Android :: Batch Getting Many Bitmap Resources?
Jan 24, 2010
I have a long series of graphics -- icon1_0.png, icon1_1.png, icon1_2.png..., icon12_0.png, icon12_1.png, icon12_2.png -- and I'd like to package them with my android application. Ideally I think I should be able to load them as resources but the resource id's are set up as java identifiers. Of course, java identifiers can't be assembled at runtime. I have to ask for R.drawable.icon12_00 so I cannot set up a loop
for(int icon=0;icon<12;icon++)
for(int frame=0;frame<3;frame++)
//syntax error obviously
BitmapFactory.decodeResource(getResources(), R.drawable."icon" + icon + "_" + frame + ".png");
So is there any way to get resources by their names? Better yet, is there a canonical way outside the resource system to pack data files into an android application package so that I can get at them? I'm thinking about reflection but that doesn't seem like the right solution to me.

I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?

I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:
InputStream is = Resources.getSystem().openRawResource(resourceId)
However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?
Or, is there a way for me in Java to extract all property values from the R.drawable static class?

I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?

My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.

I have G1. I write python scripts using ASE. I have to send around 1000 SMSes using SMS API in ASE. I wonder if G1 will be able to hold up-to that? moreover, how much pause (time gap/ sleep) should I give between each message sent. Some of my colleges think that its a crazy idea. I should go for GSM modem. What do you think, is this feasible enough? Can G1 enough capable? I dont have dev version.

adding new contacts in address book and apply them in batch by using new ContactsContract API. I could not find a proper tutorial on this. I am able to add a single contact. But batch update fails with Unknown contacts being added. Currently I am looping through while loop while collecting info. of users to write, store it in the ArrayList and applying and ContentProviderResult[] result = getContentResolver().applyBatch(ContactsContract.AUTHORITY, op_list); But only one contact is updated with name and other are updated as unknown contacts. Please help with a sample code which adds the fields like name,nickname,mobile,title,email,skype id,work-country etc.

Ever wanted to add words to your user dictionary in batch so you don't need to add them manually one by one?
Now you can!
I just created a project called UserDictionaryUpdater which takes a file called CustomDictionary.txt in your sdcard root and adds all the words from it to your user dictionary.
This is great for people like me who doesn't have language support in Motorola Milestone and don't want to add words one by one.
Please, check it out here:

I'm in the process of planning to switch from a 64GB iPhone 4S to the Samsung Galaxy S3, and one of the things I will miss is the iTunes on-the-fly audio conversion for songs that are 256 kbps to 128 kbps, which allows me to put most of my 100+ GB music collection on the phone at once.
I dont think there are any PC based software that can do the same for Andriod, and even with a potential 96Gb on the phone at once, I don't think my song collection will fit unless I convert them to 128 kbps. So it appears my only solution is to actually convert my song library to 128 kbps (and store seperately) prior to moving them over to my phone.
Any PC based software that can do batch conversions from AAC 256 kbps to 128 kbps while maintainig all the metadata (lyrics, art, genres, etc)? I have over 12,000 songs so it has to be a batch process.

When I'm in the directory tools and try to use "android create avd..." I get an error like "Java is not recognizable as an internal or external command, operable program or batch." What's wrong? I'm using Windows 7 prof Have added android to the system environment variables. (Maybe doesn't change anything.)

Just curious if anyone is worried about getting a phone that is new on the day it is released. Last time I did that I was very disapointed. (VZW Storm 1 owner.) I waited in line to get this PoS and have hated the majority of time I have had it. Anyone worried about something like this with Droid X?

My sprint store has finally recieved the new batch of evos this week. I exchanged mine for one today (had some bad screen light leakage all over the phone and it was slowly growing). immediate thoughts:
Yhe back is noticeably grayer than my old one.
The camera has metal shavings (correct term?) and isnt as "polished" and smoothed as the old one. But it really isnt bad..actually feels rugged and more secure ^^.
Screen colors seem..more realistic?..i believe it is an epson now.
Sensitivity seems just a tad bit better...tested it on my old Evo this morning and it was definately slower.
The bottom and sides seem a bit more sealed than before..although not as much as I'd hope for but i guess i have to give it a week to see if the screen starts separating like last time.
And it is hardware version 3. my old one was 2
So...has anyone else gotten a replacement Evo? and if so, notice anything different?..feedback would be great. oh and I'll get back on the battery and if it's different at all (charging right now).

I'm looking for an app that can batch rename files, none of the file managers I've seen or use seem to be able to do this. It's an operation I repeat many times every day.
It can be achieved as it is with commands in the terminal, but it's quite uncomfortable to do it this way and mostly not worth the effort, also I use Asian characters ( Japanese, Korean ) and things just get too complicated.
Only thing I could find is something called "re.*" but it's not much better than using the terminal.
Is there anything out there that can simply select files, apply a rule, one/two clicks ?

I am in the process of building a new ROM for the Galaxy Note 3. I have great experience with apk's and theming but i decided to take this a step further. I usually take icons from stock AOSP and port into a TouchWiz based ROM and use that as my theme but i want to change this next ROM up. They will be stock icons but with a green color. The name of my ROM is going to be "The Beast" and the green color will greatly add to the experience! Here is my problem though. I have Photoshop CS6 and I tried to change the white parts of the png files to green but it wouldn't happen. It would just turn greyish or just black. So then i was redirected towards Paint.net and i tried it out and it works amazingly except that it doesn't have a batch option or a way to recolor all of my images automatically. I don't have the time or patience to color 500 pngs +. What i need to do to get these icons recolored.

After installing my first ROM I began restoring my apps using titanium backup using batch mode. During the restore, I still had to manually click OK to allow each program to be installed. Is there a way to have it restore everything without having to manually grant each app access? Clicking through 54 apps takes a while.

Lately, it seems that batch restore is broken again on Titanium Backup 4.8. Did a reflash of my friend's phone and using the bath restore function, it wouldn't restore anything and the loading bar would load forever. Restore each app one by one didn't work as well. It was broken in 4.7.X as well for me.
