Stackoverflow answering the same question: Here
Accepted answer from the question:
Turns out that I had to make the target and compile version to L which
meant that I could not run my app on older SDKs. If you want your app
to run on SDK 19 and lower you have to set your compile and target
version to 19 and your min SDK to whatever version you need.
Next you have to adjust your imports to the version that is compatible
with the SDKs that you have chosen to compile for. For example if you
want to use the v7 support library on sdk 19 you must import it like
this: compile compile 'com.android.support:appcompat-v7:20.+'
So yes, it is an issue with minimum SDK, I would recommend that you raise your minimum SDK to one that supports this.
To raise or change your minimum SDK, change the following code in your AndroidManifest.xml
<uses-sdk android:minSdkVersion="x"/>
