Hello people of Stack Overflow!
I've been trying to create my first app for a while now using eclipse.
I understand how to create the layout in XML. I understand Java enough to do build simple java applications and work with packages and such.
I've been following this tutorial series and have come to a point where i need to test the app.

** sorry: not enough rep to make three links **
This is where the trouble is - testing. The emulator from AVD doesn't show my app's icon anywhere in the menu. I have also tried Genymotion, and the same issue occurs.
As far as I know, all of the paths and uri's are correct to link everything up, but it just won't
show.
The directory structure containing AVD Manager and SDK Manager are both located directly on the C drive.
My eclipse workspace is under my user's folder.
When I go to run it as an android application, the option doesn't appear sometimes, but once I clean the project, the button appears again.
Below are some screen-captures I took and uploaded to imgur. I hope somebody can help me.

Thanks for the attention! :)
I'm willing to try Android Studio as well, but eclipse I am accustomed to from school.
I don't know if it whatcmade the problem but you dont have any setContentView there.
Your app will not show any xmlfile or even a view.
Make sense that your app will not show anything but i dont think thatvit will cause it to disapear (if icunderstood correctly)
Try fix it and if it does not work please show me your androidManifest.xml file

Prerequisites: Got a working app from a friend who needs some changes made. They were outsourcing and now want to internally manage it.
I come from a web and game dev background, so Android/IOS development is new to me, but a lot of the principles seem to be the same.
I got the project onto my device, installed all of the dependencies, and fixed all of the file paths.
The app successfully builds, and I have my virtual Android device running it great!
However, my buddy wants some really simple layout changes, and for the life of me, I can't find where to just edit the home screen layout. I was trying to solve my issue from a web dev approach, by grepping where the logo screen is used in the app, but those files seem to just load a white "background" layer, and not the entire composed page?
I'm missing something really silly here, and I just want to ask a real person on here, instead of digging through documentation and trying to word a condensed question in a Google search.
Here are my condensed questions: How can I just edit the home screen of my app in Android Studio? Where can I find the full home page file to view the entire layout, and not just a fragment?
Edit: The app also utilizes the Flutter SDK, which may explain why I have been having trouble with layout edits. I'm going to look at it again after work today, and hopefully answer my own question. I appreciate the help so far!
Edit 2: After going back to the app with a different approach, I found out my project had defaulted to the "android" sub folder of my master, and wasn't showing any of the Flutter .dart documents. After going up one folder directory, I was finally able to access that Main.Dart file with the display information.
I was able to mount it for inspection, but its saying my emulated device isn't supported. I need to look at it when I have time tonight, and may need to ask a separate question for it. I have my project sdk set to Android 33, and my virtual device is set to Android version 33. I searched around Stack, with a few people with reporting similar issues. I tried following their solutions, but it didn't seem to work.
As the title states I am making an app with android studio. I recently installed git as well in order to interface with GitHub. For some reason whenever I change the layout on the layout editor, or type more than 3 characters of code the git terminal opens up multiple windows, then they disappear, and I get no errors of any kind. It repeats indefinitely and I am really unable to get any work done because of it. Has anyone seen anything like this before and if so I would love any help I could get. Thank you! I tried to make this as detailed as possible hopefully it isn't too broad.
I'm trying to see the contents of a database I'm using through the execution of my program via DDMS. I've looked at lot of questions on here that explain how it's done. My understanding relies on the fact that on clicking Tools--> Android--> Android Device Monitor, there is a change in perspective however nothing of the sort happens when I do the above. In fact, there seems to be no indication at all, that I selected the Android Device Monitor. Could someone please point me in the right direction of finding out what could be wrong?
Going off what #will421 said in the comments, I ran monitor.bat and the typed out monitor in the console (Both needed to be done.) and then I was prompted to enter my sdk path. What tripped me up was the fact that I had two folders labelled sdk and sdk1 so choosing the right one is important. To view the contents of the dtatabase, I just followed along with the great answer at View contents of database file in Android Studio
