Can't determine type for tag '<macro name="m3_comp_bottom_app_bar_container_color">?attr/colorSurface</macro>'

I'm having a problem with running my android app:
Can't determine type for tag '<macro name="m3_comp_bottom_app_bar_container_color">?attr/colorSurface</macro>'

That is caused by 1.7.0:
implementation 'com.google.android.material:material:1.7.0'
You better stick to 1.6.0 till they fix this
implementation 'com.google.android.material:material:1.6.0'

In your build.gradle file where "dependencies" section is paste this:
implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.6.0'
in this section. And remove old strings with same text and other number versions. (in my case:
implementation 'androidx.appcompat:appcompat:1.5.1'
implementation 'com.google.android.material:material:1.7.0'
). Have worked for me.

Upgraded android gradle plugin to 7.2.2 and the problem is solved. Try updating Android Studio too

Rationale
To expand on the existing answers, the release notes for Material Components for Android 1.7.0 mentions that they have updated the minimum requirements for your project (emphasis mine):
New minimum requirements for your app's project:
Update to Android Gradle Plugin (AGP) version 7.2.0
Update to Gradle version 7.3.3
Update to Java 8 (version 1.8)
Update to Android Studio Chipmunk, version 2021.2.1
This is also mentioned in their (updated) Getting Started guide (again, emphasis mine):
5. Gradle, AGP, and Android Studio
When using MDC-Android version 1.7.0-alpha02 and above, you will need to make sure your project is built with the following minimum requirements, in order to support the latest build features such as XML macro:
Gradle version 7.3.3
Android Gradle Plugin (AGP) version 7.2.0
Android Studio Chipmunk, version 2021.2.1
Updating the Android Gradle Plugin
You can update the Android Gradle plugin as follows:
Gradle plugins DSL
The plugin declaration can be found in the top-level build.gradle/build.gradle.kts file:
plugins {
// Or "com.android.library"
id("com.android.application") version "7.2.2" apply false
}
Buildscript classpath
Update the AGP classpath dependency (usually in the top-level build.gradle/build.gradle.kts file):
classpath("com.android.tools.build:gradle:7.2.2")

update your build.gradle file as below:
classpath 'com.android.tools.build:gradle:7.2.1'
It will fix the issues, remember v7.3.x wont fix the issue, so stick to 7.2.1 as of now.

For Flutter User with this issue this is how you solve it::
Goto : build.gradle
change "classpath 'com.andriod.tools.build:gradle:5.6.0'"
to
"classpath 'com.andriod.tools.build:gradle:<latest version>'"
in my case :: classpath 'com.android.tools.build:gradle:7.2.1'
then goto :: android/gradle/wrapper/gradle-wrapper.properties
then change
distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.3-all.zip
to
distributionUrl=https\://services.gradle.org/distributions/gradle-<latest>-all.zip
in my case distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-all.zip

In build.gradle(:app),
Updating, compileSdk and targetSdk to 33 helped me(from 32).

In order to get over with this. Upgrade to the latest gradle version as well as latest Android Studio.
I was also facing this issue and I followed these steps :
Upgraded Android Studio to Android Studio Dolphin | 2021.3.1 Patch 1
gradle version to 7.3.1 in project build.gradle
kotlin version to 1.7.20 in project build.gradle
targetSdkVersion and compileSdkVersion to 33
latest version of dependencies in app's build.gradle
And the project is perfectly working fine now.

I resolved it by replacing implementation 'androidx.recyclerview:recyclerview:1.2.1' instead of implementation 'com.google.android.material:material:1.7.0' in build.gradle(:app)

Upgraded android gradle plugin >= 7.1.0 and the problem is solved.
classpath "com.android.tools.build:gradle:7.1.0"

After wasting 2 hours and ruining my mood solution was simply upgrading your android studio version, most probably you are using an older version like Arctic fox or something like that, upgrade to dolphin or something higher. Hope it help, and yes in dolphin version it will give error of 30.0.3 but don't worry it gives you an attached link to install 30.0.0 SDK in console itself, so chill and keep developing.

first, in the gradle build file, change the implementation from 1.7.0 to 1.6.0
Next, open the colors file and change the color of the tag (#) which has 7 digits to a 6 digit tag. Because usually the default color of tags on Android Studio is sometimes 7 digits or 6 digits

I solved this by :
Adding in build.gradle:
implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.5.0'
adding android:exported="true" in Manifest

Android Studio - Create new project with errors?

