android.os.StrictMode instances=2; limit=1

Question

I use the StrictMode in my application , the api android 4.0.3, in my BaseApp i detect all.

    builder.detectAll();
    builder.penaltyLog(); 
    StrictMode.VmPolicy vmp = builder.build();
    StrictMode.setVmPolicy(vmp);

    StrictMode.ThreadPolicy.Builder builder1= new StrictMode.ThreadPolicy.Builder();
    builder1.detectAll();
    builder1.penaltyLog();
    StrictMode.ThreadPolicy tdp=builder1.build();
    StrictMode.setThreadPolicy(tdp);

then. I just call the this.finish() , in my activity : always show this error. why? whether I use the android:launchMode="singleInstance" in my Manifest.xml,they always show this error why?
