View intent on Android

[armandn]

I managed to register my app as the default handler for a file type (mime type) and I think the plugin could be modified/extended to do this as well.

Note that in my tests I did not register a separate activity, I used MainActivity. it seems to work fine, although I'll have to do more tests.

In AndroidManifest.xml:

<intent-filter>
    <action android:name="android.intent.action.SEND" />
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="[MY MIME TYPE]" />
</intent-filter>

I then modified SendIntent.java:

In checkSendIntentReceived:

...
if ((Intent.ACTION_SEND.equals(action) || Intent.ACTION_VIEW.equals(action)) && type != null) {
...

In readItemAt:
from

       Uri uri = null;

        if (intent.getClipData() != null && intent.getClipData().getItemAt(index) != null)
            uri = intent.getClipData().getItemAt(index).getUri();

        String url = null;

to

        Uri uri = null;
        String url = null;

        if (intent.getClipData() != null && intent.getClipData().getItemAt(index) != null)
            uri = intent.getClipData().getItemAt(index).getUri();
        else if (intent.getData() != null) {
            Uri copyfileUri = copyfile(intent.getData());
            url = (copyfileUri != null) ? copyfileUri.toString() : null;
        }

I also modified readFileName() to avoid some possible errors:

    public String readFileName(Uri uri) {
        try (Cursor returnCursor = getContext().getContentResolver().query(uri, null, null, null, null)) {
            if (returnCursor != null && returnCursor.moveToFirst()) {
                int displayNameIndex = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
                if (displayNameIndex != -1) {
                    return returnCursor.getString(displayNameIndex);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

Finally, I also have this in MainActivity.java:

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        String action = intent.getAction();
        String type = intent.getType();
        if ((Intent.ACTION_SEND.equals(action) || Intent.ACTION_VIEW.equals(action)) && type != null) {
            bridge.getActivity().setIntent(intent);
            bridge.eval("window.dispatchEvent(new Event('sendIntentReceived'))", new ValueCallback<String>() {
                @Override
                public void onReceiveValue(String s) {
                }
            });
        }
    }

I am pretty new at Android so I'm not entirely sure the code is correct and doesn't introduce other unwanted behavior.
