Putting All Together

1. Initialization in Activity

You could use DebugDrawer or DebugView depending on your needs

Example using DebugDrawer (For DebugView initialization check DebugViewActivity)

    private DebugDrawer debugDrawer;

    protected void onCreate(Bundle savedInstanceState) {

        SwitchAction switchAction = new SwitchAction("Test switch", new SwitchAction.Listener() {
            public void onCheckedChanged(boolean value) {
                Toast.makeText(MainActivity.this, "Switch checked", Toast.LENGTH_LONG).show();

        ButtonAction buttonAction = new ButtonAction("Test button", new ButtonAction.Listener() {
            public void onClick() {
                Toast.makeText(MainActivity.this, "Button clicked", Toast.LENGTH_LONG).show();

        SpinnerAction<String> spinnerAction = new SpinnerAction<>(
            Arrays.asList("First", "Second", "Third"),
            new SpinnerAction.OnItemSelectedListener<String>() {
                @Override public void onItemSelected(String value) {
                    Toast.makeText(MainActivity.this, "Spinner item selected - " + value, Toast.LENGTH_LONG).show();

        debugDrawer = new DebugDrawer.Builder(this)
                new ActionsModule(switchAction, buttonAction, spinnerAction),
                new FpsModule(Takt.stock(getApplication())),
                new LocationModule(this),
                new ScalpelModule(this),
                new TimberModule(),
                new OkHttp3Module(okHttpClient),
                new PicassoModule(picasso),
                new GlideModule(Glide.get(getContext())),
                new DeviceModule(this),
                new BuildModule(this),
                new NetworkModule(this),
                new SettingsModule(this)

2. TimberModule

Don't forget to plant needed log trees in Application class. Tree that is used by TimberModule stored in LumberYard class.

Application class example:

    public class DebugDrawerApplication extends Application {
        public void onCreate() {

            LumberYard lumberYard = LumberYard.getInstance(this);

            Timber.plant(new Timber.DebugTree());

Creating and Publishing Your Own Module

Add implementation 'io.palaima.debugdrawer:debugdrawer-base:0.8.0' to your dependencies

Module must implement DebugModule interface or extend DebugModuleAdapter if you do not need lifecycle hooks

    public interface DebugModule {

         * Creates module view
        @NonNull View onCreateView(@NonNull LayoutInflater inflater, @NonNull ViewGroup parent);

         * Override this method if you need to refresh
         * some information  when drawer is opened
        void onOpened();

         * Override this method if you need to stop
         * some actions  when drawer is closed
        void onClosed();

         * Override this method if you need to start
         * some processes
        void onResume();

         * Override this method if you need to do
         * some clean up
        void onPause();

         * Override this method if you need to start
         * some processes that would be killed when
         * onStop() is called
         * E.g. register receivers
        void onStart();

         * Override this method if you need to do
         * some clean up when activity goes to foreground.
         * E.g. unregister receivers
        void onStop();


You can clone the project and compile it yourself (it includes a sample).
