Thoughts about Android Marshmallow 6.0 Permission model

I hope it is the rumored granular permission mode. But if it resembles anything in this SMH article, then it sounds like JavaME permission model all over again :p

Marshmallow also streamlines the “permissions” model for users to install and upgrade apps.
Users running certain apps will not need to grant any permissions when they install or upgrade, and the applications instead request permissions as it needs them.

Checking if website is Mobile-Friendly

Google has announced that they will take Mobile-Friendly site into account when indexing sites. Thus, it is prudent to ensure the particular website that you’re maintaining is mobile friendly.

There are two main tools released by Google for testing if the website is Mobile-Friendly:

  1. Google Mobile Friendly Test
  2. PageSpeed Insights

However, personally I like PageSpeed Insights tool better because it gave more in-depth explanation on how to improve my site.


Have fun trying out.

How to convert between sqlite2 and sqlite3 database

Here’s a short guide on how to convert between sqlite2 to sqlite3 database file:

sqlite2 /path/to/mysqlite2.db .dump > backupfile
sqlite3 /path/to/mynewsqlite3.db < backupfile

Using the same method, you can convert sqlite3 db to sqlite2 db too!

p/s: Why you need to convert? because embedded device (read: iPhone and Android) only supports sqlite3 database, while PHP 5 by default supports sqlite2 database.

Thus, this method provide a convenient way to convert between the two different version of sqlite db format.

My new Android app development machine – running on Ubuntu Precise

I always wanted a smooth development machine which can run multiple virtual machine (VM) at once, which is a must when testing app that is meant to be portable across different platform. So just before Ramadhan (in July), I bought 8GB RAM and 1TB hdd from a local pc shop and proceed to set-up my development machine.

The machine already has 4GB ram so adding the extra RAM bumped it to 12GB. The machine I was running is an older Intel Core i5, which is decent enough to execute all the VM that is necessarily when developing and testing the app.


with all those RAM, seems it’ll be quite a while before I use the swap space again.

How to set the correct Android *.apk MIME Type for Apache Webserver

Android application uses *.apk file as its installation package. It is a variant of the Java JAR file format (which in turn a Zip 2.0 file). Usually the *.apk file is obtained from Android Marketplace, the official channel for getting Android application. However there are some vendors or carriers that allow *.apk file to be downloaded from 3rd-party websites.

Those who elect to upload the *.apk files on their own webserver can add the official Android APK MIME Type to their Apache Web server config file:

Option 1: edit mime.types (for those who have root access)
1. First edit the mime.types file – sudo nano /etc/apache2/mime.types
2. Then add this at the end of the file – application/
3. Reload the server configuration – “sudo service apache2 reload”
Option 2: edit .htaccess file (for shared server or user who do not have root access)
1. Edit .htaccess
2. Add this line – AddType application/

This will register the appropriate MIME type for the *.apk file so that both the server and mobile application can handle.
