Usage

Step 1.Add initialized code in the Application

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        try {
            BlackBoxCore.get().doAttachBaseContext(base, new ClientConfiguration() {
                @Override
                public String getHostPackageName() {
                    return base.getPackageName();
                }
            });
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onCreate() {
        super.onCreate();
        BlackBoxCore.get().doCreate();
    }

Step 2.Install application

    // Use package name to install provided that application has been install on device
    BlackBoxCore.get().installPackageAsUser("com.tencent.mm", userId);
    
    // Use APK path to install provided that application has not been install on device
    BlackBoxCore.get().installPackageAsUser(new File("/sdcard/com.tencent.mm.apk"), userId);

Step 3.Launch application

   BlackBoxCore.get().launchApk("com.tencent.mm", userId);

App Cloner

Fake Location

Fake location base theory: forbid WPS(Wi-Fi Positioning System) and LBS(MPS), only provide modified GPS location server.

Fake Device Info

Modify device info in source code, ui isn't available

• Xiaomi device tested successfully.
• Huawei device tested failed, it need to be enhanced.

API

Get application list that were installed in BlackBox

   // flags can refer to the Android develop documentation
   BlackBoxCore.get().getInstalledApplications(flags, userId);
   
   BlackBoxCore.get().getInstalledPackages(flags, userId);

Get user information in BlackBox

   List<BUserInfo> users = BlackBoxCore.get().getUsers();

If you want to perform more operations, please refer to the source code.
