I have android packages for 4.4, 5 and 6 installed in my android sdk. When i reduce the API level from 23 to 19(android 4.4). i get the following error:
------Rendering problems----
The graphics preview in the layout editor may not be accurate
-porterDuff Color filters are not supported
please how can solve this
I have been able to solve this by clicking the refresh button close to the mobile phone image. If this doesn't work, then consider reinstalling android studio.

I have a new set up visual studio 2015 (updated) in a new laptop and I am having a problem with my project from an old laptop. I don't know why my device and 2 emulators are listed on Unsupported Devices in this new set up visual studio.
Minimum Android version is set to android 4.1 jelly bean
target is set to compile using SDK version
Compile using nougat 7.0/also tried to marshmallow 6.0
I have my phone nougat 7.0 and 2 emulators 6.0 but I don't know why from my copied project from old laptop says API Level is less than the minimum Android version defined in the manifest file
Already tried to delete bin and obj folders. Tried to set min, target and compile with other combinations but no luck to solve this issue.
What can I do with this old project in my new VS 2015 set up? My new projects don't have a problem at all.
I ran into the same problem, there's a "minimun android version" dropdown under the Android Manifest tab in the project settings. Changing it there made my emulator pop up again. Got the idea by reading this: https://developer.xamarin.com/guides/android/application_fundamentals/understanding_android_api_levels/
Edit: I'm using Visual Studio 2017 Community
I found the answer for this. I have found out that it is because of API 24 and up from my SDK manager. I deleted those API and voila ! Unsupported devices are gone and back to normal . I don't know if it is because of the project built from another laptop only having API 23 below and when I transferred it to a my laptop with Nougat and Oreo API, unsupported devices happened. Hope it give helps to other coders.
When I try to run the default 'Hello world' activity or blank activity I get the following error:
minSdk(API 23, N preview) != deviceSdk(API 23)
I'm using Android Studio 2.0 and I have tried multiple Virtual Devices. (Nexus 4, 5, 6P) But they all gave the same error. I updated and installed a lot of files on the SDK manager. I have no clue what the problem is. Again I haven't changed the file, it is just the standard Blank activity. I just installed Android Studio and I'm new in this area. I hope it's a common mistake or error. Can someone help me out please? Thanks!
You appear to have set up the project to use the N Developer Preview, which means that it will only run on N Developer Preview devices and emulators.
Assuming that this is a typical Android Studio project, open app/build.gradle. In there, you will see minSdkVersion, targetSdkVersion, and compileSdkVersion. Probably all are set to 'N'. If that is not what you want, change them to something else (e.g., 23).
I start New Android project "Blank Activity" in Android Studio with Android 4.0
but I noticed that for rendering used API 23 (Android 6.0)
and if I click to use Android 4.0 (4.4W.2, 4.4.2, 4.3.1, 4.2.2, 4.0.3), i receive the following error:
Rendering Problems
The graphics preview in the layout editor may not be accurate:
- PorterDuff Color Filter are not supported. (Igrone for this session)
Tell me please how to fix this problem and why it happens.
Or it is quite normal that for rendering the project that uses the Android 4.0 uses Android 6.0 ?
I use Android Studio 1.5.1 141.2456560 and Java SE Development Kit 1.7.0_79
I think I found the answer to this question

The application for a specific API will have forward compatibility with future releases. Platform SDK uses the target value if the near future platforms will be expected a significant change in behavior. This ensures that the application will not break when you upgrade a user's phone.
It turns out that it does not matter as what API to use for rendering the project. If you created your project for the minimum Android 4.0 platform and rendering in Android Studio using Android 6.0 then it is quite normal.
Ok, so i have been using eclipse for my android development but then i noticed that the eclipse IDE gave me a lot of errors and i researched online and found that Android Studio was worth a shot. So, i downloaded android studio yesterday and then created a test application. The Target SDK was 15 and i was using Android 2.0 Froyo to test my application since it loads faster. Now, when i run my app, i get that annoying message and i have no clue how to fix it. Please guide me through the steps of fixing it. Thanks a lot
The minSdkVersion in your project -- whether from your code or from a library -- is higher than the API level of the device or emulator on which you are trying to run your app. Either:
Adjust your minSdkVersion, or
Use a device or emulator that is capable of running Android at the level specified by your minSdkVersion
I have installed Android API version 21 (lollipop), since i have been trying to set up an AVD . There is no "new" button,instead there is a "Create" option . then no matter what configuration i set , AVD manager fails to create the emulator.I have checked for updates.No issue with OK button . I tried a lot of things ... Any clue ??
Android 5.0 Lollipop has not been released by far. But it will be at 12th Nov at America time zone. So, the IDE downloaded from Android Developer site is the preview version. And, I tried it as you, but, I realized it was incomplete. And some features were unavailable. So, I have been waiting for the release version, Android 5.0 Lollipop and its IDE bundled with ADT and Eclipse. Hopefully, this will help.
