I wanna create as music player. But image is not change and also it send both of signals( P and S). I dont know how can i make algorithm. Please help
Don't use a while loop, use an if then else statement instead like this
If play_pause.Image = playblue.png
Then do what you want for pause
Else do what you want for play

Thanks Taifun. Yeah it is correct but i cant this in mit app inventor. Which blocks are useful for this. How can i check what image a button has?
Check the properties of your image component... there is a block to get the image and to set the image...
A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
