Android : Need help in integrating lcp-client into readium library.

[nareshsvn]

Hi,

Android issue:
I am new to lcp . When I integrated lcp-client into readium library i am facing following issue.

issue description: Plugin with id 'com.android.model.library' not found. (build.gradle which is there in lcp-client module).

Steps I followed for the lcp integration into readium-1:

1. I cloned the code using "git clone --recursive https://github.com/readium/SDKLauncher-Android.git"

2. I opened this code from android studio and from android studio I shifted to "feature/lcp" branch from "master" branch.

3. Here I found a readium-lcp-client folder which is empty.

4. I downloaded readium-lcp-client code from github and I put that code into readium-lcp-client folder(step 3).

5. I tapped on sync button. Then I can see the above mentioned error.

Could please help me what went wrong in integration ?

Many Thanks,
Naresh

After step (1) you forgot to initialize the Git submodules:
cd SDKLauncher-Android && git submodule update --init --recursive

[danielweck]

Then, use the branch feature/latest-working-build-config for your cloned SDKLauncher-Android Git repository, and follow the advice in this Pull Request:
readium/SDKLauncher-Android#147

Same for readium-sdk (pay attention to the Java versions):
readium/readium-sdk#317

Same for readium-lcp-client:
#49

I hope this helps you. It did help me :)

4. Added local.properties files for SDK-Launcher , readium-sdk, redium-lcp-client. (Android / Gradle updates (current working build) SDKLauncher-Android#147, Various Android / Gradle updates (current working build) readium-sdk#317, Android / Gradle updates (current working build) #49). I am using java"1.8.0_191".

5. I downloaded readium-lcp-client code from github and I put that code into readium-lcp-client folder, I run following commands under SDKLauncher-Android\readium-lcp-client-master\platform\android
