Seltsamer Crash

[Liamissimo]

Hey,
sobald ich auch nur etwas Code einfüge crasht es. IMMER. Ich bin ein Neuling in Android/Java aber habe schon gute C Kenntnisse, nur treibt mich das an meine Gedulds-Grenzen. Toast, Vibrator oder auch nur ein Bildwechsel -> Crash beim Startup

package com.vibdroid;

import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.os.Vibrator;
import android.text.InputFilter.LengthFilter;
import android.view.View;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.Toast;

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    	final ImageButton andvib = (ImageButton)findViewById(R.id.vib_but);
        andvib.setOnClickListener(new View.OnClickListener() {			
			@Override
			public void onClick(View v) {
				Drawable ne = null;
				ne = getResources().getDrawable(R.drawable.icon);
			    andvib.setImageDrawable(ne);
			}
		});
    }
}

Habe sogar schon eine funktionierende andere App, Copy&Paste bringt auch nichts.

Schau mal in der zeile 21 nach, was genau du kastest
( Es hilft, logs durchzulesen - da steht es nämlich im Klartext drin )

Java ist nun mal so schlau, gleich zu bomben wenn du etwas falsches kastest -
und nicht wie C erst wenn der Pointer ins leere geht

Update: Wieder nur Crash, auch wenn ich allen Code gelöscht habe und nun steht nur der Standard-Projektstart Code drin und ein onClickListener, eine PNG Grafik und ein ImageView als Button. Logcat ist der selbe wie oben...
Ein Wechsel von SDK Target 4 (1.6) auf 2.1 hat es gelöst
Auch wenn ich nicht über den Logcat zeile 21 drauf gekommen bin, da steht nur er kann den MediaPlayer nicht starten.

 

[ko5tik]

Ich meinte nicht im Logcat, sondern in deiner onCreate() Methode von MainActivity

 

[Liamissimo]

Hm, was ist an dem Button und onClickListener falsch?

 

[ko5tik]

Das wahr wohl kein ImageButton, das aus der View-Hierarchie geladen wurde
