The Android system also uses URLs to access various places that media is stored on the phone. Make sure you use the link that points to the actual file, not to players for the files, which is much more common on the Web, especially for music and videos. You can access files on Web using URLs, starting with, for example, setting the picture property of an image toĪnd similarly for music and videos. The drawback is that users won't automatically get them by installing your application. Using the SD Card provides a lot more space for media than trying to package things as assets. You'll have to use other applications or the Android phone file manager for that. It also doesn't (yet) include a way to list the files on the SDCard. Images and videos can be designated similarly.Īpp Inventor doesn't (yet) include any way to store files on the SD card. A complete song like this is too large for Sound to handle. Note that you'll want to use a Player component for this, not Sound. So you could designate the same file by setting the player source toįile:///sdcard/Music/Blondie/The%20Best%20of%20Blondie/Heart%20of%20Glass.mp3 Here you prefix the file name with file:///sdcard and use "URL encoding" for special characters.
The Android system also includes an alternative way to designe SDCard files as URLs. Make sure to specify the complete file name, including the "mp3". sdcard/Music/Blondie/The Best of Blondie/Heart of Glass.mp3Īnd starting the Player (assuming of course, that the song file is on the SDCard). You could play a song on your SDCard by setting the source of a Player component to You can access files on your phone's SD (secure digital) card using file names that begin with /sdcard. Bit you would probably not use them for complete songs or videos. They are good for small images and short audio selections. You can similarly use files names for sound (Sound or Player) or video (VideoPlayer).Īssets are the most convenient to use, but the space for them is limited to a few megabytes, because they must be packaged with the application. For example, if you have an image asset named kitty.png, you can use it as an image: just set the Picture property of an image component to the text kitty.png. You can also specify these in programs by their file name: just use the file name without any special prefix. You also specify them in the designer, which is convenient. Anyone who installs your application will have them, as part of the application. The sources labeled Media shown in the designer part of the application's assets are packaged with the application.
