I try to resize bitmap from gallery.I wrote some code and i can resize bitmap only static width and height.this is source
public Bitmap getResizedBitmap(Bitmap bm, int newWidth) {
float aspectRatio = (float)bm.getWidth() / (float) bm.getHeight();
int height = Math.round(newWidth / aspectRatio); //based on width it gives height
Matrix matrix = new Matrix();
matrix.postScale(newWidth, height);
Bitmap resizedBitmap = Bitmap.createBitmap(
bm, 0, 0, newWidth, height, matrix, false);
return resizedBitmap;
}
but i want to resize bitmap for example width 800px and auto height.is it a possible to solve this problem in android ? thanks

public Bitmap getResizedBitmap(Bitmap bm, int newWidth, int newHeight) {
int width = bm.getWidth();
int height = bm.getHeight();
Bitmap resizedBitmap;
try {
resizedBitmap = Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight());
}catch (Exception e){
e.printStackTrace();
boolean_image = true;
return "";
}
return resizedBitmap;
}

float aspectRatio = (float)Image.getWidth() / (float) Image.getHeight();
int width = 200; //your width
int height = Math.round(width / aspectRatio); //based on width it gives height
