问题 I have an app that uses a specifically created binary (.gcsb) file type. These files are kept in a folder on the sdcard. At the moment they are moved on and off using ES file explorer or the phone manufacturer 'behave like a USB drive' transfer utilities. Clunky. What I want to to is be able to email the files to the phone, then to open the files as attachments from within gmail, which should fire up the app, which will then save them to the appropriate SD card folder. I've found some stuff

问题 I have got a small problem in an Android app I am working on : There are 3 activities namely A , B , C and the invocation is in the following order : A -> B -> C. While in C, when I press BACK button, it should go back to A[Instead of the B by default]. And pressing BACK in A will exit the program. I tried to call an intent from C to A. But in this case the call invocation gets into a loop : A -> B -> C -> A since the new activity is pushed on top of the stack. As a result, when BACK is
