• Why Android for new (micro) consoles?

  - by Klaim

  There are a lot of new (micro) consoles with Android inside coming soon or already there (OUYA for example). My question is: why use Android and not another OS as base for these consoles? I assume that there are pragmatic answers to this but I can't see any clear killer feature. For example, one can assume that any stable Linux distribution would work (like Valve seem to think). Android is primarily targetted at mobile platforms which mean it is built around the idea of being interrupted which goes against a lot of what console devs needs in new hardware - but is not killing Android as a platform for gamedev either as it's just a constraint. Why not another OS? What's the Android killer features that make micro-console builder using it instead of Linux or anything else?

• Android “open for embedded”? Must-read Ars Technica article

  - by terrencebarr

  A few days ago ars technica published an article “Google’s iron grip on Android: Controlling open source by any means necessary”. If you are considering Android for embedded this article is a must-read to understand the severe ramifications of Google’s tight (and tightening) control on the Android technology and ecosystem. Some quotes from the ars technica article: “Android is open – except for all the good parts“ “Android actually falls into two categories: the open parts from the Android Open Source Project (AOSP) … and the closed source parts, which are all the Google-branded apps” “Android open source apps … turn into abandonware by moving all continuing development to a closed source model.” “Joining the OHA requires a company to sign its life away and promise to not build a device that runs a competing Android fork.” “Google Play Services is a closed source app owned by Google … to turn the “Android App Ecosystem” into the “Google Play Ecosystem” “You’re allowed to contribute to Android and allowed to use it for little hobbies, but in nearly every area, the deck is stacked against anyone trying to use Android without Google’s blessing“ Compare this with a recent Wired article “Oracle Makes Java More Relevant Than Ever”: “Oracle has actually opened up Java even more — getting rid of some of the closed-door machinations that used to be part of the Java standards-making process. Java has been raked over the coals for security problems over the past few years, but Oracle has kept regular updates coming. And it’s working on a major upgrade to Java, due early next year.” Cheers, – Terrence Filed under: Embedded, Mobile & Embedded Tagged: Android, embedded, Java Embedded, Open Source

• Java ME SDK 3.0.5 Integrated with NetBeans 7.1.1

  - by SungmoonCho

  NetBeans 7.1.1 now integrates Java ME SDK 3.0.5, so you do not have to download them separately. Java ME SDK was packaged in NetBeans Mobility Pack, a mobile application development toolkit for NetBeans. Therefore, Java ME SDK is no longer a separate menu on NetBeans. For those who have not downloaded Java ME SDK yet, please simply visit NetBeans website and download the latest version. For those who already have Java ME SDK integrated with NetBeans 7.1 or earlier, and want to update NetBeans IDE to 7.1.1, don't worry. They can co-exist. To use NetBeans plug-ins such as Device Selector, profiler, and Internationalization Resource Manager, you have to install "Java ME SDK Tools" from NetBeans. Here is how. 1.  Go to "Tools - Plug-ins" from NetBeans menu. You can find all the plug-ins you can install into NetBeans. Locate "Java ME SDK Tools" from the list. 2. Follow the instruction to install Java ME SDK Plug-ins. 3. Once completed, you will see new menu options. For example, you can find Device Selector under Tools - Java ME. (If you used old version of Java ME, you will notice that there is not 'Java ME' menu any more. This is because all the sub-menus were integrated into appropriate places in NetBeans.) There is one thing to keep in mind; Since NetBeans 7.1.1 already includes Java ME SDK 3.0.5 and Java ME SDK 3.0.5 plug-ins must be installed through NetBeans plug-in menu, you should not download Java ME SDK 3.0.5 separately and try to integrate it with NetBeans. This may cause issues.

• Opening email attachments in Android

  - by zehrer

  I try to open a specific email attachment type with my activity, the attachment itself is a plain text windows style ini file with the extension *.os. In the email this file is attached as "application/octet-stream". I tried the following intent-filter to catch the attachment with my activity: <intent-filter> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.DEFAULT"/> <category android:name="android.intent.category.BROWSABLE"/> <data android:scheme="http" android:host="*" android:pathPattern=".*\\.os"/> <data android:scheme="https" android:host="*" android:pathPattern=".*\\.os"/> <data android:scheme="content" android:host="*" android:pathPattern=".*\\.os"/> <data android:scheme="file" android:host="*" android:pathPattern=".*\\.os"/> </intent-filter> The Email app is fetching the attachment but is then telling me "The attachment cannot be displayed". What can I do? How can I debug this?

