Hello friends if you face bitmap memory out of bound problem then use this method i hope resolve your problem.
First Logic
private void optimizeMemory(String files) throws FileNotFoundException {
Bitmap bitmap;
try {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
FileInputStream fis = new FileInputStream(files);
BitmapFactory.decodeStream(fis, null, options);
fis.close();
final int REQUIRED_SIZE = 270;
int width_tmp = options.outWidth, height_tmp = options.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
BitmapFactory.Options op = new BitmapFactory.Options();
op.inSampleSize = scale;
fis = new FileInputStream(files);
bitmap = BitmapFactory.decodeStream(fis, null, op);
captureFrame(bitmap);
Log.e("FileOp","Optimization "+bitmap.getHeight());
fis.close();
}catch (FileNotFoundException e)
{
e.printStackTrace();
}catch (IOException e)
{
e.printStackTrace();
}
}
Bitmap bitmap;
try {
BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
FileInputStream fis = new FileInputStream(files);
BitmapFactory.decodeStream(fis, null, options);
fis.close();
final int REQUIRED_SIZE = 270;
int width_tmp = options.outWidth, height_tmp = options.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
BitmapFactory.Options op = new BitmapFactory.Options();
op.inSampleSize = scale;
fis = new FileInputStream(files);
bitmap = BitmapFactory.decodeStream(fis, null, op);
captureFrame(bitmap);
Log.e("FileOp","Optimization "+bitmap.getHeight());
fis.close();
}catch (FileNotFoundException e)
{
e.printStackTrace();
}catch (IOException e)
{
e.printStackTrace();
}
}
private void showImage(Bitmap bitmap) {
AlertDialog.Builder myCaptureDialog =
new AlertDialog.Builder(MainActivity.this);
ImageView capturedImageView = new ImageView(MainActivity.this);
capturedImageView.setImageBitmap(bitmap);
ViewGroup.LayoutParams capturedImageViewLayoutParams =
new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
capturedImageView.setLayoutParams(capturedImageViewLayoutParams);
myCaptureDialog.setView(capturedImageView);
myCaptureDialog.show();
}
AlertDialog.Builder myCaptureDialog =
new AlertDialog.Builder(MainActivity.this);
ImageView capturedImageView = new ImageView(MainActivity.this);
capturedImageView.setImageBitmap(bitmap);
ViewGroup.LayoutParams capturedImageViewLayoutParams =
new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
capturedImageView.setLayoutParams(capturedImageViewLayoutParams);
myCaptureDialog.setView(capturedImageView);
myCaptureDialog.show();
}
Second Logic
private Bitmap decodeSampledBitmap(String pathName,int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(pathName, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(pathName, options);
}
//I added this to have a good approximation of the screen size:
private Bitmap decodeSampledBitmap(String pathName) {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
return decodeSampledBitmap(pathName, width, height);
}
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(pathName, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeFile(pathName, options);
}
//I added this to have a good approximation of the screen size:
private Bitmap decodeSampledBitmap(String pathName) {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
return decodeSampledBitmap(pathName, width, height);
}
private int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
I hope resolve your problem.
