Android 9.0自动更新 安装包解析错误 java.lang.SecurityException: Permission Denial_java.lang.securityexception: permission denial: re

在android 9.0自动下载更新时 遇到 安装包解析错误

在android 7.0使用的是同一套框架却没有问题？
然后通过adb命令抓取一下异常发现

发现Android9.0是需要权限读取fileProvider和uri的
于是我看了一下三方框架的源码，确实没有加权限

private Intent installIntent(Context context, String path) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addCategory(Intent.CATEGORY_DEFAULT);
        String fileProviderAuthority = getFileProviderAuthority(context);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N && null!= fileProviderAuthority) {
            Uri fileUri = FileProvider.getUriForFile(context, fileProviderAuthority, new File(path));
            intent.setDataAndType(fileUri, "application/vnd.android.package-archive");
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        } else {
            intent.setDataAndType(Uri.fromFile(new File(path)), "application/vnd.android.package-archive");
        }
        return intent;

于是我就扒了一下源码对其进行修改

        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
