| 2 | Greenstone3 Runtime on Android
|
---|
| 3 | ==============================
|
---|
| 4 |
|
---|
| 5 | This extension helps you set up and run Greenstone3 on your android device.
|
---|
| 6 |
|
---|
| 7 | It relies on the environment variable ANDROID_SDK_HOME to determine
|
---|
| 8 | where Android's SDK lives on your file system (primarily to be able to
|
---|
| 9 | run 'adb' and 'dex'). If this is not set prior to running the scripts
|
---|
| 10 | this extension provides, it can be set explicitly in setup.bash/bat.
|
---|
| 11 |
|
---|
| 12 | Having sourced the setup file the two main steps are:
|
---|
| 13 |
|
---|
| 14 | 1) Install i-jetty
|
---|
| 15 |
|
---|
| 16 | 2) Install Greenstone3 as a web-app
|
---|
| 17 | (converting any jar and class files to DEX format)
|
---|
| 18 |
|
---|
| 19 | The first step typically only needs to be done once. The second step is
|
---|
| 20 | composed of three sub-steps, and may require the last two sub-steps to
|
---|
| 21 | be repeated if the Java code is changed.
|
---|
| 22 |
|
---|
| 23 | Step 1
|
---|
| 24 | =======
|
---|
| 25 |
|
---|
| 26 | First, install i-jetty on your Android device. You can do this through
|
---|
| 27 | the Market, or else type:
|
---|
| 28 |
|
---|
| 29 | adb install i-jetty-2.2-signed.apk
|
---|
| 30 |
|
---|
| 31 | Note: for your Android device to install applications using 'adb' you
|
---|
| 32 | need to have enabled it's application 'Development' mode (under
|
---|
| 33 | Settings->Application)
|
---|
| 34 |
|
---|
| 35 |
|
---|
| 36 | Step 2
|
---|
| 37 | ======
|
---|
| 38 |
|
---|
| 39 | Next put your Android device into USB disk mode, and set up the necessary files
|
---|
| 40 | to run Greenstone3 as a web-app under i-jetty. The three sub-steps are:
|
---|
| 41 |
|
---|
| 42 |
|
---|
| 43 | Step 2.1
|
---|
| 44 | --------
|
---|
| 45 |
|
---|
| 46 | Transfer the bulk of the <GSDL3SRCHOME>/web structure to the
|
---|
| 47 | <SDCARD>/ijetty/webapps/greenstone3 with:
|
---|
| 48 |
|
---|
| 49 |
|
---|
| 50 | WEBAPP-ROOT-TO-SDCARD.sh
|
---|
| 51 |
|
---|
| 52 | This script skips any .svn files if present. It also skips installing
|
---|
| 53 | 'localsite' as this is rather large -- both in size and in terms of
|
---|
| 54 | the number of files invovled -- so copying is rather slow, and it is
|
---|
| 55 | probably not what you want anyway.
|
---|
| 56 |
|
---|
| 57 |
|
---|
| 58 | Step 2.2
|
---|
| 59 | --------
|
---|
| 60 |
|
---|
| 61 | Convert the class files (includes those stored in jar files) into
|
---|
| 62 | classs.dex with:
|
---|
| 63 |
|
---|
| 64 | JAVA-TO-DEX.sh
|
---|
| 65 |
|
---|
| 66 | The finished file, which is also by this point zipped up, is left in
|
---|
| 67 | the 'lib' folder.
|
---|
| 68 |
|
---|
| 69 |
|
---|
| 70 | Step 2.3
|
---|
| 71 | --------
|
---|
| 72 |
|
---|
| 73 | Copy classes.zip onto the Android's sd-card
|
---|
| 74 |
|
---|
| 75 | DEX-TO-SDCARD.sh
|
---|
| 76 |
|
---|
| 77 | This is the final step in getting Greenstone3 setup on an Andoird.
|
---|
| 78 | Switch off the USB disk mode on the Android device. Note: it can take
|
---|
| 79 | a device minute or two "preparing" the sd-card. This can be seen
|
---|
| 80 | on the notification view. Alternativey, if you try to start i-jetty
|
---|
| 81 | before the card is ready, then i-jetty points this out, and offers you
|
---|
| 82 | a 'retry' button.
|
---|
| 83 |
|
---|
| 84 |
|
---|
| 85 | Step 3
|
---|
| 86 | ======
|
---|
| 87 |
|
---|
| 88 | Launch i-jetty from my apps area. Then, within i-jetty, start the
|
---|
| 89 | server. Once the "Jetty started" message appears, switch to your
|
---|
| 90 | web-browser application. We've tested the built-in web browser, and
|
---|
| 91 | Mobile Firefox 4.
|
---|
| 92 |
|
---|
| 93 |
|
---|
| 94 | If the Java code to Greenstone3 is changed, then you need to repeat sub-steps
|
---|
| 95 | 2.2 and 2.3
|
---|
| 96 |
|
---|
| 97 |
|
---|
| 98 |
|
---|
| 99 | Caveats:
|
---|
| 100 | ========
|
---|
| 101 |
|
---|
| 102 | 1. Due to difficulties in getting MG and MGPP working on android
|
---|
| 103 | through the NDK, these are currently not supported. Effectively,
|
---|
| 104 | the Greenstone3 used needs to be one compiled *without* JNI
|
---|
| 105 | support.
|
---|
| 106 |
|
---|
| 107 |
|
---|
| 108 | 2. Due to a runtime (reflection) error, we had to modify xalan.jar.
|
---|
| 109 | The modified version of this file is also in the 'jars' folder
|
---|
| 110 | used in this extension.

---|
