V2flyNG is an Android-focused V2Ray client that can be installed directly from an APK package instead of relying on a desktop client. This guide explains the F-Droid-built V2flyNG 1.10.31 package, how to choose between arm64-v8a, armeabi-v7a, and universal builds, how to install the APK safely, and how to import a VMess or VLESS subscription. It also covers permissions, local VPN behavior, routing mode, DNS, and the most common installation and connection problems.
What V2flyNG Is and When It Makes Sense
V2flyNG is an Android client built around the V2Ray ecosystem. Its main purpose is to let an Android device use proxy profiles such as VMess, VLESS, Shadowsocks, and other compatible configurations through a local VPN interface. After a profile is selected and the VPN service is started, Android sends supported application traffic to V2flyNG, and the client forwards that traffic through the selected server configuration.
The application is useful when you want a lightweight mobile client with direct APK installation. The APK format is simply an Android application package; it is not a subscription format and it is not the same thing as a node configuration. Installing V2flyNG only installs the client. You still need to add a server profile manually, scan a configuration QR code, or import a subscription URL supplied by your service provider.
V2flyNG 1.10.31 is the package version discussed in this article. Because Android devices use different CPU architectures, the exact APK file matters. A package built for the wrong architecture may refuse to install, install without launching correctly, or be needlessly large if it contains binaries for every supported platform.
V2flyNG is best suited to users who already have a working VMess or VLESS subscription and want an Android client with a relatively direct configuration workflow. If you are still choosing a client, compare the protocol support, update frequency, routing controls, and Android version requirements rather than selecting an APK only because its filename looks familiar.
Best choice for most Android phones and tablets released in recent years. It normally provides the best compatibility with current 64-bit devices and avoids unnecessary native libraries.
Best for: modern Android devices
Designed for older 32-bit ARM devices. It can be useful when the device cannot run 64-bit native libraries, but it should not be selected merely because the file is smaller.
Best for: older 32-bit ARM devices
Contains native components for multiple ARM architectures, so it is usually the easiest choice when the CPU architecture is unknown. The file is larger, but it reduces the risk of choosing the wrong variant.
Best for: unknown architecture or quick setup
Choose the Correct APK Architecture Before Downloading
Most current Android devices use the ARM64 architecture, which appears as arm64-v8a in APK filenames or download lists. Older phones may use armeabi-v7a, a 32-bit ARM architecture. Some download pages also provide a universal package, which includes more than one native architecture and therefore takes more storage space.
The safest way to identify the correct package is to check the device information page or use a trusted system information utility. Look for entries named CPU ABI, Supported ABIs, or Instruction Sets. If the primary ABI is arm64-v8a, choose the arm64-v8a package. If it reports only armeabi-v7a, use the 32-bit package. If the device information is unavailable or ambiguous, the universal build is the practical fallback.
| APK Variant | Typical ABI | Package Size | How to Choose |
|---|---|---|---|
| arm64-v8a | 64-bit ARM | Usually smaller than universal | Use on most recent Android devices |
| armeabi-v7a | 32-bit ARM | Usually small | Use only when the device reports 32-bit ARM support |
| Universal | Multiple ARM ABIs | Larger | Use when the architecture is unknown |
Do not confuse Android version with CPU architecture. Android 11, Android 12, or Android 14 does not directly tell you whether the device requires arm64-v8a or armeabi-v7a. The operating system version and the processor ABI are separate properties. Also check the minimum Android version shown on the package information page; a correct CPU architecture cannot compensate for an operating system that is too old.
Conclusion: Identify the ABI, Then Pick the Smallest Compatible Package
For a recent device, arm64-v8a is normally the logical first choice. Use the universal package only when the ABI is unknown, and use armeabi-v7a when the device information clearly confirms 32-bit ARM support.
Install the V2flyNG 1.10.31 APK
The F-Droid-built 1.10.31 package can be installed as a normal Android APK. Before opening the file, make sure the download completed fully and that the filename matches the intended architecture. An incomplete transfer may produce an Android message such as “There was a problem parsing the package,” while an incompatible package may show that the application was not installed.
