I’m sorry for your misunderstanding. I just think it will be more convenient for me to ask you questions in the future ---

Hi,Danie I have successfully compiled on cp-6.4 branch according to the configuration you said, However, after successfully building in online, I opened the document on my mobile phone, but the document did not load out. Have you ever encountered this situation? ![image](https://europe1.discourse-cdn.com/flex013/uploads/collaboraonline/original/1X/bfd1686c4d5994091fb31fcfc8fbb941b395cb62.png) ---

Hi, Good to hear you managed to build it. I haven’t encountered such a problem before, I only had a problem with text being invisible and that was due to building from a wrong branch. Maybe new code was added that caused this problem. Check other topics in the forum, maybe someone else experienced it. If I were you, I would try to build from master branch instead of cp-6.4, see if the problem persists. ---

Hi, The build core code was built from the cp-6.4 branch and I sent an email to the official to confirm it, I built the online part from the master branch, Let me try another solution to this problem, Danie, thank you for your patient reply ---

I hope we can continue to discuss other problems with Android compilation in the future ---

Hi everyone, I know it’s been long time, I need help to build Collabora on my own, I used these branches for both LibreOffice core and Collabora: Core: distro/collabora/co-22.05 Collabora: distro/collabora/co-22-05 All the builds and “make” already successfull, but when I tried to build in my Android studio, I always get this error: `ERROR:/home/ivanhutomo/Documents/Collabora2/android/build/app/intermediates/merged_res/debug/values-b+ca+valencia_values-b+ca+valencia.arsc.flat: AAPT: error: failed to deserialize` I already spent almost one week to find out where is the problem and also change and rebuild another branch as well. Below is my current gradle version: v7.0.2 Anyone could help? My plan is to use the lib of Collabora office as a document viewer integrated with my own app. Thank you so much.
