Is there any way, or any audio player software that has the feature, to play/pause an audio file without opening the player app, e.g. via a floating button (like softkey) or a hard button? I am learning to speak a language. The text is in a PDF file, the audio is in MP3 files. I need to read the PDF (in Adobe reader, ezPDF, etc) while playing the audio, and need to play/pause the audio without having to close the PDF viewer, open the player, then go back.
I'm using a tablet. Its headset doesn't have any button (play/pause, volume control). The tablet only has 2 volume buttons, 1 home button, and 1 power/sleep button.
