问题描述
我的应用程序在大量电话中运行良好.但是，当我将其安装在旧的android手机中时，会抛出以下错误，并且在拍照时应用程序崩溃.
My application was working good in large number of phones. However, when I installed it in my old android phone the following error is thrown and application crashes while taking the photo.

推荐答案
Based on the code found here, its pretty self explanatory that the old device preview size is less than the size that you're trying to crop.
在我上面提到的代码中检查getPreviewCropRectangleUnzoomed函数.该函数的文档专门说明了错误的原因.从文档中.
Check the getPreviewCropRectangleUnzoomed function in the code that I have mentioned above. The documentation of the function says the cause of the error specifically. From the documentation.
/**
* Calculate the effective crop rectangle for this preview viewport;
* assumes the preview is centered to the sensor and scaled to fit across one of the dimensions
* without skewing.
*
* <p>The preview size must be a subset of the active array size; the resulting
* rectangle will also be a subset of the active array rectangle.</p>
*
* <p>The unzoomed crop rectangle is calculated only.</p>
*
* @param activeArray active array dimensions, in sensor space
* @param previewSize size of the preview buffer render target, in pixels (not in sensor space)
* @return a rectangle which serves as the preview stream's effective crop region (unzoomed),
* in sensor space
*
* @throws NullPointerException
* if any of the args were {@code null}
* @throws IllegalArgumentException
* if {@code previewSize} is wider or taller than {@code activeArray}
*/
检查零件-预览大小必须是有效阵列大小的子集；结果矩形也将是活动数组矩形的子集.声明预览大小必须小于实际活动数组大小.
Check the part - The preview size must be a subset of the active array size; the resulting rectangle will also be a subset of the active array rectangle. which declares the preview size must be smaller than the actual active array size.
在这种情况下，使用相机拍摄照片时，您可以考虑使用try/catch块.
In this case, you might consider having a try/catch block while you are taking picture using the camera.
try {
takePicture();
} catch (IllegalArgumentException e) {
Toast.makeText(this, "Your phone is too old", Toast.LENGTH_SHORT).show();
}
希望有帮助.
