Android :: Many Image Files In Res / Drawable - Access In Droid?
Feb 11, 2010
I have to make a dedicated image viewer app for Android 2.x.
There are too many jpeg image files: about 2000~ jpegs, over 100MB.
I want access the image files with their file names,
but I couldn't find such an example.
By the way, is it okay to put many image files in /res/drawable folder?
I heard that the android application cannot be installed on sdcard and
the program repository is very small so 100MB app cannot be installed generally.
I found some examples which download the large data files on sdcard online,
but I cannot run a web server to host the data files,
and I must upload the fully packaged program on Android Market. (Should I build one apk file?)
What are the best practices for managing too many resource images (or something) in Android?

I'm using HTC Dream and trying to read the images stored in the "default" album folder of this phone. But I've yet to found out what's the folder path to those images file. do you know what's the path to that image folder? What would be the path patterns (if any) in other Android phones? I don't need to set any additional permission to access those files, do I? Do you know how I can build a "file browsing" widget in my activity? I've searched and seems like there is no such widget and I've to install app that does file browsing. In any case, how to incorporate that as a file-browsing view in my current activity?

On a layout I want to scale the background image (keeping its aspect ratio) to the space allocated when the page gets created. I am using layout.setBackgroundDrawable() and am using a BitmapDrawable to setGravity for clipping and filling, but don't see any option for scaling.

A number of images are "built in" to my app. They are stored in the drawable folder. I'd like to give the option of sending one of these images via mms (or even email) to someone in the user's address book. All the examples I've seen are sending images that are stored somewhere other then the default Eclipse drawable folders.

I have a method in my ItemizedOverlay class which takes an object as a parameter and depending on it's certain values returns an appropriate icon. What's the best way to access the drawable resource from within ItemizedOverlay as you can't access it directly like in an activity? The only idea I have for now is to pass the resources as a second argument...

I've seen references to folks modifying the XML files contained inside the Android.jar.res.drawable folder and then copying them to their drawable folder for use in their project.
But I can't open these files, instead I get the following error.
Could not open the editor: org.eclipse.ui.PartInitException: Editor could not be initialized.
How do I open these files so I can use them?

I have a picture in res/drawable directory: res/drawable/picture.jpeg.
Can I dynamically update this picture.jpeg from code? i.e. I want to use another picture to replace this picture in the drawable directory dynamically. If I can, what path should I use to access the picture? Should I use "res/drawable/picture.jpeg"?

I have an app that I started in 1.6. It used images that were specific to portrait and landscape layouts. I put these in the corresponding drawable folders, for example:
drawable/image01,png
drawable-land/image01.png
when I created a new project with 2.0 it gave me the following folders. drawable drawable-hdpi drawable-mdpi drawable-lpdi. when I look at the documentation around these folders it all seems very straight forward. I assumed that you were able to create the following folders. drawable-hdpi-land drawable-mdpi-land drawable-lpdi-land
and everything would work as before. The image directory would swap automagically pulling the appropriately laid out image depending on your screen orientation. Unfortunately it does not. The SDK seems to get confused, and if I clean the project, the folders come up as poorly named.

I am trying to create a drawable in code and change the color based on some criteria. When I try and set the Drawable as the background of the ImageView it displays but won't let me set any padding. I realized I need to set the ImageView image via the setImageDrawable() function in order to be able to set the padding. The problem I am running into is that when I set it via the setImageDrawable() function nothing is displayed.
Here is what I have written:
<?xml version="1.0" encoding="utf-8"?>
ImageView icon = (ImageView) row.findViewById(R.id.icon);
ShapeDrawable mDrawable; int x = 0; int y = 0;
int width = 50; int height = 50;
float[] outerR = new float[] { 12, 12, 12, 12, 12, 12, 12, 12 };
mDrawable = new ShapeDrawable(new RoundRectShape(outerR, null, null));
mDrawable.setBounds(x, y+height, x + width, y);
switch(position){ case 0: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 1: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 2: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 3: mDrawable.getPaint().setColor(0xff00c000); //Green break;
case 4: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 5: mDrawable.getPaint().setColor(0xff0000ff); //Blue break;
case 6: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 7: mDrawable.getPaint().setColor(0xff696969); //Gray break;
case 8: mDrawable.getPaint().setColor(0xffffff00); //Yellow break;
case 9: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 10: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 11: mDrawable.getPaint().setColor(0xff8b4513); //Brown break;
case 12: mDrawable.getPaint().setColor(0xffa020f0); //Purple break;
case 13: mDrawable.getPaint().setColor(0xffff0000); //Red break;
case 14: mDrawable.getPaint().setColor(0xffffd700); //Gold break;
case 15: mDrawable.getPaint().setColor(0xffff6600); //Orange break;
} icon.setImageDrawable(mDrawable); icon.setPadding(5, 5, 5, 5);
This results in a space for the ImageView but no image.

