Howto: Enable Autorotate for your G1 Browser!

I'm not sure why the Android Browser doesn't auto rotate by default. Instead they have a "Flip Orientation" menu item that lets you toggle your default orientation. Pretty useless overall. Anyhow, a quick hack in the Browser source code let me enable auto rotation via the G-Sensor.

The change is really trivial. In the BrowserActivity.onCreate, I hard coded the orientation to ActivityInfo.SCREEN_ORIENTATION_SENSOR instead of pulling it from a preferences setting.

The downside is that the flip orientation menu item no longer works. Not that I care: I (and probably most people) never used it. So it is a hack, but oh well. If I'm motivated I'll put in a proper fix.

Installation Instructions (you must have root access):

  • Download the updated Browser.apk
  • Run the following from the command prompt to back up your current Browser file to your sdcard and install the new one:
    • adb remount
    • adb pull /system/app/Browser.apk BrowserBackup.apk
    • adb push BrowserBackup.apk /sdcard
    • adb shell rm /system/app/Browser.odex
    • adb push Browser.apk /system/app

  2. Seems like using the flip orientation button actually causes the autorotate to stop working until a restart? anyone else experience this?

  5. WTF. It won't let me copy the new Browser.apk over.

    failed to copy 'c:/temp/Browser.apk' to '/system/app/Browser.apk': No space left on device

    somehow it deleted the Browser.apk and then filled the space or resized the partition in system so that I can't put back the new Browser.apk....

    e-mail me at odslabs@gmail.com if you can help, thanks.
