Android at Mobile World Congress

I'm happy to announce that we'll be hosting a very special Android Developer Lab at Mobile World Congress (MWC) in Barcelona on Wednesday, February 17th as part of the inaugural App Planet event.

There will be technical presentations throughout the day and a developer lounge where you can talk to Android team members and meet others in the growing Android developer community.

Whether you’re already developing Android apps, you're an experienced mobile developer, or you’re considering making your first foray into writing mobile applications, the Android Developer Lab will provide access to the resources you need to create innovative and compelling apps for the Android platform.

Space is limited in the technical sessions, so if you're attending MWC and want to come by the Android Developer Lab, make sure to sign up now.

Also, we're offering a limited number of complimentary passes that provide access to the Android Developer Lab, the rest of App Planet, and the general exhibition areas for MWC. Sign up to be considered to receive a pass.

Hope to see you in Barcelona!

Android Developer Labs World Tour

Late last year, we held a series of developer labs to give you a chance to ask questions and play with some new hardware. One of the most common questions we received was, "When are you going to visit my city?" It's a good question, and we're pleased to answer it today.

The Android team is embarking on a world tour, which will include cities in Europe, North America, and Asia.

At each stop, we'll be delivering an update on the state of the Android platform—including a look at the latest Android hardware. It's a great opportunity to meet like-minded Android app developers, play with the latest Android devices, test your apps, and ask Android team members any questions you might have. You can find out more on the Android Developer Lab site.

Android at the 2010 Game Developers Conference

2009 has been a great year for Android Market. With the support of developers like you, Android Market now has more than 20,000 applications. Of these applications, games have proven to be particularly popular with Android users. Seven of the ten most popular paid applications on Android Market are games, so there's a significant opportunity for game developers as the number of Android devices continues to grow at a rapid pace.

To better support this trend, we are increasing our support of Android game development. As a first step, we will be presenting a number of Android sessions at the Game Developers Conference on March 9th and 10th in San Francisco. The sessions will be technical and will include everything you need to know about Android game development in Java or C++. Engineers from the Android team will also be available to answer your questions. Whether you are new to the platform or already have games in development, we would love to meet you face-to-face, answer your questions, and see what you're working on. Be sure to keep checking the GDC site because we'll be adding more sessions.

But that's not all. Google and GDC will also be providing complimentary Android phones to attendees who register for All Access or Tutorials and Summits passes by the Early Bird deadline of February 4, 2010. Qualified attendees will receive either a Nexus One or a Verizon Droid by Motorola, so they can quickly apply what they learn from the various Android sessions. You can find more details about the Android phone offer on the GDC site.

Our goal is to make it as easy as possible to develop awesome games for Android, and this is a first step. Hope to see you at GDC!

IRC office hours update


You may recall that we announced IRC Office Hours for Android app developers back in December. We just want to provide a quick update that upcoming office hours will be held on Thursdays from 5 p.m. to 6 p.m. PST, instead of twice weekly. These will be held in the #android-dev channel on irc.freenode.net as before.



Please post your questions on Stack Overflow with "from-irc" tag in addition to "android" tag one day before office hours. We will follow up on those specific questions during office hours, and will also post answers after.



We hope to see you there!

Android 2.1 SDK

Today, we are releasing the SDK component for Android 2.1, so that developers can take advantage of the new features introduced in Android 2.1. Please read the Android 2.1 release notes for more details. You can download the Android 2.1 component through the SDK Manager.

In addition to the new SDK, a new USB driver that supports Nexus One is also available today through the SDK Manager. The USB driver page contains more information.

