I can capturing, cropping, resizing and saving photos. Saving photos with same resolution (133x171). I need this resolution and greather than 20KB jpeg file size. Sometimes it capture smaller than 20KB. I want to save all photos greather than 20KB. JPEG Quality: 100
StartPreview Codes
public void surfaceCreated(SurfaceHolder holder) {
setWillNotDraw(false);
Log.d("Variable", "surfaceCreated");
try {
mCamera.setPreviewDisplay(holder);
Camera.Parameters parameters = mCamera.getParameters();
if (this.getResources().getConfiguration().orientation != Configuration.ORIENTATION_LANDSCAPE) {
parameters.set("orientation", "portrait");
mCamera.setDisplayOrientation(90);
}
parameters.set("jpeg-quality", 100);
mCamera.setParameters(parameters);
mCamera.startPreview();
} catch (IOException e) {
Log.d("Method.surfaceCreated", "Error setting camera preview: " + e.getMessage());
}
}
PictureTaken method:
@Override
public void onPictureTaken(byte[] data, Camera camera) {
// TODO Auto-generated method stub
/*Bitmap bitmapPicture = BitmapFactory.decodeByteArray(arg0, 0, arg0.length); */
File pictureFile = getOutputMediaFile();
if (pictureFile == null){
Log.d("Method.PictureCall", "Error creating media file, check storage permissions: ");
return;
}
data = cropImage(data);
try {
FileOutputStream fos = new FileOutputStream(pictureFile);
fos.write(data);
fos.close();
Toast.makeText(c, "saved: " + pictureFile.toString(), Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
Log.d("Method.PictureCallBack", "File not found: " + e.getMessage());
} catch (IOException e) {
Log.d("Method.PictureCallBack", "Error accessing file: " + e.getMessage());
}
camera.startPreview();
}
cropImage Method:
public byte[] cropImage (byte[] data) {
Point start_xy = getCaptureStartPoint();
Point cropRes = getCaptureResolution();
int stride = cropRes.x;
int[] pixels = new int[cropRes.x * cropRes.y];
ByteArrayOutputStream bos = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeByteArray(data , 0, data.length);
bitmap = rotateBitmap(bitmap, 90);
bitmap.getPixels(pixels, 0, stride, start_xy.x, start_xy.y, cropRes.x, cropRes.y);
bitmap = Bitmap.createBitmap(pixels, 0, stride, cropRes.x, cropRes.y, Config.ARGB_8888);
bitmap = Bitmap.createScaledBitmap(bitmap, efoto_x, efoto_y, false);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);
return bos.toByteArray();
}
UPDATE #1: Perhaps this isn't best way. But I tried. After write picture file to storage adding some EXIF data to image with this method.
private void addEXIFData(final File f) throws IOException {
ExifInterface exif = new ExifInterface(f.getAbsolutePath());
exif.setAttribute(ExifInterface.TAG_MAKE, "Photo Photo Photo Photo........ bla bla blaaaaa");
exif.setAttribute(ExifInterface.TAG_MODEL, "Photo Photo Photo Photo........ bla bla blaaaaa");
exif.setAttribute(ExifInterface.TAG_ORIENTATION, "90");
exif.setAttribute(ExifInterface.TAG_IMAGE_WIDTH, "150");
exif.saveAttributes();
}
