    for those wondering it seems in android studio 2.0 at it’s current version contains another tab called content_main.xml – this is what you will be using to place your text boxes.

    another thing to note is that a button will be added to your blank layout known as a FAB. You can actually delete this in the activity_main.xml

    hope this helps a few of you. You should also delete the corresponding scripts in the .java file referencing the Floating Action Toolbar.

    If there is a way to load up a previous iteration over the current one that might be better for following along with this tutorial.

    I need some serious help with my app. In my program I have two XML pages that won’t load upon button click. I kid you not when I say all of the coding is correct. There are 8 buttons in the java code and they were all copied and pasted from the same "variable.setOnClickListener (new Button.OnClickListener {});"

    So it makes no sense for the first two not to work, but the other 6 work correctly. All XML layouts have java codes, and all java activities are listed in Android manifest. Also, in redoing the XML layouts that are failing me, I’ve noticed the selected photos I want to use will make the app crash, but work fine with others.

    Again, all coding is correct 100%. No coding is missing and the closest answer I got was that the app ran out of memory space for the app, but I’m pretty sure that’s not it. Btw one of these pages was working flawlessly before I got farther along in developing the app. Could somebody please tell me why this is happening? I have all of my button ref id’s, XML, java, and activities in manifest. Why would only two XML files not work properly when they were all copied from the same code?

    If you’re using Android Studio 2.0 use API 9. If you already started a new project go to build.gradle (Module: app) and change minSdkVersion from 8 to 9, sync (there should be a pop-up asking you to), and use an empty activity. I haven’t found any issues yet just using one SDK higher.

    In case of everything "looks piled" while emulating: If anyone is using a newer Android Studio version, this could be confusing because it uses something called "ContraintLayout", so that blue screen aside of the design screen (looks like blueprint) is the part where those icons, text and such must be specified in position of height and width, if not everything will look piled on the top left side of the screen when doing the emulation. Is hard to explain but, to give a quick hint on the blue design screen you must click on the blue ball thingy that appears in the frame of the objects and drag it to one of the horizontal margins, as-well to one of the vertical margins, specifying height and width.

    HI there Bucky! Big Fan here! I’m going for Web/Software Development. This concept is not working for me. It tells me that "ActionBarActivity" is deprecated, and I get a bunch of errors while running the project. What should I do?

    PLEASE HELP! Whenever I create a new activity, it never looks like the ones you create! Instead I get a double title bar which is really annoying (doesn’t matter which theme I choose), I also have a red message button in the bottom right corner which I don’t know anything about, and sometimes the Hello World is missing. I am using API 23 (Android 6.0).

    Everything I add seems to want to attach itself to all the other components, meaning when I want to move it, it scrambles the entire interface around. How can I disable this annoying a useless feature?

    I have the various widgets listed in a file called ‘content_main.xml’ and not ‘activity_main.xml’. Why is this so? In the video there is no content_main.xml at all….

    I can’t seem to find a blank activity at all on the activity tab. I’ll just accept that there is no longer anything like that on this newer verion (2.1.2). Less someone else knows how to do it

    For people who are seeing this around the time this comment was posted, I used an empty activity. The code was much shorter (only the onCreate) method was on there, and the UI on the phone had a top bar, right under the status bar with the name of the project.
