First, decompile apk file with [apktool](https://apktool.org):
|
|
|
|
```
|
|
apktool d <file_name>.apk
|
|
```
|
|
|
|
Replace assets or edit *Manifest.xml*. [smali2java](https://github.com/AlexeySoshin/smali2java) can be of use for code modifications.
|
|
|
|
Recompile apk:
|
|
|
|
```
|
|
apktool b <file_name>
|
|
```
|
|
|
|
Alignment is necessary for modern android versions (I beleave, 30+ SDK):
|
|
|
|
```
|
|
zipalign -v -f -p 4 <file_name>/dist/<file_name>.apk aligned-<file_name>.apk
|
|
```
|
|
|
|
Create a signing key. Fields values do not matter. Especially for personal use.
|
|
|
|
```
|
|
keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 1000
|
|
```
|
|
|
|
Actually sign apk with it:
|
|
|
|
```
|
|
apksigner.jar sign -ks my-release-key.keystore --ks-key-alias alias_name aligned-<file_name>.apk
|
|
```
|
|
|
|
It will overwrite the provided apk with a signed one.

We're awesome! |
