Dal momento che l'aggiornamento dell'OTA a Marshmallow la mia app basata sul giroscopio non funziona più

Question

Ho aggiornato il mio Nexus 5 a Marshmallow con OTA. Poiché l'attività basata su sensore semplice di aggiornamento non funziona più. Il seguente codice fa ciò che dovrebbe fare su altri dispositivi (Galaxy S4 Lolipop, AVD, ...)

Qualcuno ha sperimentato anche questo? Mi manca qualcosa?

Ecco il codice:

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' 
}

Finalmente trovato questo issue. Soluzione temporanea utilizza SENSOR_DELAY_GAME anziché SENSOR_DELAY_FASTEST.
