私はGPS追跡アプリケーションの主な目標は、5分間隔ごとにバックアップされたデータベースにGPS座標を保存することです。だから私はService & receiver私のアプリケーションも開いていない/これは動作する必要があります実行するため、作成しました。broadcastReceiverからサービスメソッドを呼び出す方法は？
ユーザーがエグゼクティブコードを入力すると、データベースが作成され、ウェルカム画面に移動します。 そこにそれを捕獲開始する&アップロードするPDAデータベースの呼出しサービスにそれを保存しなさい。私は受信機を持っています、電話がBootedの場合、この受信機を起動します&受信機のコールサービス。
私の問題は、受信者がサービスを呼び出さないことです。それはサービスクラスには行きませんでした。
protected void onStop(){
super.onStop();
if(gpsReceiver != null){
unregisterReceiver(gpsReceiver);
}
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
gpsReceiver = new GpsReceiver();
IntentFilter intentFilter1 = new IntentFilter(Intent.ACTION_BOOT_COMPLETED);
intentFilter1.addAction(Intent.ACTION_BOOT_COMPLETED);
intentFilter1.addAction(Intent.ACTION_POWER_CONNECTED);
intentFilter1.addAction(Intent.ACTION_SCREEN_ON);
registerReceiver(gpsReceiver, intentFilter1);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MINIMUM_TIME_BETWEEN_UPDATES,
MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
new MyLocationListener()
);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, new MyLocationListener());
}
private class MyLocationListener implements LocationListener {
public void onLocationChanged(Location location) {
String message = String.format("Location \n Longitude: %1$s \n Latitude: %2$s", location.getLongitude(), location.getLatitude());
longitude = location.getLongitude();
latitude =location.getLatitude();
//save GPS coordinate to PDA DB
GPSDBAdapter dbAdapter = GPSDBAdapter.getDBAdapterInstance(HomeActivity.this);
dbAdapter.openDataBase();
dbAdapter.insertGPS(longitude, latitude, "MASS", deserializeObject());
dbAdapter.close();
//After save GPS coordinate it upload to backend using service
startService(new Intent(HomeActivity.this, UploadService.class));
Toast.makeText(HomeActivity.this, message, Toast.LENGTH_LONG).show();
}
public void onStatusChanged(String s, int i, Bundle b) {
Toast.makeText(HomeActivity.this, "Provider status changed",Toast.LENGTH_LONG).show();
}
public void onProviderDisabled(String s) {
Toast.makeText(HomeActivity.this,"Provider disabled by the user. GPS turned off",Toast.LENGTH_LONG).show();
}
public void onProviderEnabled(String s) {
Toast.makeText(HomeActivity.this, "Provider enabled by the user. GPS turned on",Toast.LENGTH_LONG).show();
}
}
これは私の受信機です。

System.out.println(" Receiver done");
Intent serviceIntent = new Intent(context,UploadService.class);

問題、それはサービスクラスに行きませんでしたです。
...この質問を私を助けて事前に
感謝してください。..
System.out.println（ "Receiver done"）をチェックした場合;やってくる？ –
いいえ、それはどこにも来なかった。私は受信機から呼び出さずに、アクティビティから呼び出さずに試してみました。サービスクラスには来ていませんでした。 – Piraba
マニフェストファイルではパッケージ名が正しくないと思います。 –
