⚠️ Read this first: if you have not registered yet, use the registration link (e.g. "Sign Up") or invite code BINANBT — registering directly inside the app gets you none of the new-user rewards, and the $19,800 welcome package and 20% fee rebate will not apply. The package itself is free. Any "paid download" or "internal installer" is a scam.
Key takeaways (TL;DR):
- There are only two official sources for the Android package: Binance's own download page (including the official APK direct link) and Google Play. Mainland Android phones without full Google services should use the official APK. "Android download sites", "green" builds and "all-in-one packages" are not sources.
- Counterintuitive point one: a finished download is not an installable app. Android blocks sideloading by default, so allowing "install unknown apps" is a required step, not an error.
- Counterintuitive point two: the most common install failure is not a corrupt file, it is a signature conflict. If your phone already holds an app with the same package name but a different signature (an old build, a cloned app, a modified package), Android refuses to install over it. "App not installed" is actually a free authenticity check.
- Counterintuitive point three: confirm you can log in before you uninstall. Your assets live on the exchange, not on the phone, so uninstalling loses no coins — but if 2FA is not backed up, you may need a reset, and withdrawals are restricted in the meantime.
- Remember three numbers: a file name starting with
BNApp, a file of 321,076,391 bytes (file managers show 321 MB or 306 MiB — both are the same file), and the installed package name com.binance.dev.- The official APK does not auto-update. Download it again from the official site and install over the old version; only Google Play installs follow store updates.
The hard part of downloading the Binance Android package is not finding an APK — it is confirming that the file in your hand is the official one. The APK is the one distribution format on Android that anyone can build and anyone can modify: the icon can be copied, the splash screen can be copied, even the version number can be written to look identical. The download domain, the file size and the installed package name cannot.
This guide is about the package only: where to get it, how to get a complete file, how to install it, how to verify it, what to do when it will not install, when to install over the old version, and when you actually have to uninstall first. The domain, direct link, file size and package name were rechecked on 13 November 2026; the direct file was last updated on 26 October 2026.
Work out where you are stuck first
Each failure point has a different fix order. Find your row first instead of starting with "disable antivirus and try again".
| Your situation | Section to read | One-line answer |
|---|---|---|
| You do not know where to download; search results are full of download sites | Only two official sources | Use the official APK direct link or Google Play only |
| The download stopped halfway or the button does nothing | Interrupted downloads | Switch to the system browser, then check the byte count |
| "Install blocked / unknown sources not allowed" | Unknown-source settings by brand | This is the default defence; grant it only to the current browser |
| "App not installed" | Install failure table | Usually a signature conflict, not a corrupt file |
| It installed but crashes or shows a blank screen | Install failure table | Clear cache first, then uninstall and reinstall |
| You are not sure the installed app is official | Four-layer security check | Package name and size are more reliable than the icon |
| You want the newest version | Install over / uninstall / update | A sideloaded build never auto-updates; download it again |
Only two official sources for the Binance Android package
Choose the source first; installation comes second. Get the source wrong and every later check is a health inspection of a fake.
| Source | Location | How it updates | Who it suits | Risk |
|---|---|---|---|---|
| Official download page / direct link | The binance.com download page; the package is distributed by Binance |
Download again and install over the old version | Mainland Android phones without Google Play | Low, if you verify the source |
| Google Play | The Binance listing in the Play Store | Automatic or manual store updates | Android with full Google services | Low, still verify the developer |
| Download sites / cloud drives / group files | "Android download sites", "green versions", "internal builds" | Unclear | No one | High, repackaging and bundling are common |
The official Android direct link is https://download.bsmkweb.cc/pack/BNApp_F0002087.apk?utm_medium=web_share_copy — paste it into a mobile browser and the download starts. When rechecked on 13 November 2026, the file was 321,076,391 bytes, of type Android package, last updated 26 October 2026, with a name starting with BNApp. Remember these; the verification later depends on them.
⚠️ Why bother about the source? Crypto losses are essentially irreversible. Once a fake package is on your phone, it looks almost exactly like the real app and waits for you to type your account, password and verification codes before moving your assets out. Android's freedom to install is also the freedom to be compromised; no platform underwrites this step for you.
