How to Fix PojavLauncher Code -1 Error (Step-by-Step Guide)
When you open PojavLauncher and the app suddenly closes or shows you a weird Code -1 error message, don’t panic. This error is super common. Most people get it right after installing the launcher, updating it, or trying to launch Minecraft Java for the first time. The screen freezes, jumps back, or just refuses to load, annoying, right?
The good news is that this problem is usually very small. A few quick checks, like reinstalling the runtime or giving the app permission, can fix it faster than you think. Most users solve it within 1–2 minutes once they know what caused it. Let’s break everything down into simple. Just follow the instructions.
What Is the PojavLauncher Code -1 Error?
Code 1 error means the launcher didn’t find the required files. Instead of opening Minecraft, PojavLauncher tries to load some important stuff in the background, and if even one tiny part is missing, the app gives up and throws you back to the home screen.
It doesn’t mean your phone is damaged. It just means something inside the launcher didn’t load the way it was supposed to. Most of the time, it’s because of broken runtime files, missing game folders, or denied permissions. Fixing those usually makes the error disappear instantly.
Why Does Code -1 Happen?
Code -1 happens when PojavLauncher can’t read the basic files it needs to run Minecraft Java edition. Most of the time, this error shows up because something in the launcher didn’t install the way it should. Maybe the runtime stopped halfway during download, maybe your internet glitched for a second, or maybe a file inside the Minecraft folder got messed up without you noticing.
It’s kind of like turning the key in a car and realizing one tiny part isn’t doing its job, the whole thing refuses to start. Another thing that causes this a lot is permissions. If Android doesn’t let the app touch your storage, PojavLauncher basically becomes blind. It can’t see the folders it needs.
Old pojavlauncher versions, big mod packs, or even a phone that’s running low on RAM can also push the error to show up. Basically, the app needs a few simple things to work, and when one of them is missing, it shows code -1error.
The Fastest Way to Fix Code -1
The quickest solution is to just reinstall the runtime. This alone fixes the issue for most people. Inside PojavLauncher, tap Install Runtime again. The download takes a minute, and once it’s done, many users see the error end immediately.
If that doesn’t work, check Storage Permission. Without this, PojavLauncher can’t open any of its folders. Go to Settings → Apps → PojavLauncher → Permissions
and enable Storage / Files & Media.
Reinstall the Runtime Files
The runtime is the heart of the PojavLauncher APK. If it’s broken or incomplete, the launcher will fail every time. A bad internet connection or a half-finished update can corrupt it without you even noticing. Try to reinstall the app:
- Open PojavLauncher
- Tap on the three dots
- Select Manage Runtimes
- Remove the old one
- Tap Install Runtime
It usually downloads in 1–2 minutes. After that, restart the app and try launching the game again.
Give All Required Permissions
PojavLauncher can’t do much if your phone blocks access to its own folders. This is one of the most common reasons for code -1 error. Check this, go to
- Settings → Apps → PojavLauncher → Permissions
- Turn on Storage or Files & Media
- If your phone shows “Allow access to all files,” enable it
After you allow the permission, restart the launcher. Most of the time, problems will be solved here.
Delete Broken Files and Restart the App
Sometimes a download gets corrupted, maybe your WiFi dropped, or the phone froze, and PojavLauncher is stuck trying to read those broken files. Removing those damaged folders gives the launcher a fresh start. To check this setting, go to:
Android > data > net.kdt.pojavlauncher
Delete only the folders you know are broken or empty.
Don’t delete everything unless nothing else works.
After cleaning up, restart the app. PojavLauncher will rebuild the files it needs.
Check Your Device Compatibility
Not every phone can handle Minecraft Java Edition. Older phones or low-end devices may crash before the game even tries to load.
The ideal requirements are:
- Android 8.0 or higher
- At least 3–4 GB RAM
- Enough free storage (1–2 GB minimum)
If your device is weak, close background apps or try using the lighter runtime. It can make a surprising difference.
Extra Tips to Avoid Code -1 in the Future
- Keep some extra storage free, because PojavLauncher works better on high space
- Avoid interrupting runtime downloads
- Don’t overload your phone with heavy mods
- Restart your device occasionally
- Use the latest stable version of the launcher
Regular cleanup helps PojavLauncher stay stable.
When Should You Reinstall PojavLauncher Completely?
Only do this when nothing else works. If all fixes fail, runtime reinstall, permissions, updates, and file cleanup, then your app installation is probably damaged. What to do next, just follow the simple steps:
- Uninstall PojavLauncher
- Delete leftover folders in Android/data
- After that, again install the latest version
- Open the app and let it create fresh folders
A clean reinstall often fixes these types of issues that refuse to go away.
