build errors with renderscript using Android studio 0.2.3; 4.3 SDK

Question

I receive the errors below while upgrading to the newest studio (0.2.3) and newest SDK (4.3). I have a few non-root functions in my renderscript file and the compiler gives a error that these functions are not supported in SDK levels 11-15. Therefore, I set my level to 16 in the build.gradle and the manifest file. I am not sure why I have to do this twice. Maybe the manifest is not used anymore. After changing to 16 level I noticed that the error below still shows "-target-api 11". How do I get around this problem? I had these non-root functions in my renderscript file before this upgrade.

Thanks,

Answer 1

1. You should use the SDK version and build tool of same version.

2. In the project property file add the below statement .

   renderscript.target =18
   renderscript.support.mode = true
   sdk.buildtoos="choose depanding on the API level"
   

3. Classes using RenderScript , add the below import statement.

   import android.support.v8.renderscript.*;
   

Please check may be this will be helpful .

Answer 2

Can you post the function signatures for the 3 functions causing issues? A large number of warnings and errors were added to catch minor mistakes. If this is an internal function not called from Java code, you probably just need to mark it static.
