Hi guys,

i'm currently facing a weird problem in my app.

I'm trying to create Previews of my android Wear Watchface, so everybody can see how his settings will look like.
--screens attached--

However, the app crashes if i change the fragment...

This is my code to change the fragment:

Code: 
private void changeFragment(int index)
    {
        if(index != 7 && index != 0) {
            showAd();
        }
        FragmentTransaction ft = getFragmentManager().beginTransaction();
        switch (index) {
            case 0:
                WizardFrameHello fragment = new WizardFrameHello();
                fragment.setParentActivity(this);
                if (lastFragment != null)
                    ft.remove(lastFragment);
                ft.add(R.id.frameWizard, (Fragment) fragment);
                ft.commit();
                lastFragment = fragment;
                break;
            case 7:
                WizardFrameSelectProcedure fragment7 = new WizardFrameSelectProcedure();
                fragment7.setParentActivity(this);
                if (lastFragment != null)
                    ft.remove(lastFragment);
                ft.add(R.id.frameWizard, (Fragment) fragment7);
                ft.commit();
                lastFragment = fragment7;
                break;
            [...]
            case 11:
                WizardFrameLanguages fragment11 = new WizardFrameLanguages();
                fragment11.setParentActivity(this);
                if (lastFragment != null)
                    ft.remove(lastFragment);
                ft.add(R.id.frameWizard, (Fragment) fragment11);
                ft.commit();
                lastFragment = fragment11;
                break;

        }
    }
    public void prevStep() {
        if (index == 5 && textResource.USE_SPECIFIC) {
            index = 3;
            changeFragment(index);
        } else if (index == 4 || index == 3) {
            index = 2;
            changeFragment(index);
        } else if (index > 0) {
            index--;
            changeFragment(index);
        }
    }
    public void setStep(int step)
    {
        index = step;
        changeFragment(index);
    }
    public void nextStep() {
        if (index == 3)
            index = 4;
        if (index < maxindex) {
            index++;
            changeFragment(index);
        }
    }


These are the dumps i got:

i've already tried to get some info with android ndk-stack but no luck.
This is the output:

which is quite saying nothing to me. it should look more like this (example):

Can you help me ?
Getting the function thats causing the error would be great.

Thanks,

Maximilian

Solved

Well,

this bug was actually caused trough Gson.

I serialized a class containing the settings and a preview bitmap, which was then deserialized to display all available settings,
once the bitmaps were getting destroyed trough garbage collector, the whole system crashed.

I got this error on my tablet, which finally let me dig deeper in my bitmap usages:

I solved this, trough by adding transient to my bitmap:
Code: 
  public transient Bitmap preview;
However,
thanks for everyone who may have had a look into this.

Cheers,
Maximilian
