Android PackageManager No package identifier when getting value for resource number 0x00000000

When using the PackageManager to get a list of applications from the device, if i call pm.getApplicationIcon(app); and the application does not have an icon, the system will return the system default as it's supposed to do, but i get this error output in my console:

W/ResourceType: No package identifier when getting value for resource number 0x00000000
W/PackageManager: Failure retrieving resources for com.google.android.gsf.login: Resource ID #0x0

Since i'm looping through all applications on the phone, this turns into some pretty bad spam that I'd like to avoid if possible.

My Code

PackageManager pm = getActivity().getApplicationContext().getPackageManager();

for (ApplicationInfo app : pm.getInstalledApplications(0)) {
    long dataUsed = ((TrafficStats.getUidRxBytes(app.uid) + TrafficStats.getUidTxBytes(app.uid)) / 1000) / 1000;

    if ((int)dataUsed > 0) {
        String name = pm.getApplicationLabel(app).toString();
        Drawable icon = pm.getApplicationIcon(app);

        // Custom object
        DataUsageItem item = new DataUsageItem(name, icon, false, dataUsed, new int[]{ 0 , 0 , 0 , 0 , 0 , 0 , 0 });
        items.add(item);
    }
}
Solution

  • The ApplicationInfo for each will have an icon field that holds the resource ID for that drawable in the given package. Check that it's nonzero before calling getApplicationIcon().

    For those packages that do not have an icon – i.e., those whose icon field is zero – you can retrieve the system default icon with the android.R.drawable.sym_def_app_icon ID.
