I want to make my app ready for instant apps. I have created an app module, base module and a feature module. if I run my project in this configuration everything works great.
when i implement the following lines inside my base module Gradle file.
annotationProcessor "android.arch.lifecycle:compiler:1.0.0"
api "android.arch.lifecycle:extensions:1.0.0"
the Gradle build succeeds but I lose my default activity and can't run the project. the default activity is inside my base module manifest.
if i change the extensions line with implementation.
implementation "android.arch.lifecycle:extensions:1.0.0"
the following error happens:
Error:Execution failed for task ':app:preDebugBuild'.
Android dependency 'android.arch.lifecycle:runtime' has different version for the compile (1.0.0) and runtime (1.0.3) classpath. You should manually set the same version via DependencyResolution
does anyone knows what the problem can be?
When using the support lib 26.1.0 or higher the lifecycle functionality is included inside. by removing the following lib lines
annotationProcessor "android.arch.lifecycle:compiler:1.0.0"
api "android.arch.lifecycle:extensions:1.0.0"
and only using the :
implementation 'com.android.support:appcompat-v7:26.1.0'
everything was working again.
