this is the logcat, not sure if this will help
You are probably running on a phone that is lower than API 11, which is when the method
getActionBar
was introduced. If you need to run on devices lower than API level 11, then you will need to guard against executing those calls that only exist on newer API levels, or else use a compatibility library such as ActionBarSherlock or Action Bar Compatiblity. (See this thread for a discussion of the differences between these two.)Change the
android:minSdkVersion="8"
toandroid:minSdkVersion="11"
and all the newer API calls that you are making will light up as errors. This will make it easier to locate those parts of your code that need attention.For api < 11 you have to use:
Algo make sure you are using appcompat, add this on build.gradle, the 19.+ should be your project target version.
Also if you are using invalidateOptionsMenu() for navigation drawer use this instead:
I faced this same issue before. I just replace
with
This is because the
getActionBar
is a method of api 11, but you can do this:and in the activity class add this suppress Lint:
On your MainActivity class, you call
getActionBar()
which is not available to your application.Your
android:minSdkVersion
is set to 8 (API-8), which does not providegetActionBar()
(only since API-11).You should use ActionBarSherlock for good backward compatibility, or set
android:minSdkVersion
but then all devices < API-11 won't be targeted.Use
getSupportActionBar
available with support library v7 as described here on the6. Retrieve the Action Bar
sectiongetSupportActionBar documentation
