Include Stetho only in the debug build variant

Question

I know that I can use debugCompile to only pull in a dependency for the debug build. Is there a good, streamlined way to do the

Answer 1

There is more cardinal method to connect stetho or any other lib only to debug builds - using reflection: 1) Connect your lib via debugImplementation - debugImplementation 'com.facebook.stetho:stetho:1.5.1' 2) Implement class with only static members - DynamicClassUtils:

public class DynamicClassUtils {
private static final String TAG = "DynamicClassUtils";

public static void safeInvokeStaticMethod(String fullClassName, String methodName, Class[] types, Object... args) {
    try {
        Class aClass = Class.forName(fullClassName);
        Method aMethod = aClass.getMethod(methodName, types);
        aMethod.invoke(null, args);
    } catch (Throwable e) {
        if (BuildConfig.DEBUG) {
            Log.e(TAG, "Error when invoking static method, message: " + e.getMessage() + ", class: " + e.getClass());
            e.printStackTrace();
        }
    }
}

public static  T safeGetInstance(String fullClassName, Object... args) {
    try {
        ArrayList> formalParameters = new ArrayList<>();
        for (Object arg : args) {
            formalParameters.add(arg.getClass());
        }
        Class aClass = Class.forName(fullClassName);
        Constructor ctor = aClass.getConstructor(formalParameters.toArray(new Class[0]));
        return (T) ctor.newInstance(args);
    } catch (Throwable e) {
        if (BuildConfig.DEBUG) {
            Log.e(TAG, "Error when creating instance, message: " + e.getMessage());
            e.printStackTrace();
        }
        return null;
    }
}

3) use that class to init stetho and its network interceptor:

        if (BuildConfig.DEBUG) {
        Class[] argTypes = new Class[1];
        argTypes[0] = Context.class;
        DynamicClassUtils.safeInvokeStaticMethod("com.facebook.stetho.Stetho", "initializeWithDefaults", argTypes, this);
    }

        if (BuildConfig.DEBUG) {
        Interceptor interceptor = DynamicClassUtils.safeGetInstance("com.facebook.stetho.okhttp3.StethoInterceptor");
        if (interceptor != null) client.addNetworkInterceptor(interceptor);
    }
