ANDROID 读取系统图片失败

Question

我是先获取了系统图库里的某个图片的路径 path，然后
File file = new File(path);
InputStream is = new FileInputStream(file);
然后就报错W/System.err: java.io.FileNotFoundException: /storage/emulated/0/Tencent/QQ_Images/null-52a51a941f2792db.jpg: open failed: EACCES (Permission denied)

你的tagetsdk大于等于23吗？如果是的话，需要动态申请权限，在manifest里申请是不行的
