I'm porting the following GCP IoT core function to Android Studio Gradle project.
createDeviceWithRs256
And when I just call this function, the application will crash.
GoogleCredential credential =
GoogleCredential.getApplicationDefault().createScoped(CloudIotScopes.all());
Is there I have no GCP credentials inside the App?
--
This is my setting for the gradle file
// My Platform is Android 7.0
defaultConfig {
applicationId "com.example.myapplication"
minSdkVersion 24
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
packagingOptions {
exclude 'META-INF/DEPENDENCIES'
}
dependencies {
...
implementation 'com.google.api-client:google-api-client:1.30.8'
implementation 'com.google.apis:google-api-services-cloudiot:v1-rev94-1.25.0'
...
}
And the error log is:
