I am developing Android app in eclipse with Android SDK 2.3, but i am unable to see the errors like we see in java or .net, there are no run time errors tracing, if there is some error i have to place alerts there to check it, where as compiler does not place any error in its window. Its quite strange that it gives compile time error but no run time error. Please help.
Thanks

Go to Window->Show View->Other.., and select Android->LogCat. This is the running system trace. I believe this is what you are looking for.
So first thing about android is, you will not be able to look your output details in console as your java or .net shows. As you might know emulator is what is considered to be your output window. And in order to find compile time errors eclipse makes it easy by highlighting your mistakes instantly. And as you have asked for, to look at your runtime errors android uses a special view called Logcat. This is were you will be listed out with all the runtime details of android. And as you have said that you are not able to view even System.out.println messages not being viewed, you might find it a bit strange but actually android does print these mesages in Logcat for you. So as the user sparkymat has suggested follow the steps and you are done.

I am using Android Studio 4.1.1. windows 7. I write in Java. I noticed this feature of the program. Changing something in code, layout or resources. I run the program and see that my changes have not appeared! First comes the thought that I was wrong somewhere. I start looking for an error. I don’t find it. I run the program again and it already works as it should. Now I'm used to it. The larger the program, the more often this happens. To be sure of the result, you have to run the program twice each time, because I'm not sure if this time all the changes took effect. It is very uncomfortable. Tell me why this is happening and how to solve this problem.
In this video, Venkat Subramaniam is running simple java file and he is able to see the result on screen as the given below image. Does anybody know which tool he is using ?
Its actually a wonderful feature, but unfortunately this only work for Textmate.
Here you could find how to set it up for Textmate: https://www.ivonet.nl/2017/11/07/textmate-get-run-output-as-tooltip/
For IntelliJ IDEA there no such thing. But, a one guy has tried to do it in InteliJ Idea with a plugin which is available at https://github.com/jcraane/intellij-tooltip-runner. But, it is outdated and not working in recent releases.
I have recently started learning android development, and I just built an app that changes color and text based on pushing buttons and gestures. It ran fine on my phone (Yay!), but then on my second run, an error occurred. When hitting the "run" button, an edit configurations window opened up:
I also noticed, that on the side where my project tree should be is this instead:
I don't think there is an issue in the code because it was running fine before, but I would be happy to post the code if needed.

I dont know if this was the reason, but i'll include this anyway, I tried changing the name of my project, but it wouldn't work, but I changed it back. I included this in my question because that's literally the only thing I did before this error occured.
Thank you so much for helping out a fellow programmer, I really appreciate it. I have been looking at many other forums (for some hours) about this topic, but still couldn't trouble shoot this problem. It seems kind of odd that it was working first, and then it just randomly stopped working. I cant wait for your response!
Here is the dropdown for Module:
As you can see, that is the only option.
Are you sure you are opening the project as android gradle project ?
Try to import the program not open it
I am having problems with debugging my code. One of my AsyncTasks throws a RuntimeException, but I don't know which line in my code is responsible for this. Since I am new to Eclipse and Java in general, all of this is rather confusing to me.
Eclipse's debugging window shows me that my AsyncTask has been suspended because of a RuntimeException. Below that, there are three lines which point out certain lines of code. However, those lines do not exist in my code which is why I do not know what causes my application to crash. Am I missing something essential about debugging in Java / Android?
These are the three lines which I am given, by the way:
ThreadPoolExecutor.runWorker(ThreadPoolExecutor$Worker) line: 1086
ThreadPoolExecutor$Worker.run() line: 561
Thread.run() line: 1096
How am I supposed to work with that? Help would be greatly appreciated.
in the ddms you can get the message related to the error, warning or other type of messages into the logcat window if you can't able to find the logcat in the ddms then go to the menu Window->Show View->logcat click on that and you'll be able to see the message now in the same ddms you also get the device window from that select the device for you can able to debug or get the message from that device into the logcat.
now check this way you can find your error detail into this logcat details
You're best using the logcat - this will show the stacktrace and the error raised. I've never had great success stepping through the code in DDMS but with the errrors shown in the logcat it's normally pretty easy to work out why the error was raised.
See Pratik's answer for opening the logcat if it isn't visible within Eclipse.
Rajeev got it right - when you set a breakpoint on an exception, the debugger will break on the line that throws it, not the line that catches it. In this way, you can see what is causing the exception.
For all of you android devs out there that have the Android simulator running on your comp, you know that there are a few built in apps that are already installed on your 'phone'. I had an idea for an app that would utilize a function that is already being done in the spare parts app that comes already installed.
I went on to the android developer site, dug through the source code files, and found the spare parts app, and am now trying to set it up so that running it from eclipse on my machine actually runs the app in the simulator. In other words, I want to be able to make changes to and adjust some of the things in that app for my own needs. But it won't compile, because of a number of different errors.
How do I get that source code running on my local machine? Is there some special trick that I just dont know about? I thought that if I could get the source code than the rest would be easy, but it isn't being too easy.
Not knowing what the error is, it is hard to say. But there are some tricks. First, you want the entire spare parts app in Eclipse, not just the code you are interested in running. Second, right click on your project, and go down to the "Android Tools" menu. Then click on "Fix Project Properties". Do a clean on your project and hopefully that will help.
