How make mock of final class?

Work in AndroidStudio. Want make mock of final class for AndroidInstrumentalTest with PowerMock. Added libs in gradle:

 androidTestCompile ('org.powermock:powermock-api-mockito:1.5.6')
 androidTestCompile ('org.powermock:powermock-core:1.5.6')
 androidTestCompile ('org.powermock:powermock-module-junit4:1.5.6')
 androidTestCompile 'org.mockito:mockito-core:1.10.8'
 androidTestCompile 'com.google.dexmaker:dexmaker:1.1'
 androidTestCompile 'com.google.dexmaker:dexmaker-mockito:1.1'

Make test class:

public class BluetoothTest extends ActivityInstrumentationTestCaseWithLogIn<PlanActivity> {


 public BluetoothTest() {
    super(PlanActivity.class);
 }


  @Override
  public void setUp() throws Exception{
        super.setUp();          
        BluetoothGatt gatt = PowerMockito.mock(BluetoothGatt.class);
  }
}

Stack trace:

I checked solutions from this issue, with no luck. Apparently solutions help with mockito-core, not powermock. It proved by another issue

I saw docs, then try added annotations @RunWith(PowerMockRunner.class) and @PrepareForTest(BluetoothGatt.class) on test class. Result :
