How to reduce the size of the application?

Question

In my Application i use 54 images.in order to support multiple screen i create folders like this

drawable-hdpi
drawable-mdpi
drawable-xdpi
drawable-mdpi

and paste all the images in each of the folder.due to this the application size is increased a lot.... then i try to like this way... take only one folder drawable keep all 54 images in that delete all your drawabl-mdpi,drawable-hdpi,drawable-mdpi and drawable-xdpi folders . In my Manifest file i mensioned as

"<supports-screens 
android:anyDensity="true" 
android:largeScreens="true" 
android:normalScreens="true" 
android:resizeable="true" 
android:smallScreens="true" />"

but it give me errors like this

There are main four errors in your application

java.lang.RuntimeException: Unable to start activity 
   **ComponentInfo{com.jacksonville.alenseventapp/com.
   jacksonville.alenseventapp.HomeActivity}:

and

** android.view.InflateException: Binary XML file line #1:
       Error inflating class <unknown>
       07-25 15:04:25.967: ERROR/AndroidRuntime(13963):    
       at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) 
        and 07-25 15:04:25.967: ERROR/AndroidRuntime(13963): Caused by: 
        android.view.InflateException: Binary XML file line #1: 
        Error inflating class <unknown>

These two errors suggest that you are referring to a package which does not exist this might be due to the tutorial you followed to do this code , you used package name of that code in you application

and third error

    07-25 15:04:25.967: ERROR/AndroidRuntime(13963): Caused by: 
java.lang.reflect.InvocationTargetException

see these questions also had the same issue

How to remove this error ? java.lang.reflect.InvocationTargetException

InvocationTargetException on inflating an xml - android

and also see this

http://developer.android.com/reference/java/lang/reflect/InvocationTargetException.html

and it is caused by being low on memory

Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget

to avoid this you can use this method to display

// here path is from  where you are picking the image 



Bitmap myBitmap = ShrinkBitmap(Path, 300, 300);

MyImageView.setImageBitmap(myBitmap );


private Bitmap ShrinkBitmap(String file, int width, int height) {
        // TODO Auto-generated method stub
        BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
        bmpFactoryOptions.inJustDecodeBounds = true;
        Bitmap bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);

        int heightRatio = (int)Math.ceil(bmpFactoryOptions.outHeight/(float)height);
        int widthRatio = (int)Math.ceil(bmpFactoryOptions.outWidth/(float)width);

        if (heightRatio > 1 || widthRatio > 1)
        {
         if (heightRatio > widthRatio)
         {
          bmpFactoryOptions.inSampleSize = heightRatio;
         } else {
          bmpFactoryOptions.inSampleSize = widthRatio;
         }
        }

        bmpFactoryOptions.inJustDecodeBounds = false;
        bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
     return bitmap;
    }

drawable-hdpi drawable-mdpi drawable-xdpi drawable-mdpi if i follow this approach i donot get any error but the problem is the apk size is near to 8mb — Venkat, Jul 26 '12 at 06:56
" the problem is the apk size is near to 8mb " what is the problem int this — Avi Kumar, Jul 26 '12 at 06:59
