App crashing Android

Question

Anyone got any Idea why this code is not working, It was working fine until I tried to install the Google AdMob Ads SDK then all of a sudden the app crashes every time it I try and run it.

package co.miniz.RageToonViewer;

import java.io.FileReader;
import java.net.MalformedURLException;
import java.net.URL;
import org.w3c.dom.Text;
import co.miniz.RageToonViewer.R;
import co.miniz.RageToonViewer.ImageNumbers;
import co.miniz.RageToonViewer.NoRepeatRandom;
import co.miniz.RageToonViewer.Download;
import android.app.Activity;
import android.content.res.AssetManager;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;
import android.widget.Gallery;
import android.widget.ImageView;
import android.widget.TextView;

public class RageToonViewerActivity extends Activity {
FileReader reader;
URL url;
Download DL;
NoRepeatRandom randGen;
ImageNumbers noOfImages;
ImageView imView;
Gallery g;
Text text1;
Bitmap bmImg;
TextView tv;
AssetManager assetManager;
int random;
int prevRand = -10;
int noOfFiles ;


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
        assetManager = getAssets();
        DL = new Download();
        imView = (ImageView)findViewById(R.id.mainImage);
        imView.setScaleType(ImageView.ScaleType.FIT_CENTER);

        //----- Get Number OF Images -----
        noOfImages = new ImageNumbers();
        noOfFiles = noOfImages.GetNumber();

        //----- Set Button and Text outPut for testing -----
        Button button1main = (Button) findViewById(R.id.button1);
        tv = (TextView)findViewById(R.id.text1);
        tv.setText("Click above for a random RageToon!");


        //----- Generate Random Number -----
        randGen = new NoRepeatRandom(0, noOfFiles);
        random = randGen.GetRandom();

        //----- Set First Image -----
        imView.setImageBitmap(GetImage());

        //----- Set up Button Click Action -----
        button1main.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                tv.setText("Click above for a random RageToon!" + noOfFiles);
                noOfFiles = noOfImages.GetNumber();
                imView.setImageBitmap(GetImage());
            }
         });

        imView.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                tv.setText("Click above for a random RageToon!" + noOfFiles);
                noOfFiles = noOfImages.GetNumber();
                imView.setImageBitmap(GetImage());
            }
        });
} 

public Bitmap GetImage() {

    random = randGen.GetRandom();
    URL tempURL = null;
    try {
        tempURL = new URL("http://miniz.co/RageToonApp/Images/" + random + ".jpg");
    } catch (MalformedURLException e1) {
        e1.printStackTrace();
    }
    Bitmap TempImage = DL.getRemoteImage(tempURL, tv);

    if (TempImage == null)
    {
        TempImage = GetImage();
    }
   return TempImage;
}
}

When Debugging I can see an java.lang.RuntimeException: Unable to instantiate activity ComponentInfo in the LogCat view.

Thanks for any Help. Ross.

Edit: Thanks for the reply but the code is still not working after fixing the path names and such. I have found out that every app I now create in eclipse that uses any for of connection to the internet will now crash when I try and run it on my phone?
They also crash when I use the code:

requestWindowFeature(Window.FEATURE_NO_TITLE);

I hope this will help in determining what has gone wrong.

Answer 1

From exception it is clear that dalvik is looking your file "RageToonViewerActivity" under path "co.miniz.RageToon.RageToonViewerActivity" but is defined in package "package co.miniz.RageToonViewer" hence not able to locate.

1. I would advice you to go to android manifest file and where you activity is defined,give full path.

    <activity android:name="co.miniz.RageToonViewer.RageToonViewerActivity" // change this line android:screenOrientation="portrait"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>

2.Clean your Project. and have a go!!

Gud luck!!

Answer 2

mind this description: java.lang.ClassNotFoundException: co.miniz.RageToon.RageToonViewerActivity in loader dalvik.system.PathClassLoader

check your classpath.

Answer 3

I had the same problem when I used: requestWindowFeature(Window.FEATURE_NO_TITLE);

Now I used the code below and get no crashes.

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
