Ich klicke auf das Bild von Take Picture Button und dann abschicken es auf Senden klicken.

hier ist der gesamte Code

public class MainActivity extends AppCompatActivity { 


private Button image_selector, submit; 
TextView image; 
String encoded_string, image_name = "image 1.jpg"; 
Bitmap bitmap; 
File file; 
String fileUrl = "http://192.168.2.8/image-upload-android/image-upload.php"; 
ImageView image_clicked; 

Uri file_uri; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    image_selector = (Button)findViewById(R.id.image_select); 
    submit = (Button)findViewById(R.id.submit); 
    image = (TextView)findViewById(R.id.image_name); 
    image_clicked = (ImageView)findViewById(R.id.image_clicked); 

    image_selector.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
      getFileUr(); 
      image.setText(image_name); 

      i.putExtra(MediaStore.EXTRA_OUTPUT, file_uri); 
      startActivityForResult(i, 10); 
     } 
    }); 

    submit.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      new Encode_image().execute(); 
     } 
    }); 

} 

private void getFileUr() { 


    file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+ 
    file.separator+ image_name); 
    file_uri = Uri.fromFile(file); 
} 



@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if(requestCode == 10 && resultCode == RESULT_OK){ 

    } 
} 



private class Encode_image extends AsyncTask<Void,Void,Void>{ 
    @Override 
    protected Void doInBackground(Void... voids) { 
     bitmap = BitmapFactory.decodeFile(file_uri.getPath()); 

     ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
     bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream); 

     byte[] array = stream.toByteArray(); 

     encoded_string = Base64.encodeToString(array,0); 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Void aVoid) { 
     makeRequest(); 
    } 
} 

private void makeRequest() { 
    RequestQueue requestQueue = Volley.newRequestQueue(this); 

    StringRequest request = new StringRequest(Request.Method.POST, fileUrl, 
      new Response.Listener<String>() { 
       @Override 
       public void onResponse(String response) { 

        JSONObject jsonObject = new JSONObject(); 
        try { 
         if(jsonObject.names().get(0).equals("success")){ 

          Toast.makeText(MainActivity.this, "Success: "+jsonObject.getString("success"), Toast.LENGTH_SHORT).show(); 

         }else{ 
          Toast.makeText(MainActivity.this, "Error: "+jsonObject.getString("error"), Toast.LENGTH_SHORT).show(); 
         } 
        } catch (JSONException e) { 
         e.printStackTrace(); 
        } 

       } 
      }, new Response.ErrorListener() { 
     @Override 
     public void onErrorResponse(VolleyError error) { 

     } 
    }){ 
     @Override 
     protected Map<String, String> getParams() throws AuthFailureError { 
      HashMap<String, String> map = new HashMap<>(); 
      map.put("encoded_string",encoded_string); 
      map.put("image_name",image_name); 

      return map; 
     } 
    }; 
    requestQueue.add(request);

Verwendung Android Networking. Ich habe diese Bibliothek erstellt, die alle Features enthält, die in Volley fehlen.

AndroidNetworking.upload(url) 
       .addMultipartFile("image", new File(imagePath)) 
       .setTag("uploadTest") 
       .setPriority(Priority.HIGH) 
       .build() 
       .setUploadProgressListener(new UploadProgressListener() { 
        @Override 
        public void onProgress(long bytesUploaded, long totalBytes) { 
        // do anything with progress 
        } 
       }) 
       .getAsJSONObject(new JSONObjectRequestListener() { 
        @Override 
        public void onResponse(JSONObject response) { 
        // do anything with response     
        } 
        @Override 
        public void onError(ANError error) { 
        // handle error 
        } 
       });
