一、启动应用源码分析

---

1、HomeActivity 启动应用点击方法

在 io.virtualapp.home.HomeActivity 页面中 , 点击列表中的应用后 , 可以启动应用 ;

直接到 io.virtualapp.home.adapters.LaunchpadAdapter 适配器中查找点击事件源码 , 调用的是 private OnAppClickListener mAppClickListener; 成员变量的 onAppClick 方法 ;

该成员变量是通过 public void setAppClickListener(OnAppClickListener mAppClickListener) 方法注入的 ;

public class LaunchpadAdapter extends RecyclerView.Adapter<LaunchpadAdapter.ViewHolder> {

    private LayoutInflater mInflater;
    private List<AppData> mList;
    private SparseIntArray mColorArray = new SparseIntArray();
    private OnAppClickListener mAppClickListener;

    public void setAppClickListener(OnAppClickListener mAppClickListener) {
        this.mAppClickListener = mAppClickListener;
    }
    
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        holder.itemView.setBackgroundColor(holder.color);
        holder.itemView.setOnClickListener(v -> {
            if (mAppClickListener != null) {
                mAppClickListener.onAppClick(position, data);
            }
        });
    }
}

2、HomePresenterImpl 启动应用方法

调用 LaunchpadAdapter.setAppClickListener 方法注入应用启动点击事件 ,

public class HomeActivity extends VActivity implements HomeContract.HomeView {

    private static final String TAG = HomeActivity.class.getSimpleName();

    private HomeContract.HomePresenter mPresenter;
    private LaunchpadAdapter mLaunchpadAdapter;

    private void initLaunchpad() {
        mLaunchpadAdapter.setAppClickListener((pos, data) -> {
            if (!data.isLoading()) {
                if (data instanceof AddAppButton) {
                    onAddAppButtonClick();
                }
                mLaunchpadAdapter.notifyItemChanged(pos);
                mPresenter.launchApp(data);
            }
        });
    }
}

应用启动 , 实际上调用的是 io.virtualapp.home.HomePresenterImpl 的 public void launchApp(AppData data) 方法 ;

class HomePresenterImpl implements HomeContract.HomePresenter {

    @Override
    public void launchApp(AppData data) {
        try {
            if (data instanceof PackageAppData) {
                PackageAppData appData = (PackageAppData) data;
                Log.i("HSL", "PackageAppData : " + appData.toString());
                appData.isFirstOpen = false;
                LoadingActivity.launch(mActivity, appData.packageName, 0);
            } else if (data instanceof MultiplePackageAppData) {
                MultiplePackageAppData multipleData = (MultiplePackageAppData) data;
                Log.i("HSL", "MultiplePackageAppData : " + multipleData.toString());
                multipleData.isFirstOpen = false;
                LoadingActivity.launch(mActivity, multipleData.appInfo.packageName, ((MultiplePackageAppData) data).userId);
            }
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }
}

拦截一下数据 , 上述两个位置打印出来的日志如下 :

I/HSL: PackageAppData : PackageAppData{packageName='kim.hsl.svg', name='SVG', icon=android.graphics.drawable.BitmapDrawable@8d312bf, fastOpen=false, isFirstOpen=false, isLoading=false}

3、VirtualCore 启动插件应用最终方法

最终启动应用的方法是 io.virtualapp.home.LoadingActivity 类中的 public static void launch(Context context, String packageName, int userId) 方法 ;

先从 VirtualCore 中获取启动的 Intent 1 , 然后启动一个 VActivity , 创建 intent 2 , 将 从 VirtualCore 中获取启动的 Intent 放到 intent 2 中 ;

public class LoadingActivity extends VActivity {

    private static final String PKG_NAME_ARGUMENT = "MODEL_ARGUMENT";
    private static final String KEY_INTENT = "KEY_INTENT";
    private static final String KEY_USER = "KEY_USER";
    private PackageAppData appModel;

    public static void launch(Context context, String packageName, int userId) {
        Intent intent = VirtualCore.get().getLaunchIntent(packageName, userId);
        Log.i("HSL", "packageName : " + packageName + " , userId : " + userId);
        if (intent != null) {
            Intent loadingPageIntent = new Intent(context, LoadingActivity.class);
            loadingPageIntent.putExtra(PKG_NAME_ARGUMENT, packageName);
            loadingPageIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            loadingPageIntent.putExtra(KEY_INTENT, intent);
            loadingPageIntent.putExtra(KEY_USER, userId);
            context.startActivity(loadingPageIntent);
        }
    }
}

打印的数据 :

I/HSL: packageName : kim.hsl.svg , userId : 0
