android - Android ProgressDialog が AsyncTask と連携しない

Question

別のスレッドで関数を実行しようとしています。残念ながら、それは却下せずに続けています。実行関数内にない場合、Try catch は機能します。関数内にある AsyncTask である可能性があると思いました。

私もこのエラーをキャッチします

java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

これが私のコードです

    btnSubmit.setOnClickListener(new View.OnClickListener() {
    InputStream is = null;

    @Override
    public void onClick(View v) {


        pDialog = ProgressDialog.show(AvvikelseActivity.this, "Registrerar", "Vänta");

        //Start the function here


        //start a new thread to process job
        new Thread(new Runnable() {
            @Override
            public void run() {
                //heavy job here
                //send message to main thread
                try {

                    Bitmap immage = null;
                    //preapare the image
                    immage = BitmapFactory.decodeFile(imgurl);
                    final int maxSize = 960;
                    int outWidth;
                    int outHeight;
                    int inWidth = immage.getWidth();
                    int inHeight = immage.getHeight();
                    if (inWidth > inHeight) {
                        outWidth = maxSize;
                        outHeight = (inHeight * maxSize) / inWidth;
                    } else {
                        outHeight = maxSize;
                        outWidth = (inWidth * maxSize) / inHeight;
                    }
                    Bitmap resizedBitmap = Bitmap.createScaledBitmap(immage, outWidth, outHeight, false);


                    //initiate string imagedata, which will be the string for the actual image

                    //adding the string variables
                    nameValuePairs.add(new BasicNameValuePair("reporter", reporter));

                    //Task to upload the information in background, on another thread
