There is an intent filters for kml files that works but I have to receive data in the form of content scheme. The file was picked from File Commander.

data

content://com.mobisystems.fileman.RemoteFiles/ZmlsZTovLy9zdG9yYWdlL2VtdWxhdGVkLzAvTG9jYXRpb24lMjBUcmFja2luZy8yMDE5LTA0LTA0JTIwMTclM0EyNyUzQTU5Lmtt/bA/0

Now the problem is how to read this file? How can I handle this problem? Any help will be appreciated.

So far I tried

var uri = Uri.parse(trackString) 

FileInputStream(contentResolver.openFileDescriptor(uri, "r").fileDescriptor) 

contentResolver.openInputStream(uri) // not working

In manifest.xml

<!--Mime type set -->
            <intent-filter>

                <action android:name="android.intent.action.VIEW" />

at last it work , I was passing uri.path instead of uri through intent and getting wrong Uri.Parsing, so keep checking that mistake

contentResolver.openInputStream(uri) // works

    • actually i want to show the kml on the map. but it was a content:\ sceme so unable to parse ,so far i have tried var uri = Uri.parse(trackString) FileInputStream(contentResolver.openFileDescriptor(uri, "r").fileDescriptor) trackString = content://com.mobisystems.fileman.RemoteFiles/ZmlsZTovLy9zdG9yYWdlL2VtdWxhdGVkLzAvTG9jYXRpb24lMjBUcmFja2luZy8yMDE5LTA0LTA0JTIwMTclM0EyNyUzQTU5Lmtt/bA/0 not wrking contentResolver.openInputStream(uri) -> not working

    • at last i did it, the mistake was i was parsing uri from the uri.path which i was sending through intent bundle , so getting the wrong thing , so sending uri instead of uri.path works for me i will update the questions

Use ContentResolver and:

  • getType() to find out the MIME type of the content (since your <intent-filter> supports lots of types)
  • openInputStream() to read in the content

You get a ContentResolver by calling getContentResolver() on a Context.

     Cursor returnCursor = context.getContentResolver().query(yourFileUri, null, null, null, null);
     int nameIndex = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
     int sizeIndex = returnCursor.getColumnIndex(OpenableColumns.SIZE);
     returnCursor.moveToFirst();
     String name = (returnCursor.getString(nameIndex));        
     File file = new File(context.getCacheDir(), name);
     try {
        InputStream inputStream = context.getContentResolver().openInputStream(yourFileUri);
        FileOutputStream outputStream = new FileOutputStream(file);
        int read = 0;
        int maxBufferSize = 1 * 1024 * 1024;

        while ((read = inputStream.read(buffers)) != -1) {
            outputStream.write(buffers, 0, read);
        }
        inputStream.close();
        outputStream.close();
        Log.d(TAG, "Path " + file.getPath());
        Log.d(TAG, "Size " + file.length());
    } catch (Exception e) {
        Log.e("Exception", e.getMessage());
    }

  // To get the mime type of your file 


 public String getMimeType(Uri uri, Context ctx) {
    String mimeType = null;
    if (uri.getScheme().equals(ContentResolver.SCHEME_CONTENT)) {
        ContentResolver cr = ctx.getContentResolver();
        mimeType = cr.getType(uri);
    } else {
        String fileExtension = MimeTypeMap.getFileExtensionFromUrl(uri
                .toString());
        mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(
                fileExtension.toLowerCase());
    }
    return mimeType;
 }
