所以我找到了关于GoogleApiClient的一些不太清楚的东西. GoogleApiClient有一个名为onConnected的函数,它在客户端连接时运行(肯定)

我得到了自己的函数:startLocationListening,最终在GoogleApiClient的onConnected函数上调用.

所以我的startLocationListening函数无法在没有GoogleApiClient连接的情况下运行.

代码和日志:

@Override
public void onConnected(Bundle bundle) {
    log("Google_Api_Client:connected.");
    initLocationRequest();
    startLocationListening(); //Exception caught inside this function
}

...

private void startLocationListening() {
    log("Starting_location_listening:now");

    //Exception caught here below:
    LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
   }

例外是:

我们在崩溃时遇到了这种崩溃,奇怪的是它在onConnected()请求位置更新时会在回调中发生.

码:

abstract public class MainService_6_LocationClient extends MainService_5_DriverGpsLocationStoring
    implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {


  private LocationListener highAccuracyListener;
  private GoogleApiClient googleApiClient;
  private LocationRequest gpsRequest;

  @Override
  public void onCreate() {
    super.onCreate();
    lazyInit();
    googleApiClient.connect();
  }

  @Override public void onConnected(Bundle bundle) {
    Log.d(TAG, "onConnected");
    lazyInit();
    LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, gpsRequest,
          highAccuracyListener);
  }

  private void lazyInit() {

    if (highAccuracyListener == null) {
      highAccuracyListener = new HighAccuracyLocationListener();
    }

    if (googleApiClient == null) {
      googleApiClient = new GoogleApiClient.Builder(this).addApi(LocationServices.API)
          .addConnectionCallbacks(this)
          .addOnConnectionFailedListener(this)
          .build();
    }

    if (gpsRequest == null) {
      gpsRequest = new …

我无法将高分数提交给Android排行榜.现在排行榜是空的,没有提交任何内容.我有一个需要提交的int"oldScore".现在我正在尝试一段代码来提交它,但活动在被调用时崩溃了.我的代码:

public class GameOver extends BaseGameActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

    private GoogleApiClient mGoogleApiClient;
    public static int score;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_game_over);

        mGoogleApiClient.connect();
        mGoogleApiClient = new GoogleApiClient.Builder(this)
        .addApi(Drive.API)
        .addScope(Drive.SCOPE_FILE)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .build();

        int newScore = GameOver.score;

        SharedPreferences prefs = this.getSharedPreferences("myPrefsKey", Context.MODE_PRIVATE);

        int oldScore = prefs.getInt("key", 0);
        if (newScore > oldScore) {
            SharedPreferences.Editor edit = prefs.edit();
            edit.putInt("key", newScore);
            edit.commit();

            EditText HighScore = (EditText) findViewById(R.id.HighScoreT);
            HighScore.setText("" + newScore);
        } else {
            EditText HighScore = (EditText) findViewById(R.id.HighScoreT);
            HighScore.setText("" + oldScore); …
