android.os.FileUriExposedException: file:///storage/emulated/0/Android/data/com.xygame.apps/cache/IMG1120583907.tmp exposed beyond app through ClipData.Item.getUri()

 

调用系统拍照时报错：

解决办法：

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();
}

偶然中尝试这个可以解决问题，具体报错为什么我还在研究，暂时记录下来
