MVP template not working in android 3.0

[mhdtouban]

Following the instructions, you have on the homepage. When I copied the MVP activities to the android studio directory the Android Studio Application got damaged. However, when I followed the same instruction on android 2.3 everything went well.

Hi there,

Indeed Android Studio 3.0 on macOS changes the way the app is signed and thus you cannot change any file inside the app bundle without breaking the signature.

I have a temporary workaround that consists in un-signing the app:

• Download this repo: https://github.com/steakknife/unsign
• Follow the instructions for building the unsign executable (just run make as the doc says).
• Run the unsign script with Android Studio executable and use the unsign version:

./unsign /Applications/Android\ Studio\ 3.0\ Preview.app/Contents/MacOS/studio
mv /Applications/Android\ Studio\ 3.0\ Preview.app/Contents/MacOS/studio.unsigned /Applications/Android\ Studio\ 3.0\ Preview.app/Contents/MacOS/studio

You can now execute Android Studio 3.0 and it should work !

Note that GateKeeper won't allow you to start AS 3.0 since it's not signed anymore, follow Apple's instructions to run it: https://support.apple.com/kb/PH25088?locale=en_US

Note that the method described in my previous answer seems to kinda break the auto update process.

The window tells that update is impossible but it seems to be working, it needs to be examinated

Hi @asrulsibaoel,

I checked your report and made a little fix, it's released with the 2.2.2 tag. You can pull the last code from the repo and it should work ok now.

Thank you for reporting the issue.