• Using android.view.SurfaceView with a camera on part of the screen

  - by oneself

  Hi, I trying to put together an Android app that will take a picture and process it in some way. I'd like the layout to be similar to Google Goggles. Meaning, camera preview on the top, and some controls on the bottom using portrait orientation. I've built a first version using code sample from here. This works, but I want to add a button on the bottom. I've modified my main.xml to look as follows: <?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="150dp" android:stretchColumns="1"> <TableRow> <android.view.SurfaceView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/preview" android:layout_width="fill_parent" android:layout_height="fill_parent" /> </TableRow> <Button android:id="@+id/snap" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Snap" /> <TableRow> </TableRow> </TableLayout> But when I run this code I get an exception: java.lang.RuntimeException: startPreview failed. When I replace the SurfaceView above with something else, e.g. a TextView, that it displays, but in landscape. How can I get a camera preview on part of the screen using portrait view? Thanks

• Android: SharedPreference: Defaults not set at startup...

  - by Allan

  I have Listpreferences in my app. They don't appear to be setting to their defaults right after installation - they appear to be null. I'm trying to figure out why my default preferences are not being set right after installation. In my main code I have: SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this); InUnits = sp.getString("List1", "defValue"); InAngs = sp.getString("List2", "defValue"); OutUnits = sp.getString("List3", "defValue"); OutAngs = sp.getString("List4", "defValue"); Right after the above code executes, each variable contains "defValue" instead of the actual values I have assigned in my ListPreference below. My preference xml file is called, "settings.xml". Here's what one of the ListPreferences there looks like: <ListPreference android:key="List1" android:title="Input: Alph" android:summary="Choose Alph or Ralph" android:entries="@array/inputAlph" android:entryValues="@array/input_Alph_codes" android:dialogTitle="Input Alph" android:defaultValue="ININ"/> Here's what some of my strings.xml file looks like: <string-array name="inputUnits"> <item>Alph</item> <item>Ralph</item> </string-array> <string-array name="input_Alph_codes"> <item>ININ</item> <item>INMM</item> </string-array> When I go to menu, and then settings, I can see my defaults checked (radiobuttoned). Then when I go back from the settings menu to my main screen - all is well - for life! ...then each var above is assigned the proper default value. This only happens when I first install my app on the phone. After I go to the settings screen once and then right out of it, the app is fine and accepts any setting changes. By the way, as you can see, "List1" is the android:key within a file called settings.xml in my res/xml folder.

• NotFoundException in layout editor for Android?

  - by borg17of20

  I'm trying to extend a RelativeLayout object and include an embedded SurfaceView object that uses a png file in my /res/drawable folder as its background but I keep getting an error in the XML Layout editor. See the following code: public class StopMotionRelativeLayout extends RelativeLayout { private Context myContext; private SurfaceView surfaceView1; private BitmapFactory.Options myBitmapOptions; private final android.view.ViewGroup.LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.FILL_PARENT); public StopMotionRelativeLayout(Context context, AttributeSet attrs) { super(context, attrs); myContext = context; this.setBackgroundColor(Color.GREEN); //init images surfaceView1 = new SurfaceView(myContext,attrs); surfaceView1.setVisibility(View.INVISIBLE); this.addView(surfaceView1, params); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); myBitmapOptions = new Options(); myBitmapOptions.outWidth = widthMeasureSpec; myBitmapOptions.outHeight = heightMeasureSpec; surfaceView1.setBackgroundDrawable(new BitmapDrawable(BitmapFactory.decodeResource(this.myContext.getResources(), R.drawable.golf1, myBitmapOptions))); } } I get the following error: NotFoundException: Could not find drawable resource matching value 0x7F020002 (resolved name: golf1) in current configuration. I have seen this type of error may times now and it always happens when I try to load something from a resource file via code and not XML. Curiously, this error does not stop me from compiling the app, and the app runs without error in the emulator. I'd like to get back the use of my layout editor though... Please help. UPDATE: Here is the layout XML <?xml version="1.0" encoding="utf-8"?> <com.games.test.StopMotionRelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> </com.games.test.StopMotionRelativeLayout>