How to recognise the official site itself, and how to tell mirror and phishing pages apart, is covered separately: Binance official website 2026: official URLs, app download and registration links.
Why do some people say the package is only 100-odd MB?
The same app reports a different "size" on different channels.
- Official direct link: 321,076,391 bytes. A file manager using MiB shows about 306 MiB; one using MB shows about 321 MB. They are the same file, not two versions.
- Google Play: the store shows a "download size" that is compressed and split per device model, usually far smaller than the complete APK. The installed footprint is larger than either number.
- Third-party sites: often an old build, a stripped package or a modified one; 100-odd MB is common and tells you nothing about the official package.
So the only standard for "how big is the official package" is: downloaded from the official APK direct link, the size matches, and the installed package name is com.binance.dev. Do not take a third-party site's size as the reference, and do not guess authenticity from the version number.
Interrupted downloads and dead buttons: get the whole file
The most common download failure is not "I could not find the link" but "the file never finished" — and it only shows up at install time, which makes people blame the package.
Work through this order:
- Switch browsers. Opening the Binance download page inside WeChat or QQ commonly ends with the page blocked, an "access stopped" notice, or a download button that does nothing. That is the in-app browser restricting downloads, not a problem with the package. Copy the link into the system browser (Chrome, Edge or the phone's built-in browser).
- Do not use "APK accelerator" downloaders, cloud-drive transfers or group-chat files. Every one of those steps can swap the file, and you will not be able to tell afterwards.
- Check the byte count after downloading. Long-press the package in a file manager and open its details: it must be 321,076,391 bytes. Clearly smaller means the download did not finish — delete it and download again; do not install a half file.
- Downloading on a computer and transferring is fine. Copy it over USB or with the system's own file transfer, then check the size again; an interrupted transfer also produces a smaller file.
- Do not lock the screen or switch networks mid-download. Battery saver can cut the transfer in the background and leave you with a package that will not install.
Browser "resume" is not reliable. A resumed download may not produce a file identical to the original; the safest move is to delete it and download again. The package is a one-time download — do not save time here.
Official install in four steps
Installing Binance on Android takes four steps. Do not reorder them, or you will troubleshoot on top of a mistake.
- Get the package. Open the official direct link in a mobile browser, or use the Android option on the official download page. Do not switch networks or let the screen lock during the download.
- Allow the install. On a first sideload, Android says the install is blocked or unknown sources are not allowed. That is not a bug — it is the default defence. Grant permission to the browser you are using.
- Install the package. Find
BNApp_...apkin the Downloads folder and tap it. The Binance icon appears on the home screen when it finishes. - Check the package name. Open Settings → Apps → Binance → App info; the package name must be com.binance.dev. Most tutorials skip this, but it is the only hard evidence that you installed the right app.
Afterwards, go back and switch "install unknown apps" off for that browser so you do not accidentally install something else later.
Security check: four layers
A fake package can copy the interface but not the file attributes. Check the four layers below from the outside in; if any layer fails, uninstall and start again.
| Layer | Genuine | Fake | Where to look |
|---|---|---|---|
| Source | Official APK direct link or the binance.com download page |
Third-party download sites, cloud drives, words like "accelerator", "mirror" or "cracked" | Source before downloading |
| File | 321,076,391 bytes (about 321 MB / 306 MiB), type Android package (application/vnd.android.package-archive) |
A few MB, tens of MB, or a zip file or downloader | Long-press the file in a file manager |
| Install | Package name com.binance.dev | A different package name, or a conflict with an installed app | Settings → Apps → App info |
| Behaviour | Never asks for a recovery phrase, never asks you to disable antivirus or share your screen | Immediately asks you to "import recovery phrase" or "restore wallet" | First launch |
The behaviour layer is the most overlooked and the most decisive. Binance is a custodial exchange: your assets sit in an account and there is no private key in the app, so the real app never asks for a recovery phrase. A "Binance app" that does, no matter how well it matches the first three layers, is fake.
You do not need a signature-inspection tool for this. Do not download a "signature checker" from a third-party site to verify an APK — that is a new risk vector in itself. The four static checks above already cover the overwhelming majority of fakes.