I create a new android studio project over the wizard and choose Empty Activity (checked backward compatibility too). After the project is created, I got this two errors:
What is wrong? I don´t change any line code and I don´t find any solution for this.
I use the current version of android studio (checked updates a minute ago):
Android Studio 3.1.3
Build #AI-173.4819257, built on June 4, 2018

Thanks!

You may want to confirm these details
compileSdkVersion 27

Clean and Rebuild Project

Make sure you have the correct imports. Try:
import de.kampis_elektroecke.dogsvscats.R;

Try this.Goto: src -> main -> res -> style.xml and add Base. to the style tag parent attribute.
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
...
</style>
If that doesn't work, see this post:Theme.AppCompat.Light resource not found in Android Studio

Kotlin javaClass<> missing dependency in latest Android Studio 3.0

Toolchain:
Android Studio 3.0 Canary 2:
Build #AI-171.4041253, built on May 24, 2017
JRE: 1.8.0_112-release-b736 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Mac OS X 10.12.5
Google SDK/Tools: I have downloaded the latest "all" (Android O, tools, libraries, etc. at least according to Android Studio SDK Manager).
Problem: javaClass<> is missing and Android Studio can't "import it".
What I did:
Create new Android project, target API 23 and told it to include a "basic activity".
Added the Gradle dependencies for ViewModel and Room taken from: https://developer.android.com/topic/libraries/architecture/adding-components.html
These are the lines I added to my App Module's gradle file:
compile "android.arch.lifecycle:runtime:1.0.0-alpha1"
compile "android.arch.lifecycle:extensions:1.0.0-alpha1"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha1"
compile "android.arch.persistence.room:runtime:1.0.0-alpha1"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha1"
The Kotlin reference in the same Gradle is: compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" (I didn't add that one, came automatically)
I then created a simple Kotlin class called MainViewModel:
import android.arch.lifecycle.ViewModel
class MainViewModel : ViewModel() {}
Then I went to my Activity and tried to do what this Google Documentation says: https://developer.android.com/topic/libraries/architecture/viewmodel.html
It's in Java but converted to Kotlin, I think it should look like:
val mainViewModel = ViewModelProviders.of(this).get(javaClass<MainViewModel>)
The problem is that Android Studio is not finding javaClass and the fix (to press ⌥⏎) doesn’t do anything.
What am I missing?

I decided to try to use the Java To Kotlin conversion. So I created a new Activity in Java, and wrote the above code as the java documentation states.
After the class was working, I did Code -> Convert Java Class To Kotlin in Android Studio, and the resulting Kotlin class had the following line:
val viewModel = ViewModelProviders.of(this).get(MainViewModel::class.java)
This compiled perfectly. I will have to learn more about which one is correct, but this one may save you some time if you’re, like me, new to the language.

Failed to resolve: com.android.support:appcompat-v7:15.+

i find 2 solutions for this problem, but both didn't work. So i decided to ask you.
I'm using Debian 8 Jessie and Android Studio 1.4
I just created new project and when i tried to start it i got an error:
" Failed to resolve: com.android.support:appcompat-v7:15.+ "
And gives me 3 option.
1) Install Repository and sync project
When i tried it i got an error like this:
Loading SDK information...
Ignoring unknown package filter 'extra-android-m2repository'Warning: The package filter removed all packages. There is nothing to install.
Please consider trying to update again without a package filter.
And down of the window:
Install failed. Please check your network connection and try again. You may continue with creating your project, but it will not complete correctly without the missing components.
2) Show in File
It's my build.gradle dependencies:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:15.+'
}
Error in this line:
compile 'com.android.support:appcompat-v7:15.+'
3) Show in Project Structure dialog
Dependencies windows is opened and about this line again:
compile 'com.android.support:appcompat-v7:15.+'
Tried Solutions:
Firstly, i tried to download version sdk again. I deleted Android 4.0.3 and re-download again but still same error.
After that i tried to download support library which recommended in; topic 1 , topic 2. After i download Android Support Library, rev 23.0.1 still got same error.
After that i tried to solve my problem with fixing first option in error (install repository and sync project. And i found some topics again. I checked my HTTP Proxy section in Setting, already "No proxy" is selected.
So, i tried everything i found, but still i got this error. Someone can help me please?

