Why can't picasso load my url? Always defaulting to onError.

问题

Here is the onCreate of myActivity thats gonna use picasso:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        String url = "http://s3.amazonaws.com/snappie.watermarks/crssd.png";
        sticker = (ImageView)findViewById(R.id.sticker);
        Picasso.with(getApplicationContext()).setLoggingEnabled(true);

        FrameLayout camera_layout =(FrameLayout)findViewById(R.id.fragment_container);
        previewWidth = camera_layout.getWidth();
        Log.d("width","width is"+previewWidth);
        Picasso.with(this).load(url).into(sticker,new Callback() {
            @Override
            public void onSuccess() {
                myBitmap = ((BitmapDrawable) sticker.getDrawable()).getBitmap();
                int width = (myBitmap.getWidth() * previewWidth) / 1080;
                int height = (myBitmap.getHeight() * previewWidth) / 1080;
                scaledBitmap = Bitmap.createScaledBitmap(myBitmap, width, height, false);
                sticker.setImageBitmap(scaledBitmap);
                //saveBitmap(myBitmap);
            }

            @Override
            public void onError() {
                Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.balloons);
                sticker.setImageBitmap(bm);
            }
        });

    }

It pretty much always defaults to the balloons (from onError).

Here is the log:

If you try the url manually you can tell that it is real and exists. So what is going on here?

回答1:

it looks good, you probably missed the internet use-permission. Add

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

to your AndroidManifest.xml
