我遇到权限的已知问题在Android中M. 当试图打开相机就出现以下情况例外：版本的Android M - 相机权限问题
java.lang.SecurityException: Permission Denial: starting Intent
{ act=android.media.action.IMAGE_CAPTURE cmp=com.google.android.GoogleCamera/com.android.camera.CaptureActivity }
from ProcessRecord{834e30b 8608:il.ac.shenkar.david.todolistex2/u0a126} (pid=8608, uid=10126) with revoked permission android.permission.CAMERA
这里是我完整的代码，它包括一个解决方法，我在这里找到并为其他人工作，但由于某种原因，我失败了。

}
}
}
break;
default: {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
}
}
权限的manifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature
android:name="android.hardware.camera.any"
android:required="true" />
<uses-feature
android:name="android.hardware.camera.autofocus"
android:required="false" />
请协助。
不能相信我忘了打电话'Camerapermission（）'。谢谢。 –