Android may block installation from a browser or file manager that has not been granted permission to install unknown applications. This permission is assigned to the specific source application, not globally to the entire device. For example, if the APK was downloaded with a browser, that browser may need permission; if you later open the same file with a file manager, the file manager may need separate permission.
Check the package
Confirm that the file is the V2flyNG 1.10.31 APK and that its ABI matches the device. Keep the file in local storage until installation is complete.
Allow the source
Open Android Settings → Apps → Special app access → Install unknown apps, select the browser or file manager, and enable permission to install unknown applications.
Open the APK
Open the Downloads folder, tap the V2flyNG APK, review the Android installer screen, and choose Install. Do not tap repeated files if the first installation is still processing.
Launch the client
Tap Open after installation, or find V2flyNG in the application list. Grant only the permissions required for importing files and starting the VPN service.
Remove install access
After setup, return to the same Special app access page and disable unknown-app installation for the browser or file manager if you do not plan to install another APK.
On some Android versions, the menu wording is slightly different. Search Settings for “Install unknown apps” if the exact path is unavailable. The Android VPN confirmation dialog is separate from APK installation. When V2flyNG starts its local VPN service for the first time, Android may ask you to approve a VPN connection; review the application name and accept only if it is the client you intended to run.
Import a Subscription or Add a Node
After installation, the next task is adding a usable configuration. A subscription URL is normally a web address that returns one or more encoded node profiles. A single VMess or VLESS link contains only one profile. A QR code is another way to transfer one profile without manually typing fields such as address, port, UUID, transport, and TLS settings.
V2flyNG menu labels can vary slightly between builds, but the workflow is generally the same: open the profile or configuration section, choose the add action, select subscription or manual import, paste the URL, save it, and update the subscription. Use a subscription URL from a trusted provider and avoid copying URLs from unverified messages, because the URL may contain an account identifier or access token.
| Import Method | Required Information | Best Use | Common Mistake |
|---|---|---|---|
| Subscription URL | One HTTPS or HTTP subscription address | Managing multiple nodes | Updating while the network is unavailable |
| QR code | A visible VMess or VLESS configuration code | Adding one node quickly | Scanning a blurred or incomplete code |
| Share link | A vmess://, vless://, or compatible link | Adding a single profile | Line breaks or spaces inserted during copying |
| Manual entry | Address, port, UUID, transport, TLS, and routing fields | Testing a custom configuration | Changing a server field that should remain exact |
For a subscription, look for an action such as “Subscriptions,” “Subscription groups,” or “Update subscription.” After the update finishes, return to the profile list and select one node. If the list is empty, check whether the URL was pasted completely, whether the provider requires a particular user agent, and whether the device can reach the subscription server without the proxy already running.
VLESS Profile
- Protocol
- VLESS
- Identity
- UUID
- Transport
- TCP, WebSocket, or other provider value
- Security
- TLS or Reality when supplied
Copy every field from the provider; do not replace a server name or transport path with a guess.
VMess Profile
- Protocol
- VMess
- Identity
- UUID
- Port
- Provider-defined port
- Transport
- TCP, WebSocket, or HTTP/2
Older VMess profiles may require the exact alterId, TLS, host, and path values supplied by the server.
Do not assume that every VLESS profile supports every V2Ray core feature. Some servers use Xray-specific options such as Reality or Vision. If V2flyNG cannot parse a profile or connects and immediately disconnects, compare the client’s supported protocol and transport fields with the provider’s requirements. A profile that works in v2rayN with a recent Xray core may not work unchanged in an older Android client.
Start the VPN and Configure Routing
V2flyNG normally uses Android’s local VPN service to capture application traffic. This does not mean that V2flyNG creates a remote VPN server. The application runs a local tunnel interface, applies its routing rules, and then sends selected traffic to the chosen V2Ray outbound. Android may display a VPN indicator while the service is active.
