Render problem in android studio

I've re-downloaded Studio (again) and I've added every SDK update using administrator sign in but I still seem only to be able to use the AppTheme or AppTheme,NoActionBar. Everything else gives me the following. Any input would be appectiated! (Material Light here.. Nexus 4, API23): it says "Rendering Problems. Missing Styles. Is the correct theme chosen for this layout? Use the Them combo box above the layout to choose a different layout, or fix the theme style references. NOTE: One or more layouts are missing the layout_width or layout_height attributes. These are required in most layouts." It gives a link to Automatically add all missing attributes, but when I click on it, nothing happens. It also has a link t Copy stack to clipboard, which gives the following: java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library. at android.support.design.widget.ThemeUtils.checkAppCompatTheme(ThemeUtils.java:34) at android.support.design.widget.CoordinatorLayout.(CoordinatorLayout.java:178) at android.support.design.widget.CoordinatorLayout.(CoordinatorLayout.java:172) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:422) at org.jetbrains.andr...

The Problems panel in Android Studio is a centralized and shared issue panel for all design tools, such as Compose Preview, Layout Editor, and Layout Validation. To view the tool window, navigate to View> Tool Windows> Problems. Figure 1. You can view all the issues for your design tools in a shared issue panel. From the Problems toolbar, you can see the View Options, such as Severity Filter and Order, the Editor Preview, and suggestions for Quick Fix. Figure 2. The Problems panel has the following view options that you can sort by either severity or name: Show Warning, Show Weak Warning, Show Server Problem, Show Typo, Show Visual Lint. Individual issue details are displayed in the Issue Details pane in the Editor Preview. Each issue can be displayed in the built-in editor so that you can preview the code. View issues with visual lint Android Studio automatically checks for visual lint issues for your layouts that are written in Views. When you open Layout Validation, you can see all your layouts render in multiple device sizes. All visual issues, including background visual linting, appear in the Problems panel. Visual linting rules look not only at the current file, but also at the versions of the same layout with different qualifiers–for example, landscape or sw600, if they exist when performing the analysis. Figure 3. Visual lint issues are displayed in the Problems panel. Content and code samples on this page are subject to the licenses described in the Last updated ...

This page contains guidance for troubleshooting common issues and configuration problems in Android Studio. High-density displays As of version 1.5, Android Studio provides support for high-density displays (like HiDPI and Retina monitors) on all platforms. Scaling factor settings Android Studio determines the scaling factor for your display as follows: Mac For Retina displays, UI elements are scaled by a factor of 200% and images are rendered in high resolution. There should be no blurriness due to scaling, even in multi-monitor configurations. Note that there is no support for scaling factors other than 100% (for non-Retina displays) and 200% (for Retina displays). Windows Android Studio uses the primary display's DPI settings to determine the scaling factor of UI elements. For images, if the scaling factor is less than 150%, normal resolution images are scaled up. If the scaling factor is greater than 150%, high resolution images are scaled appropriately. Linux Android Studio determines the scaling factor by looking at the "Text Scaling Factor," then at the XWindow system DPI Setting. A DPI setting of 96 corresponds to a scaling factor of 100% (no scaling), and a DPI setting of 192 corresponds to a scaling factor of 200% (the size of UI elements is doubled). Android Studio currently supports DPI settings between 96 (100% scaling) and 288 (300% scaling). If Android Studio does not detect the correct system DPI on your Linux or Windows machine, you can set it manually by ...

When you picture a workstation, it's often a tower PC, something bulky to accommodate the components and cooling you need to edit video, render 3D images or process thousands of photos. But the recently refreshed Mac Studio (starting at $1,999, $6,799.99 as tested), offers the power of a workstation in a tiny, quiet box that fits easily on your desk. The Studio also happens to be the home of the M2 Ultra, Apple's most powerful chip (the lower-end configurations come with M2 Max). It's rare that we test pre-built workstations, but when we got the opportunity to test the Mac Studio we took it as a chance to get a sense of what the 24-core CPU and 76-core GPU can do. The short take: If you're a Mac user that needs a lot of power, we think you're going to come away impressed. The M2 Ultra delivers some significant improvements over Apple's other chips. But if you need expansion, the Mac Studio may not fit your bill, as it's not upgradeable. Those users may want to consider the Mac Pro, which also comes equipped with the M2 Ultra, but in a bigger case that includes PCIe slots to add sound cards, storage cards, and more. Design of the Mac Studio 2023 • Apple Mac Studio (Silver) at Best Buy for $1,799 As far as workstation-class machines go, the Mac Studio is petite. It's a desktop that has no problem fitting on, well, a desktop, even under a monitor. It tucks in nicely under the Mac Studio display, and that should be similar under many other screens. It's an aluminum block with ...

Hi, I am trying to learn Android development. I am learning from developer.android.com/courses And have problems with @Preview rendering. Every time I change something in code (even if I just added new line) preview try to automatically Build and Refresh, but every time it fails.