I'm a .NET developer but I like JAVA so in my free time I play around with that. I don't normally use Eclipse but I installed the ADT eclipse plugin and Andriod SDK and I started learning and I made a new project with a TableLayout and it kinda looks good, and it runs ok on the emulator.
However... there a few things that drive me absolutely catatonic and perhaps I am doing something wrong so please help me out.
Firstly, if I change the main.xml file in whatever way, even by adding what is supposedly a correct parameter, it will start freaking out and will generate an error that just says "error" without specifying what that is, it will then generate a main.out.xml and then report an error that the main.out.xml is empty. It later won't let me delete that and will start generating a main.out.out.xml and so forth, even after I correct that original xml that caused the error.
The only way to get things going is to delete the bin folder, restart Eclipse, delete all the out xml files and then sometimes it will run the application or some other times it will start generating those 'out' files again and the loop goes on.
That way it takes hours to run a simple app even one without errors that used to run before.
Surely that was NOT how they intended it to work, is it??
Also.. there is no "Rebuild" button that will flush all files out automatically, or is it hidden somewhere? I am tired of manually deleting those automatically generated files and the build folder and all those out.xml files.
Also, while I'm at it, I also want to point out that the designer view sometimes disappears and there is nothing on earth that will bring it back, the only way is to create a new project and copy the main.xml to it and then it shows up again. Another bug?
I have the latest eclipse version:
Version: Indigo Service Release 2
Build id: 20120216-1857
If you have any clues how to get this to work, I will appreciate it!
Many thanks in advance
When you click the Run button with an XML file selected, Eclipse is running an XSL Transformation on that XML and producing the .out.xml file as the result. This is a feature of the Eclipse Web Tools feature, which you'll have if you installed the Eclipse for Java EE Developers package (it may be included in other packages, too).
As others have said above in the comments, to run your Android app, select the Project, right-click, and choose Run As > Android App. Once you've done that once, it will create a Launch Configuration that you can launch from the Run or Debug toolbar buttons (pressing the small down-arrow on the Run or Debug buttons brings up a list of Launch Configurations that you can select from, as well as an option to manage them).
There is a Preference that will make Eclipse always launch the last thing you ran or debugged, instead of trying to be smart about what is currently selected. Open the Preferences and navigate to Run/Debug > Launching; there you'll find the option under Launch Operation at the bottom of the window.
I've been working in Eclipse programming for Android for about a year now. I suddenly have an enormous problem. Here is the error:
"Content Assist" did not complete
normally. Please see the log for more
information.
java.lang.NullPointerException
I go to Help>About Eclipse SDK>Installation Details>Configuration>View Error Log and it is nothing but a blank page. No errors at all.
I tried researching online. The most relevant pages I could find are http://forums.adobe.com/thread/455543 and http://www.themorphicgroup.com/blog/2009/10/27/content-assist-did-not-complete-normally/ and http://www.airtightinteractive.com/2010/01/fix-for-flash-builder-content-assist-did-not-complete-normally/ . All of these pages say to close FB, delete the .metadata folder,restart FB, import/export some SWC file, and/or delete some file with "flexbuilder" in it's name. None of these work and I see nothing on my whole machine with any of "Flash Builder", "FB", "flex", or "flexbuilder" in it's name.
As a desperate last resort I deleted all traces of Eclipse, Android, Adobe anything, and Java from my machine.
Absolutely no difference what-so-ever. Besides exhaustion and heartache for me.
The content assist features seem to work fine in java files (for now anyway). It seems that only .xml files are affected.
What can I do to resolve or work around this issue?
Make sure the correct editor is opening the xml files. I have aptana and some other plugins that support xml files. Right click the file in project explorer and select open with, then select Android Xml Editor and see if you have completion.
I dont know if that is the exact name, because my eclipse just went south and wont even open :)
Right clicking the file and opening it specifically with Android Layout Editor is what solved the problem for me. Eclipse will continue to open it up with that editor after choosing that editor.
Uninstalling and re-installing the Android Developement Tools Plugin for eclipse at least partyl fixed the problem for me.
Strangely it worked best when completely uninstalling the plugin!?
