Hi, I’m newer to Juce and would like to use juce to create android studio projects, but compile failed,errors like

Hmmm I can’t seem to re-produce this. Which Android SDK version are you using? Which build-tools version?

3

Thanks for your reply, I test it on android studio 2.2.2 and gradle 2.14.1 ,maybe I changed something this problem occurred, but after I re-produce new project with JUCE4.3, and use gradle build command anything works well. I will re-test this case.

Hi fabian,
I have repeated this case when I open one old juce project(maybe created with JUCE4.0) and created android studio project, I can’t compile with gradle in android studio, some errors like:

error found in line like:

You probably have a space in you activity name or something like that.

6

I set Android activity class name as “com.tizer.NewProject” in juce 4.3, I checked it.

7

Just set it to NewProject.

8

OK, I will test right now and report result to you. thanks

Oh, sorry, I can’t fix this problem.

Hi,

I had exactly the same problem this morning trying to compile one of my apps under Android Studio/Windows.

The cause is the declaration of JUCE_ANDROID_ACTIVITY_CLASSPATH in app/build.gradle.

Projucer creates this line, causing the build error:
cppFlags.add("-DJUCE_ANDROID_ACTIVITY_CLASSPATH=“com/brand/project”")

and replacing the simple \ by \ \ \ fixes the problem:
cppFlags.add("-DJUCE_ANDROID_ACTIVITY_CLASSPATH=\ \ "com/brand/project\ \ “”)

[EDIT: I had to add a space character between the \ to get it displayed properly here. Remove the space between the \ in build.gradle]

Don’t ask me why… I have no idea. But under Windows it looks like the \ which is escaping the " should be escaped itself.

Finally I created a batch file based on fart in order to update the build.gradle file after Projucer saving, here is the command line:

fart -C app\build.gradle \x5C\x22 \x5C\x5C\x5C\x22

But it would be great if Projucer could be fixed in order to generate the right build.gradle content.
