Камера, снятая камерой, не сохраняется на SD-карте

Question

Я разработал простое приложение для Android в Eclipse для открытия камеры и фотографирования и сохранил его на Sdcard, но когда я запускаю камеру и фотографирую, и когда пытаюсь сохранить мое приложение, что приложение ha остановилось, к сожалению. Я прошу помочь мне, есть ли какие-либо проблемы в моем файле кода вот мой код для сохранения и съемки с камеры.

package cam.cam.pkg; 

import java.io.FileNotFoundException; 
import java.io.IOException; 
import java.io.InputStream; 

import android.app.Activity; 
import android.content.Intent; 
import android.graphics.Bitmap; 
import android.graphics.BitmapFactory; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.ImageView; 

public class CAMActivity extends Activity { 
    private static final int REQUEST_CODE = 1; 
    private Button button_1; 
    public int TAKE_PICTURE = 1; 
    private ImageView image_view; 
    private Bitmap bitmap; 
    /** Called when the activity is first created. */ 
    @Override 
     public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     image_view = (ImageView) findViewById(R.id.result); 
     button_1 = (Button) findViewById(R.id.button1); 

     button_1.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View arg0) { 
       Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); 
       startActivityForResult(intent, TAKE_PICTURE); 
      } 
     }); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     // TODO Auto-generated method stub 
     if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK) 
      try { 
       // We need to recyle unused bitmaps 
       if (bitmap != null) { 
        bitmap.recycle(); 
       } 
       InputStream stream = getContentResolver().openInputStream(
         data.getData()); 
       bitmap = BitmapFactory.decodeStream(stream); 
       stream.close(); 
       image_view.setImageBitmap(bitmap); 
      } catch (FileNotFoundException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     super.onActivityResult(requestCode, resultCode, data); 
    } 
} 

Пожалуйста, Веди меня, что именно мне не хватает в моем коде или любым другим способом, чтобы выйти из этой проблемы

Update

Вот мой Manifest код файла

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="cam.cam.pkg"

Answer 1

попробуйте этот код ::::

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     // TODO Auto-generated method stub 
     if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK) 
      try { 
      image_view.setImageUri(Uri.parse(data.getDataString())); 
      } catch (FileNotFoundException e) { 
       e.printStackTrace(); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
    } 

Обновлено :::: Добавить ниже разрешения п manifeast файл

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

Answer 2

Попробуйте это,

public class Camera extends Activity 
    { 
private static final int CAMERA_REQUEST = 1888; 
private String selectedImagePath; 

@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    Intent cameraIntent = new Intent(ACTION_IMAGE_CAPTURE); 
    startActivityForResult(cameraIntent, CAMERA_REQUEST); 
} 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) 
{ 
    if (resultCode == RESULT_OK) { 
     if (requestCode == CAMERA_REQUEST) 
     { 
      Bitmap photo = (Bitmap) data.getExtras().get("data"); 
      ByteArrayOutputStream bytes = new ByteArrayOutputStream(); 
      photo.compress(Bitmap.CompressFormat.JPEG, 40, bytes); 
      Random randomGenerator = new Random();randomGenerator.nextInt(); 
      String newimagename=randomGenerator.toString()+".jpg"; 
      File f = new File(Environment.getExternalStorageDirectory() 
            + File.separator + newimagename); 
      try { 
       f.createNewFile(); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      //write the bytes in file 

      try { 
       fo = new FileOutputStream(f.getAbsoluteFile()); 
      } catch (FileNotFoundException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      try { 
       fo.write(bytes.toByteArray()); 
      } catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
       uri=f.getAbsolutePath(); 
    //this is the url that where you are saved the image 
     } 



    } 

Answer 3

Попробуйте следующий код. Он работает для меня ...

С помощью метода onActivityResult вызывается следующий код.

Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length); 

    Matrix matrix = new Matrix(); 
    matrix.postRotate(90); 

    int width = bitmap.getWidth(); 
    int height = bitmap.getHeight(); 

    Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true); 

    // Display the captured image oon your screen 
    capturedImageView.setImageBitmap(resizedBitmap); 

    getOutputMediaFileUri(MEDIA_TYPE_IMAGE); 

    File pictureFile = getOutputMediaFile(MEDIA_TYPE_IMAGE); 
    if (pictureFile == null){ 
     Log.d(TAG, "Error creating media file, check storage permissions: "); 
     return; 
    } 

    try { 
     FileOutputStream fos = new FileOutputStream(pictureFile); 
     fos.write(data); 
     fos.close(); 
    } catch (FileNotFoundException e) { 
     Log.d(TAG, "File not found: " + e.getMessage()); 
    } catch (IOException e) { 
     Log.d(TAG, "Error accessing file: " + e.getMessage()); 
    } 

Матричная часть не относится к вашей проблеме напрямую. Тогда вам понадобятся следующие два метода.

private static Uri getOutputMediaFileUri(int type){ 
     return Uri.fromFile(getOutputMediaFile(type)); 
} 

private static File getOutputMediaFile(int type){ 

    File mediaStorageDir = new File(imagesSavingSubfolderPath); 

    if (! mediaStorageDir.exists()){ 
     if (! mediaStorageDir.mkdirs()){ 
      return null; 
     } 
    } 

    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); 

    if (type == MEDIA_TYPE_IMAGE){ 
     mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_"+ timeStamp + ".jpg"); 
    } else { 
     return null; 
    } 

    return mediaFile; 
} 

Будьте осторожны с именем переменной, которое я дал. :-)

В манифесте не забудьте дать следующее разрешение слишком

uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" 

Answer 4

if (requestCode == CAMERA) { 
        Log.d("log", " request code camera " + requestCode); 
        final File file = getTempFile(this); 
        try { 
         selImagePath = file.getAbsolutePath(); 
         m_bmOCRBitmap = Media.getBitmap(getContentResolver(), 
           Uri.fromFile(file)); 
         img_pht.setImageBitmap(m_bmOCRBitmap); 
         hideMenu(); 
        } catch (FileNotFoundException e) { 
         e.printStackTrace(); 
        } catch (IOException e) { 
         e.printStackTrace(); 

        } 
       } 


try this code...
