Error occurs after I have uploaded icons for app (in Android Studio with Flutter)

I have created app icons with a website called appicon. It provided icon files for both android(mipmap files) and ios devices(an Assets.xcassets file), which I added to their respective locations being (C:\Users\user\StudioProjects\i_am_rich(name of app)\android\app\src\main\res) for android and (C:\Users\user\StudioProjects\i_am_rich\ios\Runner) for ios.
When I run the program the following error is displayed:
FAILURE: Build failed with an exception.
* What went wrong:

I am learning Android Studio as the IDE with flutter, as a beginner, so I don't understand the problem nor what I have to do to fix it.
Help and, possibly, an explanation would be greatly appreciated :)

The website you mentioned does generate correct names and correct order of directories it seems. so most probably this is an issue with where you have put your files or the name of the files.
The 5 directories of icons must be copied to android\app\src\main\res folder.
and make sure in each directory you have a file called ic_launcher
if all is correct, please run flutter clean command and try again.
also by anychance the webisite generating incorrect files, try using this web site AndroidAssetStudio

Can anyone help me to solve this problem...? please...

This is what happens when aapt fails to create an archive.
First make sure you are using the latest IDE and SDK. aapt for packaging is obsolete, and the earlier aapt2 has many bugs.
If they are up to date, try to check if the following processes on your computer have read/write access to the project directory.
[your android sdk path]\build-tools[your sdk version]\aapt.exe
[your android sdk path]\build-tools[your sdk version]\aapt2.exe
[your android studio path]\bin\studio64.exe
[your android studio path]\bin\fsnotifier64.exe
[your android studio path]\jre\bin\java.exe
[your android studio path]\jre\bin\javaw.exe
If you haven't set permissions manually, they are usually blocked by security software.
I recently ran into this problem and spent a lot of time finally found out that the security software on my workstation was not adding aapt2 and aapt to the allowed list for the project repository.

Jenkins mergeDebugResources FAILED - no access to files

I would like to run espresso tests on jenkins. I did configuration like here

Any sugestions what can be wrong?

This is happening because AAPT2 still has issues with long paths on windows (only supports paths up to 145 characters or so for now, sadly). This file path is around 170, so it's over that limit.
The issue should be fixed soon, in the meantime you can move your cache directory closer to the C: root.

I faced the same issue. The solution proposed here helped.
Simply add enviornmental variable GRADLE_USER_HOME
env GRADLE_USER_HOME= ${WORKSPACE}/gh
Note: Make sure gh is close to the main drive location

Failed to find target with hash string 'android-25' in: /home/hisham/Android/Sdk

Been trying to debug this issue for hours! Tried many solutions online, none seems to be working.

How do I fix this?

Finally got it fixed! Not sure which one of the following fixed it though.
Change $ANDROID_HOME inside ~/.bashrc from ANDROID_HOME=$HOME/Android/Sdk to ANDROID_HOME=$HOME/Android/Sdk/platform-tools
Deleted version 25's folder inside platform-tools folder in the Sdk and installed version 25 again.
After doing the two above, restarted the system and I am now able to compile and build ionic app to .apk files.
PS : This might be just only in my personal computer, and you might be facing the same issue due to different issue. Hope this helps.

[ERROR] An error occurred while running cordova run android (exit code 1).
Solved
Solved: Re-create the project and add the features again!

just put this code inside build.gradle on the last part
configurations.all {
resolutionStrategy {
force 'com.android.support:support-v4:27.1.0'
}
}

If you update the v4 v7 version to 26.0.0,
you also should change the CompileSdkVersion and BuildToolsVersion
to 26.0.0

Strange cause of this error for me was that I was missing a drawable from a layout. I copied the layout from another project and forgot to copy the drawable before running my project.
Also, check that the activity names in your layouts do not have spaces.

this problem comes from the mismatch project environment and executing platform environment.
try to create a new project and run in the same platform environment.
if its run, copy-paste old project src files.
$ ionic start
$ cd "project_name"
$ ionic cordova platform add android
$ ionic cordova run android
copy-paste old project src files
