MMY India: the download on local networks
The channel file is 19.98 MB, which is 20,954,528 bytes exactly. On a city 4G or 5G connection that is a short download. On a daily data cap, a weak signal, or a prepaid pack that meters every megabyte, it is worth planning, because a cut-off file does not warn you cleanly. It parses as corrupt.
The size
19.98 MB on 4G, 5G, and a metered pack
19.98 MB is the APK alone. It is not the whole data cost. The first launch fetches assets over the network, and that second transfer was not sized, so this site will not invent a total. Budget the known 19.98 MB, then leave the phone on Wi-Fi for the first open if the prepaid pack is tight. A later open reuses what was fetched until you clear the app's data, which sends you back to the network.
On 4G and 5G in ordinary coverage the APK itself finishes quickly. The cases that hurt are the familiar Indian ones: a basement, a moving train, a village tower under load in the evening, a prepaid pack with a few dozen megabytes left, and a hotspot shared with a laptop. Start the download when the signal is stable, not when you are about to walk into a lift.
Wi-Fi is the better first choice when you have it, including a neighbour's connection or a workplace network you are allowed to use. Mobile data is fine when the pack can spare the file plus the unknown first-launch fetch. Neither path changes the file. The hash and the byte count are the same on Jio, Airtel, Vi or a broadband line. The network only affects whether the file arrives whole.
A cut-off file
Why a cut-off file parses as corrupt
An APK is a zip archive with a signature block. The installer reads the central directory, which sits at the end of the file. If the download stops early, that directory is missing or truncated, and Android reports a parse error. The message looks like the package is damaged or the Android version is wrong. Often the bytes simply never arrived.
Browsers differ in how honestly they report this. Some show a failed download. Some leave a partial file in Downloads with a finished-looking name. A retry that appends "(1)" to the name can leave both the stub and the real file, and tapping the stub produces the parse error again. Delete every partial copy before you start over.
Resume behaviour is the browser's, not the file's. Some Android browsers can continue an interrupted HTTP download. Some start again. The install host may or may not honour a range request; that was not measured, so do not count on a resume. If the download breaks, delete the partial file and run it again on a stable connection. A resumed file that the browser stitched badly is worse than a clean second attempt, because it can land near the right size and still fail the hash.
The byte check
The exact byte check
The finished channel file is 20,954,528 bytes. Not 20 MB, not 21 MB. A file manager that shows megabytes to one decimal place can round a truncated file into looking close enough, so read the byte count if the app offers it.
- On the phone, open the Downloads notification or the Files app, and look for the size in bytes. If you only see a rounded megabyte figure, do not treat a match to 19.98 as proof. A hash is the proof.
- On a computer, the file info panel shows the byte count, and
shasum -a 256followed by the file name prints the SHA-256. The recorded hash isb699d1480b19ec1fb28974c90df518bc7ff989e0900ec9fcc4beef7c353e6421. - A matching byte count plus a matching hash means you have the channel file. A matching version label on a different size means you have a different file, quite possibly the second build at 21,049,457 bytes.
The second file, mmy.apk, package com.Mymuqiueb.ineb, is a separate identity with the same application label and the same version name. It is not a "full" version of the channel file and not a repair for a truncated download. If your browser saved something that is neither 20,954,528 nor 21,049,457 bytes, it is not a file this site has a record for. Delete it.
After the byte check, the install still depends on the phone. Android 7.0, arm64, and an adult at the screen. Those are the device page and the age page. The SMS that follows a successful install is the OTP page.
