Might sound crazy, but it's what I need to do. I want to take a Bitmap object and use the XMLPullParser/XmlSerializer to write this to a flat file. Obviously I will need to read the XML tag back into a Bitmap object.So somehow I have to turn my Bitmap into a String and then turn that String back into a Bitmap. I will do some searches on Base64 to see if I get any good examples.
View 2 Replies View RelatedIs there a way to write a bitmap image into an outputstream other than the below method. myView.mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, outputstream); While using the above method there is a loss in quality of the pic for JPEG formats, however for PNG images it is fine.

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.
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've noticed that a lot of comments on top apps are from comment spammers. When is something going to be done about this market wide problem? There are probably less than 20 of these users who hit virtually every top app with comment spam. My app is getting hit every single day by these people. It's really getting annoying.

View 5 Replies View RelatedI am currently using the official Twitter app and it's not too bad on the whole. However, I was wondering if there is a way of being able to comment on photos which have been uploaded via TweetPhoto etc, from the official Twitter app? I know you can add TweetPhoto to your allowed applications via Twitter on a computer, but there doesn't seem to be a way to comment on the photo from my mobile. I could reply to the tweet, but that doesn't leave a comment underneath the picture of TweetPhoto. Hope all that makes sense.

I have read the comments on the market and AppBrain and some people have made reference to retweeting and adding a comment to the retweet.

View 1 Replies View RelatedI just posted a defect / feature request and it was declined without comment. Can anybody explain to me why this was declined without an explanation?
http://code.google.com/p/android/issues/detail?id=2991
I took the time to provide feedback as a user of the android api, based on some discussion in the developer group. I am not the only developer who has encountered this deficiency in the api. I think I explained the deficiency clearly. And I think it is a professional courtesy to provide an explanation. If it is a duplicate, please say so. If I am in error and this is not a problem because of an oversight on my part, I think that would be helpful to know.
If the attitude of the project owners is that the api is good enough. Maybe we could have a short conversation about that.
As it stands now, I have no insight into this issue or why my defect was declined. Was it rejected for good reason or an arrogant developer who like to hit the reject button?

View 1 Replies View RelatedI think it is interesting that you can't say 1 bad thing about this phone or everyone in this forum will either say "bye" or "trade the phone then" or whatever it is. I have the Hero and when people brought up negative things about the phone i agreed with some and disagreed with others. There is no perfect phone out there and when people are shopping for new phones it is good to hear the good and bad then they can make their decision on which one to buy. I would like to see some "real" likes and dislikes on this phone to make an educated decision. Then i can decide if i should pull the trigger on the powerfull EVO wait to possibly get a 2Ghz phone released sometime this year by motorola?

View 4 Replies View RelatedI got my Incredible the week it came out. Last week I started having all sorts of problems and had to reformat the phone several times. Anytime I installed or tried to use an app the phone would crash.They sent me a new one. I put my extended battery in, let it go until it died, then turned the phone off and charged over night. I used the battery, if I remember right, around 60 hours. It definitely got me through 2 full days. This was with my normal use. I don't use it as a phone a whole lot. A call every day or two. Mostly texts, brief internet and some apps. My last phone, the same battery would get me through the day but need recharged over night or I'd be needing to throw it on the following afternoon.So I try my standard battery. Let it drain out, charge it over night, typical use again.It's currently at up time of 33.5 hours and awake time of 1:40:00 with 30% battery left. Again, first phone, that battery would need bumped up a couple of times a day on the charger.Granted when I first got the phone I was obsessed with playing with it, but getting almost 24 hours more between two phones (original and the replacement) using the same battery is odd.It's a hardware 2, just like my last phone. Everything seems to match up spec/number wise in About Phone.I know there are a ton of battery threads, but I didn't know where to put this.

We'd say that's more of an Android thing, though."Quoted directly from engadet's preview."Dont get me wrong: the Droid X is a delight to use. But at times, the hypothetical finish feels a little rougher than it should, and its lacking a certain refinement in how it switches between screens, in how it responds to the touch that one sees in an iPhone or even iPod."Quoted from Zdnet.com's preview.I have hopes that the phone is nice and fluid. I remember the droid when it first came out was lagy, especially on the home screens. Lets hope the X is not.

I'm trying to figure out how to draw on a bitmap in android, and keep a copy of these changed bitmaps for an undo function.
Bitmap b = ...
Paint p = new Paint();
canvas.drawBitmap(b, new Matrix(), null);
canvas.drawCircle(0,0,20,20);
//does Bitmap b have the circle drawn on it next time?
Or how do I get the bitmap after its been drawn on with the canvas(I want to preserve a stack of bitmaps with the changes applied by canvas drawing)? Maybe I'm going about this entirely wrong.
I am trying to grayscale bitmap as follows, But it is crashing as soon as I run this method.
The problem is in last line. How can I assign "int" to "Color"? Or are there any better ways?
