我有一个可穿戴设备,我正在尝试连接到GoogleApiClient但是从不调用回调(onConnected,onConnectionSuspended或onConnectionFailed)。其他所有工作正常,DataLayerListenerService能够从掌上电脑接收消息,并在连接时调用onPeerConnected。我试过了仿真器和三星Gear Live设备。这是我在Activity中的代码,我正在尝试连接到GoogleApiClient。
public class WearReaderActivity extends Activity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
public static final String CONTENT_EXTRA = "contentExtra";
private String LOG_TAG = WearReaderActivity.class.getSimpleName();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.reader);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
}
private GoogleApiClient mGoogleApiClient;
@Override
protected void onStart() {
super.onStart();
Log.e("Connected?", String.valueOf(mGoogleApiClient.isConnected()));
//new Thread(new GetContent()).start();
}
@Override
public void onConnected(Bundle bundle) {
Log.d("Connected", "Connected");
new Thread(new GetContent()).start();
}
@Override
public void onConnectionSuspended(int i) {
Log.d("Connection suspened", "Connection suspended");
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.d("Connection suspened", "Connection suspended");
}
...
}
不确定它是否有帮助,但这是我的可穿戴应用程序的清单
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="my.packagename">

有什么想法吗?
编辑:将以下内容添加到可穿戴清单中,但仍无法正常工作
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

onStart()
您需要致电mGoogleApiClient.connect()
的部分。
答案 1 :(得分:3)
您可以在onStart和onStop生命周期方法中手动调用connect和disconnect,也可以使用enableAutoManage
功能。
mCredentialsApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.enableAutoManage(this, this)
.addApi(Auth.CREDENTIALS_API)
.build();
答案 2 :(得分:0)
此外,我注意到如果您在用户未设置Google Play时尝试使用GoogleApiClient,则可能会发生冲突连接。 (我只是重置我的设备,这就是发生的事情)。因此,使用
测试来自GoogleApiClient的连接是一种很好的做法mCredentialsApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
或者在执行任何任务之前检查mCredentialsApiClient.isConnected()。
