捕获多张照片时出现的问题:应用程序停止响应,相机预览变为绿色并且没有保存图片

Question

我已经使用Android中的相机成功拍摄了单张照片.但是当我试图一次拍摄5张照片时,应用停止响应,相机预览变为绿色并且没有保存图片.我在堆栈跟踪中看到的内容如下(部分)

我takePicture在一个循环中调用该方法来捕获多张照片;

for(int m = 0 ; m < 6; m++) {

    mPrimCamera.takePicture(null, mPictureCallbackMet, mPictureCallbackMet);
}

我在运行Android 1.6的HTC Magic上做这个.我想,我用错误的方式拍多张照片.使用Android Camera API捕获多张照片的正确方法是什么？

我不确定android api是否支持突发模式.有一件事是肯定的,你不能只是takePicture()在这样的循环中调用.那只是滥用那些可怜的api.

拍下一张照片onPictureTaken()怎么样？(显然你必须跟踪拍摄的照片数量......)

也就像文档说的那样,不要认为它可以在每个设备上运行.

我在2011年写了上面的答案,从那时起Camera已经发展了

编辑:Camera2现在支持突发模式:https://developer.android.com/reference/android/hardware/camera2/package-summary.html
