カメラを使用してファイアベースに画像を保存しても動作しない

Question

カメラで撮影し、その画像（カメラで撮影）をファイアベースのストレージにアップロードしたいと考えています。私はこれに関連する多くの質問を研究しましたが、それは私には意味をなさない。ここに私のコードです。

     Bundle extras = data.getExtras(); 
     imageBitmap = (Bitmap) extras.get("data"); 
     takepic.setImageBitmap(imageBitmap); 
// Actually this uri is null, im confuse in this 

     Uri imageuri= data.getData(); 
     takepic.setImageURI(imageuri); 


     StorageReference filepath= mStorage.child("Saved_Images").child(imageUri.getLastPathSegment()); 
     filepath.putFile(imageuri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() { 
      @Override 
      public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) { 

       String user_id = mAuth.getInstance().getCurrentUser().getUid(); 

       Uri downloadUrl = taskSnapshot.getDownloadUrl(); 
       //DatabaseReference newPost = mDatabase.child(user_id).push(); 
       DatabaseReference newPost = mDatabase.push(); 
       // newPost.child("title").setValue(title_txt); 

       newPost.child("image").setValue(downloadUrl.toString()); 


       Toast.makeText(ActivityCamera.this, "worked ", Toast.LENGTH_SHORT).show(); 
      } 
     }); 
     }} 
} 

私はBASE64にURIを変換する必要がありますが、私はどんな提案または何Iの変化が、私はこのコードで作成する必要がないことを行うことができないということを聞きました。

イメージをキャプチャしてその画像をfirebaseにアップロードする場合は、このコードが役立つことを願っています。その後

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_photo); 
    intent = getIntent(); 
    user = FirebaseAuth.getInstance().getCurrentUser(); 
    getUserToken(); 

    database = FirebaseDatabase.getInstance(); 
    myDBRef = database.getReference("profile"); 
    mStorage = FirebaseStorage.getInstance().getReference().child("profile_photo").child(userUid); 
    mProgressDialog = new ProgressDialog(this); 
    selectedIV = (ImageView)findViewById(R.id.selected_imageView); 
    uploadButton = (Button)findViewById(R.id.upload_button); 
    uploadButton.setVisibility(View.GONE); 
    fromCamera = (Button)findViewById(R.id.from_camera_button); 
    fromCamera.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      try { 
       // use standard intent to capture an image 
       Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

       File direct = new File(Environment.getExternalStorageDirectory() + "/perfectDatingProfile"); 
       if (!direct.exists()) { 
        File wallpaperDirectory = new File(Environment.getExternalStorageDirectory() + "/perfectDatingProfile"); 
        wallpaperDirectory.mkdirs(); 
       } 
       destination = Uri.fromFile(new File(Environment.getExternalStorageDirectory()+"/perfectDatingProfile", "cropped.png")); 
       captureIntent.putExtra(MediaStore.EXTRA_OUTPUT, destination); 

       startActivityForResult(captureIntent, 1); 
      } catch (ActivityNotFoundException anfe) { 
      } 
     } 
    }); 
    laterButton = (Button)findViewById(R.id.later_button); 
    uploadButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      uploadPicture(); 
     } 
    }); 
    myRef = FirebaseDatabase.getInstance().getReference(); 
    selectImageButton = (Button) findViewById(R.id.select_photo_button); 

    laterButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      String userName = intent.getExtras().getString("userName"); 
      String sex = intent.getExtras().getString("sex"); 
      String uid = intent.getExtras().getString("uid"); 
      Integer year = intent.getExtras().getInt("year"); 
      Integer month = intent.getExtras().getInt("month"); 
      Integer dayOfMonth = intent.getExtras().getInt("dayOfMonth"); 
      Double latitude = intent.getExtras().getDouble("latitude"); 
      Double longitude = intent.getExtras().getDouble("longitude"); 
      userObj = new ProfileModel(userName,sex,uid,year,month,dayOfMonth,latitude,longitude,"none", "none"); 
      myRef.child("profile").child(userObj.getUid()).setValue(userObj); 
      startActivity(new Intent(PhotoActivity.this,BaseActivity.class)); 
     } 
    }); 
    if(intent.getExtras() == null){ 
     laterButton.setVisibility(View.GONE); 
    } 
    selectImageButton.setOnClickListener(new View.OnClickListener(){ 
     @Override 
     public void onClick(View v) { 
      Intent cropIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
      cropIntent.putExtra("crop","true"); 
      cropIntent.putExtra("aspectX",1); 
      cropIntent.putExtra("aspectY",1); 
      cropIntent.putExtra("return-data",false); 
      Log.d("------",Environment.getExternalStorageDirectory().toString()); 
      File direct = new File(Environment.getExternalStorageDirectory() + "/perfectDatingProfile"); 
      if (!direct.exists()) { 
       File wallpaperDirectory = new File(Environment.getExternalStorageDirectory() + "/perfectDatingProfile"); 
       wallpaperDirectory.mkdirs(); 
      } 
      destination = Uri.fromFile(new File(Environment.getExternalStorageDirectory()+"/perfectDatingProfile", "cropped.png")); 
      cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, destination); 
      startActivityForResult(cropIntent, 2); 
     } 
    }); 
    ProfileModel sharedModel = getPreferences(); 
    if (sharedModel !=null){ 
     Bitmap bitmap = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory() + "/perfectDatingProfile/profile.jpg"); 
     selectedIV.setImageBitmap(bitmap); 
    } 
} 

あなたのSDカードにあなたの画像を保存することができます。

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == GALLEY_INTENT && resultCode == RESULT_OK){ 
     selectedIV.setImageURI(destination); 
     imageFile = new File(destination.getPath()); 
     uploadButton.setVisibility(View.VISIBLE); 
     toastFilesize(); 
     Bitmap bigProfile = BitmapFactory.decodeFile(destination.getPath()); 
     smallProfile = Bitmap.createScaledBitmap(bigProfile,250,250,false); 
     bitmapToFile(smallProfile,"smallProfile"); 
    }else if (requestCode == 1 && resultCode == RESULT_OK){ 
     selectedIV.setImageURI(destination); 
     imageFile = new File(destination.getPath()); 
     uploadButton.setVisibility(View.VISIBLE); 
     toastFilesize(); 
     Bitmap bigProfile = BitmapFactory.decodeFile(destination.getPath()); 
     smallProfile = Bitmap.createScaledBitmap(bigProfile,250,250,false); 
     bitmapToFile(smallProfile,"smallProfile"); 
    } 
} 

private void toastFilesize(){ 
    Cursor returnCursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, null, null, null); 
    int nameIndex = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME); 
    int sizeIndex = returnCursor.getColumnIndex(OpenableColumns.SIZE); 
    returnCursor.moveToFirst(); 
    Toast.makeText(PhotoActivity.this,Long.toString(returnCursor.getLong(sizeIndex)),Toast.LENGTH_LONG).show(); 
} 
private void bitmapToFile(Bitmap bitmap, String name) { 
    smallImageFile = new File(Environment.getExternalStorageDirectory()+"/perfectDatingProfile", "small.jpg"); 

    OutputStream os; 
    try { 
     os = new FileOutputStream(smallImageFile); 
     bitmap.compress(Bitmap.CompressFormat.JPEG, 100, os); 
     os.flush(); 
     os.close(); 
     Log.d("------",imageFile.getAbsolutePath().toString()); 
    } catch (Exception e) { 
     Log.e(getClass().getSimpleName(), "Error writing bitmap", e); 
    } 
}
