Build issue on Windows for Android app


#1

Hi, getting the following error:
Error:A problem occurred configuring project ‘:app’.

executing external native build for cmake C:\Users\leehu\Development\cpp\JUCE\Projects\xxx\Builds\Android\app\CMakeLists.txt

Not sure how to proceed - same Projucer file works fine on OSX.

thx


#2

You need to post the full gradle log. Usually there is a line (pretty hidden) about the reason why cmake failed - usually because it couldn’t find a file or library you are referring to.


#3

got ya - sorry, stlll finding my way round Anroid Studio

yes, missing library… actually, related to

as I can’t find a way to automatically copy Android libraries to a destination… Is there a way to do this? thx


#4

Hi, I’ve copied the missing library manually and still no joy. This is the gradle output:

Executing tasks: [:app:generateDebug_DebugSources, :app:prepareDebug_DebugUnitTestDependencies, :app:mockableAndroidJar, :app:generateDebug_DebugAndroidTestSources, :app:compileDebug_DebugSources, :app:compileDebug_DebugUnitTestSources, :app:compileDebug_DebugAndroidTestSources]

Configuration on demand is an incubating feature.

We do this regularly at ROLI so it should definitely work.Obviously, it’s having trouble to find midisynthlib. In the projucer, are you sure the you have specified the “Extra Library Search Paths” correctly?


#6

In case you need help troubleshooting where it is trying to load the library from, I recommend using Process Monitor from the SysInternals tools (https://docs.microsoft.com/en-us/sysinternals/downloads/procmon). You can filter the file system activity by the library name, and see where the linker is actual trying to load the library from. This has helped me understand issues like these many times.


#7

Hi fabian. This is my search path:

~/Development/cpp/JUCE/lib/android/debug

This works on OSX and there’s only 1 config for Android, so OSX is using the same settings


#8

Hi @leehu,

Does the tilde ~ work on Windows? I don’t think the Android build environment is executed in a UNIX-type shell. Can you try replacing the path with the absolute path. In any case, the Projucer should take care of replacing the ~ character if it isn’t supported. I’ll have a look.

#9

Still the same - going to try and manually configure AS to try and pick this library up…


#10

sorry, that did work - it needs to have the full patch including drive letter

Not sure where the ~ replacement should be happening, but the generated cmake file still contains the ~ if the substitution should have been done by this point…

thx


#11

For release it appears as though I need to create a new configuration for each architecture so I can specify the correct path to pick the library up from. This is fine, but not sure then how to go about creating a single APK for the Google store that contains all of the architectures…

#13

You can use ${ANDROID_ABI} in the library search paths. For example this is what we do in NOISE:
