Could not resolve all dependencies for configuration ':app:_debugCompile'.
Could not find any matches for com.android.support:appcompat-v7:19.+ as no

Android studio: How to delete crashlytics plugin

I'm using Android Studio 1.0.2.
Due to some reason i have to uninstall the Crashlytics plugin/SDK from my Android studio.
I have tried going to File>Settings>Plugins to remove Crashlytics, but this has not helped me, as i cannot find it in the plugin list.
Request if someone can provide a solution for this issue.

You need to delete crashlytics in app/build.gradle.
buildscript {
repositories {
maven { url 'http://download.crashlytics.com/maven' }
}
dependencies {
classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
}
}
compile 'com.crashlytics.android:crashlytics:1.+'
Delete line that show crashlytics in repositories and dependencies.
Delete file app/crashlytics.properties and app/main/assets/crashlytics-build.properties
Then build gradle again.

For plugins installed inside the Studio just go to File-Settings-Plugins and uninstall

You can go to the Preferences->Plugins on the search bar, you can search the plugin you want to remove or you can go >installed plugin tab and it will show you the list of installed plugin then select the plugin to remove just right click on it and it will show you the option>uninstall and then press on the Uninstall button.
File > Setting > plugins > installed plugins > right click on plugin > uninstall

In case you cannot delete a Plugin from Preferences->Plugins because is not on the list, navigate to
{User-Home}\AppData\Local\JetBrains\Toolbox\apps\AndroidStudio\ch-0\202.6787931.plugins
and simply delete its folder and restart Android Studio.
You may have to look up that path yourself, as mine is for a JetBrains Toolbox installation of Android Studio, but the process should be the same.
Hint: In my case the plugin in question lived in a folder named "plugin", what I had to figure out first.

For Mac User find plugin on below path.
/Users/username/Library/Application
Support/Google/AndroidStudio2021.3/Plugins
Bold text would be different depending on computer environment + Android Studio version

For the new Android Studio version (Android Studio Electric Eel | 2022.1.1).
To delete or uninstall the Plugin, the steps are below:
Settings -> Plugins -> Choose Tab Installed -> Select the Plugin you want -> Click Icon Setting (Right of Title) -> Uninstall

Can't open Android samples using Android Studio

I just started using Android Studios and wanted to look at some of the sample code that Google already provides in their apk samples.
However, when I try importing a project, it tells me:
"You are using an old, unsupported version of Gradle. Please use version 1.8 or greater.
Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.)
Consult IDE log for more details (Help | Show Log)"
In my .gradle/wrapper/dists, I have gradle-1.6-bin and gradle-1.8-bin.
I tried updating the gradle to 1.8 from 1.6 in the gradle-wrapper.properties file in the project itself, but I can't seem to save the file after editing it.

Step 1: Change line in build.gradle:
dependencies {
classpath 'com.android.tools.build:gradle:0.6.+'
}
Step 2:
In the YourProject.iml file, delete the entire component name="FacetManager" tag.
Step 3
(Maybe not necessary): In the Android SDK manager, install (if not already installed) Android Support Repository under Extras.

Errors after creating a new project in Android Studio

Just now I updated my android studio from build 130.737825 to build 130.878379. When I create a project for the first time, I am getting following error.
Gradle: A problem occurred configuring project ':MyApplicationadfaldf'.
> Failed to notify project evaluation listener.
> Could not resolve all dependencies for configuration ':MyApplicationadfaldf:_DebugCompile'.
> Could not find any version that matches com.android.support:appcompat-v7:+.
Required by:
MyApplicationadfaldfProject:MyApplicationadfaldf:unspecified
What is the reason?

For others, who may be facing the same problem,
Go to Tools-> Android-> SDK Manager, and update all repositories. Now, everything will work properly.

Same issue in my project was fixed with this:
In Android Studio:
-> Go to File menu -> Settings -> Gradle ->
Now in Gradle Settings just check Use Auto-Import Now update Maven will be updated in Android Studio and this error should be gone.
