android - Select Text and show meaning as pop up in MUPDF -
i using mupdf library , added features manual zoom in, zoom out , rating, setting brightness. doing long press highlighted text , have show meaning database. trying 2 things 1 clipboard or emulateshiftheld below feature android ics , jellybean. can body suggest on whether 1 thing work feature trying. because on long press can't able capture text. suggestions helpful.
