使用httpmime上传多数据 - Android

Question

我按照本教程（http://www.androidhive.info/2014/12/android-uploading-camera-image-video-to-server-with-progress-bar/）上传照片。我在httppost中使用标头身份验证。但是，为什么上传时没有工作。

我使用＆＃39; org.apache.httpcomponents：httpmime：4.3.6＆＃39;在我的依赖中。 任何人都可以帮助我。

这是我的活动。

public class SendReportActivity extends Activity {
private static final String TAG = SendReportActivity.class.getSimpleName();

private String filePath = null;
private ImageView imgPreview;
private ProgressBar progressBar;
private TextView txtPercentage;
private Button btnUpload;
long totalSize = 0;


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

    txtPercentage = (TextView) findViewById(R.id.txtPercentage);
    progressBar = (ProgressBar) findViewById(R.id.progressBar);
    btnUpload = (Button) findViewById(R.id.btnKirim);

    imgPreview = (ImageView) findViewById(R.id.imgPreview);
    Intent i = getIntent();
    filePath = i.getStringExtra("filePath");
    boolean isImage = i.getBooleanExtra("isImage", true);
    if (filePath != null) {
        // Displaying the image or video on the screen
        previewMedia(isImage);
    } else {
        Toast.makeText(getApplicationContext(),
                "Sorry, file path is missing!", Toast.LENGTH_LONG).show();
    }


    btnUpload.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // uploading the file to server
            new UploadFileToServer().execute();
        }
    });
}


private void previewMedia(boolean isImage) {
    // Checking whether captured media is image or video
    if (isImage) {
        imgPreview.setVisibility(View.VISIBLE);
        // bimatp factory
        BitmapFactory.Options options = new BitmapFactory.Options();

        // down sizing image as it throws OutOfMemory Exception for larger
        // images
        options.inSampleSize = 8;

        final Bitmap bitmap = BitmapFactory.decodeFile(filePath, options);

        imgPreview.setImageBitmap(bitmap);
    }
}
