PhotoViewAttacher not found on Android 4.2.2 ?

Hi !

I have CustomPhotoView component:

public class CustomPhotoView extends FrameLayout {

    private ImageView mDefaultImageView;
    private PhotoView mPhotoImageView;

    public CustomPhotoView(Context context) {
        super(context);
        init();
    }

    public CustomPhotoView(Context context, AttributeSet attrs) {
        super(context, attrs);
        treatAttibutes(context, attrs);
        init();
    }

    public CustomPhotoView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        treatAttibutes(context, attrs);
        init();
    }

    protected void treatAttibutes(Context context, AttributeSet attrs) {}

    protected void init() {
        // Create and setup image views
        mDefaultImageView = new ImageView(getContext());
        mPhotoImageView = new PhotoView(getContext());

    ...

I use the last PhotoView library: compile ‘com.github.chrisbanes.photoview:library:1.2.4’

It works perfectly on my S5 (Android 5.1), but on my Genymotion with Android 4.4.4 it’s failed on line:

mPhotoImageView = new PhotoView(getContext());

The error is: java.lang.NoClassDefFoundError: uk.co.senab.photoview.PhotoViewAttacher

Thank you very much for your help!

The problem was linked with multidex in my Gradle.

The correct way is to set in Gradle: // Enabling multidex support. multiDexEnabled true

And this in my Application class: @Override protected void attachBaseContext(Context base) { super.attachBaseContext(base); MultiDex.install(this); }
