11 How are the SDKs integrated into my Application? PART TWO

Slide 66

Slide 66 text

App integration 64 Single framework that can be added to your application Single or service level jars available Android iOS

Slide 67

Slide 67 text

App integration 65 Single framework that can be added to your application Single or service level jars available Statically linked (only parts that are used will be added) Proguard integration (obfuscate/minimize) Android iOS

Slide 68

Slide 68 text

Why Proguard is important 1) Removes unused code (usage.txt) 2) Classes/fields/methods names are obscured (mapping.txt) 3) Non obfuscated ones are listed in “seeds.txt” 4) The resulting .apk is smaller, harder to reverse engineer 66
