## ProGuard
If you use [Glide](https://github.com/bumptech/glide) as your image engine, add rules as Glide's README says.
And add extra rule:
```pro
-dontwarn com.squareup.picasso.**
```

If you use [Picasso](https://github.com/square/picasso) as your image engine, add rules as Picasso's README says.
And add extra rule:
```pro
-dontwarn com.bumptech.glide.**
```
**Attention**: The above progurad rules are correct.

## How do I use Matisse?
#### Permission
The library requires two permissions:
- `android.permission.READ_EXTERNAL_STORAGE`
- `android.permission.WRITE_EXTERNAL_STORAGE`

So if you are targeting Android 6.0+, you need to handle runtime permission request before next step.

#### Simple usage snippet
------
Start `MatisseActivity` from current `Activity` or `Fragment`:

```java
Matisse.from(MainActivity.this)
.choose(MimeType.allOf())
.countable(true)
.maxSelectable(9)
.addFilter(new GifSizeFilter(320, 320, 5 * Filter.K * Filter.K))
.gridExpectedSize(getResources().getDimensionPixelSize(R.dimen.grid_expected_size))
.restrictOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED)
.thumbnailScale(0.85f)
.imageEngine(new GlideEngine())
.showPreview(false) // Default is `true`
.forResult(REQUEST_CODE_CHOOSE);
```

#### Themes
There are two built-in themes you can use to start `MatisseActivity`:
- `R.style.Matisse_Zhihu` (light mode)
- `R.style.Matisse_Dracula` (dark mode)

And Also you can define your own theme as you wish.

#### Receive Result
In `onActivityResult()` callback of the starting `Activity` or `Fragment`:

```java
List mSelected;

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE_CHOOSE && resultCode == RESULT_OK) {
mSelected = Matisse.obtainResult(data);
Log.d("Matisse", "mSelected: " + mSelected);
}
}
```
