Android地图API，异常 [英] android maps api, exception

问题描述

使用谷歌地图V2 IM。

我的code为crached的方法：

 公共无效onConnected（束捆）{
    mLastLocation = LocationServices.FusedLocationApi.getLastLocation（mGoogleApiClient）;
如果（mLastLocation！= NULL）{
    mLatitudeText.setText（将String.valueOf（mLastLocation.getLatitude（）））;
        mLongitudeText.setText（将String.valueOf（mLastLocation.getLongitude（）））;
}
 } //结束onConnected
 

logcat的：

  10月三号至25日：30：41.120 25816-25816 /？ E /dalvikvm﹕找不到类的android.app.AppOpsManager，从法com.google.android.gms.common.GooglePlayServicesUtil.zza引用
十月三号至25日：30：41.460 25816-25816 /？ E /AndroidRuntime﹕致命异常：主要
显示java.lang.NullPointerException
    在com.example.robot.myapplication.MainActivity.onConnected（MainActivity.java:66）
 

我是怎么想的，除了在这一行：

  mLastLocation = LocationServices.FusedLocationApi.getLastLocation（** mGoogleApiClient **）;
 

但我已经创建该对象（mGoogleApiClient）：

  mGoogleApiClient =新GoogleApiClient.Builder（本）
        .addConnectionCallbacks（本）
        .addOnConnectionFailedListener（本）
        .addApi（LocationServices.API）
        。建立（）;
 

什么我错了？

满code：

 公共类MainActivity扩展活动器具
GoogleApiClient.ConnectionCallbacks，GoogleApiClient.OnConnectionFailedListener {
    私人GoogleApiClient mGoogleApiClient;

私人的位置mLastLocation;
TextView的mLatitudeText;
TextView的mLongitudeText;
私人最终静态INT CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;
私有静态最终诠释REQUEST_RESOLVE_ERROR = 1001;

im using google maps v2.

my code is crached at method:

public void onConnected(Bundle bundle) {
    mLastLocation =     LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (mLastLocation != null) {
    mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
        mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
}
 } // end onConnected

logcat:

03-25 10:30:41.120  25816-25816/? E/dalvikvm﹕ Could not find class            'android.app.AppOpsManager', referenced from method             com.google.android.gms.common.GooglePlayServicesUtil.zza

java.lang.NullPointerException
    at         com.example.robot.myapplication.MainActivity.onConnected(MainActivity.java:66)

how i think, exception in this line:

mLastLocation =         LocationServices.FusedLocationApi.getLastLocation(**mGoogleApiClient**);

but i already create this object (mGoogleApiClient):

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

whats wrong with me?

full code:

public class MainActivity extends Activity implements
GoogleApiClient.ConnectionCallbacks,                     GoogleApiClient.OnConnectionFailedListener  {
    private GoogleApiClient mGoogleApiClient;

private Location mLastLocation;
TextView mLatitudeText;
TextView mLongitudeText;
private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;
private static final int REQUEST_RESOLVE_ERROR = 1001;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView mLatitudeText = (TextView) findViewById(R.id.mLatitudeText);
TextView mLongitudeText = (TextView) findViewById(R.id.mLongitudeText);
mGoogleApiClient = new GoogleApiClient.Builder(this)
        .addConnectionCallbacks(this)
        .addOnConnectionFailedListener(this)
        .addApi(LocationServices.API)
        .build();
}
@Override
protected void onResume() {
super.onResume();
mGoogleApiClient.connect();
}
@Override
protected void onPause() {
super.onPause();
 mGoogleApiClient.disconnect();
}
@Override
public void onConnected(Bundle bundle) {
mLastLocation =         LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (mLastLocation != null) {
    mLatitudeText.setText(String.valueOf(mLastLocation.getLatitude()));
        mLongitudeText.setText(String.valueOf(mLastLocation.getLongitude()));
}
 } // end onConnected
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(ConnectionResult result) {
if (result.hasResolution()) {
    try {
        result.startResolutionForResult(this, REQUEST_RESOLVE_ERROR);
    }
    catch (IntentSender.SendIntentException e) {
        e.printStackTrace();
    }
} //end if

} // end onConnectionFailed
}

Change your api version and recheck google play services.
