AndroidSDK | Android SDK for integrating with TradeIt for trading | Business library

I'm trying to use nix flakes for android development.

This is my flake.nix:

I just want to set android emulator without studio-ide and use it like a mobile and tweak it.

I have downloaded command-line tools from https://dl.google.com/android/repository/commandlinetools-linux-6858069_latest.zip

Unzipped in folder $HOME/AndroidSDK.

I just want to run some emulators.

Then ran below

Again, after updating to VS 8.9.1 on Mac I'm getting this error while trying to compile my Android project:

I'm trying to run my Flutter app on my phone, connected via USB, in order to debug.

It stopped working from one day (May 13, if it matters) to the next. Quite frustrating is that I made no changes since it last worked. Since the last time I clicked the Android Studio "play" button on May 13, there were only code changes, which all ran fine via hot reload. Then the next day when pressing the play button, it suddenly complains about JAVA_HOME not being set.

After some troubleshooting, I now get the error message

I have a project which running well yesterday, but today, I got this error

As mentioned in image my app is violating there policy but i've another app for the same which is for doctor's and that app is using the same libraries and almost everything similar to this app but still my doctor app is accepted without any violation

androidx.fragment.app.FragmentActivity.startActivityForResult and they are saying your startActivityForResult is responsible for this but i'm only calling this line for opening camera and gallery.

i've tried uploading my app multiple time's with upgraded gradle and there remediations available here https://support.google.com/faqs/answer/9267555 but still no success.

you can also refer below image for further details.

my gradle

I have a big problem with Visual Studio Community 2019 V16.9.0. I have installed this update and when I tried to run again my Xamarin.Android project it's led to crash. I have tried to make a new project, the name was auto-generated "App3" because I don't want to modify anything in order to see that the project can be built successfully. The build failed as you can see in the picture below.

VS also can't see the References for the project.

I have tried to repair the SDK but it doesn't help because the reparation has failed.

I let you als the errors that had been generated.

I'm using a native ios sdk. I have created an envelope and signed it. For creating and signing the envelope I was using the documentation and suggestions that were given on this topic.

Now, I want to download my signed document. In Android mobile sdk there is a DSEnvelopeDelegate which has a method downloadCompletedEnvelopeDocument (description here).

But in iOS SDK I can't find any methods which make the same work. How to download the completed envelope document using iOS SDK? In case if it not available in iOS SDK how to do this (maybe use some API etc)?

I need to get the AAB and APK file that the bundleRelease and assembleRelease generate in the android > app build folder. However for some reason I'm not able to get it because whenever I run one of those commands they would hang in the app:multiDexListRelease step.

I'm running React Native 0.63.2 version

Here's the log that I'm getting so far: Ran these commands multiple times and as you can see at the end of the log, they would take a crazy amount of time without timing out.
