だから私はアプリを開発し、それをプレイストアにアップロードしたかったのですが、com.example.app_nameとは異なるパッケージ名を変更する必要があると言われたとき、私はそれを変更しました. しかし、今私はエラーが発生しています:

ここに私のコードがあります:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.activity_home);
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
imv = (ImageView) findViewById(R.id.imvFoto);
onderwerp = (TextView) findViewById(R.id.txtSubject);
commentaar = (TextView) findViewById(R.id.txtComment);
if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
showGPSDisabledAlertToUser();
}
}
public void getGPSLocation() {
if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
showGPSDisabledAlertToUser();
}
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MINIMUM_TIME_BETWEEN_UPDATES, MINIMUM_DISTANCE_CHANGE_FOR_UPDATES, new MyLocationListener());
currentLocation = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (currentLocation != null) {
longitude = currentLocation.getLongitude();
latitude = currentLocation.getLatitude();
}
EXTRA_TEXT = "http://maps.google.com/maps?q=" + latitude + "," + longitude;
}
}
助けてください、これは非常に重要です!!!!
