In your **AndroidManifest.xml** file

    &lt;application
            android:name=&quot;ApplicationClass&quot;
            android:icon=&quot;@drawable/ic_launcher&quot;  &lt;--------
            android:label=&quot;@string/app_name&quot;
            android:theme=&quot;@style/AppTheme&quot; &gt;

***Icon creation wizard***

 - Select your project
 - Ctrl+n
 - Android Icon Set

Look for this on your **Manifest.xml** `android:icon=&quot;@drawable/ic_launcher&quot;` then change the `ic_launcher` to the name of your icon which is on your `@drawable` folder. 

You can find an easy guide [here][1]

The step are 2:
 - Copy the icon in the correct folder/folders
 - Change the AndroidManifest.xml

Rob R.&#39;s answer was definitely the way to go. I tried copying the ic_launcher.png files from another project and Eclipse still wouldn&#39;t read them. Going through the manifest is much quicker and easier.

I have two lists with different objects in them.

    List&lt;Object1&gt; list1;
    List&lt;Object2&gt; list2;

I want to check if element from list1 exists in list2, based on specific attribute (Object1 and Object2 have (among others),  one mutual attribute (with type Long), named attributeSame).

right now, I do it like this:

    boolean found = false;
    for(Object1 object1 : list1){
       for(Object2 object2: list2){
           if(object1.getAttributeSame() == object2.getAttributeSame()){
               found = true;
               //also do something
           }
        }
        if(!found){
            //do something
        }
        found = false;
    }
But I think there is a better and faster way to do this :)
Can someone propose it?

Thanks!

I tried to create buttons and insert my own images instead of the standard button images. However, the gray border from the standard buttons still remains, showing on the outside of my black button images. 

Does anyone know how to remove this gray border from the button, so it&#39;s just the image itself? Thank you.

I am trying to read SharedPreferences inside Fragment. My code is what I use to get preferences in any other Activity.

         SharedPreferences preferences = getSharedPreferences(&quot;pref&quot;, 0);
I get error 

        Cannot make a static reference to the non-static method getSharedPreferences(String, int) from the type ContextWrapper    

I have tried to follow these links but with no luck &lt;https://stackoverflow.com/questions/3806051/accessing-sharedpreferences-through-static-methods&gt; and 
&lt;https://stackoverflow.com/questions/6241340/static-sharedpreferences&gt;. Thank you for any solution.

Android SharedPreferences in Fragment

Which one is better and why?

This one:

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    	super.onActivityResult(requestCode, resultCode, intent);

        ...
    }

or this:

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        // do not call super.onActivityResult()
        ...
    }

Is there a need to use super.onActivityResult() in onActivityResult()?

Every time I try to export an APK from Eclipse (tried Juno and Indigo) on Mac, eclipse crashes after a few seconds

This used to work fine on my current setup.

Running the app straight (debug mode) on my phone works fine.

The error from the console is:

    Invalid memory access of location 0x10073f113 rip=0x101f656f7
    Bus error: 10

I&#39;m using Mac OS X 10.7.4 on a ~2010 MacBook Pro, with the following java:

    java version &quot;1.6.0_33&quot;
    Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-11M3720)
    Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03-424, mixed mode)

I&#39;m using ADT 20.

I&#39;ve tried reinstalling Eclipse and the Android SDK, and re-downloading ADT.

The Eclipse error view doesn&#39;t show anything


Any ideas of different methods I can try, or other ways to investigate what&#39;s going wrong?

Cheers

Update: For anyone coming along post-2014, you should be using &lt;a href=&quot;https://developer.android.com/sdk/installing/studio.html&quot;&gt;Android Studio&lt;/a&gt;, which doesn&#39;t have this problem.

But it shows me a Complete Action View as to select the option (browser/play store). I need to open the application in Play Store directly.

I want to understand this exception in order to implement a proper fix.

There&#39;s a ViewPager and it uses a FragmentStatePagerAdapter to instantiate 2 fragments via getItem and `MyFragmentClass.newInstance(...)`.

Adapter&#39;s getItem looks like this:

    @Override
    public Fragment getItem(int position) {
    	Fragment fragment = null;
    	
    	switch(position) {
	    	case 0:
	    		fragment = MyFragment2.newInstance(par1);
	    		break;
	    	case 1:
	    		fragment = MyFragment2.newInstance(par2, par3);
	    		break;
    	}
    	return fragment;
    }

Problem:

When the activity is destroyed, and created again, the adapter is intantiated again, the fragments created again with `MyFragmentClass.newInstance(...)`... but then on this line:

`pager.setAdapter(adapter);`

I get the mentioned exception.

I looked in the source where the exception is thrown, it&#39;s this:

    @Override
    public Fragment getFragment(Bundle bundle, String key) {
        int index = bundle.getInt(key, -1);
        if (index == -1) {
            return null;
        }
        if (index &gt;= mActive.size()) {
            throw new IllegalStateException(&quot;Fragement no longer exists for key &quot;
                    + key + &quot;: index &quot; + index);
        }
        Fragment f = mActive.get(index);
        if (f == null) {
            throw new IllegalStateException(&quot;Fragement no longer exists for key &quot;
                    + key + &quot;: index &quot; + index);
        }
        return f;
    }

So a bundle is passed there, with some state which references my old fragments, but this doesn&#39;t correspond to the current state (`mActive`), and the exception is thrown.

