i m Getting an error when i run my mapFragment.getMapAsync(this)
i works very well for first time ...when i start again its giving error like above ...everything works well for first time ....it is like for odd it works for even application crashesh.

I have implemented following coding in my app.i used camera 2 api for video recording.i feel that video streaming is stretched. mainly when i switch camera into front one.pls help me to resolve this problem

Change aspect ratio values in AutoFitTextureView class or use Textureview instead of AutoFitTextureview.

My Program Creates 1 Ball not 2

I made a program that creates a frame and then creates 2 balls and moves them around seperately, my problem is that somehow the first or second ball is getting the coordinates of the other, and therefore are being painted on each other, sorry for the bad indentation this is my first time posting a question .
Main Class:
public class Game extends JPanel {
Ball ball01 = new Ball();
Ball ball02 = new Ball();
int ball01x = 0,ball01y = 0,ball02x = 0,ball02y = 0;
public void paint(Graphics g) {
super.paint(g);
Graphics2D g2d = (Graphics2D) g;
g2d.fillOval(ball01x, ball01y, 10, 10);
g2d.setColor(Color.RED);
g2d.fillOval(ball02x, ball02y, 10, 10);
}
public static void main(String[] args) throws InterruptedException {
JFrame frame = new JFrame("Sample Frame");
Game game = new Game();
frame.add(game);
frame.setSize(400, 400);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
game.createBalls();
while (true) {
game.getCoords();
game.updateBalls();
game.repaint();
System.out.println("Ball01 x: " + game.ball01x + " Ball02 x " + game.ball02x);
Thread.sleep(10);
}
}
public void getCoords(){
ball01x = ball01.getX();
ball01y = ball01.getY();
ball02x = ball02.getX();
ball02y = ball02.getY();
}
public void createBalls(){
ball01.create(300,300);
ball02.create(50,20);
}
public void updateBalls(){
ball01.Ball();
ball02.Ball();
}
}

How to limit a float to give one or no value after the decimal

I'm working in Eclipse and using float for my variables and values. The only issue I am getting is the huge number of digits (1.563524354) after the decimal. Can I somehow limit them to one digit after the decimal like (1.5) or no digit or decimal at all simply like 1. ?
My code:
float nCurrentSpeed;
private long startTime;
private int count;
private int pointAverage;
private Float nMaxSpeed = 0F;
DecimalFormat df = new DecimalFormat("#");
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LocationManager lm = (LocationManager) this
.getSystemService(Context.LOCATION_SERVICE);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
this.onLocationChanged(null);
}
#Override
public void onLocationChanged(Location location) {
TextView tv = (TextView) findViewById(R.id.textView1);
TextView tvd = (TextView) findViewById(R.id.textView5);
if (location == null) {
startTime = System.currentTimeMillis();
count = 0;
pointAverage = 0;
actualizeTextField();
tv.setText("0.0");
} else {
nCurrentSpeed = location.getSpeed();
tv.setText(nCurrentSpeed + "");
count += 1;
pointAverage += location.getSpeed();
actualizeTextField();
if (nMaxSpeed < nCurrentSpeed) {
nMaxSpeed = nCurrentSpeed;
}
}
tvd.setText(nMaxSpeed.toString());
}
private void actualizeTextField() {
// TODO Auto-generated method stub
TextView tf = (TextView) findViewById(R.id.textView3);
if (count > 0) {
long timeOver = System.currentTimeMillis() - startTime;
tf.setText(String.valueOf(pointAverage / (timeOver / 1000)));
} else {
tf.setText("0.0");
}
}
DecimalFormat df = new DecimalFormat("#.#");
df.format(0.91231);
returns:
0.9
If you don't want decimal places, why don't you cast it to int then?
Like this :
double d = 1.234567;
DecimalFormat df1 = new DecimalFormat("#.##"); // set your format
System.out.print(df1.format(d))
If you don't need point values, why are you using float? Check this one.

private long startTime;
private int count;
private int pointAverage;
private int nMaxSpeed = 0;