• Android - BroadcastReceiver CONNECTIVITY ACTION

  - by Marc Ortiz

  in my project there's a service that listens for changes in the connectivity. When wifi is switched off to on then it gets called. The problem it's that i'm using a fragment and inside a fragment there's a button with the setonclicklistener(); and onclick(); SOMETIMES when i touch the button then the service receives an intent that the connectivity has changed (the method gets called without any reason...). Here's the code of my fragment activity for the viewpager layout: public static class FragmentSelection extends Fragment { int mNum; static FragmentSelection newInstance(int num) { FragmentSelection f = new FragmentSelection(); // Supply num input as an argument. Bundle args = new Bundle(); args.putInt("num", num); f.setArguments(args); return f; } /** * When creating, retrieve this instance's number from its arguments. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mNum = (getArguments() != null ? getArguments().getInt("num") : 1) + 1; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { final View v = inflater.inflate(R.layout.fragment_intro_contenido, container, false); Button btStart = (Button) v.findViewById(R.id.btChanged); final

• Issue with Running Android Program on Eclipse

  - by Hossein Mobasher

  I downloaded complete Android Environment Development Environment Snapshots from marakana.com. I start eclipse and create new Android project. On the Run Configurations, i created New Configuration to run the application, and set the Target to Automatic and select the AVD that appropriate to run the application. But, when i click on the run icon, it starts the new emulator, and after some minutes, just android emulator be ran and my application doesn't run on it. What do i do to solve the running problem and run my project on emulator ?

• android costumized button problem with changing text color

  - by alaxid

  Hi, I made a button that changes the background drawable on different states, this way: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:drawable="@drawable/btn_location_pressed" /> <!-- pressed --> <item android:state_focused="true" android:drawable="@drawable/btn_location_pressed"/> <!-- focused --> <item android:drawable="@drawable/btn_location"/> <!-- default --> The problem here is that I'm also trying to change the textColor as I do with the drawable but I'm not being able to. I already tried android:textColor and android:color but the first doesn't work whilst the seconds changes my background. The next code is part of my layout. Regarding to the text color it only works for the normal state text color, thus not changing it to the white one while pressed <Button android:id="@+id/location_name" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingTop="5dp" android:background="@drawable/location" android:textSize="15sp" android:textColor="@color/location_color" android:textColorHighlight="#FFFFFF" /> As anybody got a clue? ty! :)

• Validating a phone number in Android PreferenceScreen

  - by djechelon

  I have a PreferenceScreen in which the user is capable, if system can't autodetect it, to enter the device's phone number. I'm still learning this part of Android but I managed to understand a bit of PreferenceScreens by examples provided by Android SDK itself and a few tutorials. What I want is that the user can save the phone number only if null or valid, where by "valid" I mean running a generic validation logic (ie. an anonymous method that returns true or false, that can be reused in any possible situation*) or better, just to simplify things, ^(\+39)?3[0-9]{9}$ For now I have the following XML snip <EditTextPreference android:inputType="phone" android:key="@string/preference_phoneNo" android:selectAllOnFocus="true" android:singleLine="true" android:summary="@string/pref_phoneNumber_description" android:title="@string/pref_phoneNumber" /> and following code by courtesy of Eclipse New Activity wizard: private void setupSimplePreferencesScreen() { if (!isSimplePreferences(this)) { return; } addPreferencesFromResource(R.xml.pref_general); bindPreferenceSummaryToValue(findPreference(getString(R.string.preference_phoneNo))); } addPreferenceFromResource is supposed to load the XML node and add the preference to the screen, while binPreferenceSummaryToValue is supposed to make description text change when preference is updated. Just for sake of completeness for those who don't like code courtesy of the IDE, the second method is provided by Eclipse who also provides a private class in the code file that is /** * A preference value change listener that updates the preference's summary * to reflect its new value. */ In the general case, what should I do to perform validation logic before the preference gets saved when I click OK on the preference editor? Where is the validation logic to be put in a PreferenceScreen? *Aren't we all here to learn?

