Question

I’ve got a broadcast receiver that gets “android.intent.action.PACKAGE_ADDED” and “android.intent.action.PACKAGE_REPLACED” intents (so when a package is installed on the phone, my app gets an intent with the package name). But when I try to use the PackageManager to get the PackageInfo by package name, it’s throwing a NameNotFoundException.

What reasons might there be for this (other than the package not existing, which obviously isn’t the case)? I can’t find much on permissions – is there one I’m missing that’s causing a misleading error?

try {
    id = UAppIDUtils.GetUAppID(ctx.getPackageManager().getPackageInfo(pkgName, PackageManager.GET_SIGNATURES));
} catch (NameNotFoundException e) {
    id = null;
    Log.v(TAG, "Error finding package info");
    e.printStackTrace();
}

ctx is the context; pkgName is the package name.

Figured it out – it turns out that the string shipped with the PACKAGE_ADDED intent starts with “package:” and then the package name – I hadn’t caught it because it didn’t stand out in my print statements as something I hadn’t written. Just needed to strip the label off the start of the data string and I was good to go.
