# Android tips & tricks

## Sign the Android APK from CI
|
|
|
|
The [Github Actions Workflow](https://github.com/minetest/minetest/actions?query=workflow%3Aandroid+event%3Apush)
|
|
automatically produces an APK for each architecture.
|
|
Before installing them onto a device they however need to be signed.
|
|
|
|
This requires an installation of the Android SDK and `adb`.
|
|
```bash
|
|
.../android-sdk/build-tools/30.0.3/apksigner sign --ks ~/.android/debug.keystore \
|
|
app-arm64-v8a-release-unsigned.apk
|
|
# Enter 'android' (without quotes) when asked for a password
|
|
```
|
|
|
|
Note that the `debug.keystore` will not exist if you have never compiled an
|
|
Android app on your system (probably).
|
|
|
|
After that installing it will work:
|
|
```bash
|
|
adb install -r -d ./app-arm64-v8a-release-unsigned.apk
|
|
```
|
|
|
|
## How to get debug output from Minetest on Android
|
|
|
|
In case debug.txt isn't enough (e.g. when debugging a crash), you can get debug
|
|
output using logcat:
|
|
|
|
`adb logcat -s 'Minetest:*' '*:F'`
|
|
|
|
Note that you can do this even *after* the app has crashed,
|
|
since Android keeps an internal buffer.
|
|
|
|
A segmentation fault for example looks like this:
|
|
|
|
```

|
If you want get rid of previous output you can do that with `adb logcat -c`.

|
## I edited builtin, shaders, ... but nothing changed. Help!
|
|
|
|
You're probably hitting two problems:
|
|
* the build system only generates assets once
|
|
* the app only re-extracts assets when the version changes
|
|
|
|
Force regenerating the assets: `./gradlew app:clean`
|
|
|
|
Erase the app's memory of which version was installed: `adb shell run-as net.minetest.minetest rm shared_prefs/MinetestSettings.xml`
|
|
|
|
If this doesn't work you can also uninstall it using `adb shell pm uninstall net.minetest.minetest`. You will obviously lose your data.
|
|
|
|
Then build and install as normal and your changes should be applied.
