How to spot app freeze causes when app is returning from pause state?

Question

My App is facing a really weird behavior:

App is started normally;
I leave the app for another one or back to the phone's home screen;
When I try to go back to the previous app instance, it hangs until I get the "App is not responding, force it to close?";

I know it sounds like some memory leak or loop stuck problem, but this behavior is complety random (sometimes I perform the steps above twice and I get the problem, other times I do it like ten times until I get the error). No Exception is thrown in the logcat. In the Monitor, alocated memory never explodes and it keeps below the free memory. I've used the memory analizer and nothing weird is shown in report.

I've noticed already that when I use loader spinners in my Activity, the number of times needed performing the steps above in order for the App to crash decreases - sometimes doing them once makes the app crash.

Does anyone have a suggestion of what can I do in order to figure out what might be causing this problem?

Thank you.

EDIT

This behavior can happen in any of the App's activities, Logcat and code can be foundbelow:

All my activities are descendant of this template:

public abstract class ActivityTemplate extends AppCompatActivity {

    private Boolean isRunning = Boolean.TRUE;

    private ToolbarManager mToolbarManager;
    private ActivitySetup mSetup;

    public abstract ActivitySetup setUpActivity();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mToolbarManager = new ToolbarManager();
        mSetup = setUpActivity();
        setContentView(mSetup.getContentView());
        ButterKnife.bind(this);
        prepareToolbar();
        registerForEvents();
        this.startResources();
    }

    private void prepareToolbar() {
        if (mSetup.getHasToolbar()) {
            mToolbarManager.initToolbar(this, mSetup.getTitle(), R.id.toolbar, R.color.textPrimary);
            if (mSetup.getDefaultReturnBehavior()) {
                mToolbarManager.setNavigationReturnBehavior();
            }
            mToolbarManager.prepareNavigationBehavior(mSetup.getNavigationIcon(), mSetup.getOnNavigationItemClicked());
        }
    }

    public void startResources() {
    }

    @Override
    public void onDestroy() {
        this.unregisterForEvents();
        super.onDestroy();
    }

    @Override
    protected void onPause() {
        super.onPause();
        this.isRunning = Boolean.FALSE;
    }

    @Override
    protected void onResume() {
        super.onResume();
        this.isRunning = Boolean.TRUE;
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        return super.onCreateOptionsMenu(menu);
    }

    public void registerForEvents() {
        Map<EventCatalog, TaskExecutor> executors = this.setEventHandlers();
        if (null != executors && executors.size() > 0) {
            for (EventCatalog event : executors.keySet()) {
                NotificationCenter.RegistrationCenter.registerForEvent(event, executors.get(event));
            }
        }
    }

    public void unregisterForEvents() {
        Map<EventCatalog, TaskExecutor> executors = this.setEventHandlers();
        if (null != executors && executors.size() > 0) {
            for (EventCatalog key : executors.keySet()) {
                NotificationCenter.RegistrationCenter.unregisterForEvent(key, executors.get(key));
            }
        }
    }

    public boolean isRunning() {
        return this.isRunning;
    }

    public Toolbar getToolbar() {
        return mToolbarManager.getToolbar();
    }

    public Map<EventCatalog, TaskExecutor> setEventHandlers() {
        return null;
    }
}

EDIT 2

It looks like this issue is related with the use of Firebase and Google Services, however, I need both in my App. The way I'm using them is:

On top gradle file: classpath 'com.google.gms:google-services:3.0.0'

On my App gradle file:

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    dexOptions {
        javaMaxHeapSize "4g"
    }

    defaultConfig {
        applicationId "br.com.gogame"
        minSdkVersion 21
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }

    buildTypes {

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

question is off-topic: *Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself.* ... so you will get off-topic answer: stop messing with StrictMode and catch networkonmainthread exception ... or check twice if both: obtaining data from internet and parsing are done on non UI thread ... also use lists with recycler patterns (like RecyclerView, ListView, etc) and use it right — Selvin, Jun 13 '16 at 13:40

The way I'm importing google services is like that: I have this in the top gradle file classpath 'com.google.gms:google-services:3.0.0', and in my app module I have apply plugin: 'com.google.gms.google-services'. I can't reproduce the answer :/ — E. Fernandes, Jun 13 '16 at 14:25

Ok, so following @ApplicationDeveloper tip, I've removed compile 'com.google.android.gms:play-services:9.0.0' from my project, it wasn't in my main project, it was in a library module. It has solved the question.
