Choose image from gallery and camera through web v

问题:

Here is my code. I am using WebView for registration purposes. In the registration process I have to upload an image from the device. I have finished the code for this and it is working properly in every Android version except Marshmallow. I have given all necessary permissions from the manifest.

The code:

public class WebViewActivity extends Activity {

private static final int INPUT_FILE_REQUEST_CODE = 1;
private static final int FILECHOOSER_RESULTCODE = 1;
private static final String TAG = WebViewActivity.class.getSimpleName();
private static final int TIME_DELAY = 2000;
private static long back_pressed;
private WebView webView;
private WebSettings webSettings;
private ValueCallback<Uri> mUploadMessage;
private Uri mCapturedImageURI = null;
private ValueCallback<Uri[]> mFilePathCallback;
private String mCameraPhotoPath;

@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();
                }
            } catch (Exception e) {
                Toast.makeText(getApplicationContext(), "activity :" + e,

            mUploadMessage.onReceiveValue(result);

The manifest permissions:

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

回答1:

This will allow implementing file uploading in most versions including the marshmellow and its tested too. But doesnt allow uploading multiple files though.

If anyone has a solution for that please do suggest it

The example code on this page helped me achieve these results after searching for hours.

// Create Function for Image Picker

mWebView.setWebChromeClient(new WebChromeClient() {
public boolean onShowFileChooser(
        WebView webView, ValueCallback<Uri[]> filePathCallback,
        WebChromeClient.FileChooserParams fileChooserParams) {

    // Double check that we don't have any existing callbacks
    if(mFilePathCallback != null) {
        mFilePathCallback.onReceiveValue(null);
    }
    mFilePathCallback = filePathCallback;

    // Set up the take picture intent
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    if (takePictureIntent.resolveActivity(getActivity().getPackageManager()) != null) {
        // Create the File where the photo should go
        File photoFile = null;
        try {
            photoFile = createImageFile();
            takePictureIntent.putExtra("PhotoPath", mCameraPhotoPath);
        } catch (IOException ex) {
            // Error occurred while creating the File
            Log.e(TAG, "Unable to create Image File", ex);
        }

        // Continue only if the File was successfully created
        if (photoFile != null) {
            mCameraPhotoPath = "file:" + photoFile.getAbsolutePath();
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                    Uri.fromFile(photoFile));
        } else {
            takePictureIntent = null;
        }
    }

    // Set up the intent to get an existing image
    Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
    contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);
    contentSelectionIntent.setType("image/*");

    // Set up the intents for the Intent chooser
    Intent[] intentArray;
    if(takePictureIntent != null) {
        intentArray = new Intent[]{takePictureIntent};
    } else {
        intentArray = new Intent[0];
    }

    Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
    chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
    chooserIntent.putExtra(Intent.EXTRA_TITLE, "Image Chooser");
    chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);

    startActivityForResult(chooserIntent, INPUT_FILE_REQUEST_CODE);

    return true;
}
});

// Return Data to Web Page

@Override
public void onActivityResult (int requestCode, int resultCode, Intent data) {
    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;
    return;
}
