[問題] 拍照沒寫入檔案

[erspicu (.)]

只是一個很簡單的sample

目的只是簡單拍一張照片

部分內容從別的範例改來...

想先簡單抓一張照片輸出jpg檔後再慢慢增加功能

但是不知道為何 雖然執行沒有報錯

但是jpg檔一直沒寫成功

package erspicu.camera;

import android.app.Activity;
import android.os.Bundle;
import android.hardware.Camera;


import java.io.FileOutputStream;
import java.io.IOException;


import android.hardware.Camera.PictureCallback;
import android.hardware.Camera.ShutterCallback;


public class Erspicu_cameraActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        take_picture();
 }


    public void take_picture()
    {


         Camera camera = Camera.open(0);

         Camera.Parameters parameters = camera.getParameters();
         parameters.set("jpeg-quality", 100);
         camera.setParameters(parameters);

         camera.takePicture(shutterCallback, rawCallback, jpegCallback);
         camera.release();
    }

    PictureCallback jpegCallback = new PictureCallback() { // <8>
        public void onPictureTaken(byte[] data, Camera camera) {

          FileOutputStream outStream = null;
          try {

            outStream = new FileOutputStream("/mnt/sdcard/mytest/sample.jpg"); // <9>
            outStream.write(data);
            outStream.close();
          }catch ( IOException e )
          {

          }

        }
      };

    PictureCallback rawCallback = new PictureCallback() {
        public void onPictureTaken(byte[] data, Camera camera) {
        }
      };

    ShutterCallback shutterCallback = new ShutterCallback() { // <6>
        public void onShutter() {
        }
      };

}
