Issue

I know single instance can be achived by setting android:launchMode="singleInstance" in menifest file. but i want to do it on run time . I think it can be achived by setting FLAG but not sure witch one.. plzz help me.. thanks in advance.

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.
