Android WebView hochladen Dateiname nicht korrekt Set

Question

ich einfach WebView bin mit Website zu durchsuchen, die Datei Formular mit dem Formularfeld mit dem folgenden Code aus stackovrflow laden hat:

private ValueCallback<Uri> mUploadMessage; 
public ValueCallback<Uri[]> uploadMessage; 
public static final int REQUEST_SELECT_FILE = 100; 
private final static int FILECHOOSER_RESULTCODE = 1; 

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent intent) { 

    Log.i("ME", String.valueOf(requestCode)); 

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
     if (requestCode == REQUEST_SELECT_FILE) { 
      if (uploadMessage == null) 
       return; 
      uploadMessage.onReceiveValue(WebChromeClient.FileChooserParams 
        .parseResult(resultCode, intent)); 
      uploadMessage = null; 
     } 
    } else if (requestCode == FILECHOOSER_RESULTCODE) { 
     if (null == mUploadMessage) 
      return; 
     // Use MainActivity.RESULT_OK if you're implementing WebView inside 
     // Fragment 
     // Use RESULT_OK only if you're implementing WebView inside an 
     // Activity 
     Uri result = intent == null || resultCode != RESULT_OK ? null 
       : intent.getData(); 
     mUploadMessage.onReceiveValue(result); 
     mUploadMessage = null; 
     Log.i("ME", result.toString()); 
    } else 
     Toast.makeText(getActivity().getApplicationContext(), 
       "Failed to Upload Image", Toast.LENGTH_LONG).show(); 
} 



private class MyWebChromeClient extends WebChromeClient { 
    @Override 
    public void onProgressChanged(WebView view, int progress) { 
     // progressDialog.show(); 
     // progressDialog.setProgress(0); 
     // activity.setProgress(progress * 1000); 

     // progressDialog.incrementProgressBy(progress * 1000); 

     progressBar.setProgress(progress); 

     // if (progress == 100 && progressDialog.isShowing()) { 
     // progressDialog.dismiss(); 
     // } 

     // activity.setTitle("Loading..."); 
     // activity.setProgress(progress * 100); // Make the bar disappear 
     // after URL is loaded 
     // Log.i("ME", ""+progress); 

     // Return the app name after finish loading 
     if (progress == 100) { 
      // activity.setTitle(R.string.app_name); 
      loadingUrl = false; 
      progressBar.setProgress(0); 
      progressBar.setVisibility(View.GONE); 
     } 

    } 

    // The undocumented magic method override 
    // Eclipse will swear at you if you try to put @Override here 
    // For Android 3.0+ 
    public void openFileChooser(ValueCallback<Uri> uploadMsg) { 

     mUploadMessage = uploadMsg; 
     Intent i = new Intent(Intent.ACTION_GET_CONTENT); 
     i.addCategory(Intent.CATEGORY_OPENABLE); 
     i.setType("image/*"); 
     startActivityForResult(
       Intent.createChooser(i, "File Chooser"), 
       FILECHOOSER_RESULTCODE); 

    } 

    // For Android 3.0+ 
    public void openFileChooser(ValueCallback uploadMsg, String acceptType) { 
     mUploadMessage = uploadMsg; 
     Intent i = new Intent(Intent.ACTION_GET_CONTENT); 
     i.addCategory(Intent.CATEGORY_OPENABLE); 
     i.setType("*/*"); 
     startActivityForResult(
       Intent.createChooser(i, "File Browser"), 
       FILECHOOSER_RESULTCODE); 
    } 

    // For Android 4.1 
    public void openFileChooser(ValueCallback<Uri> uploadMsg, 
      String acceptType, String capture) { 
     mUploadMessage = uploadMsg; 
     Intent i = new Intent(Intent.ACTION_GET_CONTENT); 
     i.addCategory(Intent.CATEGORY_OPENABLE); 
     i.setType("image/*"); 
     startActivityForResult(
       Intent.createChooser(i, "File Chooser"), 
       FILECHOOSER_RESULTCODE); 

