Today is a day to be joyful for science-minded Android users. Wolfram Alpha has just released a ton of new science and math calculation apps in Google Play. They run the gamut from basic fractions and pre-algebra all the way up to materials science and astronomy. Wolfram Alpha previously released similar calculus and algebra course assistants.
Update: The issue (#10230007) has been marked as resolved by the Play Store team. Apps should install and update fine now.
For the last week or so, a great number of Android users have become increasingly frustrated with frequent "Package file is invalid" errors when updating or installing apps. A variety of supposed fixes have been put forward by the community, but have proven to be merely placebos. Now Google has confirmed there is an issue.
It took us a little longer than usual this time, but we're finally back with a short selection of last month's best new apps. It wasn't easy to narrow them down, but those readers who don't have time, spare cash, or patience enough for our longer semi-weekly roundups can't go wrong with the five apps we've chosen. If, by some chance, none of the apps below suit your fancy, we've got plenty of runners up too.
This is the app roundup. The game roundup from last week can be found here.
Bitcoin is still emerging as an online currency, and that means issues are sure to pop up in the way it's implemented. This time there's an Android-specific problem. It turns out there's a weakness in the way Android generates random secure numbers (the Java SecureRandom class), which most Bitcoin apps use to create wallet IDs. That means an attacker could possibly figure out your wallet key and swipe your digital cash.
How much would you pay for an Android security suite that may occasionally be of use? Maybe $1.99? $4.99? How about $149.00? No? Well, that's what Kaspersky Lab is currently asking for its Mobile Security app in Google Play. Got a lot of cash to burn and very little common sense? Kaspersky Tablet Security is only $199.00. What?
See, the apps for phones and tablets used to cost $4.95 and $9.95, respectively.
