Last path segment is not a resource ID: " + data.uri

Error message

Last path segment is not a resource ID: " + data.uri

What it means

In Utils.getResourceId(Resources, Request), a single-segment android.resource:// URI is interpreted as a raw numeric resource ID (Integer.parseInt of the one segment). If the segment is not a number (e.g. a bare resource name like 'ic_logo'), the NumberFormatException is caught and rethrown as FileNotFoundException('Last path segment is not a resource ID: <uri>') — the single-segment form only accepts IDs, not names.

Solutions

  1. Use the two-segment name form: android.resource://<package>/drawable/ic_logo.
  2. Or pass the decimal ID as a string: android.resource://<package>/2131099687 (String.valueOf(resId)).
  3. Best for local resources: pass the int directly via picasso.load(resId).

Example fix

// before
Uri uri = Uri.parse("android.resource://com.example.app/ic_logo"); // name, not ID
picasso.load(uri).into(imageView);

// after
Uri uri = Uri.parse("android.resource://com.example.app/drawable/ic_logo");
picasso.load(uri).into(imageView);
Defensive patterns

Strategy: validation

Validate before calling

Uri resourceUri(Context ctx, String type, String name) {
    return new Uri.Builder().scheme("android.resource")
        .authority(ctx.getPackageName())
        .appendPath(type).appendPath(name).build(); // 2-segment name form
}

Try / catch

Catch in error callback; the message includes the URI so mis-built segments are easy to spot in logs.

Prevention

When it happens

Trigger: Passing android.resource://com.example.app/ic_logo — a one-segment path containing a resource NAME instead of a number; passing a numeric string with whitespace or a '#'/hex prefix.

Common situations: Assuming the short form accepts names like the two-segment form does; passing Integer.toHexString(resId) or a formatted string ('res 2131099687') as the segment.
