Android Studio's “expected resource of type” checks?

Question

Android Studio Beta (0.8) has a nifty new feature where it checks that some int parameters are not arbitrary integers, but rather have some properties.

Answer 1

All annotations, that you can use with android.support.annotation you can find here.

And technical doc about supporting annotations.

Answer 2

Try this answer: Its working... Put this code into your build.gradle

android {
 lintOptions {
    disable "ResourceType"
  }
}

Answer 3

(Thanks to @CommonsWare for the heads up).

There are Java annotations to support these checks in your own code. They can all be found in the android.support.annotations package:

• IdRes
• DrawableRes
• LayoutRes
• StringRes
• &c

In this case, for example, I could use:

private void mySetContentView(@LayoutRes int resourceId) {
    setContentView(resourceId);
}

and Android Studio will check that the provided resource id is indeed for a layout.

Moreover, these annotations are exported, so they can be especially useful when designing a library.
