Which minimum android version is supported by flutter?
Do some plugins have any effect on which version is not supported?
I tried to run my flutter app on an android emulator, but with the version android 16 it doesn't work and the app crashes. Do I have to change the compile version in some config files or why doesn't it work?
Flutter support 16. But to run app on Android emulator, use over 19.

From Flutters FAQ
flutter.dev/docs/resources/faq#what-devices-and-os-versions-does-flutter-run-on
Mobile operating systems: Android Jelly Bean, v16, 4.1.x or newer, and
iOS 8 or newer.
Mobile hardware: iOS devices (iPhone 4S or newer) and ARM Android
devices.
Note Flutter currently does not support building for x86 Android
(issue #9253) directly, however apps built for ARMv7 or ARM64 run fine
(via ARM emulation) on many x86 Android devices.
We support developing Flutter apps with Android and iOS devices, as
well as with Android emulators and the iOS simulator.
We test on a variety of low-end to high-end phones but we don’t yet
have an official device compatibility guarantee.
We believe Flutter works well on tablets. We do not currently
implement all of the tablet-specific adaptations recommended by
Material Design, though we are planning further investment in this
area
The answer to this question also, partly, needs to take into consideration what parts of Android you want to take advantage of in your application. The question of what min version Flutter supports has been answered here a couple of times so I won't answer that, but the Android support libraries will also need specific min versions.
If you plan to use plugins of any kind then you will probably hit multiple issues if your min version is too low. Do you need Firebase? Do you need specific camera functions?
Google also just announced required bumps for min versions with regards to Google Play that you should review.
My advice is to follow documentation, analytics and best practices to determine what you "true" min version should be.
The Flutter documentation has this answer to Android and iOS. Now it says that support: Android Jelly Bean, v16, 4.1.x or newer, and iOS 8 or newer. However, this information can change according to the new Flutter version. By this reason, it is better that you review the next link:
https://flutter.dev/docs/resources/faq#what-devices-and-os-versions-does-flutter-run-on
Furthermore, it would be best if you analyzed the plugins because they could need higher versions of Android and iOS.
This answer can be useful :
Devices and OS versions on which Flutter runs
Mobile operating systems: Android Jelly Bean, v16, 4.1.x or newer, and iOS 8 or newer.
Mobile hardware: iOS devices (iPhone 4S or newer) and ARM Android devices.

I am working on one Flutter project. In which, We want to generate builds of Android, iOS, and HarmonyOS (Huawei). But I am not sure does Flutter supports this OS or not. I went through some of the stuff on the internet but was unable to figure out how to generate and what kind of commands were needed. Here, Anyone has previously generated HarmonyOS compatible build from the Flutter project. Please share your thoughts.
For now it is not possible directly from Flutter. Because of the change in architecture brought by Huawei with HarmonyOS it is not anymore an "Android device" and it doesn't run "Android applications".
Now what you can call "native HarmonyOS applications" are *.app files (not *.apk or *.aab)
Most recent answer on Quora to:
Will Harmony OS run Android apps?
Gives the following response:
Answered Jun 4, 2021 by Mahdi Parastech, Software Engineer
Nope, because:
The structure of the APIs are different.
Hongmeng (HarmonyOS) apps are in *.app, Android apps are *.apk
The structure of pages (activities) are different, Hongmeng uses some additional json files and puts pages inside *.har files.
Hongmeng uses Javascript too, and that's the only option in Wearable Hongmeng devices, but Android apps are just written in Java.

Apparently you should be able to migrate your native android application to HarmonyOS by using their IDE but the thing is that Flutter was not build for this architecture.
Except if the Flutter team decides for some reason to support HarmonyOS I don't think it will be possible to develop HarmonyOS applications by using Flutter.
This may be an incredibly stupid question, but I have not gotten a clear answer through google. Will the eclipse Blackberry plugin work for the new Blackberry as well as older versions? I am actually an android developer so this is quite a change for me. Any hint will be appreciated. Thanx
EDIT You can use the BlackBerry Runtime for Android apps to run Android Jelly Bean 4.2.2 (10.2) platform applications on the BlackBerry 10 OS. If you are developing for a previous version of BlackBerry 10 OS, use Android Gingerbread 2.3.3. To use the runtime, you must first repackage your Android applications to BAR file format, which is the compatible file format required for an application to run on the BlackBerry 10 OS.
Got this from here. Does this mean that I should write two apps? One for the old blackberry devices and one for the new one?
I'm not sure that the above is clear, so thought I would restate the position as I understand it:
Android applications, repackaged to run on BlackBerry devices, can be used on BB10 and PlayBook devices only. These can not be run on BBOS devices, i.e. BB 5/6/7.
The later releases of BB10, specifically 10.2+, supports Android applications developed using Jelly Bean 4.2.2.
PlayBook and previous levels of BB10, support Gingerbread 2.3.3.
So for example, my Z10, which is running BB10.1, would only be able to load repackaged Android applications developed using Gingerbread. My Curve, running OS 7.0, can't run any Android applications.
I need to emulate Android device (Samsung Tab 2) with version 4.0.3, but after choosing it in Android Virtual Device Manager and running it I get info in settings that it is a 4.0.4 version.
I need to run my web app written in html5 to reproduce some bugs.
Any idea about it?
The problem is that the emulator Android versions only correspond with specific versions from each API level. 4.0.3 and 4.0.4 are both in API level 15, so the emulator is only made available for Android 4.0.4. There is no Android 4.0.3 emulator; you'd have to find the system image for that or build it yourself.
As the most of you will know Android Emulators for >3.x don't support Renderscript. Now I found an Android Player called Bluestacks (tge most of you will know it I think). So I wanted to ask, if it's just me or does Bluestacks also not support Renderscript.

Ahmad
Google has published a compatibility library for Renderscript, which allows you to use it starting from Android 2.2 (API8).
This means that Renderscript could run even on bluestacks if it is still android 2.3.
The disadvantage is that it uses the CPU unless the OS version is 4.3 and above.
more information about it is available on the android developers blog, here
It is supposed to support RenderScript. As RenderScript is a part of android framework, all renderscript openGLES operations should be forwarded to host stack eventually.
According to the Bluestacks help forum Bluestacks is equivalent to Android 2.3.4 which doesn't support Renderscript as far as I know.
Actually the emulator images for Ice Cream Sandwich (4.0.x) and JellyBean (4.1.x) which come with the Android SDK does support Renderscript. The Honeycomb (3.0, 3.1, 3.2) emulator images do not.
I have installed android tools and eclipse successfully (making the hello World and hello widget examples) and have run these successfully on the Xperia X10 add-on that I downloaded from the developer site of SE.
However, my phone is running the updated Android 2.1, and any apps that I make will either have to run on 1.6, or will not be able to be tested on the Xperia X10 during development without moving it to my physical phone.
I have contacted Sony and they told me there is no add-on with 2.1 on it. And that is all they would say.
My Question:
Is there anyone out there who has developed for this phone, who knows what to do? Do I somehow run the SE update tool on the virtual phone to upgrade the OS of the image? Or am I missing something much more obvious?
As of April 2011, this is (an estimate of) Android usage share:
That's 3.5% for Android 1.6 and 2.7% for Android 1.5. As time goes by, those percentages will only decrease.
Just develop for 2.1.
Why do you prefer to use the emulator, anyway? Most Android devs (myself included) have found that the emulator is painfully slow, and it's just plain easier to plug in a real phone and test on that.
You can use the adb for getting your phone in debug mode.
Or you can just install your APKs via OTA or via USB in your physical phone.
Or you could just develop on 2.1 knowing that almost everything will work. I don't get the problem, really.
