如何压缩和调整位图大小？

Question

In my application I want crop image from gallery , after cropped convert to base64 and send to server.
Before convert to base64 first convert image to bitmap .
I want after convert to bitmap first compress and resize this bitmap then convert to base64 and sent to server.
I want 10% compressed and set size 1000*1000 to bitmap .

For crop image I use this library : https://github.com/jdamcd/android-crop

My codes:

    private void handleCrop(int resultCode, Intent result) throws IOException {
        if (resultCode == RESULT_OK) {
            if (result != null) {
                Uri imageUri = Crop.getOutput(result);
                Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
                //TODO : Here first compress and resize bitmap
                base64String = ImageConvertBase64.convert(bitmap);
   }
}

before this line i should compress and resize bitmap :

base64String = ImageConvertBase64.convert(bitmap);

How can i it?i am amateur and really need your help, please help me

Use below code for the compress and resize(Set size and compression ration according to your requirement):

Bitmap resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);

resized.compress(Bitmap.CompressFormat.JPEG,90,outStream);
