Picasso doesn't load view in MainActivity

Question

I'm doing a basic Android Studio Project for loading a URL into an ImageView using Picasso with Kotlin. I have followed every step from the official webpage of Picasso, but when I run my app the emulator shows an empty view.

In my Gradle I added the implementation of Picasso:

implementation 'com.squareup.picasso:picasso:2.71828'

And Internet permission within manifest tag too:

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

And in MainActivity the basic use of Picasso:

Picasso.get().load("http://paproject.online/hp.jpg").into(imageTest)

imageTest is the id of a Imageview with layout_height = 200dp and layout_weight = 200dp.

and If U can Change Picasso with Glide. maybe Can help you

I'm trying Picasso because Glide didn't work me at the first time too. – piedra97 Mar 26 '19 at 18:07

Your image is larger (1024x768) than your ImageView, but of course that should not be a reason for you to get blank. Try as below which also includes local image resource nopic for the error cases. Seems you have the correct include

// Lazy load the image with Picasso
get()
        .load(yourURL)
        .placeholder(R.drawable.nopic)
        .error(R.drawable.nopic)
        .into(img);

Ok, I just added what you told me and now is loading the drawable that is place in placeholder instead of the URL image. In my Logcat doesn't appear any error. – piedra97 Mar 26 '19 at 10:19

You can resize your image before including it into imageView

Picasso  
.with(context)
.load("http://paproject.online/hp.jpg")
.resize(200, 200) // resizes the image to these dimensions.
.into(imageViewResize);

Or you can use any cropping technique like .CenterCrop(). You can read more about this https://futurestud.io/tutorials/picasso-image-resizing-scaling-and-fit

I prove all you say but still having an empty view. – piedra97 Mar 26 '19 at 14:24
You can activate the logs by calling .setLoggingEnabled(true) on your Picasso instance and view all Picasso request on Android logcat – Juan Rodríguez Mar 26 '19 at 16:34

Ok, the problem is already solve. It seems that there is a problem loading images in Android 9.0. So the solution is in this link: Picasso image loading issue with Android 9.0 Pie. Thanks to everyone for your responses.
