title: How can I kill processes in Android?
body: <p>I have this code below:</p>
  
  <pre><code>package com.example.killall;
  
  import android.os.Bundle;
  import android.app.Activity;
  import android.view.Menu;
  import android.view.View;
  import android.widget.Button;
  //import android.widget.TextView;
  import android.app.ActivityManager;
  
  public class MainKill extends Activity {
  
  private Button BprocessesKill ;
  //private TextView processesKill;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main_kill);
  
      final ActivityManager am=(ActivityManager)     getSystemService("SYSTEM_ACTIVITY");
  
      BprocessesKill=(Button) this.findViewById(R.id.BkillProcesses);
      //processesKill=(TextView) this.findViewById(R.id.killProcesses);
  
  
  
      BprocessesKill.setOnClickListener(new View.OnClickListener() {
  
          @Override
          public void onClick(View arg0) {
              am.killBackgroundProcesses(getPackageName());
  
          }
      });
  
  }
  
  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
      // Inflate the menu; this adds items to the action bar if it is present.
      getMenuInflater().inflate(R.menu.main_kill, menu);
      return true;
  }
  
  }
  </code></pre>
  
  <p>All I want to do is simply to press the button and kill all background processes.. the problem I have with this code is that when I am pressing the button it shows me the message : Unfortunately KillAll(that's my app's name) has stopped. What should I change?</p>