Install failures: read the error message first
Android only produces a handful of install errors, and each one has a different fix. Match the message, not the panic. Do not start by disabling antivirus — that hides the real cause.
| Message (wording varies by brand) | Real cause | What to do |
|---|---|---|
| There was a problem parsing the package / corrupt package | Interrupted download, incomplete file | Delete the file and download again; do not reuse a half-finished one |
App not installed (log often shows INSTALL_FAILED_UPDATE_INCOMPATIBLE) |
Same package name, different signature: an old build, a cloned app, a modified package | Uninstall the old and cloned versions, reboot, install the official package |
App not installed (INSTALL_FAILED_VERSION_DOWNGRADE) |
The package is older than the version already installed | Use the latest official package; uninstall first if you truly need to downgrade |
| Insufficient storage | The package is 321 MB (306 MiB) and expands after install | Free at least 1 GB before installing |
| Install blocked / unknown sources not allowed | Permission missing, or granted to the wrong app | Grant it to the current browser or file manager only |
| Blocked by antivirus | A false positive, or the package is genuinely not official | Run the four-layer check; whitelist only after it passes |
| Installed but crashes or shows a blank screen | Unsupported system version, leftover data, network path | Clear cache, reinstall, update the OS; try another network |
Here is the counterintuitive part: a signature conflict can be good news. If the old package came from the official site and the new one did too, it should install over. A conflict usually means one of the two came from somewhere else — and the fact that Android compared the signatures is more reliable than any written claim.
For deeper download-path issues and update issues, see Binance download failure troubleshooting and Binance latest version and update failures.
Install over, uninstall and reinstall, or update
Same app, three routes, three different outcomes.
- Install over the old version: tap the new package. Your login usually survives; this is right for an official package upgrading another official package. It only works when the signatures match.
- Uninstall and reinstall: remove the old app first. This clears cloned apps and modified packages and is the standard fix for signature conflicts. The cost is local data and a fresh login.
- Update: a sideloaded build never auto-updates; you must fetch it again from the official site. Only Google Play installs update through the store.
Before you uninstall, confirm two things: you can receive login codes, and 2FA is backed up (the authenticator can be migrated, or you hold recovery codes). Your assets will not disappear with the app, but losing 2FA means a reset process, and withdrawals are restricted while it runs — which is why "uninstall to clear some cache" is a decision people regret.
⚠️ Never get an old version from an "APK archive" site. Those packages cannot be traced to an official source or signature, and "I need to roll back" is exactly the mindset phishing packages exploit. If the current version is incompatible, update the OS or use the web version instead.
Can the official APK and the Google Play build replace each other?
Not necessarily — it depends on the signature. A Play-distributed build may be re-signed through Play App Signing and is not signed with the same key as the official direct APK; switching from the Play build to the official package then fails with "app not installed".
The sequence:
- Confirm you can log in and that 2FA is backed up.
- Uninstall the Play build (assets are in your account, so nothing is lost).
- Reboot, then install the official APK.
- Check the package name
com.binance.devand log in again.
The other direction can conflict too. Do not keep tapping "install" to preserve your session; a conflict is a conflict, and uninstalling is the fastest route.
Unknown-source settings by brand
If you cannot find the switch, use search instead of menus. Type "install unknown" or "external source" in the search box at the top of Settings.
| Brand | Settings path |
|---|---|
| Xiaomi / Redmi (HyperOS / MIUI) | Settings → Privacy & security → Special permissions → Install unknown apps; some MIUI builds use Password & security → System security → Special app permissions |
| Huawei / Honor | Settings → Security → More security settings → Install apps from external sources; with Pure Mode on, exit temporarily or choose "Install anyway" |
| OPPO / OnePlus / realme (ColorOS) | Settings → Security → Install apps from external sources; some versions use Password & security → System security |
| vivo / iQOO (OriginOS) | Settings → Security → More security settings → Install unknown apps |
| Samsung (One UI) | Settings → Security and privacy → turn off Auto Blocker first; then Apps → Special access → Install unknown apps |
Grant it only to the browser or file manager you are using. Opening it for all apps at once removes the sideload defence entirely.
Antivirus false positives: prove it is official first
Domestic security software routinely flags sideloaded exchange packages, but "flagged" and "fake" must be handled separately.
- Run the four-layer check first. Domain, size, package name and behaviour must all pass before you call it a false positive.
