Out of memory while creating bitmaps on device
use this method to resize your bitmap-
Bitmap bm=decodeSampledBitmapFromPath(src, reqWidth, reqHeight);
use this Defination-
public Bitmap decodeSampledBitmapFromPath(String path, int reqWidth,
int reqHeight) {
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);
options.inSampleSize = calculateInSampleSize(options, reqWidth,
reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
Bitmap bmp = BitmapFactory.decodeFile(path, options);
return bmp;
}
}
public int calculateInSampleSize(BitmapFactory.Options options,
int reqWidth, int reqHeight) {
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
if (width > height) {
inSampleSize = Math.round((float) height / (float) reqHeight);
} else {
inSampleSize = Math.round((float) width / (float) reqWidth);
}
}
return inSampleSize;
}
If you are using resource then replace method with BitmapFactory's decodeResource method..
public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId,
int reqWidth, int reqHeight) {
....
.....
return BitmapFactory.decodeResource(res, resId, options);
}
Out of Memory error with Bitmap
OutofMemory occurs when your app exceeds memory allocated in heap. The bitmap is too large to fit in memory ie heap. In such a case you run out of memory. You need to scale down the bitmap and then use the same. For that check the link below
http://developer.android.com/training/displaying-bitmaps/load-bitmap.html.
There is also a blog @ http://android-developers.blogspot.in/2009/01/avoiding-memory-leaks.html (avoiding memory leaks)
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;
}
Quoting from the docs
The BitmapFactory class provides several decoding methods (decodeByteArray(), decodeFile(), decodeResource(), etc.) for creating a Bitmap from various sources. Choose the most appropriate decode method based on your image data source. These methods attempt to allocate memory for the constructed bitmap and therefore can easily result in an OutOfMemory exception. Each type of decode method has additional signatures that let you specify decoding options via the BitmapFactory.Options class.
Setting the inJustDecodeBounds property to true while decoding avoids memory allocation, returning null for the bitmap object but setting outWidth, outHeight and outMimeType. This technique allows you to read the dimensions and type of the image data prior to construction (and memory allocation) of the bitmap.

Out of memory error in android bitmap
You are getting OutOfMemoryError because you haven't recycle
those bitmaps
you used
try to recycle
those bitmaps
after you used them
bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri);
photo_new= rotateImage(bitmap, 90);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
photo_new.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] byteArray = stream.toByteArray();
bitmap.recycle();
Intent i = new Intent(getApplicationContext(),new_class.class);
i.putExtra("image", byteArray);
startActivity(i);
byteArray=null;
out of memory error when using bitmap in recyclerview
Hey you don't have to decode drawable to bitmap.
you can do it like this.
imageview.setImageResource(R.drawable.whatever_the_image_is)
Hope this helps you
