Fuse version 0.36.0 (build 11838) Copyright © 2017 Fusetools OS: Windows10 Home (Version 1607) Steps: Followed tutorial to learn how to make apps with fuse (hikr), preview is working perfectly, then i wanted to build it for my mobile (Honor8, EMUI5.1) and even if the build was successful, the APK won’t install To build the APK I typed: fuse build --target=Android --configuration=Release The build is successful, always, no errors, no warning, then moved the APK to my mobile and it just can’t be installed, i dunno if i’m doing something wrong or it’s not working… ---

What do you mean can’t be installed. What does it say? Do you get any error message? ---

Also, if you add `-r` to the build command then the app will be automatically deployed to your USB-connected device. ---

Can you try on a different android device? If it still doesn’t work, can you share the built .apk ? ---

I’ll try find some other android device with a different OS, i’m sharing the APK anyway: [https://drive.google.com/open?id=0Bz7cAl2ZLQ98dUFndDBlbENXOUk](https://drive.google.com/open?id=0Bz7cAl2ZLQ98dUFndDBlbENXOUk) ---

UPDATES: I also tried to download the code directly from your github (chapter4) and build it: $ fuse build -t=Android -c=Release Uno 0.47.12 (build 5229) Windows 10 x64 55058c5 Configuring (3.0 s) Compiling syntax tree (1.8 s) Generating code and data (13.5 s) Building Android app 2/2: hikr.apk Note: Some input files use or override a deprecated API. Note: Recompile with -Xlint:deprecation for details. (1:9) Build completed in 88.02 seconds But in the end, when i put it on my phone, it still doesn’t work -found another mobile device: Samsung S3, Android 4.4.2; Still doesn’t install, but it gives no error message (guess it’s a system issue) As i’ll be in the office i’ll try with a Samsung S7 updated to the last android version ---

Hi again ZioCain, We found a regression in how we handled signing of apps. When you build for release Fuse looks for signing info in the `unoproj` and if it doesn’t fine it then it is meant to fall back to using the debug-keystore. However since we moved to gradle this was no longer handled by the build system so we now make sure that Fuse handles it for you. We now have a fix internally and we are planning to make a patch release containing this fix. Thanks again for reporting this and all the details. ---
