  • Android 刷新相册

    Android4.4之前:

    sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,Uri.parse("file://" + file)));  

    在4.4中会报权限异常

    Permission Denial: not allowed to send broadcast android.intent.action.MEDIA_MOUNTED from pid=2269, uid=20016
    那是因为Android4.4中限制了系统应用才有权限使用广播通知系统扫描SD卡

    之后

      

     public static void refreshAlbum(Context context, File file) {
    
    
            try {
                MediaStore.Images.Media.insertImage(context.getContentResolver(), file.getAbsolutePath(), file.getName(), null);
            } catch(FileNotFoundException e) {
                e.printStackTrace();
            }
    
    
            context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(file)));
        }
