Answer 1

I solve my question . firstly you must hide your app icon by remove

 <category android:name="android.intent.category.LAUNCHER"

second you can add code in app B

 Intent intent = new Intent("com.example.hideicon");
              intent.setComponent(ComponentName
                  .unflattenFromString("com.example.hideicon/com.example.hideicon.MainActivity"));
              intent.addCategory("android.intent.category.LAUNCHER");
              startActivity(intent);

For hide app icon

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(Test.this,com.example.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

For display app icon

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(Test.this, com.example.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

Answer 3

It will not work since you have disabled the component and haven't enabled it before starting. To disable/enable it requires the permission.
