379,565 | 379,566 | Maximum size of Stream/Bitmap in WallpaperManager | <p>I'm trying to set a resource/stream as Wallpaper in Android. I use the WallpaperManager class and its methods setResource/setStream to do this. I normally scale the images using BitmapFactory.Options before I set them as wallpaper. But this time I wanted to try the full image without any scaling. So I tried to set an image with a resoultion of 5005 x 3274 as wallpaper, without any scaling. And to my surprise, the avd's wallpaper changed to the default stock wallpaper. No exception and no error logs. Below is the code I use. </p>
<p>So is there any limit for the size of wallpaper that can be set? I cannot find any information about maximum image size in WallpaperManager docs. Any help would be appreciated.</p>
<pre><code>public void onBtnClick(View view) {
Thread t = new Thread(new Runnable() {
public void run(){
try{
mgr.setResource(R.drawable.wallpaper);
mHandler.post(new Runnable() {
public void run(){
Toast.makeText(MainActivity.this, R.string.toast_success, Toast.LENGTH_SHORT).show();
}
});
} catch(Exception ioe) {

<p>That's pretty standard. I'm curious to know if there's a way of doing something similar to the code below in Java: (I think I've seen something like it in C)</p>
<pre><code>// The code below doesn't compile (obviously)
while (boolean more = true)
{
// do something
if (someTest())
{
more = false;
}

</code></pre>
<p>I only ask this because currently I don't like the way I'm defining the variable used in the condition (in this case: "more") <em>outside</em> the scope of the loop, even though it's only relevant <em>inside</em> the loop. There's no point it being left hanging around after the loop has finished.</p>

<p>It's not perfect; It's abusing the for loop and I can't think of a way to execute the loop <em>at least once</em>, but it's close... Is there a way to make sure the loop is performed 1+ times?</p>

2,121,364 | 2,121,365 | Covariant return type in Java | <p>The following code uses the concept of method overriding in Java.</p>

}
final class SubClass extends SuperClass

</code></pre>
<p>By convention, method overriding uses the same signature (with return type) in both super class and subclass. In the above code, the return type of the <code>getList()</code> method in the <code>SuperClass</code> is <code>List</code> and in its subclass the return type is <code>ArrayList</code>. How does method overriding work here?</p>
<p>By the way, it's obvious that <code>ArrayList</code> is an implementation of the <code>List</code> interface but how does the compiler treat the return type here while overriding the <code>getList()</code> method?</p>
<p>Should I believe something like this... <em>The return type of the overridden method is allowed to be a subtype of the overridden method's return type.</em></p>

2. scroll the image as it is bigger than screen
3. clicks on the image, get clicked area pixel value(color), so that I know which area the user clicks </p>
<p>I searched many hours, tried many approaches:
1. Write a class that extends View, and display a Bitmap, I found a thread in the forum about it, but there is no zoom, and the scroll is not natural.
2. Use a WebView to display HTML file that contains the image, so there is zoom and scroll functionalities, however, I cannot control the limit of zoom in/out, also, when the user clicks, I'm not sure if I can get the position on the image map by adding scrollX, scrollY with touchX, touchY. As the image may be scaled up/down, also, there may be paddings that WebView adds to its content. </p>
