Installing APK file programatically in android

Question

I am making an android app which allows me to download and install an .apk file.

Problem

I am able to download the file but not able to install it.

code to install .apk is as follows

Uri fileURI = FileProvider.getUriForFile(MainActivity.this,
                            BuildConfig.APPLICATION_ID + ".provider",
                            apkFile);

Intent installAPK = new Intent();

installAPK.setAction(Intent.ACTION_VIEW);

installAPK.setDataAndType(fileURI, apkFile,
                         "application/vnd.android.package-archive");

startActivity(installAPK);

Question

What am I doing wrong here? How can i install the downloaded .apk file?
