I tried to run Android app with SNPE 1.36 on SDM660.
DSP runtime fall in my apk when;

try {

            final SNPE.NeuralNetworkBuilder builder = new SNPE.NeuralNetworkBuilder(application);

            builder.setModel(modelstream, modelSize);
            builder.setRuntimeOrder(DSP); //can't only DSP
            //builder.setRuntimeOrder(GPU); //can run builder build
            //builder.setRuntimeOrder(CPU); //can run  builder build
            builder.setOutputLayers("Postprocessor/BatchMultiClassNonMaxSuppression","add"); //MobilenetSSD non-quantized
            network =; //Error. Caused by: java.lang.IllegalArgumentException: None of the selected runtime targets are supported.
        } catch (IOException e) {



Benchmark tool was sucess with DSP runtime. 
SNPE1.36 document show 660 supported device with DSP(CDSP)

I use "snpe-release.aar" and "platform-vaildator.aar".
I thought needless to set environment(Snapdragon Neural Processing Engine SDK: DSP Runtime Environment (

I checked next.

  PlatformValidator(PlatformValidatorUtil.Runtime.DSP).RuntimeAvailable(getApplication()) ->false

  PlatformValidator(PlatformValidatorUtil.Runtime.DSP).runtimeCheck(getApplication()) ->false   

 PlatformValidator(PlatformValidatorUtil.Runtime.DSP).coreVersion(getApplication()) -> Hexagon Architecture V60


Are there need some setting?
