我目前正在开发Google Map当前位置应用程序。一切都很好，没有检测到错误。
当我运行我的应用程序时，Google Map可以加载但不显示我当前的位置。
所以我把logcat放在这里，请有人帮助我。它与
有关＆＃34; Asset path＆＃39; /system/framework/com.android.media.remotedisplay.jar' 不存在或不包含任何资源。＆＃34;
？我对此做了一些研究，但找不到解决方案。

答案 0 :(得分：1)
默认情况下，地图不会显示您的位置。位置由不同的服务提供：Google Play位置API（supersedes Android位置API）。
这是实现它的最低代码。 首先在清单中添加这些
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
然后，您需要在地图活动
中构建GoogleApiClientpublic class MyMapActivity extends Activity {
private GoogleMap googleMap;
private GoogleApiClient mGoogleApiClient;
protected Location mLastLocation;
@Override
public void onCreate(Bundle inState) {
// do whatever initialization including one for googleMap
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(Bundle arg0) {
// this is where you got your last location
mLastLocation = LocationServices.FusedLocationApi
.getLastLocation(mGoogleApiClient);
// then center on map
LatLng mLatLng = new LatLng(mLastLocation.getLatitude(),
mLastLocation.getLongitude());
googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom
(mLatLng, 14), 1000, null);
}
@Override
public void onConnectionSuspended(int arg0) {
}
})
.addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(ConnectionResult conResult) {
if (conResult.hasResolution()){
try{
conResult.startResolutionForResult(MyMapActivity.this,
CONNECTION_FAILURE_RESOLUTION_REQUEST);
}catch(SendIntentException e){
e.printStackTrace();
}
}
}})
.addApi(LocationServices.API)
.build();
}
}
@Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
@Override
protected void onStop() {
super.onStop();
mGoogleApiClient.disconnect();
}
这是official how-to以供参考。
下一个问题是您正在使用模拟器，因此您需要模拟模拟位置。此链接将更好地解释如何：How to emulate GPS location in the Android Emulator?
