Android NoSuchField error in R.java after process is killed

Question

I've hit a very frustrating issue with one of my apps.

I have a splashscreen activity which loads up some initial data for my app then launches the main activity and finishes itself.

Once main activity is running, I background the app by pressing the home key and then kill the process for my app.

When I relaunch my app, the splashscreen tries to run but fails as soon as I try to access any of the fields in my R.java file:

For example, I immediately try to set the text of a textview like so:

((TextView)findViewById(R.id.splash_tv_1)).setText(application.getLanguage().pleasewait);

This throws the following exception:

06-29 11:18:14.661: ERROR/AndroidRuntime(21427): java.lang.NoSuchFieldError: com.pagesuite.android.reader.framework.R$id.splash_tv_1

Then when I launch it again it's fine.

I get the same behaviour if I kill the app using a TaskKiller tool (something I know a lot of users will be naively using I suspect) or if the OS kills my process.

Any ideas?

EDIT:

Just noticed in the logcat, just before onCreate() of this activity executes, the following is logged:

06-29 11:18:14.571: WARN/dalvikvm(21427): VFY: unable to resolve static field 1945 (splash_logo) in Lcom/pagesuite/android/reader/framework/R$id;

These are the three instances where I try to access R.id in my class.

One thing to note is that I do call:

setContentView(R.layout.ps_splashscreen);

and it seems to run this line fine, so it is the R.id's specifically that seem to be missing.

EDIT: Here is the layout:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:orientation="vertical" 
    android:gravity="center">

    <ImageView
        android:id="@+id/splash_logo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />


    <TextView
        android:id="@+id/splash_tv_1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Please wait"
        android:textColor="@color/white"
        android:textSize="20dip" />

    <TextView
           android:id="@+id/splash_tv_2"
        android:layout_marginTop="20dip"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Loading..."
        android:textColor="@color/white" />

</LinearLayout>

Answer 1

i had the same problem and it gave me

DexOpt: couldn't find static field

error because i had two layout xml files with the same name, one in an external library one in the project. I don't know if this can be useful to others :)
