无法在 android api23 上打开位置?
Can't turn on location on android api23?
我使用了以下代码,请求权限的对话按预期显示。但是当我点击 "allow" 时,它什么也没做。日志消息没有出现,好像没有授予权限,所以我转到我的参数来验证位置是否为 "on" 并且它是 "off"。它不应该是因为我授予应用程序访问我的位置的权限吗?
如果我手动打开它 "on" 然后再次 运行 应用程序,一旦它请求我的许可,它就会工作并显示日志消息但不是请求权限的全部意义(通过对话)如果用户点击 "allow" 打开位置(当它关闭时)?
难道我做错了什么 ?我应该提到我 运行 在 api23
上安装应用程序
是我的 Oncreate:
中的代码
mApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mApiClient.connect();
// Create the LocationRequest object
mLocationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(10 * 1000) // 10 seconds, in milliseconds
.setFastestInterval(1 * 1000); // 1 second, in milliseconds
这是我的 OnConnected 方法:
public void onConnected(@Nullable Bundle bundle) {
//start the service
//checking and asking for permission
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
MY_PERMISSION_ACCESS_FINE_LOCATION);
}
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
Location location = LocationServices.FusedLocationApi.getLastLocation(mApiClient);
if (location == null) {
LocationServices.FusedLocationApi.requestLocationUpdates(mApiClient, mLocationRequest, this);
} else {
//If everything went fine lets get latitude and longitude
currentLatitude = location.getLatitude();
currentLongitude = location.getLongitude();
Log.v("currentLatitude",currentLatitude + " WORKS " + currentLongitude + "");
}
}
您可能需要在 build.gradle 中添加依赖项:
compile 'com.google.android.gms:play-services-location:10.0.1
试试这个代码:
private LocationCoord gps = null;
private static final int PERMISSION_REQUEST_CODE = 1;
在 OnCreate() 中:
//GPS Manage
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
boolean gps_enabled = false;
boolean network_enabled = false;
try {
gps_enabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
} catch (Exception ex) {
}
try {
network_enabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch (Exception ex) {
}
if (!gps_enabled && !network_enabled) {
// notify user
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.setMessage("Allow ImHere to access this device's location?");
dialog.setPositiveButton("Allow", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(myIntent);
//get gps
}
});
dialog.setNegativeButton("Deny", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
// TODO Auto-generated method stub
}
});
dialog.show();
}
gps = new LocationCoord(this);
@Override
protected void onStart() {
super.onStart();
// permission android 6.0
if (!checkPermission()) {
requestPermission();
}
}
private boolean checkPermission(){
int result = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
if (result == PackageManager.PERMISSION_GRANTED) return true;
else return false;
}
private void requestPermission(){
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, PERMISSION_REQUEST_CODE);
}
您将需要对 Manifest.xml 的此权限:
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
