  Android will save the picture to see the album and timely
  Add Date : 2018-11-21      
  Android will save the image to the SD card, the album will not be there to this picture, because there is no update its index, generally you need to boot several times. Of course, we can manually update its index.

1, first save the file to the SD card.

String filePath = "xxx"; // full path

saveImgToSDcard (filePath);

2, increasing the Android internal media index.

public boolean saveImgToGallery (String filePath) {

boolean sdCardExist = Environment.getExternalStorageState (). equals (

android.os.Environment.MEDIA_MOUNTED); // determine whether there sd card

if (! sdCardExist)

return false;

try {

ContentValues ​​values ​​= new ContentValues ​​();

values.put ( "datetaken", new Date () toString ().);

values.put ( "mime_type", "image / jpg");

values.put ( "_ data", filePath);

Application app = DoctorApplication.getInstance ();

ContentResolver cr = app.getContentResolver ();

cr.insert (MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

} Catch (Exception e) {

e.printStackTrace ();


return true;


3, the refresh filePath upper level directory

MediaScannerConnection.scanFile (MyLanJingCode.this, new String [] {Environment.getExternalStoragePublicDirectory (Environment.DIRECTORY_DCIM) .getPath () + "/" + filePath.getParentFile () getAbsolutePath ().}, Null, null);

This will increase in time to see the pictures in the album.
