single instance of an activity in android
android, android-intent
Solution
In general you can use a combination of `Intent.FLAG_ACTIVITY_SINGLE_TOP`, `Intent.FLAG_ACTIVITY_CLEAR_TOP`, `Intent.FLAG_ACTIVITY_REORDER_TO_FRONT` and `Intent.FLAG_ACTIVITY_NEW_TASK` to accomplish what you want. However, which one (or ones) to use depends on the situation you have.
