Depends on MorpheApp/morphe-patcher#105

Reduces memory requirements for bytecode patches and speeds up dex rebuilding.

Adds flag --bytecode-mode which can be set to

  • FULL - the legacy behavior, rebuilds all dex files, requires the most time and memory
  • STRIP_FAST - the default for CLI, fastest with least memory requirements but produces bigger APK files
  • STRIP_SAFE - intended default for Manager, faster than FULL with somewhat reduced memory requirements, not as performant as STRIP_FAST, similar APK file size to FULL

Hello there ~~
I am creating simple powershell script to patch morphe and crimera (piko). I am using this cli.jar https://github.com/MorpheApp/morphe-cli/actions/runs/24078851888/artifacts/6304612173

When I use arg --bytecode-mode and select STRIP_FAST (default for cli), patched X (twitter) crashing whenever I open it

But, when I select FULL (legacy behavior), patched X (twitter) is not crashed, opening normally.
This crash, is not happened on another apps like (morphe yt, yt music and reddit), also crimera (piko) instagram. Only on X (twitter) it crashed.

Okay, so probably an issue somewhere with writing the modified classes to new dex files. Will take a look soon

I get another bug with this PR
I am patching yt, ytm, and reddit. For yt and ytm, cli can not purge temp. files even without include --bytecode-mode parameter, but for reddit does. I am thinking of if you patching universal .apk, cli can not purge but if you patching bundles, cli does.

Then I testing this cli https://github.com/MorpheApp/morphe-cli/releases/tag/v1.6.4-dev.2
All works, can purge all apps which I am patching.

You are running on Windows, correct? The dex files are locked while the CLI is running, so the temporary files directory cannot be cleaned up until the dex files are closed or the CLI exits.

Please open a separate issue for this. I am doing development on Linux where file I/O semantics are different.
