Camera intent returns small picture

Question

I'm using the camera intent to capture a picture. This is my code and it works great:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); 
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

my onActivityResult looks like this:

if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
    if (resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
        Bitmap photo = (Bitmap) extras.get("data");
    }
}

The problem is, that while the picture taken by the camera is 480*800 (I'm using HTC Desire), the bitmap returned is only 194*324!

Any idea why that happens and how to resolve it?

Thanks!

Solution 1

read this answer to get the full image size How to capture an image and store it with the native Android Camera

---

when you use reading Bitmap from extra, you will get Thumbnail of the image

Solution 2

I have the same problem, I found an example on the google android site: http://developer.android.com/training/camera/photobasics.html

If we want to produce a high quality image from the camera Activity we don’t have a choice but to save it into file and then use:

1. So First of all as before we need to create a static int that will be our requestCode:

public static final int CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE = 1777;

2. Next we fire again the intent to start Activity for result:

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); File file = new File(Environment.getExternalStorageDirectory()+File.separator + "image.jpg"); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file)); startActivityForResult(intent, CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE);

Here we are actually passing an URI as an extra to the intent in order to save the image.

3. Finally we will receive the result in onActivityResult:

           protected void onActivityResult(int requestCode, int resultCode, Intent data) 
            {  
                //Check that request code matches ours:
                if (requestCode == CAPTURE_IMAGE_FULLSIZE_ACTIVITY_REQUEST_CODE) 
                {
                    //Get our saved file into a bitmap object:
   
                   File file = new File(Environment.getExternalStorageDirectory()+File.separator +
            "image.jpg");
                   Bitmap bitmap = decodeSampledBitmapFromFile(file.getAbsolutePath(), 1000, 700);
                }
       }
   

decodeSampledBitmapFromFile method is:

public static Bitmap decodeSampledBitmapFromFile(String path, int reqWidth, int reqHeight) 
{ // BEST QUALITY MATCH

    //First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(path, options);

    // Calculate inSampleSize, Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    options.inPreferredConfig = Bitmap.Config.RGB_565;
    int inSampleSize = 1;

    if (height > reqHeight) 
    {
        inSampleSize = Math.round((float)height / (float)reqHeight);
    }
    int expectedWidth = width / inSampleSize;

    if (expectedWidth > reqWidth) 
    {
        //if(Math.round((float)width / (float)reqWidth) > inSampleSize) // If bigger SampSize..
        inSampleSize = Math.round((float)width / (float)reqWidth);
    }

    options.inSampleSize = inSampleSize;

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;

    return BitmapFactory.decodeFile(path, options);
}

add the relevent camera permissions to the manifest file:

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Hope It would Help anyone how is serching for the solution. As it worked 100% for me.
