小编Sar*_*eth的帖子

我很惭愧.但是找不到什么是错的.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.szymon.gpslab1"
android:versionCode="15"
android:versionName="4.0.3">

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"

        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />

    </activity>
</application>
</manifest>

public class MainActivity extends AppCompatActivity {
LocationManager locationManager;
LocationListener locationListener;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    locationListener = new MyLocationListener();

    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
}
