android-bitmap

I have a part of code, i use this code four times, but the the sixth time, my application crash , i don't get any Exception or error code. The code is: Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false); I try to use: try{ Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false); }catch (Exception e){ e.printStackTrace(); e.getMessage(); }catch (OutOfMemoryError o){ o.printStackTrace(); o.getMessage(); }catch (AssertionError a){ a.printStackTrace(); a.getMessage(); } catch ( Throwable t ){ t.printStackTrace(); t.getMessage(); } But

I have drawn a square using opengl es 2.0 and now i want to create a bitmap of that drawn square. Can anyone please guide me on how to do that? Please let me know if my question is not clear. Thanks It is done using glReadPixels(). This is slow, but is the only method available with OpenGL ES 2.0 on Android. In Java: Bitmap buttonBitmap = Bitmap.createBitmap(mWidth, mHeight, Bitmap.Config.ARGB_8888); ByteBuffer byteBuffer = ByteBuffer.allocateDirect(mWidth * mHeight * 4); GLES20.glReadPixels(0, 0, mWidth, mHeight, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, byteBuffer); buttonBitmap

I have one main Fragment which is in the background when the second Fragment gets called with getFragmentManager().beginTransaction().add . Right now the user can see the main Fragment behind the second Fragment like it should be. But i want it to be like in a grayed look. When the Second Fragment gets called, the main Fragment should gray out. Im not sure what to google (have tried a lot of keywords) to describe this. My idea was to take a screenshot of the main fragment (bitmap) and make it gray. Is this the right direction? Just put a View in between the Fragments so that it overlays the

I use Picasso (image downloading library for Android). Picasso website I charge my image like this: Picasso.get().load("http://i.imgur.com/myImage.png").into(imageView); But, if myImage.png is too big, the download become slow. (With bad internet connection of course) How to make Picasso load images faster? Can I just make the quality lower by Picasso? Or can I charge them "early" a few seconds before using them? Note that I cannot touch the file myImage.png --------------------- EDIT Any idea how to charge an image "early"? Should I use invisible view and load image into it, then use the same

I am trying to get each frame from a TextureView , unfortunately trying: textureView.getBitmap(); Results in slow performance is there a faster way to obtain a bitmap. Is it better to use the NDK instead? Looking for actual examples A TextureView receives frames on a SurfaceTexture, which takes frames sent to its Surface and converts them to a GLES texture. To get the pixel data out, the texture must be rendered to a framebuffer, then read out with glReadPixels() . The pixel data can then be wrapped with a Bitmap object (which may or may not involve copying the pixel data). Using the NDK isn't

Every time a SurfaceView is redrawn, things that were previously drawn are erased. How do I save their state so that my loop will add new objects to the screen without erasing the old ones? Draw with a Bitmap : Bitmap mDrawBitmap; Canvas mBitmapCanvas; Paint mDrawPaint = new Paint(); @Override public void onDraw(Canvas canvas) { if (mDrawBitmap == null) { mDrawBitmap = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888); mBitmapCanvas = new Canvas(mDrawBitmap); } // draw on the btimapCanvas //... and more mBitmapCanvas.drawWhatever(...); // after drawing with the bitmapcanvas

I am working on an android application. It has a functionality that captured image should display on screen and I need to get that image path, so that I can send that image to server. I am able to display image on screen, but unable to get absolute image path. I am getting path like: content://media/external/images/media/1220 content://media/external/images/media/1221 How can I get actual image path? Here is my code: mintent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); mintent.putExtra(MediaStore.EXTRA_OUTPUT, MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
