Modify your Activity to override onSaveInstanceState and your onCreate method to restore from a "savedInstanceState".

public static final String TAB_STATE = "TAB_STATE";

@Override
protected void onSaveInstanceState(Bundle outState) {
    outstate.putParcelable(TAB_STATE, mTabHost.onSaveInstanceState());
    super.onSaveInstanceState(outState);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fag_tab_host_main);

    mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
    if(savedInstanceState==null || savedInstanceState.getParcelable(TAB_STATE)==null){
    mTabHost.addTab(mTabHost.newTabSpec("audio").setIndicator("Audio"),
            AudioContainerFragmentClass.class, null);
    mTabHost.addTab(mTabHost.newTabSpec("video").setIndicator("Video"),
            VideoContainerFragmentClass.class, null);
    } else{
        mTabHost.onRestoreInstanceState(savedInstanceState.getParcelable(TAB_STATE));
    }

}
