Android 相机保存照Failed to find configured root that contains 终极解决方案（终于讲明白了）

android7.0以上调用相机
生成的文件路径跟指定的path不匹配问题（ mFile = new File(getExternalCacheDir(), "images/"+System.currentTimeMillis() + ".jpg"); 与 <external-cache-path name="hm_external_cache" path="images" /> ）
getExternalCacheDir()生成的路径为
/storage/emulated/0/Android/data/com.ruhai.yibei/cache/

完整代码如下

File mFile;
    Uri mImageUri;
    private void openCamera() {
        //创建文件用于保存图片
        mFile = new File(getExternalCacheDir(), "images/"+System.currentTimeMillis() + ".jpg");
        if (!mFile.exists()) {
            try {
                mFile.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        //适配7.0
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
            mImageUri = Uri.fromFile(mFile);
        } else {
            //第二个参数要和清单文件中的配置保持一致
            mImageUri = FileProvider.getUriForFile(PersonInfoActivity.this, "com.ruhai.yibei.provider", mFile);
        }

<?xml version="1.0" encoding="utf-8"?> <paths> <external-cache-path name="hm_external_cache" path="images" /> </paths>
