What is more expensive to load in a Gallery, a Bitmap or Drawable???
View 1 Replies View RelatedI 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'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.
For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.
Does anyone know how to load images in OpenGL without having a thin outline appear around the images?
I would like to know how to get a pre-saved image from the gallery and then display it onto the screen. Any tutorials/helpful links and info would be appreciated. If there is anything you would like me to explain more, please ask.
View 1 Replies View RelatedIn my application....there are some images like temp1.jpg, temp2.jpg .....upto temp35.jpg,
so on button clicking, i want to load one-by-one image in ImageView ....
i want to do like:
cnt=1; imagename="temp" + cnt + ".jpg"; cnt++;
so my confusion is that "is there anyway to load an image in imageview from string(imagename variable) like temp1.jpg,etc."
I have a query i want to set my ImageView over the Gallery,How to do this? One more thing is there any possibility to display images in android app without using Gallery view.

View 10 Replies View RelatedI have never had any gallery problems that i can remember, but all of a sudden my images/folders arent showing in the gallery. I use a file explorer, and it shows that all my files are there, but for some reason nothing will show in the gallery. sometimes i can gt it to show a "camera" folder and like 3 "download" folders, and some weird folders with numbers and stuff, but they never show thumbnails and wont let you click them.
Gone are my picture folders, and also the galleries from picasa web. I have the droid, with the latest updates and everything. Never had this problem before. Was working the other day. Today i was tryin to send someone a picture, and noticed this.

1: I have noticed that after a couple of days any photos/images I have, be it downloads from a website or photos i've taken with the phone itself disapear from the gallery, but if I hunt for them in the file folder structure they are still on the phone! Similary with...
2: Music, despite me manually dragging some albums over from my laptop, be it in its own folder for the album title or stuffed into one folder called Albums, the music app or Cubed cannot see them, and when I open Cubed it says there are no playlists and dies a death, doesn't give me the opportunity to search for songs on the phone and create one!
Are these issues that have been documented elsewhere? Anyone experience anything similar? Should I be placing my music in one specific folder? the photos should not be disapearing since the phone dictates where they are kept so this one is irritating me!
I am using BitmapFactory.decodeFile to load Bitmaps of images into my application. However, the function returns null on large images (such as those from the camera). The filepath is definitely correct, I just can't figure out why it would return null. I tried supersampling, but it didn't seem to help.
Does anyone have any idea why it would do this or how I could more easily load images taken from the camera into a Bitmap?
Here's the code I am using...
This works great for files.I marked the location needing refactoring to get it to work with a bitmap. I can't seem to find a compatible ContentBody for .addPart.The problem I am trying to solve is that I already have the image in an ImageView within an Activity, so rather than read it again from the SD cara, I want to pass it to this method directly.I will probably scale it while I am at it.
View 1 Replies View RelatedI have a somewhat large (i.e. not fit in most phones' memory) bitmap on disk. I want to draw only parts of it on the screen in a way that isn't scaled (i.e. inSampleSize == 1)
Is there a way to load/draw just the part I want given a Rect specifying the area without loading the entire bitmap content?
Just starting a little game project and have a super basic question. what's the best way to store animation images for a game? I looked at the alien bloodbath code and they store multiple frames in a single png file. Is that the preferred way or is there easier/better way to do it? MP4?

I have a droid raxr maxx with android 4.1.2
Recently I did a bunch of updates and started using google now. My phone performance has been significantly degraded as a result.
My most pressing issue is that after taking a photo, when I go to view it, it shows as normal brightness for 1 second and then gets very dark. This happens for every image as I scroll through them individually. It appears that I now have some sort of editing option or maybe google photos or picassa has hijacked my viewer. When I click on the gallery app this dimming issue does no occur. I am unable to view photos from the camera after taking them.
ContentResolver cr = getContentResolver(); Uri pic = Uri.parse("content://media/external/images/media/3");
Bitmap bm = Media.getBitmap(cr,pic); The above code is written in onCreate method of my Activity class. It throws the following error:
08-30 12:27:22.352: WARN/System.err(245): java.io.FileNotFoundException: No content provider: [content://media/external/images/media/3]
What could be wrong? The file in question is there because I launched Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI) in another method and got back the Uri of the picked image from the returned intent.
I'm developing an image editor for Android. When I do some operations with small pictures (600x600 - 1024x768), the program work well. But when I do some operations with big pictures, I always obtain an OutOfMemory Error. I read read many post trying to have the image in memory. Also I looked at the Android's Gallery, trying to simulate the effect of loading the image with lower quality and get the complete quality after a while. But I doesn't get to work with large images.
I thought of using the parameter inSampleSize but I raised the problem of having to perform operations on the image and save it with the original size, so it no longer serves me. The only thing I've done is use the parameter inJustDecodeBounds and display an error to the user if the image exceeds the available memory.
Is there any possibility of working with large images with no memory problems? I need urgent help.
I need to take a picture with the camera and, if depending on the picture size, rotate it before saving it into the gallery. I'm using
Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(imageCaptureIntent, IMAGE_CAPTURE);
To take the pic and save it to a temporary file. Then
Bitmap bmp = BitmapFactory.decodeFile(imagePath);
String str = android.provider.MediaStore.Images.Media.insertImage(cr, bmp, name, description);
To save it. This is the code i have tried to use to rotate the bitmap.............
I am working on a function to download an image from a web server, redisplay it on the screen, and if the user wishes to keep the image, save it on the SD card in a certain folder. Is there an easy way to take a bitmap and just save it to the SD card in a folder of my choice?My issue is that I can download the image, display it on screen as a Bitmap. The only way I have been able to find to save an image to a particular folder is to use FileOutputStream, but that requires a byte array. I am not sure how to convert (if this is even the right way) from Bitmap to byte array, so I can use a Fileoutput stream to write the data.

View 7 Replies View RelatedI have a html file saved in memory and this file have some images (tag ). I can't load these images because they are in the assets folder and I don't know the absolute path. What is the absolute path to assets folder? I think that with the absolute path of the images I could to load these images in my html file into my webview.
View 1 Replies View RelatedI am trying to save a bitmap in a JPEG format, and i can see that the image is always stored with a lower quality even if i give the compression level as 100, however for PNG it is working fine. Similarly during Media.insert() or getContentResolver().insert() the image is stored with a lesser quality, I can see in that the compression level is 50 in the Media.java, however I tried to create my own method for the same function with quality 100.
View 3 Replies View RelatedI have an Android application that generates some HTML which is rendered locally, in a Webkit view. The details of the HTML generation aren't really that important except for: the bulk of it comes from one place, and I cannot change it the template around that HTML (including headers, footers, HEAD etc), the CSS, and Javascript is under my control. most images are under my control, and rendered separately from the untouchable HTML. These images come from local disk, and do not require the network. It can be assumed that these images are always available. The untouchable HTML contains images which would, ideally be displayed. If the network is unavailable, it is these images that would fail to load. the complete HTML file is likely to be stashed to disk, long before it is rendered. i.e. we cannot render different HTML based on network availability.

I am simply trying to get the path of an image that the user selects and then convert it into a bitmap. The problem is, only some of the images in the gallery work when selected (by "work" I mean they are found to be a file that exists), while the others claim the file does not exist (even though the image is showing up in the gallery?). Even more strange is that this doesn't seem to be consistent, an image that was at one point considered to "exist" now claims to be nonexistent..............
