I use bind service in Android .I start Service and stop Service with button and it work correctly.The story: I press start service button so Service start then,I increase x with showint button and x increase well, then I close App without stopping service then run App again , but public x turn to zero and initial again.I need service without re-initial public variable.How can i do that? How can bind .
public class MainActivity extends AppCompatActivity {
BoundService mBoundService;
boolean mServiceBound = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TextView timestampText = (TextView) findViewById(R.id.timestamp_text);
Button shownum = (Button) findViewById(R.id.shownum);
Button stopService= (Button) findViewById(R.id.stop_service);
Button start = (Button) findViewById(R.id.start);
shownum.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (mServiceBound) {
timestampText.setText(mBoundService.shownum());
}
}
});
stopService.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (mServiceBound) {
unbindService(mServiceConnection);
mServiceBound = false;
}
Intent intent = new Intent(MainActivity.this,
BoundService.class);
stopService(intent);
}
});
start.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, BoundService.class);
startService(intent);
bindService(intent, mServiceConnection, Context.BIND_AUTO_CREATE);
}
});
}
private ServiceConnection mServiceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
BoundService.MyBinder myBinder = (BoundService.MyBinder) service;
mBoundService = myBinder.getService();
mServiceBound = true;
}
@Override
public void onServiceDisconnected(ComponentName name) {
mServiceBound = false;
}
};
}
and BoundService class:
public class BoundService extends Service {
private IBinder mBinder = new MyBinder();
public int x;
@Override
public void onCreate() {
// super.onCreate();
Toast.makeText(this,"onCreate",Toast.LENGTH_SHORT).show();
}
@Override
public IBinder onBind(Intent intent) {
Toast.makeText(this,"onBind",Toast.LENGTH_SHORT).show();
return mBinder;
}
@Override
public void onRebind(Intent intent) {
Toast.makeText(this,"onRebind",Toast.LENGTH_SHORT).show();
super.onRebind(intent);
}
@Override
public boolean onUnbind(Intent intent) {
Toast.makeText(this,"UUUUnbind",Toast.LENGTH_SHORT).show();
return true;
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this,"onDestroy",Toast.LENGTH_SHORT).show();
}
public String shownum()
{
x++;
return String.valueOf(x);
}
public class MyBinder extends Binder {
BoundService getService() {
return BoundService.this;
}
}
}
