What is the initial step I need to take?
How does my Java programming experience help in this case?
I'm new to game programming. But I've got an ide for what I think would be a fun game for the Android platform.
My question is, where do I start? Anyone got some good sites to recommend or perhaps a book or two. I've got medium skills when it come to programming but iv got a masters of science degree in computer engineering so I'm not totally unfamiliar with algorithms and stuff.
I am a student and would like to develop softwares for Android Phones. Please suggest me where to start.
I have always programmed in C++, Matlab, Javascript. I do not have so much experience in programming Java.
I have made apps for the iPhone, but want to also code for the Android but want to know if it is first worth my time, second worth my having to learn another language, and third worth the effort in the sense that am I going to make a profit from this. Also if in any way Android code is similar, then will it be hard to bring the iPhone (Xcode) files, or copy and paste my iPhone code into the Android code.

Does anybody know if the new desktop kernel patch written by Mike Galbraith can be applied or modified to be used in the android kernel?

View 1 Replies View RelatedI'm interested in learning Android development but if I install the latest 2.0 SDK, will I still be able to target 1.5 and 1.6 devices? (since there is only one 2.0 device right now)
Basically I'm wondering if it will tell me if I'm doing something that won't work on older versions of the OS.
I'm building an application, and need to support both 1.5 (Magic and Hero) and 1.6 (Tattoo) devices.
As Android SDK is forward compatible, it seemed logical to build against Android 1.5 SDK, and expect application to work on Tattoo. While that's true, (I tested app, it works ok), I'm now having problems on Android Market. On Tattoo, Market search by default filters android apps that doesn't have explicit support for small screens defined in AndroidManifest. Problem is that attribute exists only on Android 1.6 SDK, so Building against Android 1.5 SDK is no an option anymore. How safe is to build App agains A1.6 (with minSdkVersion="3") and run it on 1.5 devices? Is there anything else I should take care of except just change target SDK?
We are upgrading our application to add 2.0 support. I have read http://developer.android.com/guide/appendix/api-levels.html and the older blog post http://android-developers.blogspot.com/2009/04/backward-compatibility.... I want to avoid using reflection if possible. I have found that if I set my minSdkVersion="3" in the application manifest but in my build path in eclipse point to the Adroid 2.0 jar file I can compile with direct calls to 2.0 code (with the relevant code to ensure they are not invoked on <2.0 devices). My question is will people with pre 2.0 devices be able to see the application in the market place in this case? What are other people using for multi-targeting different API levels with the same package.
View 7 Replies View RelatedI'm trying to get rid of the mentioned (READ_PHONE_STATE and WRITE_EXTERNAL_STORAGE) auto-permissions in my signed apk, but I can't. I know it is an issue with targeting 1.5, but this isn't my case. I'm targeting >=1.6. I've checked everything: In my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.aaa.bbb"
android:versionCode="1" android:versionName="1.0.0">
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4" />
Eclipse generates the proper value in default.properties: target=android-4
Last week I published our first app to the Market, which is a game targeted to users in The Netherlands. Now that the G1 has been available over here for a couple of days, we have received feedback from several of our users. When I look at the developers console in the market however, the download count still shows 0.
Also on the device it is listed as <50. When looking around in the Market, I see that all applications targeted to The Netherlands are listed as having <50 downloads, even an application that received a lot of publicity. Have other developers noticed the same?
I am trying to get the intent "android.intent.action.BOOT_COMPLETED" sent only to the receiver "com.android.mms.transaction.MmsSystemEventReceiver" as this triggers the sms notification to be updated and removed if there is no longer any unread sms's. The issue I have is I need to make sure the broadcast is only sent to the class above. If it goes to other receivers the phone could end up in an unknown state or something strange. The code below does not seem to work.
Intent intent = new Intent(); intent.setAction("android.intent.action.BOOT_COMPLETED");
intent.setClassName("com.android.mms", ".transaction.MmsSystemEventReceiver");
activity.sendBroadcast(intent);
This code does work but since it goes to all receivers I have noticed some errors starting to show up in logs etc.
Intent intent = new Intent();
intent.setAction("android.intent.action.BOOT_COMPLETED");
activity.sendBroadcast(intent);
I need to target apps for a specific carrier. Any tips on how to do this? I've seen <uses-library> for market filtering, but looking for something else.
View 3 Replies View RelatedI read here: http://www.androidguys.com/2009/10/11/developers-can-now-target-by-carrier-in-android-market/ that it can be done if you go to the Android Market, and go to your app, then go to Publishing Options -> Locations, but I don't see anything to select a specific carrier there, only specific countries. Is this something that Google changed? Can this still be done, or is it done automatically? Can't the carrier be detected from the device?

I have been seeking beginner learning books in Android, and of course found out that I should learn Java first. So I began studying Java and now I am quite comfortable with objects, classes, inheritance, interfaces, and just moved onto Layouts in Swing as well as Swing Features. But I am starting to wonder.... do I know enough about Java now? Can I start programming Android yet?
Of course I can keep going in Java, but have been itching to begin programming Android apps.
Any definitive answer here about how much Java I need to know before Android?
Basically, I don't know what functions & XML attributes to provide when programming a specific Android feature; eg, Android Search Widget with Edittext in the middle, magnifier glass on the right, and a custom icon on the left.

Which of the following is most suitable for designing simple games? Guessing that the absoluteLayout is easiest, but will it be problems with different screen sizes? What do you recommend?
Will the official 2.1 OTA update include the raise in core clock? Or is this exclusive to the custom 2.1 roms (birdman etc.)
