There seems to be error is you LSPosed logs, please upload the complete logs of debug build. |

I was using release build before, I didn't know it didn't have debug info with verbose logs enabled. Following is the log after hooked app is started, I cleared the log before I started it. Hopefully that's enough, if you need logs from earlier in the boot, let me know. Note that |

You surely cannot hook any method you want in an Android application. Instead, you should analyze the correct execution flow of the target app and set up the hooking points properly. This is not a problem of LSPosed, it is your task while designing a module. |

I cannot hook methods if I looked more into the issue. Following is the normal stack and logs for the hooked app if it does not specify Following is the stack and logs for the hooked app if it does specify The issue is that if the app specifies an app component factory, then it can add app specific code to package androidx.core.app;
public class CoreComponentFactory extends android.app.AppComponentFactory {

I haven't looked too deeply so may be missing something too. |

That is an interesting proposal, I will consider it once the refactoring of LSPosed is done. Personally, I don't think hiding root via LSPosed could help, it is usually better to write zygsik modules directly. Alternative, try maybe this one: https://github.com/Mrack/TInjector_Symbi |

That would be great, thanks. I will try looking into testing my design when I get time, busy with termux rewrite work myself. If you override the methods used for root checks in the app itself, then it can work, I have already done it with apktool decompile/recompile for many apps, but APK sources don't always recompile due to apktool/resource issues, doesn't work for native checks, and requires changing signing keys, which apps often have additional checks for. So LSPosed way would be easier, especially with hooked app upgrades, as only obfuscated class/function names would need changing in module. Trying to hide root with modules and root solutions has become a cat and mouse game and lot of the solutions are closed source, LSPosed would be easier for personal use case. Thanks, I will look into it. |
