Android gets the running program and kill it.

Android gets the running program and kill it.

Obtain the running program and add it to the adapter class of a listview. The method is as follows:

// The public List that is running
 
  
GetRunningProcess () {pi = new PackagesInfo (this); am = (ActivityManager) getSystemService (ACTIVITY_SERVICE); // get the running application run = am. getRunningAppProcesses (); // obtain the Package Manager. Here, the package name is used to obtain the program icon and program name pm = this. getPackageManager (); List
  
   
List = new ArrayList
   
    
(); For (RunningAppProcessInfo ra: run) {// here it mainly filters out system applications and phone applications. Of course, you can also comment it out. If (ra. processName. equals ("system") | ra. processName. equals ("com. android. phone ") {continue;} if (pi. getInfo (ra. processName) = null) {continue;} int [] myMempid = new int [] {ra. pid}; Programe pr = new Programe (); String xx = "" + ra. processName; Log. d ("zphlog", "ra. processName = "+ xx); pr. setIcon (pi. getInfo (ra. processName ). loadIcon (pm); pr. setName (pi. getInfo (ra. processName ). loadLabel (pm ). toString (); System. out. println (pi. getInfo (ra. processName ). loadLabel (pm ). toString (); // PIDpr. setPID ("PID:" + ra. pid); // memoryDebug. memoryInfo [] memoryInfo = am. getProcessMemoryInfo (myMempid); double memSize = memoryInfo [0]. dalvikPrivateDirty/1024.0; int temp = (int) (memSize * 100); memSize = temp/100.0; pr. setMemory ("Memory:" + memSize); list. add (pr);} return list ;}
   
  
 

The following describes how to obtain the remaining running memory of a running program on the mobile phone:

// Update available memory information public void updatemandpakinfo () {// get MemoryInfo object ActivityManager. memoryInfo memoryInfo = new ActivityManager. memoryInfo (); // obtain the available memory of the system, which is saved on the MemoryInfo object am. getMemoryInfo (memoryInfo); long memSize = memoryInfo. availMem; // character type conversion String restMemSize = Formatter. formatFileSize (getBaseContext (), memSize); mRestMemory. setText ("available space:" + restMemSize); // mPakcgeNums. setText (run. size (); mPakcgeNums. setText ("running:" + run. size () + "count ");}

List_item.xml

The above are the main implementation code. Due to the length, I will not continue to paste the code here. I will summarize my ideas.

First, I first talked about getting information about a running program.

You can use the following method to obtain

// Running
Public List GetRunningProcess (){
Pi = new PackagesInfo (this );


Am = (ActivityManager) getSystemService (ACTIVITY_SERVICE );
// Obtain the running application
Run = am. getRunningAppProcesses ();
// Obtain the Package Manager. The package name is used to obtain the program icon and program name.
Pm = this. getPackageManager ();
List List = new ArrayList ();


For (RunningAppProcessInfo ra: run ){
// Here, we mainly filter out system applications and phone applications. Of course, you can also comment it out.
If (ra. processName. equals ("system ")
| Ra. processName. equals ("com. android. phone ")){
Continue;
}
If (pi. getInfo (ra. processName) = null ){
Continue;
}
Int [] myMempid = new int [] {ra. pid };
Programe pr = new Programe ();
String xx = "" + ra. processName;
Log. d ("zphlog", "ra. processName =" + xx );
Pr. setIcon (pi. getInfo (ra. processName). loadIcon (pm ));
Pr. setName (pi. getInfo (ra. processName). loadLabel (pm). toString ());


System. out. println (pi. getInfo (ra. processName). loadLabel (pm)
. ToString ());
// PID
Pr. setPID ("PID:" + ra. pid );
// Memory
Debug. MemoryInfo [] memoryInfo = am. getProcessMemoryInfo (myMempid );
Double memSize = memoryInfo [0]. dalvikPrivateDirty/1024.0;
Int temp = (int) (memSize * 100 );
MemSize = temp/100.0;
Pr. setMemory ("Memory:" + memSize );


List. add (pr );
}
Return list;
}

Then, the information is saved in an Adapter of the listview.

The next step is to kill them. I can see three methods on the Internet to kill the program. The method I use here is

For (RunningAppProcessInfo ra: run) {// here, it mainly filters out system applications and phone applications. Of course, you can also comment it out. If (ra. processName. equals ("system") | ra. processName. equals ("com. android. phone ") {continue;} if (pi. getInfo (ra. processName) = null) {continue;} am. killBackgroundProcesses (ra. processName); // Log. d ("zphlog", "pid =" + ra. pid );}

Of course, it is carried out in the for loop, followed by some other things, such as scanning a running program at startup takes some time, we can let the program read an image when it is started, and wait for two or three seconds to get the running program list information loading time.

I used an Activity named StartUI. java.

public class StartUI extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);setContentView(R.layout.welcome_activity);new Handler().postDelayed(new Runnable() {@Overridepublic void run() {Intent intent = new Intent(StartUI.this, ActivityMain.class);startActivity(intent);StartUI.this.finish();}}, 2500);}}

Its Layout file is actually a simple ImageView.