I don&#39;t understand what&#39;s the idea behind this, or which way I&#39;m supposed to instantiate the fragments.

I tried a trick I got from another context:

`pager.setOffscreenPageLimit(1);`

In order to avoid that the fragments are destroyed when they are off screen (in the case of 2 pages viewpager, although don&#39;t know if it works well with state adapter). But don&#39;t seems to be related, at least, it doesn&#39;t help, still get the same exception.

Catching the exception leads to the pages being blank.

I just tried to send a Maven-based project to another computer and HORROR,
red markers everywhere!!

However, `mvn clean install` is building just fine.

Quickly, I noticed that Lombok is not generating getters and setters for my classes, although the `@Getter` and `@Setter` are being correctly recognised by Eclipse.

Both computers use the same Maven version (3.0.4) but different JDKs (1.6_23 and 1.6_33). They both use Eclipse Indigo 32 bit. Do you have an idea about how to solve the problem?

Lombok is not generating getter and setter

My question is very similar to Stack Overflow question *https://stackoverflow.com/questions/2743647*.

I have tried the solutions presented, but they appear to be old. I have found [a solution][1] that nicely handles the toolbar and menus, but not a solution that reduces the size and padding of the disproportionately large tabs (and label) within the panes (see the tab &quot;Package Explorer&quot; in the screen below).

I am happy with the way my OS-wide GTK theme is customized and don&#39;t want to change that. Is there a quick fix to reduce the tab sizes of the panes in Eclipse?

I&#39;m using Eclipse for Mobile Developers (Juno) on Ubuntu 12.04.  I&#39;ll also mention that I really like the way Eclipse appears out of the box in Windows 7, so something similar to that would be ideal.

Here are the eclipse specific GTK styles I&#39;m using:

    style &quot;eclin&quot; {

For `HDPI`, `XHDPI`, etc. what should be the ideal size of the launcher icon? Should I have to create `9-Patch` images for the icon to scale automatically, or would it be better to create separate icons? 


Android - Launcher Icon Size

As we know, the correct sized icon:

    * drawable-ldpi (120 dpi, Low density screen) - 36px x 36px
    * drawable-mdpi (160 dpi, Medium density screen) - 48px x 48px
    * drawable-hdpi (240 dpi, High density screen) - 72px x 72px
    * drawable-xhdpi (320 dpi, Extra-high density screen) - 96px x 96px

On Jelly Bean, `drawable-xxhdpi` can be supported. So what&#39;s the correct size icon?

    	inflater.inflate(R.menu.options, menu);

How to change option menu icon in the action bar?

![Floating button][1]
The new floating action button should be **56dp x 56dp** and the icon inside it should be **24dp x 24dp**. So the space between icon and button should be **16dp**.

    &lt;ImageButton
        android:id=&quot;@+id/fab_add&quot;
        android:layout_width=&quot;56dp&quot;
        android:layout_height=&quot;56dp&quot;
        android:layout_gravity=&quot;bottom|right&quot;
        android:layout_marginBottom=&quot;16dp&quot;
        android:layout_marginRight=&quot;16dp&quot;
        android:background=&quot;@drawable/ripple_oval&quot;
        android:elevation=&quot;8dp&quot;
        android:src=&quot;@drawable/ic_add_black_48dp&quot; /&gt;

ripple_oval.xml
    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
    
    &lt;ripple xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
        android:color=&quot;?android:colorControlHighlight&quot;&gt;
        &lt;item&gt;
            &lt;shape android:shape=&quot;oval&quot;&gt;
                &lt;solid android:color=&quot;?android:colorAccent&quot; /&gt;

I downloaded collection of icons from [Android Developers center][1]
Each icon in this collection is ordered in forlders according to its resolution: drawable-hdpi, drawable-mdpi, drawable-xhdpi, drawable-xxhdpi.


Is there a way to import all the 4 icon&#39;s files in one action to Android Studio or I need to copy it one by one? 
(when I used new-&gt;Image Asset , I had to fill a file path, I couldn&#39;t fill it with folder path)

**Update 25/2/15:**&lt;br&gt;
According to [this SO question][2], seems like there is a way to generate the 4 size of icons by [Android Asset Studio][3], and then import the zip file directly to your Android Studio project res folder - has anyone used it?

How to import set of icons into Android Studio project

When I create an app with a `flutter create` command, the flutter logo is used as an application icon for both platforms. 

If I want to change the app icon, shall I go to both platforms directories and replace images there?, by platforms directories I mean  `myapp/ios/Runner/Assets.xcassets/AppIcon.appiconset` for iOS and `myapp/android/app/src/main/res` for Android.

Or is it possible to define an image as a [Flutter Asset](https://flutter.io/assets-and-images/) and the icons are generated somehow?.
