Why image auto rotate when set to Imageview with Picasso
The problem issued here
Picasso auto rotates by 90 degrees an image coming from the web that has the following EXIF data:
Resolution : 3264 x 2448
Orientation : rotate 90
try this code with picasso:
Picasso.with(MainActivity.this)
.load(imageURL) // web image url
.fit().centerInside()
.transform(transformation)
.rotate(90) //if you want to rotate by 90 degrees
.error(R.drawable.ic_launcher)
.placeholder(R.drawable.ic_launcher)
.into(imageview)
});
You can also use Glide:
dependencies {
// Your app's other dependencies
compile 'com.github.bumptech.glide:glide.3.7.0'
}
laod image using:
Glide.with(this).load("image_url").into(imageView);
Try this way it will work
