Forums - SNPE Image Classifier keeps stopping

Hi,

I am new to android and java to be precise. Currently I am trying to build the example inceptionv3 model based image classifier example in android studios.

I am able to build the image classifier project successfully but the apk (which is generated in ~/examples/android/image-classifiers/app/build/outputs/apk/ folder) on porting to emulator keeps on stopping. Please find more details below:

Following is the build.gradle:

apply plugin: 'com.android.application'

allprojects {
    repositories {
        jcenter()
        flatDir {
            dirs 'libs'
        }
    }
}

android {

    splits {
        abi {
            enable true
            reset()
            include 'x86', 'armeabi-v7a','x86_64'
            universalApk true
        }
    }

    sourceSets {
        main {
            jniLibs.srcDirs = ["libs"]
        }
        //androidTest.setRoot('src/test')
    }


    compileSdkVersion 26
    buildToolsVersion "26.0.0"

    defaultConfig {
        ndk {
            abiFilters "armeabi-v7a", "x86_64", "armeabi", "mips"
        }
        applicationId "com.qualcomm.qti.snpe.imageclassifiers"
        minSdkVersion 21
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile(name: 'snpe-release', ext:'aar')
    testCompile 'junit:junit:4.12'
}

I am dragging and dropping the apk into the emulator. Emulator details ar below:

Im using Pixel 2 API 29 emulator with Android 10 and CPU/ABI -> x86

Also I have used Pixel3a API 24 emulator with Android 7 and CPU/ABI-> x86.

Apart from the emulators I also tried to run the apk on my OnePlus 7 mobile. Still no luck :(

For all the above cases im getting this error "SNPE Image Classifier keeps stopping"

I also debugged and generated where is the cause of crash in logcat below. I'm not sure what is the error.