After you downloaded the latest support library with your sdk manager, you can set that version in your gradle file.
If you downloaded 23.0.1 set it like this:
compile 'com.android.support:appcompat-v7:23.0.1'
EDIT:
Also note following hint, given by Android Studio, when using + in Version number:
Avoid using + in version numbers; can lead to unpredictable and unrepeatable builds (com.android.support:appcompat-v7:23.1.+)
Using + in dependencies lets you automatically pick up the latest
available version rather than a specific, named version. However, this
is not recommended; your builds are not repeatable; you may have
tested with a slightly different version than what the build server
used. (Using a dynamic version as the major version number is more
problematic than using it in the minor version position.)

Edit build.gradle
Replace 'com.android.support:appcompat-v7:15.+' with 'com.android.support:appcompat-v7:18.0.0'
Sync It
May be this will help you. If in case this will not work i.e. show error then see for installation of app-compat in "%homepath%\AppData\Local\Android\sdk\extras\android\m2repository\com\android\support\appcompat-v7"
Search for the oldest version and put the version number at xx: 'com.android.support:appcompat-v7:xx'

I installed Java and Android Studio today.
When creating my first project with API level 15 as minSDK, I faced the same problem.
As far as I can tell, it seems the installation of the sdk works not pretty well. For me, API level 15 had only the SDK platform. API level 23 had platform and sources. I don't remember, which tools where installed.
To solve the problem, I started the sdk manager (old version), removed api level 15 completely and installed api level 23 as suggested. After that, a newly created project (again with minSDK 15) was properly created.
The difference in the app/build.gradle file is obvious.
Maybe this helps other people facing the same issues, or one of the gurus can further explain, what happened.
Kind Regards

Got same errors.

Above changes + Build >> Clean Project.
Hope that helps!

Go to Built tab select "Edit Built types" select properties tab and check built tool version it was 19.1.1 for me.
Then go to built.gradle change compile to 'com.android.support:appcompat-v7:19+' . I changed to 19+ because my built version is 19.1.1 ; You have to select according to your built version(18+,19+,20+ like that).

Try following solution:
In Android studio:
Go to File -> Project structure
Check the selected Build Tools Version.
update your build.gradle for app with selected build tools version.
for e.g. 19.1.0
After update, Run Clean.
Please refer below screenshot.[Project Structure-> Build Tools Types][1]

I had a similar error message when creating a project.
fail to resolve com.android.support:appcompat-v7:14.+
I notice that if I create a new project with support for 4.0.3 instead of 4.0, no error occurs. I am using android studio 1.5. Hope this helps.

in my case, support and wearable versions were different, after making them exactly same, gradle build completed successfully.
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.support:wearable:1.0.0'
compile 'com.google.android.gms:play-services-wearable:11.0.4'
provided 'com.google.android.wearable:wearable:1.0.0'
}

The latest support library v4 requires minSdk(API 20, L Preview)?

I'm trying to run a project with the Android Studio 0.8.0 beta and the latest tools, it requires API 20, so it fails to run on the device with API 19
Any ideas?

If you configured your gradle settings to compile the latest version of
'com.android.support:support-v4:+'
'com.android.support:appcompat-v7:+'
then the RC will be downloaded, which requires the L - Preview.
See the Answers here.
Use
'com.android.support:support-v4:20.+'
'com.android.support:appcompat-v7:20.+'
everywhere in your project instead.

The problem still arises with transitive dependencies. Gradle offers a way to force the usage of a specific version of a dependency.
For example you can add something like:
configurations.all {
resolutionStrategy {
force 'com.android.support:support-v4:20.+'
force 'com.android.support:appcompat-v7:20.+'
}
}
to your build.gradle.
If you want to learn more about gradle resolution strategies refer to this guide http://www.gradle.org/docs/current/dsl/org.gradle.api.artifacts.ResolutionStrategy.html
I found this while reading the corresponding issue which I will link here