How can I access the rest of the stuff in the drawable folder, such as the Android emoticons? I can use many of what is in the drawable folder by doing "drawable.XXX" but not all of them are available when I do that.

So I'm defining a class that sets a Drawable attribute in an object. The problem is that I can't access the getResource().getDrawable(int resourceId) method unless I have some Context.
So what I did was to send to that class an activity instance (let's call it "act") and then I did:
act.getResources().getDrawable(R.drawable.whellchair)
but, when executing that line it throws a NullPointerException.
When idea how to accomplish this?

I read about in the google documents that the 3 folders corresponds to different screen types and that android would select the image from different folders automatically according to the screen type. I read that WVGA will load from drawable-hdpi and HVGA will load from drawable-mdpi. When I tested with 2 emulators both running 2.1, each with HVGA and WVGA. It turns out that they are both reading the image in mdpi. If I deleted the image in mdpi then they read from hdpi. Can someone answer why emulator with WVGA is reading from drawable- mdpi?

Im making an app in which the user selects an image and then gets redirected to a new screen in which the drawable name is displayed.
This is the code triggered when the user click an image:
Code:
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Intent tabsIntent = new Intent();
tabsIntent.setClassName("com.budisha.app", "com.budisha.app.TabClassActivity");
tabsIntent.putExtra("pic_name", position); //sends picture position
startActivity(tabsIntent);
}
This sends the new activity the drawable position. But i need to get the drawable name.

I have an image on a private file.
I read the file, create the drawable, and assign it to an ImageView.
The ImageView has WRAP_CONTENT so the size is automatic.
On 320x480 screens, the image looks good
But on screens with more resolution and high density 480x800 or 480x854 (N1, droid) , when the image is for example 150x150, I see the image as 100x100.
Of course it has something to do with the density but not sure how should I resolve this.
This is my code...
if I then inspect the size of the icon, android thinks the size is 100x100, when really is 150x150.
Looks like its reducing the image by the density.
Can anybody explain this and how to avoid this.

I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...
I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?

Can I have sub-folders to hold my drawable resources. For example can I store an image in, say, 'res/drawable/content/images/myimage.jpg' and then find that resource via a call to:
id = context.getResources().getIdentifier("com.mycompany.myprog:drawable/ content/images/myimage", null, null);
I have tried this and it doesn't seem to be working (but I may have something wrong). Is it supposed to work or do all the resources need to be in the root drawable folder? Also, are jpeg files supported and drawable resources?

I have a PNG file that is 32x32 pixels. I use 8 of these as drawables in a row for my app. These drawables are not in the hdpi, mdpi, or ldpi folders. I've found that when starting any of the 3 standard size emulators, the screen view with all 8 drawables looks pretty much the same.
I note that the ldpi emulator I'm using (QVGA) has a resolution of 240x320. 8 x 32 = 256, so since I can see all my drawables (and space in-between) I'm betting something is changing their size.
I've read the Supporting Multiple Screens document at the Android developers page, but I still don't understand what is actually happening. Could you put your own words to explain what is happening to the size of my drawables and how the SDK knows to automatically modify them?

I have a custom drawable, where I draw a base bitmap image, then part of an image over the top of that that is clipped to a certain rectangle. For the overlayed image, I am trying to blur the edges, and I thought I could accomplish that using a BlurMaskFilter, however, I'm not seeing any blurring occurring.
Here is the content of the draw method from my Drawable class.The result is almost correct, except the overlay image is not being blurred.
m_paint = new Paint();
m_blurPaint = new Paint();
m_blurPaint.SetMaskFilter(new BlurMaskFilter(blurRadius, BlurMaskFilter.Blur.Outer));
[code]...
This code is written in C# using Xamarin, so I realize that some things are slightly different, but the overall methods will be the same.
