Question

I am getting this very weird error when trying to run my application. Due to my tabs I think. Here is the error:

Here is my xml file:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:background="#ccc" >

        <TextView
            android:id="@+id/titleTV"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="5dp"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="5dp"
            android:text="Bytes"
            android:textSize="20dp" />
    </LinearLayout>

    <TabHost

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical" >

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" >
            </TabWidget>

            <FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="match_parent"
                android:layout_height="match_parent" >

                <LinearLayout
                    android:id="@+id/tab1"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" >
                </LinearLayout>

                <LinearLayout
                    android:id="@+id/tab2"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" >
                </LinearLayout>

                <LinearLayout
                    android:id="@+id/tab3"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" >
                </LinearLayout>
            </FrameLayout>
        </LinearLayout>
    </TabHost>

</RelativeLayout>

And my OnCreate method:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

tabHost = (TabHost)findViewById(android.R.id.tabhost);
tabHost.setup();

TabSpec ts = tabHost.newTabSpec("Home").setIndicator("Home").setContent(new Intent().setClass(this,MainActivity.class));
tabHost.addTab(ts);
ts = tabHost.newTabSpec("Quests").setIndicator("Quests").setContent(new Intent().setClass(this,Jobs.class));
tabHost.addTab(ts);

tabHost.setCurrentTab(0);

I have never seen this error before. For some reason my xml file is having issues inflating?

Answer 1

You are creating an infinite loop by trying to load:
MainActivity _{with MainActivity in a tab, with MainActivity in a tab, with MainActivity in a tab, with MainActivity in a tab, with MainActivity in a tab, with MainActivity in a tab, with MainActivity in a tab, with MainActivity in a tab, with MainActivity in a tab,}

This is the troublesome line:

TabSpec ts = tabHost.newTabSpec("Home").setIndicator("Home").setContent(new Intent().setClass(this,MainActivity.class));

I have the feeling your full LogCat shows the root cause is a StackOverflowException…

Anyway you need to make a new class, call it “Home”, where MainActivity loads the tabs and Home is your default screen.
