Learning about Best Practices on Java EE Performance Testing.

Hang on guys, we’re moving to a new office in the Ortigas area. We’ll keep you posted!

I was trying to look for people who have successfully connected their MID Android Tablets to internet using broadband USB’s. A vain attempt pushed me to try it for myself. I hope this article saves you that 3 hours I spent squeezing Google for the solution.

1. Connect your SmartBro USB to the USB terminal adapter that came with your device
2. Go to “Settings”
3. Choose “Wireless Controls”
4. Tap “3G Network Settings”
5. Then “Add 3G Network”
6. Enter the following for SmartBro USB (haven’t tried it with Globe Tattoo USB, but I’m pretty sure it will also work – your misfortune if it doesn’t)

Name: SmartBro (I suggest you use a more descriptive name for easy identification)
Device: Scroll down to whichever says “HUAWEI” mine looked like this – WCDMA (HUAWEI E220/E230/E169G/E160X/E1750) (Again this is for SmartBro – Make sure you have connected the SmartBro USB)
Phone number: *99#
APN: internet
User: Leave this blank
Password: Leave this blank as well

7. Click connect!

Sorry for the crappy images!
Once it successfully connects to the SmartBro 3G Network, you should see the “3G” icon in the status bar of your device.

BTW, don’t forget to disconnect your connection.

Below is the code for creating a multiple options dialog in Android. This dialog is triggered by clicking an option from a context menu in my application and determine which Activity class my app should direct to.

…
final String items[] = {“Movie”,”Music”,”Book”};

AlertDialog.Builder ab=new AlertDialog.Builder(SmugActivity.this);
ab.setTitle(“Dialog Title”);
ab.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface d, int choice) {
if(choice == 0) {
Intent mainIntent = new Intent(SampleActivity.this, MovieActivity.class);
SampleActivity.this.startActivity(mainIntent);
SampleActivity.this.finish();
}
else if(choice == 1) {
Intent mainIntent = new Intent(SampleActivity.this, MusicActivity.class);
SampleActivity.this.startActivity(mainIntent);
SampleActivity.this.finish();
}
else if(choice == 2) {
Intent mainIntent = new Intent(SampleActivity.this, BookActivity.class);
SampleActivity.this.startActivity(mainIntent);
SampleActivity.this.finish();
}
}
});
ab.show();
…

The code above should look like this:

You can also make the option items appear as radio buttons by using the “setSingleChoiceItems” method of the AlertDialog.Builder class instead of setItems. To add an “OK” and “Cancel”, add the code below inside the DialogInterface.OnClickListener()

…
.setPositiveButton(“Ok”, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface d, int choice) {
// on OK button action
}
})
.setNegativeButton(“Cancel”, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface d, int choice) {
// on Cancel button action
}
})
…

With additional code our multiple options dialog should now look like this:

I got this error(Unparsed aapt error – triggered by another error – “Invalid filename: must contain only [a-z0-9_.]“) when I modified a resource XML file in my Android project. After fixing the problem that triggered this “Unparsed aapt error”, I was expecting that my code is ready to be deployed in my device. After going around, blindly searching for other might-be problems in my XML resources. I knew I had to run Eclipse’s debug. And it just won’t work. I realized that at this point, Eclipse wasn’t able to identify anymore that the problem has already been solved. I right clicked on the error in Eclipse’s “Problems” view and deleted the error manually.

Modified my code and saved – just to force a “build”. Ran my code in my device – Problem solved!
