Android :: Optimized Way To Open URL (New Activity)

Aug 10, 2010

Wondering if anyone knows the most optimized way to handle opening an URL in android. Here is how I am doing it:

String tempUrl = helper.getUrl(tempString);
Intent i = new Intent("android.intent.action.VIEW", Uri.parse("http://"+tempUrl));
startActivity(i);

Must you start a new activity in order to open a URL?

Android :: Open Dialogue Activity Without Opening Main Activity Behind It

Jul 19, 2010

Im writing a program that offers a quick reply dialog upon receipt of an SMS.

However, I am getting an unexpected result. When I receieve an SMS, the appropriate dialog activity comes up displaying the correct phone number and message, however there is a second activity behind it that is the 'default' activity in my program (it is what opens when i launch my application)

I do not want this second activity to come up. The quick reply activity should come up by itself over top of whatever the user was doing before.

The 'floating' activity:

CODE:.........

The call to the activity inside an onReceive()

CODE:..............

The Manifest:

CODE:.................

Android :: How To Open Another Activity Within Application?

May 27, 2010

I understand how to use intents and startActivity() when opening another activity within my own app, but how do you start a different app? specifically:

- How do you determine if the user has the needed app installed on their device?
- How do you start that app?
- How do you pass parameters to that app?
- How do you find all this info out for a specific app (say Adobe reader, or google maps)?

General :: Making Apple Optimized Headset Mic Work On Android?

Aug 15, 2011

I just got my pair of UE600vi earbuds with a mic and in-line controller.

Everything works as expected (so no volume control), but what I didn't expect was that the built-in mic doesn't seem to work properly. When the cable is plugged in properly I get audio in a call, but the person on the other side of the line says he can't hear anything.. However, if I take the plug out a bit so that one black ring is out of the plug the mic seems to work,(probably because the mic is disabled and it uses the phone mic..) but I only get audio to one earbud.

I contacted Logitech which said that they can do nothing and that it's Android's problem.. However some people say that they've had no problems with apple-optimized headsets apart from the volume buttons.

Android :: How To Make Launcher Open Main Activity?

May 26, 2010

I have activities A and B. The A is the one with LAUNCHER intent-filter (i.e. the activity that is started when we click the app icon on home screen). A launches B using start Activity(new Intent(A.this, B.class)). When the user has the B activity open, and then put my application into the background, and later my application's process is killed, when the user starts my application again, B is opened instead of A. This caused a force close in my app, because A is the activity that initializes the resources my app needs, and when B tried to access the uninitialized resources, B crashes.

Android :: Application Optimized For High DPI Screen But Supporting Only Small / Medium

Aug 18, 2010

I'm building a game with graphic assets in hdpi resolutions (hence I put the files in drawable-hdpi directory). I don't want to have a corresponding mdpi resolution of the images, and I will code everything in 240-dpi based pixel coordinates.

Is it possible to still allow mdpi and ldpi devices to run the application, by automatically scaling the graphics from the hdpi version? Optimize for high-dpi devices only but still support (small- and) medium-dpi screens.

Motorola Droid :: Official 2.1 Release Is Going To Be Very Optimized ROM / Kernel

Jan 29, 2010

One thing some of you over-clockers may not be aware of is, the over-clocked kernel that you flashed to your DROID is based off of the 2.0 kernel. Some folks are reporting issues again that were present before the 2.0.1 update i.e. crackling audio, LED and keyboard back-lighting dysfunction, etc. Actually, I have yet to experience any of these issues.

This isn't bad news, mind you. Just a little something that we can look forward to as the new & improved kernels become available. I still have high hopes that the official 2.1 release is going to be a very optimized ROM/kernel for our beloved DROID. And when that kernel gets over-clocked.

UPDATE: I have since removed the CompCache from my DROID. I would get reboots when I tried calling anyone.
