this is the exact error i am facing

Caused by: org.gradle.workers.internal.DefaultWorkerExecutor$WorkExecutionException: A failure occurred while executing com.android.build.gradle.internal.res.ParseLibraryResourcesTask$ParseResourcesRunnable

with this i got 7 more errors which are

Caused by: com.android.ide.common.symbols.ResourceDirectoryParseException: Failed to parse XML file 'C:\Users\akki kisu\AndroidStudioProjects\MyApplication2\app\build\intermediates\packaged_res\debug\drawable\buttonbgcolor.xml'`

Element type "color" must be followed by either attribute specifications, ">" or "/>".

Caused by: org.gradle.workers.internal.DefaultWorkerExecutor$WorkExecutionException: A failure occurred while executing com.android.build.gradle.internal.res.ResourceCompilerRunnable

Caused by: com.android.aaptcompiler.ResourceCompilationException: Resource compilation failed (Failed to compile resource file: C:\Users\akki kisu\AndroidStudioProjects\MyApplication2\app\src\main\res\drawable\buttonbgcolor.xml: .

Have you tried search the the error first, https://stackoverflow.com/questions/57606462/a-failure-occurred-while-executing-com-android-build-gradle-internal-tasks — Takshak Rajput, May 19 '22 at 11:13
Thix XML code works on an empty App, so the problem is not thix file. However the resulting Activity is not a calculator but all "button" are overlapping each other because you're not using appropriate ConstraintLayout's attributes. — emandt, May 19 '22 at 14:03
According to the error buttonbgcolor.xml in your resource is not parsing. Please check if all tags are properly closed and the syntax is proper. — Priyank Jain, May 19 '22 at 17:07
