SELinux on Android

niels — Sat, 14 Jan 2012 14:41:38 +0000

SELinux is coming to Android. Called SEAndroid, the project looks pretty interesting:

Some distinctive features of our SE Android reference implementation in comparison to prior efforts of which we are aware include:
Per-file security labeling support for yaffs2,
Filesystem images (yaffs2 and ext4) labeled at build time,
Kernel permission checks controlling Binder IPC,
Labeling of service sockets and socket files created by init,
Labeling of device nodes created by ueventd,
Flexible, configurable labeling of apps and app data directories,
Userspace permission checks controlling use of the Zygote socket commands,
Minimal port of SELinux userspace,
SELinux support for the Android toolbox,
Small TE policy written from scratch for Android,
Confined domains for system services and apps,
Use of MLS categories to isolate apps.

Comparison of Java Serialisers

The JVM Serialisers project provides a very extensive comparison of dozens of different JVM serializers out there. Tested tools include several JSON libs, different XML related libs, Scala, protobuf, protostuf, msgpack and many more.
I didn’t know protostuff before – it seems to be really amazing!

Android: Get String From Resource By Name

niels — Sun, 29 Nov 2009 16:54:58 +0000

Usually the string resources in your Android application are being referred to by a unique ID. But sometimes you will want to recover a string by its key, e. g. when you build the key of the string at the run time of your application (“Battery_Health_2″ or “Battery_Health_3″). You can do that like this:

private String getStringResourceByName(String aString)
{
  String packageName = "com.coliena.myapp";
  int resId = getResources().getIdentifier(aString, "string", packageName);
  return getString(resId);
}

Check this link if you need to recover an image resource by its name.
More information about string resources is available in the Android Developer Documentation.
