Android FileUriExposedException在Oreo中,android,android-intent,android-8.0-oreo,android-fileprovider,Android,Android Intent,Android 8.0 Oreo,Android Fileprovider,我正在尝试共享一个文本文件。我已经完成了使用FileProvider for>=Nougat共享文件所需的所有步骤,但仍然得到FileUriExposedException: Fatal Exception: android.os.FileUriExposedException: file:///storage/emulated/0/abc.txt exposed beyond app through ClipData.Item.getUri() at android.os.Str

我的共享代码是:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N || Config.ONLY_INTERNAL_STORAGE) {
            try {
                String packageId = context.getPackageName();
                return FileProvider.getUriForFile(context, packageId + FILE_PROVIDER, file);
            } catch(IllegalArgumentException e) {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                    throw new SecurityException();
                } else {
                    return Uri.fromFile(file);
                }
            }
        } else {
            return Uri.fromFile(file);
        }
并在意向书中添加了以下权限:

intent.setFlags(intent.FLAG\授予\读取\ URI\权限)

如果有人能帮我解决这个问题。谢谢

编辑: 我的意图代码如下:

intent = new Intent(Intent.ACTION_SEND);
        intent.setType("text/html");
        intent.putExtra(Intent.EXTRA_SUBJECT, "abc");
        try {
            intent.putExtra(Intent.EXTRA_STREAM, FileBackend.getUriForFile(activity, chatFile));
        } catch (SecurityException e) {
            Toast.makeText(activity, activity.getString(R.string.no_permission_to_access_x, chatFile.getAbsolutePath()), Toast.LENGTH_SHORT).show();
            return null;
        }
        intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

您不需要此检查(Build.VERSION.SDK\u INT>=Build.VERSION\u code.N)

目标版本需要是API 24或更高版本,而不是内部版本或android版本。
您将获得此异常,因为生成的uri仍然是file://

参考:我以前曾提到过这一点。正如我在问题中所说,我遵循了牛轧糖及以上的文件提供商方法。。仍然面临错误我认为检查不会影响结果,因为Oreo上发生了异常。它应该使用文件提供程序uri。
/***如果这是{@code文件://}uri,它将报告给
*{@link stritmode}.**@hide*/
public void checkFileUriExposed(字符串位置){if(“file”.equals(getScheme())&&&(getPath()!=null)&&&!getPath().startsWith(“/system/”){stricmode.onFileUriExposed(this,location);}
这是uri检查失败的地方。你能记录/调试你正在生成的uri吗@苏海尔汗