    } 

    // For Lollipop 5.0+ Devices 
    public boolean onShowFileChooser(WebView mWebView, 
      ValueCallback<Uri[]> filePathCallback, 
      WebChromeClient.FileChooserParams fileChooserParams) { 
     if (uploadMessage != null) { 
      uploadMessage.onReceiveValue(null); 
      uploadMessage = null; 
     } 

     uploadMessage = filePathCallback; 

     Intent intent = fileChooserParams.createIntent(); 
     try { 
      startActivityForResult(intent, REQUEST_SELECT_FILE); 
     } catch (ActivityNotFoundException e) { 
      uploadMessage = null; 
      Toast.makeText(getActivity().getApplicationContext(), 
        "Cannot Open File Chooser", Toast.LENGTH_LONG).show(); 
      return false; 
     } 
     return true; 
    } 

} 

Auf Android 5.1 es funktioniert gut. Auf Android 4.xx und senken lädt es die Datei auf den Server normal, aber der Dateiname ist so etwas wie dieses:

image%3A9121 
20098 
24964 

während die eigentlichen Dateinamen so etwas wie sind:

image.jpg 
image.png 
image.jpeg 

Warum ändert die Bilddateinamen zu einer Reihe usw.

die wie dies das Ergebnis Bild-uRL onActivityResult zeigen [mit Log.i ("ME", result.toString());]:

Inhalt: // com .ein droid.providers.media.documents/documents/image% 3A175458

Die Datei ist .jpg, bedeutet das, dass sich das% 3A175458 auf das ".jpg" in irgendeiner Zeichencodierung bezieht ?.

Gelöst mit der Bibliothek aFileChooser.

habe ich nur die Dateien FileUtils.java und LocalStorageProvider.java aus dieser Bibliothek und modifiziert, um die onActivityResult mit diesem Code:

@Override 
public void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 
     if (requestCode != INPUT_FILE_REQUEST_CODE || mFilePathCallback == null) { 
      super.onActivityResult(requestCode, resultCode, data); 
      return; 
     } 
     Uri[] results = null; 
     // Check that the response is a good one 
     if (resultCode == Activity.RESULT_OK) { 
      if (data == null) { 
       // If there is not data, then we may have taken a photo 
       if (mCameraPhotoPath != null) { 
        results = new Uri[] { Uri.parse(mCameraPhotoPath) }; 
       } 
      } else { 
       String dataString = data.getDataString(); 
       if (dataString != null) { 
        results = new Uri[] { Uri.parse(dataString) }; 
       } 
      } 
     } 
     mFilePathCallback.onReceiveValue(results); 
     mFilePathCallback = null; 
    } else if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT) { 
     if (requestCode != FILECHOOSER_RESULTCODE || mUploadMessage == null) { 
      super.onActivityResult(requestCode, resultCode, data); 
      return; 
     } 
     if (requestCode == FILECHOOSER_RESULTCODE) { 
      if (null == this.mUploadMessage) { 
       return; 
      } 
      Uri result = null; 
      try { 
       if (resultCode != RESULT_OK) { 
        result = null; 
       } else { 
        // retrieve from the private variable if the intent is 
        // null 
        result = data == null ? mCapturedImageURI : data.getData(); 

        Log.i("ME", "Uri = " + result.toString()); 
        try { 
         // Get the file path from the URI 
         final String path = FileUtils.getPath(this, result); 
         //Toast.makeText(this, "File Selected: " + path, Toast.LENGTH_LONG).show(); 
         result = Uri.fromFile(new File(path)); 
        } catch (Exception e) { 
         Log.e("Me", "File select error", e); 
        } 

       } 
      } catch (Exception e) { 
       Toast.makeText(getApplicationContext(), "activity :" + e, Toast.LENGTH_LONG).show(); 
      } 
      mUploadMessage.onReceiveValue(result); 
      mUploadMessage = null; 
     } 
    } 
    return; 
}
