MPASD Media player for SD chips - History

This page is in chronological order: Newest at top! Screenshots from Samsung A 10.

Update: 2020.1. 25: I have added a exit button which frees all memory buffers and closes. On the image window I have eliminated the "Info" button and now the file info always shows. I have eliminated the "Image Show" button and will provide that ability elsewhere.

Update 2020.11.17 Well its been almost two years now since I started working on a media player for tablets. Spring of this year I finally decided to give up on Kindle Fire tablets. They very so much from one device to the next and there is no way to know what you are purchasing. I found the Samsung tablets to be a much superior device to the Kindle and you dont have all the Amazon promotion to deal with. My first Samsung purchases were the tab A 7" (Android6.0) which are much inferior to the newer devices the tab A 8" and 10" (Android9.0) of which we now have many being used by our group.

Unfortunately neither of these devices are "pocket able" as they are over the 4.5" pocket width. For this reason alone I am continuing my search and presently testing 7" devices by Lenovo and Yankyo. They are both 4.5", in the $70 price range and Android9.0. I have found that the earlier versions of Android to be very slow with MPASD. Android ,9 however loads my Jazz collection of 20,000 files to a list in about 30 seconds. So far I have the Lenovo recognised but I can't find the USB drivers for the Yankyo yet.

I have now revised the graphic display window and put the control buttons at the top where they are easier to use. Most of the albums in our collection have associated graphhics (1920x1080 .jpg). This is the playback mode I use 90% of the time.

The main program window is a basic listView with file names listed for the contents off your SD chip. Remember MPASD looks for SD chip " /Media/" folder. The list can be sorted by date or artist. There are two play modes Random and Consecutive. Also you can invoke automatic picture display.

"Search" function searches for words or word fragments and accepts multiple arguments.

"Current" button scrolls the list to the currently playing selection.

"History" displays a list of all selections played in the current session.

"Camera" reads your SD chip /DCIM folder.

"Root" make current dir SD chip /Media/ and lists files.

"../" goes to parent and lists files.

I have tried to keep it simple.

Update 2020.03.18 - We have been using the program MPASD for many months now and I have not found need to recompile for some time. i have our Jazz collection, encoded to 192kbs MP3, 149g copied to 256g chips and they work on all my Samsung and Kindle devices. The Samsung 10" handles the 256g chip without problem but the "7 devices(older) require the chip to be reformatted to 200g. We have found the Bluetooth devices from Anker to be very good. Long battery life, good blue tooth communication 60ft., and very reasonable price all favor Anker. I have now created options in the export of MPprogs\MPTV.exe to convert our Photoshop .tif images to android compatible .jpg images. I have found the camera facility in the Samsung tablets to bo quite acceptable 5mp images so I have made MPASD able to display the most recent images with a single click. Unfortunately the 7" TAB A 6 Android 6 is no longer available being replaced with the 8" and !0" which are nice but to big for breast pocket. My 10" has Android 9 installed and a faster processor. Its a superior tablet $200+. Some 7" devices are still available for about $100 but they are Android 6.0 and should be avoided.

My program MPASD I have only tested on a few devices to date but it seems to be working good on both Kindle and Samsung devices. It is capable of creating a list of all 22,000 files which can be sorted by Performance Date, or Last Name of Artist. The list is searchable for words and or word fragments. The player has options for random/consecutive playback and image display off/on. We have now purchased 9+ Samsung tablets without a single problem. Recently discovered on the Samsung tablet a short press of the power button turns off the screen and MPASD continues audio playback without problem. In this mode I have played back continuously for over 16 hours on a single battery charge.

2018.12.25 I was recently given a Kindle Fire7 and the hardware really impressed me despite the fact that it is primarily intended as a marketing device for Amazon. The screen is very nice and the sound output is quite good from the 1/8" jack or Bluetooth so I have decided to re purpose this device as a portable off line media player. The big advantage of this device is cost $50. Our significant media collection now exceeding 100tb. I have adjusted the export function in MPTV our primary Windows program to create compatible files for the Kindle and now have started Android development of a Kindle player. I want to be able to play our un adulterated .wav files and display our HDTV images from our collection. These images are beautiful with personnel, song names, cover graphics and added photos and has taken over 20 years to compile. I have been able to display all this media quite nicely on the Kindle.

Update: 2019.05.30 - Well its been over four months now with all my excess time devoted to Android. Our music collection is now easily transferable to a Kindle Fire7. My program "SDman" is an offline music player which plays the media on the SD chip while displaying the associated .jpg image. 256gb chips work on some devices and not on others. (if the content exceeds 200gb) I have recently purchased several Fire7 32gb models and they seem to be quite good. I have recently been buying from sources that accept quick returns so I can test and return if necessary.

Test items: I have now tested 10+ devices and only found three that passed all these tests.

Does it recognize a near full 256gb chip

Does it understand intent.flagsAdd()

Is it recognized by the compiler. (presently using win7 or 10 and Android Studio3.5) several devices I have tested are not recognized making compiling impossible.

I would think that all Kindle Fire7's would operate the same after OS update I can testify this is not true. Go figure. I have now installed SDman and OS updates to about 10 devices with mixed results.

Hardware Devices:

I have found the Fire7's Bluetooth transmission to be quite good and the 1/8" audio jack very good the internal speaker is only fair and will leave you wanting.

The 1/8" audio jack to an amplifier is the best quality connection possible

I have now used numerous Bluetooth device:

Update: 2019.05.01 Kindle: Significant development work continues.....

I am finding there are important differences between various Kindle's.

James and Rob can you check your serial numbers on your Kindle. Trying to know

what serial numbers do what. James yours is a fully working machine. Rob I think

yours does not see the "intents" and returns you to the root after viewing an image.

I have copied the info directly from the web and as you can see there is

no discernible difference in the listings from which you purchase but BIG

differences in the hardware you might receive.
