Failed to obtain context or unrecognized Uri format for: {so

Error message

Failed to obtain context or unrecognized Uri format for: {source}

What it means

IllegalArgumentException thrown by ResourceDrawableDecoder.findContextForPackage() when context.createPackageContext(packageName) throws NameNotFoundException and the requested package is not a parent of the current app (i.e. not a split). Glide cannot obtain a Context to load resources from an uninstalled or unknown package.

Solutions

1. Verify the target package is installed via PackageManager.getPackageInfo(name, 0) before loading.
2. Use the current app's package name when loading your own resources.
3. Provide an .error() drawable fallback for uninstalled packages.
4. For dynamic feature modules, ensure the module is installed before requesting its resources.

Example fix

// before
Uri uri = Uri.parse("android.resource://com.other.app/drawable/icon");
Glide.with(ctx).load(uri).into(img);
// after
try {
  pm.getPackageInfo("com.other.app", 0);
  Glide.with(ctx).load(uri).into(img);
} catch (NameNotFoundException e) {
  img.setImageResource(R.drawable.default_icon);
}

// Confirm the package is installed before loading its resources.
try {
  ctx.getPackageManager().getPackageInfo(packageName, 0);
  // safe to load
} catch (PackageManager.NameNotFoundException e) {
  // fall back
}

try { Glide.with(ctx).load(uri).into(img); }
catch (IllegalArgumentException e) {
  if (e.getMessage() != null && e.getMessage().startsWith("Failed to obtain context")) {
    img.setImageResource(R.drawable.default_icon);
  } else throw e;
}

When it happens

Trigger: Loading an android.resource:// Uri whose authority names a package that is not installed and is not the current app or a split of it.

Common situations: Loading another app's icon (e.g. com.android.camera2) when that app is not installed. Hardcoded package names that drift across OEM builds. Loading resources from an uninstalled dynamic feature module.
