无法上传图像android

-1

我正在一个应用程序中，我想从图库或相机中获取图像，然后使用multipart将其发送到服务器。我能够从画廊发送图片到服务器，但是当我试图从相机发送图像时，它显示我失败。对于同一无法上传图像android

//代码来回开相机

 private void cameraIntent() { 
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
    startActivityForResult(intent, REQUEST_CAMERA); 

}

//对活动结果

//代码

public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
     if (requestCode == REQUEST_CAMERA) { 
      Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); 
      ByteArrayOutputStream bytes = new ByteArrayOutputStream(); 
      thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes); 
      File destination = new File(Environment.getExternalStorageDirectory(), 
        System.currentTimeMillis() + ".jpg"); 

      Log.d("TAG", "onActivityResult: "+Uri.fromFile(destination));

请问您可以在这里添加错误日志 – UltimateDevil

使用断点将有助于您更好地确定问题。 –

请走槽下面的代码

试试这个，它可以帮助

Intent takePhotoIntent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
Date date = new Date(); 
     String timeStamp = new SimpleDateFormat(pictureNameDateFormat, Locale.US).format(date.getTime()); 
    File fileDirectory = new File(Environment.getExternalStorageDirectory() + "/Pictures"); 


if (fileDirectory.exists()) { 
       takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(
         new File(Environment.getExternalStorageDirectory() + "/Pictures/picture_"+ timeStamp + ".png"))); 
       takePhotoIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); 
       takePhotoIntent.setFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION); 
       if (takePhotoIntent.resolveActivity(activity.getPackageManager()) != null) { 
        activity.startActivityForResult(takeVideoIntent, captureVideoActivityRequestCode); 
       } 
      }

请使用下面的代码通过摄像头和从图库中选择图像，以撷取图片，你还可以裁剪。

首先，请确保您的build.gradle

compile 'com.theartofdev.edmodo:android-image-cropper:2.3.+'

添加这种依赖在你的活动请添加以下代码：

uploadPic.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) {    
       onSelectImageClick(view); 
      } 
     }); 

/** 
    * Start pick image activity with chooser. 
    */ 
    public void onSelectImageClick(View view) { 
     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 

      if (ContextCompat.checkSelfPermission(AccountSettingActivity.this, android.Manifest.permission.CAMERA) + ContextCompat.checkSelfPermission(AccountSettingActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) { 
       ActivityCompat.requestPermissions(AccountSettingActivity.this, new String[]{android.Manifest.permission.CAMERA, Manifest.permission.READ_EXTERNAL_STORAGE}, MY_REQUEST_CAMERA); 
      } else if (ContextCompat.checkSelfPermission(AccountSettingActivity.this, android.Manifest.permission.CAMERA) + ContextCompat.checkSelfPermission(AccountSettingActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) { 
       CropImage.startPickImageActivity(this); 
      } 
     }else { 
      CropImage.startPickImageActivity(this); 
     } 
    } 

@Override 
    @SuppressLint("NewApi") 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

     // handle result of pick image chooser 
     if (requestCode == CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE && resultCode == Activity.RESULT_OK) { 
      Uri imageUri = CropImage.getPickImageResultUri(this, data); 
      startCropImageActivity(imageUri); 
     } 

     // handle result of CropImageActivity 
     if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) { 
      CropImage.ActivityResult result = CropImage.getActivityResult(data); 
      if (resultCode == RESULT_OK) { 
       fileUri = result.getUri(); 
       userImage.setImageURI(result.getUri()); 
       Toast.makeText(this, "Cropping successful, Sample: " + result.getSampleSize(), Toast.LENGTH_LONG).show(); 
      } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) { 
       Toast.makeText(this, "Cropping failed: " + result.getError(), Toast.LENGTH_LONG).show(); 
      } 
     } 
    } 

    @Override 
    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { 
     if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) { 
      CropImage.startPickImageActivity(this); 
     } else { 
      Toast.makeText(this, "Cancelling, required permissions are not granted", Toast.LENGTH_LONG).show(); 
     } 
    } 

    /** 
    * Start crop image activity for the given image. 
    */ 
    private void startCropImageActivity(Uri imageUri) { 
     CropImage.activity(imageUri) 
       .setGuidelines(CropImageView.Guidelines.ON) 
       .setMultiTouchEnabled(true) 
       .start(this);

她没有要求任何图书馆的人。 – UltimateDevil

给一试！

private static final int REQUEST_IMAGE = 100; 
private static final String TAG = "MainActivity"; 
TextView imgPath; 
ImageView picture; 
File destination; 
String imagePath; 

//onCreate 

    private void cameraIntent() { 
     Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(destination)); 
     startActivityForResult(intent, REQUEST_IMAGE); 
    } 

} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if(requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK){ 
     try { 
      FileInputStream in = new FileInputStream(destination); 
      BitmapFactory.Options options = new BitmapFactory.Options(); 
      options.inSampleSize = 10; 
      imagePath = destination.getAbsolutePath();//get your path 
      imgPath.setText(imagePath); 
      Bitmap bmp = BitmapFactory.decodeStream(in, null, options); 
      picture.setImageBitmap(bmp); 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } 

    } 
    else{ 
     imgPath.setText("Request cancelled"); 
    } 
}

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

在清单请加上这些权限，并要求运行时的权限也，这可能会解决你的问题，你的编码是正确的那些作品，我同意加入后完全。
