As the company's business expands, the size of the App has also been increasing. Significant effects have been achieved through the past several App optimization optimizations. Conventional methods are now insufficient to reduce the size of the App any further. After analyzing the App, we found that some resources that are not frequently used and can be delivered, so we designed this SDK for dynamic resource loading.

Features

  • There are 3 built-in resources of predefined fonts, frame animations, SO, and 2 customizable resources such as single file and multiple files.
  • Provides a common method for loading dynamic resources from which all resources can be loaded.
  • Built-in resources, providing default application methods, external can be applied directly. Custom resources, users decide how to apply.
  • For all resources, provide configurable packaging to reduce manual work.

The effect used in the project

By introducing a Dynamic Resource Management System, and dynamically packaging some .so files and other ordinary resources, the package size of the LalaMove client has been reduced from 54M to 46M, a decrease of 8M. Subsequent efforts will continue to explore ways of further dynamic packaging for other files.

Module Introduction

Module Function
sample_app Demo's app module
dynamic_res_plugin Plugin module
dynamic_res_base Base module
dynamic_res_core Core module
sample_native_lib Demo's native library example
dynamic_res_store Generated resource folder
dynamic_plugin.gradle Plugin script

Getting started

1.Compile and import plugin

  1. Add dependencies to the module

    classpath 'cn.huolala:dynamic_res_core:1.1.2'

  2. Add dynamic_res_plugin as a dependency in your main build.gradle in the root of your project

    classpath 'cn.huolala:dynamic_res_plugin:1.1.2'

  3. Then you need to "apply" the plugin and add dependencies by adding the following lines to your app/build.gradle.

    apply plugin: 'com.lalamove.dynamic_res_plugin'

2.Import config

Apply the plugin in your main build.gradle in the root of your project apply from: 'dynamic_plugin.gradle'

3.Generate Resources Package

  1. Generate native library package

    Add "dynamic_config" into dynamic_plugin.gradle learn more at the sample dynamic_plugin.gradle

  2. Generate other resources package

    Copy fonts, frame animations, and other resources to the path dynamic_res_store/input/

  3. build application

    The plugin will generate the resources in the dynamic_res_store/output/ directory.

  4. Upload resources

    Upload the resource to the server

  5. Generate resource url ,fill into DynamicResConst.java

4.Initialize

DynamicConfig config = DynamicConfig.Builder.with(context)
        .executor()
        .loadSoManager(createLoadSoManager())
        .downlader()
        .debugLog(BuildConfig.DEBUG)
        .loggger()
        .monitor()
        .build();
DynamicResManager.getInstance().init(config);

learn more at the sample "DynamicInitJob.java"

5.Preloading

IoThreadPool.getInstance().getThreadPoolExecutor().execute(() -> {
    if (DynamicResManager.getInstance().getLoadSoManager() != null) {
        DynamicResManager.getInstance().getLoadSoManager().loadSo(DynamicResConst.DEMO_SO, null);
    }
});

learn more at the sample PreDynamicLoadJob.java

6.Usage

  1. Font

    DynamicResManager.getInstance().setTypeface(mFontTv, DynamicResConst.TypeFace.FONT_FZ_RZ_BOLD);
    
  2. FrameAnimation

    mCarAnim = DynamicResManager.getInstance().createFrameAnim(ImageView).durations(100).oneShot(false);
    mCarAnim.startAnim(DynamicResConst.FrameAnim.ANIM_CAR);
    
  3. so

    DynamicResManager.getInstance().getLoadSoManager().loadSo(DynamicResConst.DEMO_SO, new ILoadSoListener() {
         @Override
         public void onSucceed(String path) {
             mContentTv.append(new NativeLib().stringFromJNI());
         }
    });
