2 つの主な処理を行う次のコードがあります。
- Google Play サービスに接続します。
- onConnected() メソッド内で startService(...) メソッドを呼び出すことにより、サービスが開始されます。
プログラムを実行すると、次のログ メッセージが表示されます。
Connected!!!
Fit wasn't able to connect, so the request failed.
GoogleFitService destroyed.
これが私のコードです：
public class MainActivity extends ActionBarActivity {
public final static String TAG = "GoogleFitService";
private static final int REQUEST_OAUTH = 1;
private static final String AUTH_PENDING = "auth_state_pending";
private boolean authInProgress = false;
private GoogleApiClient mClient = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buildFitnessClient();
}
private void buildFitnessClient() {
// Create the Google API Client
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.API)
.addConnectionCallbacks(
new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle bundle) {
Log.i(TAG, "Connected!!!");
// Now you can make calls to the Fitness APIs.
// Put application specific code here.
Intent service = new Intent(MainActivity.this,
GoogleFitService.class);
service.putExtra(GoogleFitService.SERVICE_REQUEST_TYPE,
GoogleFitService.TYPE_REQUEST_CONNECTION);
startService(service);
}
@Override
public void onConnectionSuspended(int i) {
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost. Cause: Network Lost.");
} else if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG, "Connection lost. Reason: Service Disconnected");
}
}
}
)
.addOnConnectionFailedListener(
new GoogleApiClient.OnConnectionFailedListener() {
// Called whenever the API client fails to connect.
@Override
public void onConnectionFailed(ConnectionResult result) {
Log.i(TAG, "Connection failed. Cause: " + result.toString());
if (!result.hasResolution()) {
// Show the localized error dialog
GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(), MainActivity.this, 0).show();
return;
}
if (!authInProgress) {
try {
Log.i(TAG, "Attempting to resolve failed connection");
authInProgress = true;
result.startResolutionForResult(MainActivity.this, REQUEST_OAUTH);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG, "Exception while starting resolution activity", e);
}
}
}
}
)
.build();
}
@Override
protected void onStart() {
super.onStart();
// Connect to the Fitness API
Log.i(TAG, "Connecting...");
mClient.connect();
Intent service = new Intent(this, GoogleFitService.class);
service.putExtra(GoogleFitService.SERVICE_REQUEST_TYPE, GoogleFitService.TYPE_REQUEST_CONNECTION);
startService(service);
}
@Override
protected void onStop() {
super.onStop();
if (mClient.isConnected()) {
mClient.disconnect();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_OAUTH) {
authInProgress = false;
if (resultCode == RESULT_OK) {
// Make sure the app is not already connected or attempting to connect
if (!mClient.isConnecting() && !mClient.isConnected()) {
mClient.connect();
}
}
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putBoolean(AUTH_PENDING, authInProgress);
}
}
2 番目のクラスは基本的に Intent サービスです。間違いはここにあるのかもしれません。
public class GoogleFitService extends IntentService {

何がうまくいかなかったのでしょうか？ありがとう、テオ。
