Seit OTA Update auf Marshmallow funktioniert meine Gyroscope-basierte App nicht mehr

Question

Ich habe mein Nexus 5 auf Marshmallow mit OTA aufgerüstet. Seit dem Update funktioniert die einfache sensorbasierte Aktivität nicht mehr. Der folgende Code tut, was es auf anderen Geräten tun sollte (Galaxy S4 Lolipop, AVD, ...)

Hat jemand das auch experimentieren? Vermisse ich etwas?

Hier ist der Code:

build.gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 22 
    buildToolsVersion "23.0.1" 

    defaultConfig { 
     applicationId "fr.rouk1.test" 
     minSdkVersion 16 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
}

Answer 1

Schließlich gefunden issue. Temporäre Lösung ist SENSOR_DELAY_GAME anstelle von SENSOR_DELAY_FASTEST zu verwenden.
