I do not support this anymore, it is only for showcase. I recommend to use Glide, Picasso or Fresco.

Deco

Deco is tiny library for android image loading and caching. Not use any 3rd party library, it has zero dependencies. It has a 18,6 kB size and has 143 methods only.

What it can do

• can cache dowloaded images to private storage or to application-specific directory on the primary shared/external storage
• can set cache size if the app needs more
• can set cache policy, there is 3x type
• can set read and connection timeout for all images
• can crop image to circle and can set relative position too
• can crop image to rounded cornered rectangle with different corners
• can add a stroke to the image
• can add custom http headers for downloading
• all the options can be setted for one image or for all images
• tint mode
• almost everything can be set from xml as well

Requirements:

Android api 4.3+ and permissions:

<uses-permission android:name="android.permission.INTERNET" />

Add to dependencies:

compile 'com.github.gerp83:Deco:1.02'

Examples

Simple loading, you also set for every image:

• corners for rectangle crop
• crop to circle with relative position
• stroke width and color
• tint and color
• cache policy
• http headers
• trust all https

@Override 
public void onCreate(Bundle savedInstanceState) {
  
  ImageView imageView = (ImageView) findViewById(R.id.imageView);
  imageView.get("http://some_image_url");
}

From XML you can set: cropToCircle, circlePosition, topLeftCornerRadius, topRightCornerRadius, bottomRightCornerRadius, bottomLeftCornerRadius, stroke_color, stroke_width tintedMode and tintColor.

<com.gerp83.deco.DecoView
  android:id="@+id/decoView"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:adjustViewBounds="true"
  android:scaleType="centerCrop"
  android:layout_margin="30dp"
  app:tintedMode="true"
/>

With DecoOptions you can set options for all the images. Options:

• storage type
• cache size
• read and connection timeout
• switch exception logs on/off
• call all https trusted
• add http headers
• cache policy

public class TestApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        DecoOptions.getInstance(getApplicationContext())
                .setImageSizeBound(getApplicationContext(), 1024)
                .setConnectionTimeout(getApplicationContext(), 30000)
                .setReadTimeout(getApplicationContext(), 10000)
                .setExceptionLogs(getApplicationContext(), false)
                .setCacheSize(getApplicationContext(), DecoOptions.DEFAULT_CACHE_SIZE)
                .setCachePolicy(getApplicationContext(), DecoOptions.CACHE_POLICY_NORMAL)
                .setStorageType(getApplicationContext(), DecoOptions.STORAGE_EXTERNAL);

    }

}

Planned updates:

• gif and/or webP support
