    <p>I want to develop a task manager like application where I want to display the list of runnung services and the memory used by each service in a list view.</p> <p>I figured that running services can be obtained using</p> <pre><code>ActivityManager am = (ActivityManager)this.getSystemService(Context.ACTIVITY_SERVICE); List&lt;RunningServiceInfo&gt; procInfos = am.getRunningServices(maxNum); </code></pre> <p>But how to dislay them in a ListView and also how to obtain the memory used by each one of them? I am an android beginner and I wish anyone could explain me in a detailed manner...</p> <p>I tried the following. I could see the service name etc in logcat but the apllication is force closing.</p> <pre><code> package com.example.ServiceList; import java.util.List; import android.app.Activity; import android.app.ActivityManager; import android.app.ActivityManager.MemoryInfo; import android.app.ActivityManager.RunningAppProcessInfo; import android.app.ActivityManager.RunningServiceInfo; import android.content.Context; import android.os.Bundle; import android.util.Log; import android.widget.TextView; public class ServiceListActivity extends Activity { /** Called when the activity is first created. */ int maxNum = 5; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); this.setContentView(tv); android.os.Debug.MemoryInfo[] mInfo; int[] processid = null; ActivityManager am = (ActivityManager)this.getSystemService (Context.ACTIVITY_SERVICE); List&lt;RunningServiceInfo&gt; procInfos = am.getRunningServices(maxNum); for(int i = 0; i &lt; procInfos.size(); i++){ tv.setText(tv.getText().toString()+ " " + "\n"); Log.v("TaskMgr Stringe", procInfos.get(i).service.toString()); Log.v("TaskMgr class name", procInfos.get(i).service.getClassName()); processid[i]=procInfos.get(i).pid; String s = " "+processid[i]; Log.v("TaskMgr process id",s ); Log.v("TaskMgr process memory", am.getProcessMemoryInfo(processid[0]); } mInfo = am.getProcessMemoryInfo(processid); int dp= mInfo[0].dalvikPss; String s1= " " + dp; tv.setText(tv.getText().toString()+ " " + s1 ); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