• changes in main.xml are not reflected in the android app in netbeans

  - by nitish712

  I am new to android apps. I am using the netbeans 7.0.1 IDE to develop android apps. I have written the following code in the main java file: package com.test.helloworld; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class helloworld extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TextView t1=new TextView(this); t1.setText("hello world..!!!!"); setContentView(t1); } } This was working fine. I edited the main.xml file to display a textfield and button as follows: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send"/> <EditText android:id="@+id/edit_message" android:layout_width="wrap_content" android:layout_height="wrap_content" android:hint="@string/edit_message"/> </LinearLayout> Of course I have added all the corresponding strings in strings.xml. But when I try to run my app these weren't displaying... :( . I mean the same string that was displayed previously was being displayed. Can anybody figure out what is the mistake? thanx...

• Is there an easy way to setup the android emulator to access the LAN of the host machine ?

  - by Longfield

  I would like to access a web service provided by one of the machines on my LAN from the android emulator. If the service was running on the same machine where the emulator is running (called host), I could add a network redirection and access the 10.0.2.2 (host loopback interface in the emulator) with the correct port. However it is running on another machine on the LAN. I guess I could add another redirection on the host additionally to the above one (would have to fight with iptables though ... ), but does a more simple solution exist ?

• Android/Java Javadoc missing after updating Android SDK

  - by binnyb

  After i recently installed the new Android SDK stuff, I no longer can view the Javadoc while editing my project's code. I get this message: Note: This element has no attached source and the Javadoc could not be found in the attached Javadoc. I am getting this message for all methods, variables, classes, etc. I have installed the documentation and everything available to me via the android update manager. I have also tried to do a clean install of the android sdk and eclipse, and no luck getting the javadoc working. I have also tried manually setting the javadoc via project properties -> javadoc location -> file:/C:/Program Files/Android/android-sdk-windows/docs/reference/ with no luck What suggestions do you have that could fix this problem?

• N64oid Brings N64 Emulation to Android Devices

  - by ETC

  Craving some Ocarina of Time adventures, Super Mario 64 antics, or some Star Fox 64 flying on your Android device? N64oid brings retro emulation of Nintendo’s popular N64 console to Android devices. N64oid is an N64 console emulator for Android devices. You’ll need a copy of the $5.99 emulator, ROMs (from the usual sources, unless you’ve got a ROM ripping setup in your basement and a stack of old cartridges), and a suitably speedy Android device. Older Android devices will find the playback choppy and subpar, but newer and speedier devices like the Nexus-One and Samsung Galaxy should have no problem handling the emulator. Like all emulators N64oid is a work in progress and emulating an entire closed-system console on a totally different set of hardware is never a perfect 1:1 emulation, but if you’re a die hard fan of classic N64 titles (check out this list of top ranked titles to inspire some nostalgia) N64oid is worth the price of a burger for sure.

• Why does Android make good coding so difficult?

  - by metacircle

  my daily work is writing tools in C#/WPF. After over more than 1 year on the job now, I came to love MVVM, IoC Containers, XAML (and more). It's pure fun to write code, since simple, maintainable and extendable code just comes naturally when you follow a few basic patterns. In my free time I really want to write some apps, mainly for my own personal use. I want to write apps for fun and not to make money or anything, that being said, paying an annual fee to be allowed to use my own apps on my own device is a total no-go for me. So I am not able to code for Windows Phone and am also not able to use Xamarin on Android (which is sad since Visual Studio + Resharper is programmers heaven). So I am stuck with Android "classic" Java development. Everytime I sit down at home to create an app, or improve some of the code I have already written I get annoyed very quick because getting good, decoupled code is just so hard to accomplish. It feels like everything you have to do in Android to create a good architecture is a workaround instead of being the way things are meant to be. Writing the UI in xml is fine, but everything else is one big code mess. Even all the tutorials do all their coding in the code behind. For 'hello world' this is fine, but for anything bigger this gets messy very very quick. This is where the fun for me ends. It's just no fun anymore because I just spend 90% of my time refactoring and thinking of workarounds how to make my code more maintainable with all the restrictions Android puts on me. Am I missing a crucial part or is this just the way Android is meant to be? Do you have any suggestions how to learn 'the fun way' of Android programming.
