i want to check which app is currently running if it match it show Message. Here is code of my service
public class MyService extends Service{
Context context;
ActivityManager am ;
List<ActivityManager.RunningAppProcessInfo> runningAppProcessInfo;
Dbheltool db;
String packname;
String key;
HashMap<String, String> list;
public MyService(Context context) {
// TODO Auto-generated constructor stub4
this.context=context;
db=new Dbheltool(context);
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
Toast.makeText(this, "The new Service was Created", Toast.LENGTH_LONG).show();
am = (ActivityManager) getSystemService(context.ACTIVITY_SERVICE);
runningAppProcessInfo = am
.getRunningAppProcesses();
try{
db.open();
list=(HashMap)db.getPackage();
db.close();
}catch (java.sql.SQLException e) {
// TODO Auto-generated catch block
Toast.makeText(context, "Exception", Toast.LENGTH_SHORT);
}
}
@Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
Toast.makeText(this, " Service Started", Toast.LENGTH_LONG).show();
if(isThisApplicationRunning(context)){
Toast.makeText(context, "Success", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
}
public boolean isThisApplicationRunning(final Context context) {
for (final RunningAppProcessInfo app : runningAppProcessInfo) {
try{
if(list.get(app.processName.toString()).equals(app.processName.toString())) {
return true
}
}
catch(NullPointerException e){
}
}
return false;
}
}
