Does resource id changes everytime an application starts

Question

I am storing my images in drawable and their resource id in SQLite database.My database is created when the application starts for the first time.

Is it good to save the image ids in database or does the id's change every time an application start?

if id's change then while fetching back image id's I may receive an error.So,is storing image ID in database a good idea?

i need the images path to be stored in database with other relative data that's why i am storing the image id's in data base.

One approach would be storing the drawables in strings.xml as a string array something like this:

 <string-array name="location_flags">
    <item>@drawable/ic_image_name</item>
    <item>@drawable/ic_image_name</item>
    <item>@drawable/ic_image_name</item>
    <item>@drawable/ic_image_name</item>
    <item>@drawable/ic_image_name</item>
    <item>@drawable/ic_image_name</item>
    <item>@drawable/ic_image_name</item>
</string-array>

Then reading this array in your activity code :

TypedArray locationFlags=getResources().obtainTypedArray(R.array.location_flags);

Then applying the for loop you can get the Drawable something like this:

for(int i=0i<locationFlags.length();i++)
 {

   Drawable drawable = locationFlags.getResourceId(i, -1);
 }

Be sure to recycle the TypedArray after using it, since its a shared resource :

 locationFlags.recycle();

the best way was to store image name directly into database and fetch it,then use

int resID = this.getResources().getIdentifier("your photo name fetched from database","drawable","package name");

image.setResourceID(resID);
