  • Using static variables in Android

    - by michael
    Hi, In android, are using static variables a recommended practice? E.g, implementing a Singleton pattern in Java, I usually do: private static A the_instance; public static A getInstance() { if (the_instance == null) { the_instance = new A(); } return the_instance; } Also, when does this get cleaned up by the Android JVM? Thank you.

  • (Android) How to catch a "ring" event?

    - by rockit
    Hi android developers! I'm clearly a newb, and I was wondering if anyone knows how I can detect a "ring" event on my cellphone through the android sdk? Generally I want to do something with the phone when it begins ringing! Any thoughts? If you want to simply point me to a page in the api documents that would be a good answer for me, I just don't know how to start my research!

  • Dice Emulation - ImageView

    - by Michelle Harris
    I am trying to emulate dice using ImageView. When I click the button, nothing seems to happen. I have hard coded this example to replace the image with imageView4 for debugging purposes (I was making sure the random wasn't fail). Can anyone point out what I am doing wrong? I am new to Java, Eclipse and Android so I'm sure I've probably made more than one mistake. Java: import java.util.Random; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ImageView; import android.widget.Spinner; import android.widget.Toast; public class Yahtzee4Activity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Spinner s = (Spinner) findViewById(R.id.spinner); ArrayAdapter adapter = ArrayAdapter.createFromResource( this, R.array.score_types, android.R.layout.simple_spinner_dropdown_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); s.setAdapter(adapter); } public void onMyButtonClick(View view) { ImageView imageView1 = new ImageView(this); Random rand = new Random(); int rndInt = 4; //rand.nextInt(6) + 1; // n = the number of images, that start at index 1 String imgName = "die" + rndInt; int id = getResources().getIdentifier(imgName, "drawable", getPackageName()); imageView1.setImageResource(id); } } XML for the button: <Button android:id="@+id/button_roll" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/roll" android:onClick="onMyButtonClick" />

  • Android vs iPhone

    - by Moshe
    I know iPhone development fairly well. From personal experience, how hard would it be for me to get into Android. I am concerned less about code than I am about distribution of my software, given the fragmentation of the Android OS on compatible devices.

  • Target a specific Button and Style it

    - by CoffeeAddict
    I've got a button inside my div. The image is showing some kind of padding around it <div id="member-name" hidden="true"> <span><button id="expandButton"><img src="~/Content/Images/plus.jpg" /></button></span><p id="member-fullName"></p> </div> Not sure how to get rid of this issue, see the grey around that plus image..I want to get rid of that. Here's the image alone, see that there is nothing around it: here is my css (just various related snippets to all this): div { padding: 0px;} input[type="submit"], input[type="button"], button { background-color: #ffffff; cursor: pointer; font-size: 11px; font-weight: 600; padding: 0px; margin: 0px; width: auto; vertical-align: middle; } #member-name { margin: 30px 0px 0px 0px; height: 20px; font-weight: bold; color: white; padding: 1px 1px 0px 1px; background-color: #d28105; border: 1px solid darkgray; overflow: hidden; } #member-name.p { display: inline-block; } /* #member-name.input[type="submit"] { margin: 0px;padding: 0px; } - this does not work, probably wrong syntax anyway */

    - by Xiaofeng
    Hi, I made an android application with googlemap api, and draw some 16x16 png (about 200 count) on overlay. When I move or zoom on/in mapview, "out of memory" error occurs very often. I also used the googlemap appication in my htc itself. Seams that it uses about 14+MB memmory, and never happens "out of memory". How to save memmory usage in a googlemap api, or how to enlarge android api memmory limit. Thanks a lot!

  • What's the closest thing to Apple's SpriteKit on Android devices? [on hold]

    - by Krumelur
    I've been playing around with the iOS 7 SpriteKit APIs and I totally love them. As I'm pretty much a n00b on Android, I'm wondering what the best Alternative would be if I wanted to go cross platform? I find Cocos2D learning curve pretty steep, where with SpriteKit it's a matter of minutes to get something on the screen. Then there's MonoGame and Cocos 2D for MonoGame - haven't tried either one I must admit.

  • Android Test testPreconditions

    - by user1184113
    In Android developers I've seen that testPreconditions() method is supposed to be launch before all tests. But in my app test, it's acting like a normal test. It does not run before all tests. Is there something wrong ? Here is the description about testPreconditions() from android developer : "A preconditions test checks the initial application conditions prior to executing other tests. It's similar to setUp(), but with less overhead, since it only runs once."
