Android7.0调用相机时出现新的错误：

android.os.FileUriExposedException: file:///storage/emulated/0/photo.jpeg exposed beyond app through ClipData.Item.getUri()

解决办法：

                在Application的onCreat()方法中添加以下代码：

StrictMode.VmPolicy.Builder builder =new StrictMode.VmPolicy.Builder();

StrictMode.setVmPolicy(builder.build());

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {

builder.detectFileUriExposure();

}

或者

// android 7.0系统解决拍照的问题

StrictMode.VmPolicy.Builder builder =new StrictMode.VmPolicy.Builder();

StrictMode.setVmPolicy(builder.build());

builder.detectFileUriExposure();
