“Bitmap too large to be uploaded into a texture”

I am taking a picture using the camera, then I am saving the picture on the sdcard, then using

Bitmap bm = BitmapFactory.decodeFile(path);

To get the bitmap, then

imageView.setImageBitmap(bm); to set it.

But when I put it into my view using

mFrameLayout.addView(imageView); no image is displayed and I get back Bitmap to large to be uploaded into texture

The bitmap is 1944 high, 2592 wide

Any thoughts?

I am using a tablet, 10.1 inches, acer iconia, a500, running ics.

try with this

public static Bitmap decodeFile(File f,int WIDTH,int HIGHT){ try { //Decode image size BitmapFactory.Options o = new BitmapFactory.Options(); o.inJustDecodeBounds = true; BitmapFactory.decodeStream(new FileInputStream(f),null,o); //The new size we want to scale to final int REQUIRED_WIDTH=WIDTH; final int REQUIRED_HIGHT=HIGHT; //Find the correct scale value. It should be the power of 2. int scale=1; while(o.outWidth/scale/2>=REQUIRED_WIDTH && o.outHeight/scale/2>=REQUIRED_HIGHT) scale*=2; //Decode with inSampleSize BitmapFactory.Options o2 = new BitmapFactory.Options(); o2.inSampleSize=scale; return BitmapFactory.decodeStream(new FileInputStream(f), null, o2); } catch (FileNotFoundException e) {} return null; }

this will scale bitmap as per width and height you pass

Why do you divide o.outWidth and o.outHeight by 2? Shouldn't it be just o.outWidth/scale and o.outHeight/scale?

Use this class to scale down your bitmap to a smaller required size before applying it in the image view.

import android.graphics.Bitmap; import android.graphics.BitmapFactory; class BitmapLoader { public static int getScale(int originalWidth,int originalHeight, final int requiredWidth,final int requiredHeight) { //a scale of 1 means the original dimensions //of the image are maintained int scale=1; //calculate scale only if the height or width of //the image exceeds the required value. if((originalWidth>requiredWidth) || (originalHeight>requiredHeight)) { //calculate scale with respect to //the smaller dimension if(originalWidth<originalHeight) scale=Math.round((float)originalWidth/requiredWidth); else scale=Math.round((float)originalHeight/requiredHeight); } return scale; } public static BitmapFactory.Options getOptions(String filePath, int requiredWidth,int requiredHeight) { BitmapFactory.Options options=new BitmapFactory.Options(); //setting inJustDecodeBounds to true //ensures that we are able to measure //the dimensions of the image,without //actually allocating it memory options.inJustDecodeBounds=true; //decode the file for measurement BitmapFactory.decodeFile(filePath,options); //obtain the inSampleSize for loading a //scaled down version of the image. //options.outWidth and options.outHeight //are the measured dimensions of the //original image options.inSampleSize=getScale(options.outWidth, options.outHeight, requiredWidth, requiredHeight); //set inJustDecodeBounds to false again //so that we can now actually allocate the //bitmap some memory options.inJustDecodeBounds=false; return options; } public static Bitmap loadBitmap(String filePath, int requiredWidth,int requiredHeight){ BitmapFactory.Options options= getOptions(filePath, requiredWidth, requiredHeight); return BitmapFactory.decodeFile(filePath,options); } }

Then from your activity, call 

Bitmap reqBitmap = loadBitmap(String filePath,int requiredWidth,int requiredHeight)

method of this class providing the filepath of the bitmap obtained from the sd card, and setting the requiredWidth and requiredHeight to the dimensions you wish to scale the bitmap to. Now use the reqBitmap.