Konversi Satuan Ukuran Luas

Satuan ukuran luas sama dengan ukuran panjang namun untuk mejadi satu tingkat di bawah dikalikan dengan 100. Begitu pula dengan kenaikan satu tingkat di atasnya dibagi dengan angka 100. Satuan ukuran luas tidak lagi meter, akan tetapi meter persegi (m2 = m pangkat 2).
  • 1 km2 sama dengan 100 hm2
  • 1 km2 sama dengan 1.000.000 m2
  • 1 km2 sama dengan 10.000.000.000 cm2
  • 1 km2 sama dengan 1.000.000.000.000 mm2
  • 1 m2 sama dengan 0,01 dam2
  • 1 m2 sama dengan 0,000001 km2
  • 1 m2 sama dengan 100 dm2
  • 1 m2 sama dengan 1.000.000 mm2
Cara Menghitung :
  • 1 hektar / ha / hekto are = sama dengan = 10.000 m2
  • 1 are = sama dengan = 1 dm2
  • 1 km2 = sama dengan = 100 hektar

    Konversi Satuan Ukuran Isi atau Volume

    Satuan ukuran luas sama dengan ukuran panjang namun untuk mejadi satu tingkat di bawah dikalikan dengan 1000. Begitu pula dengan kenaikan satu tingkat di atasnya dibagi dengan angka 1000. Satuan ukuran luas tidak lagi meter, akan tetapi meter kubik (m3 = m pangkat 3).
    • 1 km3 sama dengan 1.000 hm3
    • 1 km3 sama dengan 1.000.000.000 m3
    • 1 km3 sama dengan 1.000.000.000.000.000 cm3
    • 1 km3 sama dengan 1.000.000.000.000.000.000 mm3
    • 1 m3 sama dengan 0,001 dam3
    • 1 m3 sama dengan 0,000000001 km3
    • 1 m3 sama dengan 1.000 dm3
    • 1 m3 sama dengan 1.000.000.000 mm3
    Cara Menghitung :
    • 1 liter / litre = 1 dm3 = 0,001 m3

      Konversi Satuan Ukuran Berat atau Massa

      Untuk satuan ukuran berat konversinya mirip dengan ukuran panjang namun satuan meter diganti menjadi gram. Untuk satuan berat tidak memiliki turunan gram persegi maupun gram kubik. Contohnya :
      • 1 kg sama dengan 10 hg
      • 1 kg sama dengan 1.000 g
      • 1 kg sama dengan 100.000 cg
      • 1 kg sama dengan 1.000.000 mg
      • 1 g sama dengan 0,1 dag
      • 1 g sama dengan 0,001 kg
      • 1 g sama dengan 10 dg
      • 1 g sama dengan 1.000 mg
      Cara Menghitung :
        • 1 kuintal / kwintal = sama dengan = 100 kg
        • 1 ton = sama dengan = 1.000 kg
        • 1 kg = sama dengan = 10 ons
        • 1 kg = sama dengan = 2 pounds

          Konversi Satuan Ukuran Panjang

          Untuk satuan ukuran panjang konversi dari suatu tingkat menjadi satu tingkat di bawahnya adalah dikalikan dengan 10 sedangkan untuk konversi satu tingkat di atasnya dibagi dengan angka 10. Contoh :
          • 1 km sama dengan 10 hm
          • 1 km sama dengan 1.000 m
          • 1 km sama dengan 100.000 cm
          • 1 km sama dengan 1.000.000 mm
          • 1 m sama dengan 0,1 dam
          • 1 m sama dengan 0,001 km
          • 1 m sama dengan 10 dm
          • 1 m sama dengan 1.000 mm
          Cara Menghitung :
          • 1 inch / inchi / inc / inci = sama dengan = 25,4 mm
          • 1 feet / ft / kaki = sama dengan = 12 inch = 0,3048 m
          • 1 mile / mil = sama dengan = 5.280 feet = 1,6093 m
          • 1 mil laut = sama dengan = 6.080 feet = 1,852 km
          1 mikron = 0,000001 m
          1 elo lama = 0,687 m
          1 pal jawa = 1.506,943 m
          1 pal sumatera = 1.851,85 m
          1 acre = 4.840 yards2
          1 cicero = 12 punt
          1 cicero = 4,8108 mm
          1 hektar = 2,471 acres
          1 inchi = 2,45 cm
