android - requestPermissions() for gps inside a service . Error:"location provider requires ACCESS_FINE_LOCATION permission." -

-

the problem facing giving gps permissions application through service writing. tried finding example achieve , examples shows writing gpslocation finder in activity, in case, implement in service.

the service code follows: 

public class travelservice extends service{      private locationmanager locmanager;     private locationlistener loclistener;       @override     public void oncreate() {         super.oncreate();         locmanager = (locationmanager) getsystemservice(location_service);         loclistener = new locationlistener() {             @override             public void onlocationchanged(location location) {                 locmanager.requestlocationupdates("gps", 5000, 100, loclistener);              }              @override             public void onstatuschanged(string provider, int status, bundle extras) {              }              @override             public void onproviderenabled(string provider) {              }              @override             public void onproviderdisabled(string provider) {              }         };         if (build.version.sdk_int >= build.version_codes.m) {             if (activitycompat.checkselfpermission(this, manifest.permission.access_fine_location) != packagemanager.permission_granted && activitycompat.checkselfpermission(this, manifest.permission.access_coarse_location) != packagemanager.permission_granted) {                  // todo: consider calling                 //    activitycompat#requestpermissions                 // here request missing permissions, , overriding                 //   public void onrequestpermissionsresult(int requestcode, string[] permissions,                 //                                          int[] grantresults)                 // handle case user grants permission. see documentation                 // activitycompat#requestpermissions more details.                 return;             }             locmanager.requestlocationupdates("gps", 5000, 100, loclistener);              toast.maketext(this, "service created", toast.length_long).show();         }     }     @override     public int onstartcommand(intent intent, int flags, int startid) {         locmanager.requestlocationupdates("gps", 5000, 100, loclistener);          toast.maketext(this,"service started",toast.length_long).show();         return super.onstartcommand(intent, flags, startid);     }      @override     public void ondestroy() {         super.ondestroy();         toast.maketext(this,"service destroyed",toast.length_long).show();     }      @nullable     @override     public ibinder onbind(intent intent) {         return null;     }  }

here code in manifest.xml:

    <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.param.dateandtime">     <uses-permission android:name="android.permission.internet"/>     <uses-permission android:name="android.permission.access_fine_location"/>     <uses-permission android:name="android.permission.access_coarse_location"/>     <application         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:supportsrtl="true"         android:theme="@style/apptheme">         <activity android:name=".mainactivity">             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>         <!--  entry loginactivity.class -->         <activity android:name=".loginactivity"             android:label="@string/app_name"></activity>         <activity android:name=".finish"             android:label="@string/app_name"></activity>         <service android:name=".travelservice"             android:exported="false"/>     </application>  </manifest>

here have attached error log, showing error i'm facing. can see error "location provider requires access_fine_location permission." error log:

you cannot request permissions service since service not tied ui. activity when startservice().

activitycompat.requestpermissions(this,new string[]{manifest.permission.access_fine_location, manifest.permission.access_coarse_location}, 1001); //any number can used

and implement onrequestpermissionsresult() callback

 @override     public void onrequestpermissionsresult(int requestcode, @nonnull string[] permissions, @nonnull int[] grantresults) {         super.onrequestpermissionsresult(requestcode, permissions, grantresults);         switch (requestcode) {             case 1001: {                 if (grantresults.length > 0                         && grantresults[0] == packagemanager.permission_granted                         && (activitycompat.checkselfpermission(getactivity(), manifest.permission.access_fine_location) == packagemanager.permission_granted                         || activitycompat.checkselfpermission(getactivity(), manifest.permission.access_coarse_location) == packagemanager.permission_granted)) {                     //start service here                 }             }         }     }
