Why won't Android Support Libraries work in my project?

android, android-gradle-plugin, android-support-library, compiler-errors

Solution

I think you're placing these lines in the wrong file.

They should go in the module's `build.gradle` file, not in the project's one (which this would seem to be, from the screenshot).

Also, the `dependencies` tag should not be a child of anything else. something like:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    ...
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.android.support:support-v4:18.0.+"
    ...
}

EDIT Did you see the comment? :)

// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files

Problem

Using Android Studio, I followed the steps at https://developer.android.com/tools/support-library/setup.html as acurately as I could, but it told me the following error: Error:Could not find method compile() for arguments [com.android.support:appcompat-v7:18.0.+] on org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler_Decorated@18899229. Please install the Android Support Repository from the Android SDK Manager. Open Android SDK Manager But I have already installed the Support Repository and Library! Since I also got an error saying `compile` doesn't belong in the `dependencies` block, so I changed it to `classpath`, and got the following, similar error: Error:Could not find any version that matches com.android.support:appcompat-v7:18.0.+. Required by: :ExpenseTracker:unspecified Please install the Android Support Repository from the Android SDK Manager. Open Android SDK Manager As you can see here, it still thinks the ASR isn't installed, but as the screenshot proves, it is. So what am I doing wrong here?
