I am trying to develop an android app. But when I create another Activity, the design page displays Exception raised during rendering: android.graphics.drawable.VectorDrawable_Delegate.nCreateTreeFromCopy(JJ)J.
If I understood you correctly, you should change the preview API level from version 24 to 23, attached id a screenshot of same issue, if is then solve as above.
If I did not get you, then please clarify. Good luck.

I just started my first Android Studio project and I already come with a problem :)
I search on google for the answer but didn't find my problem.
So I need your help please ^^
I download the last version of Android Studio, create a project with an Empty Activity and I came up with this
As you can see my ConstraintLayout is really small and I just can't work with this.
I didn't touch anything on the project. Just to be sure I create 3 projects that have the same issue and redownload 4 time Android Studio.
On the virtual Devices, it looks correct throw: Screenshot
I put the XML code just in case it can help
xmlcode
Hope I was clear and sorry for my English ;)
EDIT: For some reason, the constraint layout fit correctly on the watch screen, but I don't want to create a watch app x) screenshot_watchview
Ok so I have finally find the problem ! I'm so happy right now :D
The problem was the AppTheme theme that I use, I switch it with the DeviceDefault theme. I don't know why this theme was causing problem but now it work and I can finally work on my first Android App !
If you are using the supportLibrary 28+ then this thing happened to me too.
and when I change the support lib version to the 27, it works.
Maybe this is a possible bug in the support library 28+.
Changing the AppTheme works like a charm if you want to stick with the support library 28+ But if you still don't want to so Try using the support library below 28.
I hope someone can help me with my Android Studio preview. I can't get the normal cell phone preview, but instead I get a rendering problem. I am not sure how to fix this and can't find any good solutions that seem to work.
Which layout should I pick? I have provided a screenshot of the problem:
Thanks in advance!
This is only a warning from Google maps fragment, you can ignore it clicking 'Do not warn about...'

I'm trying to learn App Development using Youtube tutorials. I did exactly as it was shown in video, but after 2 or 3 times restarting the Android Studio, it is not showing the workspace. This is what was coming on screen, The error
Thanks in advance...
I didn't exactly understand what was wrong, but when I changed from API 23 to API 19, it started showing the screen.
I am a complete newbie who has just about started android app. development using Xamarin Forms and VS2012. Only about 20-21 days of exposure I have got. I am trying to learn along the way through writing an imaginary practice app. But there are some errors I am getting. You can see them in the picture.

Can someone direct me what exactly it is saying and what I need to do in order to rectify them?Is there something wrong with the installation/environment or like some update? Or is it something else? What's with the "unzipping failed" message?
Some one kindly help me out here please. Facing great deal of difficulty in tackling this.
Many Thanks in advance.
As the error message says (see the third error message ), you need to install the "Android Support Repository" from the Android SDK manager.
The errors are telling you that Xamarin is looking for the support library, but that it cannot find the support library and thus the build failed.

Just an update I want to post:
I went about reproducing this scenario: creating a new project, do some primary simple code, add 1,2 layouts et all. When I build the new project, these 9 errors don't appear. This is strange to me. Because: this is exactly what had happened to my main work also. These errors were not there. Something, somewhere happened along the line, due to which they started appearing suddenly; out of the blue. I remember, I had updated Xamarin version, also just added some packages like JSON.Net and it is only after that this error list appeared. Not before that, if I remember correctly. Which is weird to me. If you try to recreate by creating a brand new project these 9 errors won't appear. I tried recreating this twice; no errors.
Yes, I'm manually downloading the zip file. Hopefully this makes the compiler happy. I'll keep posted about the updates.
Thanks All!
My basic functionality and everything are working just fine but there is one thing that is troubling me.
Whenever I use an EditText field, the XML fails to render and nothing is displayed. The problem doesn't occur with any other field. I've been getting the following error:
Exception raised during rendering: java.util.Locale.toLanguageTag()Ljava/lang/String
Does anyone else face this issue?
It may be an issue with the API you have set in Eclipse.
If it is set to the Android Wear it may cause this problem.
In the xml Graphic Layout window, look for the android symbol in the top right corner.
There is a drop down arrow, which will list all of the API versions you can use. Check that it is now set to API 20(4.4W.2). You may need to change it to API 19 or API 20 L.
Hope that helps
In my case I was rendering for Android Wear , and that was causing the problem , setting it to API19 in design view , solved it
Clean Your Project and Rebuild.
2.Close Eclipse And Restart again.
3.its Working fine.
