "adb install yourAPKfileName.apk"
this will automatically install the newest APK to your emulator and run it. since this process for building is a little slower than usual, i would recommend only building/running when you need to, and always export the APK to the same place, and have your terminal open to the same place, so that when you press "up" on the terminal, it repeats the last command you used :)
First my emulator is too slow to work properly. I'm already frustrated because of it. So I closed that emulator and stated another(by running the application). But now my emulator is not showing in DDMS and every-time I run the application it creates new emulator rather than using existing. So I'm not able to run the application on emulator. If I connect a device then the device is showing in DDMS and working properly, but not my emulator.
And please don't tell me to restart emulator, eclipse etc. Because, already a lot of times I have tried it(even restarting PC), but its useless.
Try running the emulator via the command line with the parameter -verbose, might give you some information on the issue.
I solved this issue by going to wards DDMS-> reset adb..
I understand that the emulator speed is too slow. If You want to start the same emulator, You may choose it explicitly.
If you are using eclipse Right click your project -> Properties-> Run Debug Settings -> Click on your project name -> Edit -> and choose 'Always prompt to pick device' .
So now everytime you build your project, you can choose the same emulator.
Hope this helps!!!
I solved this issue by removing the path to platform-tools from my bashrc file.
In Mac OSx, you need to go Run-> Edit Configuration and you need to tick use the same devices for future
