Google Reader Android app

The official Google Reader application for Anrdoid is finally here. For me, this is really good news, since I have been hesitant to install applications such as NewsRob for security reasons.

Yet another Android security vulnerability

Android security holes seem to be pouring down from the skies nowadays. This new vulnerability allows a malicious website to access files located on your SD card.

More Android exploits

As I pointed out in a previous post, Android is, if used incorrectly, just as insecure as any normal PC. After writing that post, a few reports on exploitable vulnerabilites in Android has surfaced.

There seems to be a bug in the credentials manager, which can be exploited to install applications without the users approval: (In Swedish) (Also in Swedish)

There is also a vulnerability in the browser in most Android phones on the market today:,android-exploit-code-published.aspx

In addition to this, on November 2, Coverity Inc., famous for its array of various code analysis software, published a report about a number of potential security issues in the Linux kernel used in Android:

So, as already pointed out: Be careful about which applications you download and which web sites you visit with your Android phone (or any network capable device, for that matter)!

Encoding videos for Android with mencoder

I have a Sony Ericsson X10 which I watch a lot of videos on, mainly in bed before I go to sleep. While I mostly watch YouTube clips and such, sometimes I watch episodes of TV series which I put on the SD card. Unfortunately, Android doesn’t willingly play the normal PC video formats, and especially not H.264 encoded HD files, so I need to reencode the files to MPEG4.

Previously, I have been using FFmpeg to reencode my videos, mostly due to its relatively simple command line syntax. Today, I wanted to try mencoder instead, because I really like the flexibility it delivers. I don’t know if FFmpeg has the same features; at least I haven’t found them. I struggled a bit before finding good parameters to create a video file which Android can actually play. In the end, I settled for this command line:

mencoder -o test.3gp -ovc lavc -oac lavc
 -lavcopts vcodec=mpeg4:acodec=libfaac:vbitrate=800:abitrate=192:vglobal=1:aglobal=1
 -of lavf -lavfopts format=3gp -noskip -noautoexpand -vf dsize=854:480:0,scale=0:0,harddup
 -af channels=2,volnorm test.mkv

This can probably be tweaked to produce files which suit you better, but at least it’s a start.

Is Android secure?

There’s been a lot of talk lately in swedish media about the security of smart phones. This news report (in swedish) by the swedish public service TV station SVT shows how easy it is to hack into your iPhone and do all kinds of weird stuff, such as recording audio using the phone’s microphone or sending an SMS.

Following that report the well known swedish Android site Swedroid published an interview (also in swedish) about the security of Android. This post is written in response to that interview.

Paid Android apps in Sweden

Yay! Finally Google managed to bring paid apps to the swedish Android Market. I honestly don’t know what took them so long, but it’s good that it’s here, so that I can start earning some money from my apps.

Time to get busy! :)
