Problem schon bei Hallo Welt

Hallo Zusammen

Hoffe Jemand kann mir weiter helfen.
Habe mich vor nicht all zu Langer zeit begonnen, mich mit Android auseinander zu setzen.

Ich habe Eclipse(helios) mit dem Andoid plugin versehen und auch ein AVD
Name: my_test
Target:Android 2.2(API level 8 )
Skin: HVGA
SD Card: 250M

Nun habe ich das Hallo Welt mit der Ausgabe:
tv.setText("Hello, Android");
erstellt.

Wenn ich auf Run-> Run->Android Application Drücke, ladet er das Händy, aber nichts passiert.Folgende Meldungen kommen:

[2011-01-23 11:26:54 - hallowelt1] ------------------------------

So, vieleicht entdeckt jemand da schon den Fehler...
Auf jedenfall Passiert nichts auf dem Händy, wenn ich nun Entsperre kommt folgende Meldung:
The application ApiDemos
(process com.example.andoid.apis) has stopped unexpectedly.
Please try again.

Ich habe es mehrmals versucht, mit verschiedenen Projekten, immer das Gleiche....
Kann mir jemand weiter helfen, währe sehr dankbar.

Gruss Michelho

Was sagt denn die LogCat? Die Console bringt meistens nichts wenn ein Error auftritt. Öffne mal die LogCat via Window -> Show View -> Others -> Android -> LogCat. Dann startest du die App nochmal bis zum Error und dann postest du den Stacktrace der in der LogCat erscheint.
Die Warnung kriegst du übrigens weg, indem du im AndroidManifest.xml ein uses-sdk angibst (minSdkVersion, targetSdkVersion und maxSdkVersion).

Da haben wirs. Er findet deine Klasse nicht (Wobei es in dem Fall eher ne Demo-Klasse ist, wozu brauchst du das in einem Hallo Welt?!)
Noch ne Frage: Was sollen all die Permissions? oO Schmeiss die mal raus ausm Android Manifest.

Ich habe mir das buch: Android 2 Grundlagen und Programmierung gekauft, und habe dort ein Formular erstellt...
Als dort der Fehler kam, habe ich dieses "einfache Hallo Welt" programmiert... und es kam die selbe Fehlermeldung
Bei dem vom Buch bringt er:

sieht fast gleich aus.... was muss ich machen?

WIeder die gleiche Klasse die nicht gefunden wird. Hast du die ApiDemos Klasse irgendwo im Manifest oder benutzt du sie im Code? Ich kann nicht viel sagen ohne deinen Code zu sehen.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.apis"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".ApiDemos"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

</application>
<uses-sdk android:minSdkVersion="5" />

</manifest>
ja, es kommt vor

Heisst deine Activity denn auch ApiDemos? Wenn nein, dann ändere entweder den Namen der Activity in "ApiDemos" oder das Manifest.

Danke viel mahls Für deine Bemühungen... hateste recht, läuft nun
Danke viel mals
