Known direct subclasses [MockResources](https://developer.android.com/reference/android/test/mock/MockResources) [MockResources](https://developer.android.com/reference/android/test/mock/MockResources) *This class was deprecated in API level 24. Use a mocking framework like [Mockito](https://github.com/mockito/mockito). New tests should be written using the [Android Testing Support Library](https://developer.android.com/tools/testing-support-library).*
*** ** * ** ***
Class for accessing an application's resources. This sits on top of the asset manager of the application (accessible through `https://developer.android.com/reference/android/content/res/Resources#getAssets()`) and provides a high-level API for getting typed data from the assets.
The Android resource system keeps track of all non-code assets associated with an application. You can use this class to access your application's resources. You can generally acquire the `https://developer.android.com/reference/android/content/res/Resources` instance associated with your application with `https://developer.android.com/reference/android/content/Context#getResources()`.
The Android SDK tools compile your application's resources into the application binary at build time. To use a resource, you must install it correctly in the source tree (inside your project's `res/` directory) and build your application. As part of the build process, the SDK tools generate symbols for each resource, which you can use in your application code to access the resources.
Using application resources makes it easy to update various characteristics of your application without modifying code, and---by providing sets of alternative resources---enables you to optimize your application for a variety of device configurations (such as for different languages and screen sizes). This is an important aspect of developing Android applications that are compatible on different types of devices.
After `https://developer.android.com/reference/android/os/Build.VERSION_CODES#R`, `https://developer.android.com/reference/android/content/res/Resources` must be obtained by `https://developer.android.com/reference/android/app/Activity` or `https://developer.android.com/reference/android/content/Context` created with `https://developer.android.com/reference/android/content/Context#createWindowContext(int,%20android.os.Bundle)`. `https://developer.android.com/reference/android/content/ContextWrapper#getResources()` may report wrong values in multi-window or on secondary displays.
For more information about using resources, see the documentation about [Application Resources](https://developer.android.com/guide/topics/resources).

```
public DisplayMetrics getDisplayMetrics ()
```
Returns the current display metrics that are in effect for this resource object. The returned object should be treated as read-only.
Note that the reported value may be different than the window this application is interested in.

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/graphics/drawable/Drawable` | Drawable An object that can be used to draw this resource.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/android/content/res/Resources.NotFoundException` | Throws NotFoundException if the given ID does not exist. |
### getDrawable
Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
Deprecated in [API level 22](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public Drawable getDrawable (int id)
```
**This method was deprecated in API level 22.**
Use `https://developer.android.com/reference/android/content/res/Resources#getDrawable(int,%20android.content.res.Resources.Theme)` instead.
Return a drawable object associated with a particular resource ID. Various types of objects will be returned depending on the underlying resource -- for example, a solid color, PNG image, scalable image, etc. The Drawable API hides these implementation details.
**Note:** Prior to `https://developer.android.com/reference/android/os/Build.VERSION_CODES#JELLY_BEAN`, this function would not correctly retrieve the final configuration density when the resource ID passed here is an alias to another Drawable resource. This means that if the density configuration of the alias resource is different than the actual resource, the density of the returned Drawable would be incorrect, resulting in bad scaling. To work around this, you can instead manually resolve the aliased reference by using `https://developer.android.com/reference/android/content/res/Resources#getValue(int,%20android.util.TypedValue,%20boolean)` and passing `true` for `resolveRefs`. The resulting `https://developer.android.com/reference/android/util/TypedValue#resourceId` value may be passed to this method.
**Note:** To obtain a themed drawable, use `https://developer.android.com/reference/android/content/Context#getDrawable(int)` or `https://developer.android.com/reference/android/content/res/Resources#getDrawable(int,%20android.content.res.Resources.Theme)` passing the desired theme.
| Parameters ||
|---|---|
| `id` | `int`: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/graphics/drawable/Drawable` | Drawable An object that can be used to draw this resource.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/android/content/res/Resources.NotFoundException` | Throws NotFoundException if the given ID does not exist. |

public Drawable getDrawableForDensity (int id,
int density)
```
**This method was deprecated in API level 22.**
Use `https://developer.android.com/reference/android/content/res/Resources#getDrawableForDensity(int,%20int,%20android.content.res.Resources.Theme)` instead.
Return a drawable object associated with a particular resource ID for the given screen density in DPI. This will set the drawable's density to be the device's density multiplied by the ratio of actual drawable density to requested density. This allows the drawable to be scaled up to the correct size if needed. Various types of objects will be returned depending on the underlying resource -- for example, a solid color, PNG image, scalable image, etc. The Drawable API hides these implementation details.
**Note:** To obtain a themed drawable, use `https://developer.android.com/reference/android/content/Context#getDrawable(int)` or `https://developer.android.com/reference/android/content/res/Resources#getDrawableForDensity(int,%20int,%20android.content.res.Resources.Theme)` passing the desired theme.
| Parameters ||
|---|---|
| `id` | `int`: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
|
| `density` | `int`: the desired screen density indicated by the resource as found in `https://developer.android.com/reference/android/util/DisplayMetrics`. A value of 0 means to use the density returned from `https://developer.android.com/reference/android/content/res/Resources#getConfiguration()`. This is equivalent to calling `https://developer.android.com/reference/android/content/res/Resources#getDrawable(int)`.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/graphics/drawable/Drawable` | Drawable An object that can be used to draw this resource. This value may be `null`.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/android/content/res/Resources.NotFoundException` | Throws NotFoundException if the given ID does not exist. |
