I am trying to make an app which shows images from online database. but I want to use palette API to get vibrant color from each image. But I think I don't know how to use Bitmap decodeResource method OR Palette. please guide me how to use Bitmap factory.decoderResource with Palette in online URL or URI image file.
here is the method which I used in activity class recylceview subclass error shows in line number 171 "Bitmap is not valid":
170 Bitmap photo = BitmapFactory.decodeResource(getResources(), mCursor.getPosition());
171 Palette.generateAsync(photo, new Palette.PaletteAsyncListener() {
public void onGenerated(Palette palette) {
int bgColor = palette.getLightVibrantColor(getApplicationContext().getResources().getColor(android.R.color.black));
holder.placeNameHolder.setBackgroundColor(bgColor);
}
});
So here is the error:
10-29 17:39:42.067 31692-31750/com.example.xyzreader E/libEGL: load_driver(/system/lib/egl/libGLES_emulation.so): dlopen failed: library "/system/lib/egl/libGLES_emulation.so" not found

Sorry for late reply,
I forgotten to answer this question after solving problem. So here is the answer : I found Picasso API for Palette color and here is the code of Picasso API with Palette feature
Picasso.with(getActivity())
.load(mCursor.getString(ArticleLoader.Query.PHOTO_URL))
.into(Imagebar, new com.squareup.picasso.Callback() {
@Override
public void onSuccess() {
Bitmap bitmap = ((BitmapDrawable) Imagebar.getDrawable()).getBitmap();
if (bitmap != null) {
Palette.from(bitmap)
.generate(new Palette.PaletteAsyncListener() {
@Override
public void onGenerated(Palette palette) {
Palette.Swatch vibrantSwatch = palette.getDominantSwatch();
if (vibrantSwatch != null) {
bylineView.setBackgroundColor(vibrantSwatch.getRgb());
bylineView.setTextColor(vibrantSwatch.getTitleTextColor());
coordinatorLayout.setBackgroundColor(vibrantSwatch.getPopulation());
}
}
});
}
}
@Override
public void onError() {
Snackbar snackbar = Snackbar
.make(coordinatorLayout, "Error on image load.", Snackbar.LENGTH_LONG);
snackbar.show();
}
});
