Невозможно сохранить обрезанное изображение - Android

Question

Это мой код получил от here

public class CatFragment extends Fragment implements OnClickListener{ 

     private DBCreater dbCreate; 

     private static final int SELECT_PICTURE = 1; 

     private String selectedImagePath = "android.resource://com.example.abcd/" + R.drawable.pets; 
     private ImageView img; 
     //private Button imgBtn; 

     private Uri mCropImagedUri; 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
       Bundle savedInstanceState) { 
      View gv = inflater.inflate(R.layout.new_pet, null); 

      Spinner sp = (Spinner) gv.findViewById(R.id.ETPetType); 
      // get reference 
      sp.setAdapter(new ArrayAdapter<String>(getActivity().getBaseContext(), android.R.layout.simple_spinner_dropdown_item, petType)); 

      Button btnSubmit = (Button) gv.findViewById(R.id.ButtonNext); 
      btnSubmit.setOnClickListener(this); 

      img = (ImageView)gv.findViewById(R.id.ImageView01); 
     ((Button) gv.findViewById(R.id.ETPetImg)) 
         .setOnClickListener(new OnClickListener() { 
          public void onClick(View arg0) { 
           try { 
            Intent intent = new Intent(); 
            intent.setType("image/*"); 
            intent.setAction(Intent.ACTION_GET_CONTENT); 
            intent.putExtra("crop", "true"); 
            intent.putExtra("aspectX", 0); 
            intent.putExtra("aspectY", 0); 
            intent.putExtra("outputX", 200); 
            intent.putExtra("outputY", 200); 
            intent.putExtra("return-data", false); 

            File f = createNewFile("CROP_"); 
            try { 
             f.createNewFile(); 
            } catch (IOException ex) { 
             Log.e("io", ex.getMessage()); 
            } 

            mCropImagedUri = Uri.fromFile(f); 
            intent.putExtra(MediaStore.EXTRA_OUTPUT, 
              mCropImagedUri); 
            // start the activity - we handle returning in 
            // onActivityResult 
            startActivityForResult(intent, SELECT_PICTURE); 
                  } catch (ActivityNotFoundException anfe) { 
            // display an error message 

           } 
          } 
         }); 

       return gv; 

      } 


      private File createNewFile(String prefix){ 
       if(prefix==null || "".equalsIgnoreCase(prefix)){ 
        prefix="IMG_"; 
       } 
       File newDirectory = new File(Environment.getExternalStorageDirectory()+"/Android/data/com.example.abcd/files/"); 
       if(!newDirectory.exists()){ 
        if(newDirectory.mkdir()){ 
         Log.d(this.getClass().getName(), newDirectory.getAbsolutePath()+" directory created"); 
        } 
       } 
       File file = new File(newDirectory,(prefix+System.currentTimeMillis()+".jpg")); 
       if(file.exists()){ 
        //this wont be executed 
        file.delete(); 
        try { 
         file.createNewFile(); 
        } catch (IOException e) { 
         e.printStackTrace(); 
        } 
       } 

       return file; 
      } 


      public void onActivityResult(int requestCode, int resultCode, Intent data) { 
       if (resultCode == Activity.RESULT_OK) { 
        if (requestCode == SELECT_PICTURE) { 
         Uri selectedImageUri = data.getData(); 
         selectedImagePath = getPath(selectedImageUri); //To get image path 
         System.out.println("Image Path : " + selectedImagePath); 
         img.setImageURI(selectedImageUri); 


        } 
       } 
      } 

public String getPath(Uri uri) { 
     String[] projection = { MediaStore.Images.Media.DATA }; 
     //Cursor cursor = managedQuery(uri, projection, null, null, null); 
     Cursor cursor = getActivity().getContentResolver().query(uri, projection, null, null, null); 
     int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
     cursor.moveToFirst(); 
     return cursor.getString(column_index); 
    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
     //access the database 
     dbCreate = new DBCreater(getActivity()); 

    } 



    @Override 
    public void onClick(View v) { 
     displayNextAlert(); 

    } 

Используя этот код я могу обрезать изображение, но это не спасает и возвращает статистику сообщение Тост Не удалось сохранить обрезанное изображение. Я не вижу других ошибок в LogCat. Пожалуйста, помогите кому-нибудь? Заранее спасибо.

Answer 1

Я получил код для работы путем изменения сохраненного путь к каталогу следующим образом:

File newDirectory = new File(Environment.getExternalStorageDirectory()+"/test/"); 

Причина: Я не мог спасти писать защищенный каталог «/ Android/data/com.example.abcd/files/"

и следующими изменениями к onActivityLes:

public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (resultCode == Activity.RESULT_OK) { 
     if (requestCode == SELECT_PICTURE) { 
     // Uri selectedImageUri = data.getData(); 
     // selectedImagePath = getPath(selectedImageUri); //To get image path 

      selectedImagePath = mCropImagedUri.getPath(); //To get image path 

      System.out.println("Image Path : " + selectedImagePath); 
     // img.setImageURI(selectedImageUri); 


     } 
    } 
} 

ПРИМЕЧАНИЕ. Вам, вероятно, не нужно прокомментировать строку img.setImageURI. Я должен был проверить.
