Android: install .apk programmatically (without user prompt)

Posted on January 21, 2012 by kanatorn

This note we need to create Android Application that has auto update feature for our android application. We do that for PandaBoard and other device that rooted.

1. Install BusyBox (for PandaBoard you can copy binary from BusyBox and paste to /system/bin/busybox) (for general device you can install BusyBox from Android Market)

2. set permission /data/app to 777 (some time you need to set 777 permission for /system/bin/busybox)

3. Make your own application that contained this code


Process install;

try {

install = Runtime.getRuntime().exec("/system/bin/busybox install " + Environment.getExternalStorageDirectory() + "/Download/" + "XXX.apk /data/app/XXX.apk");

int iSuccess = install.waitFor();

Log.e("TEST", ""+iSuccess);

} catch (IOException e) {

} catch (InterruptedException e) {

}

4. Run and Enjoy it!!

FQL COUNT Operator

Posted on January 3, 2012 by kanatorn

NO WAY!

There is not COUNT Operator for FQL.

But we can optimize query for count some thing.

Example:

SELECT ” FROM like WHERE post_id=”xxxxxxx”

This query return the smallest array, the number of json array is the number of post likes.

Posted on December 28, 2011 by kanatorn

Problem : AndEngine Live Wallpaper Extension cannot detect the home screen virtual page is changed (offset change)

Solved : Modify code of BaseWallpaperGLEngine in BaseLiveWallpaperService.java

  • Duplicate BaseLiveWallpaperService and change class name (I change to MyBaseLiveWallpaperService), change inner class BaseWallpaperGLEngine to MyBaseWallpaperGLEngine
  • Override method onOffsetsChanged in MyBaseWallpaperGLEngine

Facebook FQL “Like” Operator

Posted on November 15, 2011 by kanatorn

FQL ไม่มี “Like” Operator เหมือนใน SQL แต่สามารถใช้ STRPOS แทนได้ ดังตัวอย่าง

SELECT name from place WHERE strpos(lower(name),lower(‘สยาม’)) >=0

จากตัวอย่างจะเทียบได้กับ SQL

SELECT name from place WHERE name LIKE ‘%สยาม%’

				+ "') FROM place WHERE distance(latitude, longitude, '" + lat + "', '" + lon + "') < "+ distance +"  LIMIT " + limit + " OFFSET " + offset);

		ArrayList<PlaceModel> placeList = new ArrayList<PlaceModel>();
		String response = null;
		try {
			response = facebook.request(params);
			JSONArray jsonArr = new JSONArray(response);

				place.latitude = jsonObj.getDouble("latitude");
				place.longitude = jsonObj.getDouble("longitude");
				place.checkInCount = jsonObj.getInt("checkin_count");
				place.distance = jsonObj.getDouble("distance_meters");
				placeList.add(place);
			}
			return placeList;
		} catch (MalformedURLException e) {
			Log.e("Example", "ERROR", e);
			return placeList;
		} catch (IOException e) {
			Log.e("Example", "ERROR", e);
			return placeList;
		} catch (Exception e) {
