android - java.lang.RuntimeException : takePicture failed in lollipop and marshmallow 错误

Question

我正在尝试制作一个应用程序，它在单个 Activity Intent 上拍摄正面图像然后拍摄背面图像，我的前置摄像头代码与下面相同并且工作得很好我什至调用完成来破坏表面和内部 onSurfaceDestroy() 我调用下面给出的 initBackCam() 方法，它再次正常工作，直到 onSurfaceChanged() 内的 onSurfaceChanged() 我正在调用 pCamera.takePicture(null,mPictureCallback,mPictureCallback) 抛出异常 takePicture Failed

注意:这段代码工作正常，直到 kitkat 在 lollipop 和 marshmallow 中失败了

我尝试在前置和后置摄像头之间延迟，我尝试将后置摄像头的代码放在不同的 Activity 中，但它仍然会抛出相同的错误，我已经释放了摄像头并在拍照前调用了 startPreview() 但它仍然抛出相同的错误错误

我使用了以下权限

<uses-permission android:name="android.permission.CAMERA"/>
<uses-feature android:name="android.hardware.camera" android:required="false" />
<uses-feature android:name="android.hardware.camera.front" android:required="false" />
<uses-feature android:name="android.hardware.camera.back" android:required="false" />

Answer 1

试试这个

添加:

SurfaceTexture st = new SurfaceTexture(MODE_PRIVATE); 
pCamera.setPreviewTexture(st);

之前:

pCamera.startPreview();

takePicture failed
