[Android] Is this application system? Or whether the system is not.

gistfile1.java

final PackageManager pm = getPackageManager();

final List<ApplicationInfo> appInfos = pm.getInstalledApplications(Context.BIND_AUTO_CREATE);
for (final ApplicationInfo appInfo : appInfos) {

	// Determination of the bit flag.
	if( (appInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 1) {
		Log.d("ApplicationInfo[SYSTEM]",appInfo.toString());
	} else {
		Log.d("ApplicationInfo[NOT SYSTEM]",appInfo.toString());
	}
}
