This slide explains a simple Android library called Debot. Debot offers features that are useful to debug Android applications. Those features can be added to any activity that has the toolbar menu. Also, developers can easily add their own custom debugging features with simple steps. https://github.com/tomoima525/debot

3. Debugging in Android

4. Things developers do for debugging
• Visualise an apps data
• Activity, intent, logs etc.
• Visualise ( numerous kinds of )devices’ data
• Screen density, OS ver, memory etc.
• Check the behaviour of apps

5. What bothers developers
when debugging?

6. Unnecessary code for Production
…but you need them for debugging :-(

7. Wasting time reproducing same behaviour
• Input texts
• Change settings
• Access Api

8. Way to check app & device info are limited
• Check from Setting
• Write some codes ( but you need them rarely )

9. Tired of wasting your time
debugging?

10. Debot
A simple Android Library to support
your debugging

11. Debot offers you productive debugging
features
1. Has useful debugging features by default
2. Hassle-free implementation
3. Customisable Plugins
4. Able to call specific methods from Activity

12. 1. Debugging features

13. Debugging features
• Default Debugging menu
• check dpi
• show intent
• check App ver
• dev input

14. Debugging features
• Visualise app and device info

15. Debugging features
• Auto Input
@DebotAnnotation("debugInput")
public void debugInput() {
EditText editText
= (EditText) findViewById(R.id.input_1);
editText.setText("This is sample!");
}

16. 2. Hassle-free Implementation

17. Implementation
dependencies {
compileDebug 'com.tomoima.debot:debot:1.0.1'
compileRelease ‘com.tomoima.debot:debot-no-op:1.0.1’
}
build.gradle

18. Implementation
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
DebotConfigurator.configureWithDefault(this);
}
}
Application.java

19. Implementation
public class MainActivity extends AppCompatActivity{
@Override
public boolean onCreateOptionsMenu(Menu menu) {
Debot.onCreateOptionsMenu(menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
Debot.onOptionsItemSelected(item);
return super.onOptionsItemSelected(item);
}
@Override
protected void onResume() {
super.onResume();
Debot.onResume(this);
}
@Override
protected void onPause() {
super.onPause();
Debot.onPause(this);
}
}

20. 3. Customisable Plugins

21. Customisable Plugins
public class MyDebotStrategy extends DebotStrategy{
@Override
public void startAction(@NonNull Activity activity) {
// Do your things
}
}

22. Customisable Plugins
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
DebotStrategyBuilder builder
= new DebotStrategyBuilder.Builder(context)
.registerMenu("My feature", new MyDebotStrategy())
.build();
DebotConfigurator.
configureWithCustomizeMenu(this, builder.getStrategyList());
}
}

23. 4. Call methods from Activity

24. Call methods from Activity
@DebotAnnotation(“callApiForDebug")
public void callApiForDebug() {
Api.call(this, params);
}
@DebotAnnotation(“startActivityForDebug")
public void startActivityForDebug() {
Intent intent = NextActivity.createIntent(this, params);
startActivity(intent);
}
MyActivity.java

25. Call methods from Activity
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
DebotStrategyBuilder builder =
new DebotStrategyBuilder.Builder(context)
.registerMenu(“call api",
new DebotCallActivityMethodStrategy(“callApiForDebug”))
.registerMenu(“start activity",
new DebotCallActivityMethodStrategy(“startActivityForDebug"))
.build();
DebotConfigurator
.configureWithCustomizeMenu(this, builder.getStrategyList());
}
}

26. Happy debugging with Debot!
