Issue / Feature - Issue FolioReader version - 0.5.4 FolioReader Stock / Modified - Stock Android SDK - 28 Mobile / Tablet / Emulator Info - Mobile Crash / Error - Crash

This is how I have declared Folio reader in my AndoridManifest.xml file.

<activity android:name="com.folioreader.ui.folio.activity.FolioActivity" android:configChanges="orientation|screenSize" android:label="@string/app_name" android:theme="@style/AppTheme.NoActionBar" />

But my Android studio shows a red sign over folio saying, Class referenced in the manifest, com.folioreader.ui.folio.activity.FolioActivity, was not found in the project or the libraries Unresolved class 'FolioActivity'

This is how I call Folio Reader :

                 ```
   if (sdIconStorageDir.toString() != null) {
                        FolioReader folioReader = FolioReader.get();
                        folioReader.setOnHighlightListener(new OnHighlightListener() {
                            @Override
                            public void onHighlight(HighLight highlight, HighLight.HighLightAction type) {
                            }
                        });
                        folioReader.openBook(sdIconStorageDir.toString());
                    }else{
                        Toast.makeText(activity,"This Book not available",Toast.LENGTH_SHORT).show();
                    }
                } catch (Exception e) {
                    Log.e("Exception-down", "" + e.getMessage());
                }
            }
        }
    }

hey @yashdevelops --- try adding proguard rule for event bus or disabling it

[yashdevelops]

@PoyyamozhiRamakrishnan Do you have any references from where I can learn or get it ? thank you.

[PoyyamozhiRamakrishnan]

@yashdevelops https://github.com/greenrobot/EventBus#r8-proguard, add these proguard rules to your proguard-rules.pro file or change minifyEnabled true to minifyEnabled false in your app build gradle file
