metaio SDK6不能在Android4.0上运行

Question

我已经将metaio SDK升级到版本6，并且在具有OS版本4.0的Android设备中遇到问题。我得到了以下错误。

Could not find class 'com.metaio.sdk.ARViewActivity$1', referenced from method com.metaio.sdk.ARViewActivity.onCreate
 Could not find class 'android.hardware.display.DisplayManager', referenced from method com.metaio.sdk.ARViewActivity.onPause
 Could not find class 'android.hardware.display.DisplayManager', referenced from method com.metaio.sdk.ARViewActivity.onResume

我找不到这个错误的原因。

Answer 1

权限似乎发生了变化

从…

<uses-feature
    android:name="android.hardware.sensor.accelerometer"
    android:required="false" />
<uses-feature
    android:name="android.hardware.sensor.compass"
    android:required="false" />
<uses-feature
    android:name="android.hardware.sensor.gyroscope"
    android:required="false" />

到这个

<uses-feature
    android:name="android.hardware.sensor.accelerometer"
    android:required="true" />
<uses-feature
    android:name="android.hardware.sensor.compass"
    android:required="true" />
<uses-feature
    android:name="android.hardware.sensor.gyroscope"
    android:required="true" />
