Hallo ich wollte fragen ob jemand vieleicht weis wo mein Fehler liegt dass beim starten einens Test Programmes mit einem TabHost die Applikation immer abstürzt. Im Code wird mir kein Fehler angezeigt. Ich benutzte die Android 2.0.1 Emulator Version. Hier mein Code:
Tab.java Datei:
main.xml Datei
Androidmanifest Datei
FirstTab.java
SecondTab.java
Ich hoffe ihr könnt mir weiter helfen.

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/** TabHost will have Tabs */
TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
/** TabSpec used to create a new tab.
* By using TabSpec only we can able to setContent to the tab.
* By using TabSpec setIndicator() we can set name to tab. */
/** tid1 is firstTabSpec Id. Its used to access outside. */
TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
TabSpec secondTabSpec = tabHost.newTabSpec("tid1");
/** TabSpec setIndicator() is used to set name for the tab. */
