When i have downloaded android 10.0.0_r1 aosp code from the android source it took almost 150gb for the first time. Actually many said its about 50gb. Later i tried downloaded the android 4.0.0_r1 i have got just 20gb. but some folders got installed with bionic.git like that.There is no envsetup.sh file inside build.git folder and another issue was all files got downloaded in the platform folder not into my aosp folder which i set for download.can any one provide clear steps to download the source?

Whenever I have a problem with Flutter I often find answers saying 'reinstall the Flutter SDK'.
However I cannot find any clear instructions on how to do this (please direct me to them if I am wrong).
General Questions
By 'clear' instructions, I mean ones that answer the following questions:
What folder(s) should be deleted to remove Flutter from my computer?
Do any files need to be copied and added to the new Flutter folder once I reinstall it?
Do I need to make any changes to my Flutter projects either before or after reinstalling Flutter?
Will I need to download the same channel (stable, beta, dev, master) as what I am currently on?
Will I need to make any changes to my PATH?
Are these the correct steps to reinstall?
Go to https://flutter.dev/docs/development/tools/sdk/releases?tab=macos
Download the zip of the release you want (safest to use latest stable version)
Open Flutter zip in SAME location as the previous Flutter folder was
Done - I should now be able to run Flutter projects without any further steps
Apologies if these seem like very basic questions but for someone fairly new it isn't obvious what the answers are.
I'm new to Flutter and had similar issues. I will outline what worked for me but meanwhile, to answer your questions:
What folder(s) should be deleted to remove Flutter from my computer?
The Flutter folder which you unzipped and, presumably added to $PATH. Although not deleting it isn't going to pose an issue. I have separate folders of different versions of Flutter on my computer and it's fine.
Do any files need to be copied and added to the new Flutter folder
once I reinstall it?
Try a fresh download of Flutter and unzip it? There is no need to copy or add any files to the Flutter folder once you've (re)installed it.
Do I need to make any changes to my Flutter projects either before or
after reinstalling Flutter?
Not exactly sure what you mean by make changes to your Flutter projects. If you ran flutter doctor and didn't get any errors, then it's good to go. When you create a new Flutter project either in Android Studio, VS Code or Terminal, it will automatically handle whatever file copying business.
Will I need to download the same channel (stable, beta, dev, master)
as what I am currently on?
No, you only need one. I suggest you download one from Stable unless you need web support, which would be Beta.
Will I need to make any changes to my PATH?
After you've unzipped your fresh copy of Flutter (note the folder destination), open Terminal and change the path to said folder destination but make sure it's the /bin folder you're mapping to.
Are these the correct steps to reinstall?

Yes and no. You're missing a number of steps. Please follow the full Flutter installation guide depending on your OS.
It took me about 10 hours over two days and a VPN to finally get it working in China with an old install from two years ago when I was in Montréal.
I cloned the project and followed the insctructions in the readme that basically say to extract a zip and move to the right place. The built and got this error:
/Users/**/vidyo/vidyo.io-connector-react-native/ios/VidyoConnectorView.h:14:9: 'Lmi/VidyoClient/VidyoConnector_Objc.h' file not found
Is this a known issue when using the Vidyo react native SDK?
This error means that it cannot find the public headers which are located inside. You need to download the VidyoClientIOS/Android SDK and place it in the specified path.
Download the latest Vidyo.io Android & iOS SDK packages:
Unzip VidyoClient-AndroidSDK folder and move contents of VidyoClient-AndroidSDK/lib/android to VidyoConnector-react-native/android/app/libs/android
Unzip VidyoClient-iOSSDK folder and move contents of VidyoClient-iOSSDK/lib/ios to VidyoConnector-react-native/ios/lib/ios
In javascript, we have NPM and the node_modules folder in every project. I was not able to find a similar concept for Dart/ Flutter, except the build folder in my app, which contains a folder of a few dependencies I have in pubspec.yaml. It doesn't have any of the source code though, and I think it's actually built from something else. I've also looked in /usr/local/flutter/packages which is where my flutter is installed, but it only shows flutter_driver, flutter_goldens, and more seemingly unrelated folders.