Start with the simplest mode: select one known-good profile, enable the VPN service, and test a few ordinary websites. Do not change DNS, routing mode, and transport settings all at once. If something fails, a simple configuration gives you fewer variables to investigate.
| Setting | Initial Recommendation | Why It Matters |
|---|---|---|
| Routing mode | Global or proxy-all for the first test | Confirms that traffic can pass through the selected node |
| Per-app mode | Enable only after global testing works | Limits the VPN to selected applications |
| DNS | Keep the client default initially | Avoids introducing a DNS failure during basic testing |
| Battery optimization | Exclude V2flyNG if Android stops it in the background | Prevents the VPN service from being suspended |
| Local proxy ports | Keep defaults unless another app conflicts | Changing ports is unnecessary for normal VPN mode |
Once the connection works, switch to rule-based or per-application routing if you need more control. In a per-app list, confirm whether the selected applications are included or excluded; different clients describe the same behavior in opposite ways. If a browser works but another application does not, check that application’s routing selection before changing the server profile.
Android battery management is a frequent reason for a connection that works briefly and then stops. Open Settings → Apps → V2flyNG → Battery and select an option that permits background activity when available. Also check whether the device manufacturer has a separate auto-start or background protection menu. These settings are device-specific, but the symptom is consistent: the VPN disconnects after the screen turns off or after several minutes in the background.
Troubleshoot Installation and Connection Problems
Most V2flyNG problems can be separated into three stages: the APK cannot be installed, the application starts but the profile cannot connect, or the profile connects but application traffic does not pass through the tunnel. Identifying the stage prevents you from editing server settings when the actual problem is an Android permission or ABI mismatch.
Error: App not installed
Cause and Fix:The APK may use an incompatible ABI, conflict with an existing package signature, or require a newer Android version. Confirm the architecture, uninstall an older conflicting build only if its data is no longer needed, and install the correct 1.10.31 variant.
Error: There was a problem parsing the package
Cause and Fix:The download is incomplete, corrupted, or incompatible with the Android version. Download the package again, verify the filename and file size, and check the minimum Android requirement.
Error: VPN permission was not granted
Cause and Fix:Android has not approved the local VPN service. Start the connection again and accept the system VPN confirmation for V2flyNG; if another VPN is active, disconnect it first.
Error: Subscription update timed out
Cause and Fix:The subscription host cannot be reached from the current network. Test the URL in a browser, check that it was copied completely, and retry through an already working profile if the client provides that option.
Error: Connected, but apps have no access
Cause and Fix:The profile handshake succeeded but routing, DNS, or per-app selection is blocking traffic. Test global routing first, then review DNS and application inclusion rules.
If the client connects and disconnects repeatedly, check the device clock before editing the node. TLS-based profiles can fail when the system date or time is substantially incorrect. Enable automatic date and time in Android Settings, reconnect to the network, and try the same profile again. For VLESS with TLS or Reality, also confirm that the server name, public key, short ID, and fingerprint fields were not altered during import.
If only one profile fails, test a second profile from the same subscription. One failed node usually indicates a server-side issue or an invalid profile. If every profile fails after the APK was installed successfully, inspect VPN permission, battery restrictions, DNS, and network access to the subscription or node address. Restarting the Android device can also clear a stale VPN service, but it should not be the only diagnostic step.
Which V2flyNG APK should I choose for a recent phone?
Choose arm64-v8a when the device reports 64-bit ARM support. Use the universal package if you cannot identify the ABI or want the simplest compatibility choice.
Does installing the APK include working proxy nodes?
No. The APK installs the V2flyNG client only. Add a subscription URL, scan a configuration QR code, import a share link, or enter a profile manually.
Why does Android show a VPN confirmation dialog?
V2flyNG uses Android’s local VPN service to capture and route application traffic. Approve the dialog only when the displayed application is V2flyNG and you intended to start the client.
What should I do when the subscription list stays empty?
Check the URL for missing characters, test whether it opens in a browser, verify the network connection, and retry the update after selecting a working profile if that option is available.
For the package and other client resources, use the site’s Download page. After installation, keep the first test simple: use the correct ABI, import one known-good profile, approve the Android VPN request, test global routing, and only then add custom DNS, per-app rules, or advanced transport options.
