android.os.StrictMode instances=2; limit=1
<p>I use the <code>StrictMode</code> in my application , the api android 4.0.3, in my <code>BaseApp</code>
i detect all.</p>

<pre><code>    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);
</code></pre>

<p>then. I just call the  <code>this.finish()</code> , 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?</p>

<pre><code>06-27 14:47:34.725: E/StrictMode(18592): class com.onecard.ui.business.AllBusinessActivity; instances=2; limit=1
06-27 14:47:34.725: E/StrictMode(18592): android.os.StrictMode$InstanceCountViolation: class com.onecard.ui.business.AllBusinessActivity; instances=2; limit=1

</code></pre>
