java - WatchFaces 未配置

Question

我已经为Android Wear创建了表盘，我的代码如下:

ComapnionConfigActivity(在移动模块中):

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.wearable.Wearable;


public class CompanionConfigActivity extends ActionBarActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

    private GoogleApiClient mGoogleApiClient;


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

        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(Wearable.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();
    }

    @Override
    protected void onStart() {
        super.onStart();
        mGoogleApiClient.connect();
    }
    @Override
    protected void onStop() {
        mGoogleApiClient.disconnect();
        super.onStop();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_watch_config, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }


        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onConnected(Bundle bundle) {

    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {

    }
}

移动模块 list :

我已按照官方指南创建表盘。但是，当我安装该应用程序时，它没有显示在配套应用程序中。问题似乎出在 list 或同伴配置 Activity 中。我试了一天多了，还是无法识别。谁能帮帮我吗？

Answer 1

在您的可穿戴 list 中，您有以下行:

<category android:name="com.example.agile.mywatchface.category.WATCH_FACE" />

这是不正确的，您需要使用

<category android:name="com.google.android.wearable.watchface.category.WATCH_FACE" />

Android Wear 在过滤器中查找具有此类别的服务，如果您使用自定义类别，它将忽略您的服务。
