篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Android异常篇 Fail to connect to camera service相关的知识,希望对你有一定的参考价值。
一、版本区别
在Java代码中添加运行时权限授权,在Activity的onCreate函数中添加如下代码
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)
requestPermissions(new String[] Manifest.permission.CAMERA, 1);
二、权限未添加
androidManifest.xml中没有添加Camera的权限申请,对策则是添加相机权限申请。
<uses-permission android:name="android.permission.CAMERA"/>
三、相机资源打开后未释放
if(mCamera != null)
mCamera.stopPreview();
mCamera.release();
mCamera= null;
