I have a problem because I am using a tiling window manager, everytime I open an XML file, in Android studio, then these two small windows open op and block my view of the code. I don't know how I can permanently disable the windows/toolbars/view, (or what you call them)
I use Mod+Q to exit them every time I open the XML file, and it is quite tiring, so I am wondering if there is a way to get rid of these useless panels for goods :-)
I already searched alot in the settings of android studio, and I tried to click remove from sidebar and I even found out that you can click Shift+Escape to hide it, but my fingers gets tired from all this extra clicking everytime I enter XML split mode... :-)
Please Help Me - and thanks in advance! :-)
Thanks in advance.
right click on the title, and click on attached side
then left
then you can minimize it
i have found that android studios has never contained any way of 'redoing' a text edit (the opposite of ctrl+z)?
the option exists in the menu/ toolbar but is greyed out. it always has been and it has never functioned.
to test, i have created a clean, empty project, typed in the java class, moved the cursor to elsewhere in the class (incase back to default for some reason prevents it working), typed again.
i then have tested both ctrl+z and manually clicking the undo button, but i am simply NOT ABLE to use the 'redo' option at all. not once since i have been using this IDE.
can ANYONE please explain this behavious and how to get this functionality back? as im finding i often undo one step too many and forget what ive just destroyed.
thanks
Go to File -> Settings -> Keymap
On the right side of the screen, search for "redo" and right-click on the Redo option.
Add a keyboard shortcut (I use ctrl+Y which is pretty standard across applications).
I'm experiencing very interesting problem with my Galaxy S6 Edge phone with marshmallow. When I go to developer options. Instead of a long list of options I get a message of "developer options not available for this user". As far as I know, I don't have any other user (I even don't know how to add a user, to be honest). I saw a couple of people had a similar issue with kitkat but they weren't even able to get the developer options menu item in the settings. I have that developer options item and I actually have it for a while. I haven't done anything special recently and I wonder anyone experienced this before and whether there is a way of fixing this without factory reset.
Finally there are a couple of more symptoms which may/may not be related with this.
Task Switch button at the bottom of screen doesn't work.
The settings button on the notifications panel doesn't work
EDIT : I had to fix the issue by factory reset, I didn't have the chance to try Victor's answer but I am accepting it as the right answer since there are some people who were able to fix their issue
One solution is to run the com.google.android.setupwizard/.SetupWizardTestActivity activity and step through the setup wizard - https://plus.google.com/u/0/+PaulOBrien/posts/8EGNvpY9jQa
A relatively easy way of running that activity is described here: http://forums.androidcentral.com/samsung-galaxy-s7/659407-s7-edge-not-showing-notifications-tray-recent-apps-button-settings-button-dnt-work.html#post5083902
1) Download Nova Launcher & set it as default to replace TouchWiz.
2) Long press on the home screen.
3) Choose Widgets.
4) At the top, under Nova Launcher, scroll to the right & press & hold on Activities and place it somewhere empty on the home screen.
5) Scroll down to Setup Wizard. I saw 2 Setup Wizard options.
6) Under the first Setup Wizard option, I opened it & scrolled down to the 3rd choice which said ".SetupWizardTestActivity". It might be in a different spot for you, but look at the small writing, that's how I saw this one.
7) Select that to create the widget shortcut.
8) Open it. Apparently you're supposed to have a menu to go through and just click through "Next", but there wasn't one for me.
Following the instructions in that forum post fixed the problem on my Note 4.
I was able to fix this by adding and then deleting a new user:
In Settings, go to "Users".
Tap "Add user" and follow the prompts, including "Set up now" to switch to the new user.
Repeat step #1.
Tap your original user to switch back.
Repeat step #1.
Tap the gear icon next to the new user, then tap "Remove user" and follow the prompts.
i am trying to build the android application story book.In this application when user touch the screen of story i want option menu to come out from bottum .i tried to find it out on google but didnt get any reasonable answer.please help me to solve this problem
just call
activity.openOptionsMenu();
I'm new to the Android framework (using Eclipse) and I have a question about debugging. Recently I did this error in an activity:
// The installation button
Button button = (Button) findViewById(R.id.preparationInstallButtonID);
button.setOnClickListener(this);
setContentView(R.layout.preparation);
i.e. I tried to add an onclick-event prior the layout had been rendered. This crashed the program, "Sorry, the application xxx has stopped unexpectedly". Running it again, with debug-mode, Eclipse opens a Debug-window containing "Thread<3> (Suspended)" etc (I'm sure you know which window I'm talking about).
Now, how am I able to extract useful data here? Regarding the problem above I found how to fix it by trial-and-erroring, but let's say I'm not able to do trial-and-error, how can the debug-window help me find the source of the error? It says "exception RuntimeException", but I don't see any pointers as of where in my code the exception occured.
If You want to debug:
Right click left of Your part of code You want to debug (at line number). select Toggle Breakpoint.
You can see small circle beside the line number, that is the breakpoint.
Then, make run configuration, click small arrow beside run icon, and click 'run configurations..'
Click on android application, you will see this dialog window:
Read it, "highlight" this: 'Press new button to create a configuration of the selected type'. Click the New button, above the tab, You will see this dialog:
fill it, browse Your project,
for example, I add Scrumptious project, and launch default activity. Click on Target Tab, choose Your emulator. If You want to run on physical device, click 'Always prompt to pick device'. I run on physical device this time,
for the Common tab, if maybe You want to check Display in favorites menu for 'Debug' or 'Run' option. It is optional. Click apply.
click debug icon - and select your project. If You activate 'Debug' on Display in favorites menu, the project will shown at the debug option menu.
I choose 'Always prompt to pick device', this dialog will shown. I want to run at physical device, so I click the device at the 'Choose a running Android Device', and click 'Ok'. You can also run on emulator. Just click your emulator, and click Ok.
If eclipse give confirmation to open perspective, select Yes
Then, if You want to know what is value of the variable, just put your mouse to the instance of variable, or You can browse at 'Variables' window at Debug perspective.
Use the LogCat this will give you the error messages and everything else that goes on in your testdevice/emulator.
Window -> Show View -> Other -> LogCat
I strongly recommend this tutorial on debugging in general.
http://www.vogella.com/articles/EclipseDebugging/article.html
It takes you through all the features Eclipse offers in that department and is well worth the time.
As far as the particular trick that might've helped, it might have been useful to set a breakpoint (i.e., clicking in the left margin of the code to make one of those blue pins appear). Then, when running in debug, you could stop near where the problem occurred, and step forward, beat by beat, using the "step into," "step forward," and "step return" commands at the top of debug window. While you're stepping around the code in that way, you might have the variables window open, so you could see what things are set in a manner they should be, etc.
Alternatively, you could set a breakpoint on RuntimeException (even one that's caught), by clicking on the Breakpoints window in debug, and then licking the "J!" button (the mouseover text shows "add Java Exception Breakpoint."
The debug view lets you do other cool stuff too, like:
letting you set "watchpoints", so you can see when the application changes relevant fields, etc.
"Drop to frame" so you can start your app in the middle.
Set up step filters, so that "stepping" through I mentioned earlier can be done more efficiently.
Create a detail formatter, a little snippet of java code that formats the output of a field so you can view it more cleanly in the debugger.
And much more!
Again, I recommend the above-referenced tutorial. And welcome to the wonderful world of debugging.
