要在xml文件里面的provider 里面配置 android:grantUriPermissions="true" ，至于为什么看下面链接 https://developer.android.google.cn/reference/android/support/v4/content/FileProvider.html 以及FileProvider源码第380行 ` public void attachInfo(@NonNull Context context, @NonNull ProviderInfo info) { super.attachInfo(context, info);

    // Sanity check our security
    if (info.exported) {
        throw new SecurityException("Provider must not be exported");
    }

    if (!info.grantUriPermissions) {
        throw new SecurityException("Provider must grant uri permissions");
    }

    mStrategy = getPathStrategy(context, info.authority);
}
