My app uses ActivityGroup to build. There are four sub-activities in the ActivityGroup. No matter it is in which sub-activity, when input keyboard backspace, the sub-activity will always be changed to the first sub-activity that it is the first sub-activity when the app is run.
I cannot filter the backspace because there is an editview in one of sub-activity. And should allow user to input backspace. My android SDK is 4.4 and the target is Google APIs - API level 18.
Anyone has encountered this issue and know why?