I guess if wanted to read the source code, I really need to find the repo and read from that, or is there a location for dependencies I haven't looked?
I even found projectDir/.dart_tool/pub, which didn't have any of my packages.
From the documentation:
Dependencies downloaded over the internet, such as those from Git and
the pub.dev site, are stored in a system-wide cache. This means that
if multiple packages use the same version of the same dependency, it
only needs to be downloaded and stored locally once.
By default, the system package cache is located in the .pub-cache
subdirectory of your home directory (on Mac and Linux), or in
%APPDATA%\Pub\Cache (on Windows; the location might vary depending on
the Windows version). You can configure the location of the cache by
setting the PUB_CACHE environment variable before running pub.
So for Mac and Linux for example, this would be ~/.pub-cache/hosted/pub.dartlang.org by default.
In Android Studio
I could directly view the source code of the package under `
[External Libraries/Dart Packages/Your Packages]
`
You can get pubspec downloaded from your flutter sdk location .
/flutter/.pub-cache/hosted/pub.dartlang.org/
You can also clone package git .
If you are running Windows as your OS, you can find the packages under the folder that you installed your Flutter SDK to when setting up Android Studio.
In my case - using Windows 10 - the path is as follows, where C:\ is my primary harddrive and flutter\ the folder containing the Flutter SDK...
C:\flutter\.pub-cache\hosted\pub.dartlang.org\english_words-4.0.0
The above path for instance points to the "english words package", containing the most ~5000 used English words and some utility functions, which are mentioned and used in the Flutter tutorial on their official page for writing and running your first Flutter app.
https://pub.dev/packages/english_words
If you have installed flutter using snap then the location might be
/home/user/snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org
I had forgotten that I've been command + clicking into these libraries all the time in VSCode.
However, it looks like packages are not stored in the app folder. Packages that we use in our projects are downloaded to $FLUTTER_PATH/.pub-cache, so if I'm looking for camera picker plugin, its in
/usr/local/flutter/.pub-cache/hosted/pub.dartlang.org/image_picker-0.6.5+2/lib/image_picker.dart
If you are using VScode you can find these dependencies under the dependencies window:
I want to make a complete backup of the Flutter project, and I noticed the build folder is the biggest one.
Size Details:
Total App Size: 889.6 MB
Build Directory: 743 MB
Remaining directories, including ios, android, assets and lib: 146 MB
I think, zipping project excluding build directory would be considered full backup and it will contain everything needed to start again.
Q. Is that correct? (if I'm wrong then is there any way to reduce app size?)
Delete build folder.
Delete Pod folder from IOS Directory
.gradle folder from android Directory
& if you have release & build folder in Android then delete it
Run Command: Fluter Clean
Now Folder will be 1MB to 10MB, depending on assets folder size.
To start with i would suggest git versioning with an online (public or private) repository as a good way to back up your code. To answer your Question, There's absolutely no problem with leaving out the build folder, Actually almost by default git will ignore the build folder. Note that every time you compile the app, that build folder is refreshed, actually its always good to start by cleaning it
In IntelliJ idea base ides (like Android Studio), you can get a lightweight .zip backup from your code.
Just follow this path in the top menu:
File> Export> Project to Zip File
I've been working on a mobile game in Unity for over a month, saving all my work to OneDrive. Today I restarted my computer and when it loaded back up I tried opening my project and it failed. I looked through my OneDrive and half my files are missing! I've been on the phone with Microsoft support all day and I can't get those files back.
I have the apk file for the game loaded onto my phone. Is there anyway to reverse build this thing back onto Unity or just get the files back from the apk file ?
If by APK you mean Android's APK file you can just 'unzip' it and get at least you xml files and other resources such as images. All classes will be packed to classes.dex file, which can be converted to Java's JAR by dex2jar tool. However JAR will give you only Java's binaries. You could further de-compile them to Java files, but they are not going to look pretty or very readable.
Well, at least you can recover you XML layouts.
Are the files in your recycle bin on the OneDrive website or locally? Often times when OneDrive files go missing they can be found there.
