看起來還不賴！

This application heavily uses OpenGL to render the scenes. It looks great on Nexus One. But 0xdroid does not yet support hardware accelerated 3D graphics and rely on libagl to rasterize the 3D graph.

Agl is the software OpenGL rendering engine used by android emulator. Gallery3D assumes there is hardware support and this caused a lot of trouble when one want to run it with agl. Even if the libagl implementation is correct and complete, Gallery3D may also assumes some implementation depended behavior. Not to mention the fundamental libagl implementations may have problems.

Anyway, we have some progress and I’d like to share the screenshots. Devkit8000 DVI output, 640×480 resolution, captured by DDMS.

I have a feeling there are more OpenGL tricks inside the source code then I’d expected.

這個 Provision 的動作其實就是 Device 第一次啟用時做初始設定，在 Google phone 上面就是 SetupWizard，在 emulator 裏面則有簡單的 Provision.apk，之前無法作用就是因為一直沒有把 Provision.apk 放進去…

Provision.apk 做了什麼事呢？其實很簡短：

public class DefaultActivity extends Activity {

    @Override
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);

        // Add a persistent setting to allow other apps to know
        // the device has been provisioned.
        Settings.Secure.putInt(getContentResolver(),
                               Settings.Secure.DEVICE_PROVISIONED, 1);

        // remove this activity from the package manager.
        PackageManager pm = getPackageManager();
        ComponentName name = new ComponentName(this,
                                     DefaultActivity.class);
        pm.setComponentEnabledSetting(name,
                   PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0);

        // terminate the activity.
        finish();
    }
}

因此若要提供一個類似 SetupWizard 的初始化介面在 Devit8000 上面，只要延伸這個 Provision.apk 做的事，提供 GUI 等等，最重要的就是設定這個 “Settings.Secure.DEVICE_PROVISIONED”

這是一個筆記。

What’s new in this release? The biggest one is that it is based on Éclair code base! While Éclair uses a lot more 3D stuff for its UI, the performance drop between Donut and Éclair is huge. After lots of testing and hacking, we finally bought the Éclair performance back to its original level. For detailed benchmark results, checkout the wiki page Benchmarks.

Second is new hardware support. 0xdroid now officially supports Devkit8000, a BeagleBoard clone. Developers did many works to bring up the all functionality include LCD/DVI output, touchscreen calibration, USB, Ethernet, etc. Running Éclair on Devkit8000 looks great!

Oh, and the new installer! The new installer used in this release supports both BeagleBoard and Devkit8000, with different display resolution and hardware revision. It can do a lot more than previous installer can do, for example it can download images from network, install to SD/MMC card and indicate progress via graphic display or via blinking LEDs. All of this will fit into a 1MB binary!

大伙興奮的開箱啦！

包裝和 Hero 的很像。3.2 寸 LCD, 480×320 的解析度，200 萬畫素的相機鏡頭，CPU 是 Marvell 300 (624 MHz)，記憶體是 256 + 128 MB，支援 WIFI, Bluetooth, FM, GPS。不是使用標準的 USB 接口，但同一個接口可以接 USB、耳機、變壓器。觸控螢幕使用起來的感覺像是電容式的，反應非常靈敏，輕輕的觸摸就有反應。

系統是 Android Cupcake，內建軟體有不少 Google App，最另人驚訝旳是上面有 Android Market 可以用，試著從 Market 上面下載了一些小遊戲下來玩，完全沒有問題，真是太牛了！另外一點就是有內建手寫輸入，速度不快但是準確度不錯。除此之外還有谷歌拼音可以用。

測試的途中無線網路與 GPS 不是很穩，除此之外以一隻中低價位的手機來說表現的相當不錯。

    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
    network={
            ssid="Example"
            psk="password"
            id_str="office"
    }

    network={
        key_mgmt=NONE
    }
    # 可以參考 /usr/share/doc/wpasupplicant/examples/wpa-roam.conf

然後在 /etc/network/interfaces 加加 mapping

    allow-hotplug wlan0
    iface wlan0 inet manual
            wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

    iface office inet dhcp

之後開機就會自動 connect 到合適的 AP 了

當然，如果有備份的話就沒什麼好說的了……，其實我有備份硬碟，只是該硬碟上的備份檔竟然無法 mount，superblock 全毀！！弄的我這次放五天假，一點都沒感覺有休息到 @@

松果要重新蒐集是還好，畢竟某些松果終究只是堆在那裡而已，照片什麼的別人手上都有備份，最糟糕的是 gpg key 了，比身份證掉了還麻煩，下次放假如果還是沒辦法把備份檔拿出來，應該就一個個重簽了 Orz

損失了幾篇文章以及一些 comments，不過還好損失的文章都從 planet 找回來了

comments 我就留在信箱裡吧

前幾天和小良去墾丁玩，現在是半個黑人~