- Then whitelist it. Add the package or app to the trusted list rather than switching real-time protection off.
- Watch the other direction. If the alert names a specific Trojan or spyware and the source was not official, it is most likely real — delete it and ignore any advice to "disable antivirus and install anyway".
After installing: registration order matters more than the version
Installing correctly is only the entry ticket; the order of the next steps decides whether you redo work. The recommended sequence is: download → register (through the registration link or invite code) → KYC → 2FA and anti-phishing code → first deposit.
Only "download" and "register" are irreversible: a wrong package means uninstalling and starting over, and a registration that did not bind an invite relationship can rarely be fixed later. The full account opening flow is in Binance registration guide, and the four security settings in Binance account security.
After logging in, do these four things in order:
- Enable 2FA, preferably with an authenticator app rather than SMS alone.
- Set an anti-phishing code; any "Binance email" without it is phishing.
- Review logged-in devices and log out anything unfamiliar.
- Configure a withdrawal whitelist; new addresses take time to activate and that delay blocks most theft attempts.
If the source of your package is in doubt, treat it as "the account may be compromised": change the password, reset 2FA, check API keys and withdrawal history.
💰 Binance referral benefits: invite code BINANBT
Downloading and registering are free; the long-term cost is trading fees. Bind invite code BINANBT when you register and get a 20% fee rebate. Key point: do not register inside the app — that binds no referral relationship, and neither the $19,800 welcome package nor the rebate will apply. Use the registration link or enter BINANBT manually.
- Rebate: 20% of every trading fee, for as long as the relationship holds.
- Welcome package: up to $19,800, unlocked by tasks, not cash on sign-up.
- How to confirm: the invite code field must not be empty, and the referral relationship is visible in your account after registering.

FAQ
I cannot open the Binance download link inside WeChat. Is the link dead?
Usually not. The in-app browsers in WeChat and QQ block exchange download pages, so the page fails to open or the download button does nothing. Copy the link into the system browser (Chrome, Edge or the built-in browser); if it still fails, try another network.
My download stopped halfway. Can I resume it?
Not recommended. A resumed browser download may not be identical to the original file, and the failure only appears when you tap install. Delete the partial file, download again, and check the size is 321,076,391 bytes — anything less means it did not finish.
Which file is the official Binance Android package?
The official Android package starts with BNApp, is distributed by Binance, and was rechecked at 321,076,391 bytes on 13 November 2026. The number in the file name is a distribution ID, not a version; to get the latest version, download it again from the official site.
Does "app not installed" mean the package is corrupt?
Usually not. The most common cause is a signature conflict: an old version, a cloned app or a modified build with the same package name is already on the phone. Uninstall those, reboot, and install the official package. Confirm you can log in and that 2FA is backed up first.
Can the Google Play build and the official APK be installed over each other?
Not necessarily. The Play build may be re-signed through Play App Signing and is not signed with the same key as the official APK, so installing over it fails with "app not installed". Confirm you can log in, back up 2FA, then uninstall and reinstall.
How do I confirm the installed app is official?
Check three things together: the package name in Settings is com.binance.dev; the package file is 321,076,391 bytes; and the app has no entry for importing a recovery phrase or restoring a wallet. The third one matters most — the real Binance app never needs a recovery phrase.
Does the official APK update itself?
No. A sideloaded build must be downloaded again and installed over the old version; only Google Play installs follow store updates. Installing over the old version keeps you logged in unless there is a signature conflict.
Can Huawei and HarmonyOS phones install this Android package?
HarmonyOS 4.x and earlier still run on Android and can install it; HarmonyOS NEXT (5.x and later) no longer supports Android APKs and needs the native build — see Binance HarmonyOS download and install.
Verification note
The official download domain, Android APK direct link, file size (321,076,391 bytes), file type (application/vnd.android.package-archive) and package name in this article were rechecked on 13 November 2026; the direct file was last updated on 26 October 2026. Binance may change the download page structure, package size or supported systems; the official download page and the installed app's information always take precedence. This article does not provide third-party packages and does not recommend disabling system security to force an install. Nothing here is investment advice.
Last reminder: a package can be downloaded again, but a phone handed to someone offering "remote installation help" is usually a loss you cannot undo.
