How to check permission while creating android app .

 While running app, some app initially or button click it will ask for allow or deny permission for example, allow camera, allow microphone, allow camera, allow location .

for this use simply do the following steps:

step 1 ) AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />  for internet permission

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"  /> write permission

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />  read permission

<uses-permission android:name="android.permission.CAMERA" />  for camera

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>  for access location

Step 2 ) go to Mainactivity.java or wherever you want to ask permission add below code

declare variable as, private static final int STORAGE_PERMISSION_CODE = 101;

call method , checkPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE, STORAGE_PERMISSION_CODE);

define function,

 public void checkPermission(String permission, int requestCode)

{

if (ContextCompat.checkSelfPermission(MainActivity.this, permission) == PackageManager.PERMISSION_DENIED) {

// Requesting the permission

ActivityCompat.requestPermissions(MainActivity.this, new String[] { permission }, requestCode);

}

else {

Toast.makeText(MainActivity.this, "Permission already granted", Toast.LENGTH_SHORT).show();

}

}

@Override

public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

super.onRequestPermissionsResult(requestCode, permissions, grantResults);

if (requestCode == STORAGE_PERMISSION_CODE) {

if (grantResults.length > 0

&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {

Toast.makeText(MainActivity.this, "Storage Permission Granted", Toast.LENGTH_SHORT).show();

}

else {

Toast.makeText(MainActivity.this, "Storage Permission Denied", Toast.LENGTH_SHORT).show();

}

}

}

above is example storage permission ask, in the similar way other permission will work.

how to get geolocation with latitude and longitude

 ask browser to allow location

function getLocation() {

  if (navigator.geolocation) {

    navigator.geolocation.getCurrentPosition(showPosition);

  } else { 

    x.innerHTML = "Geolocation is not supported by this browser.";

  }

}

using position.coords.latitude & position.coords.longitude we can get exact position in map

useful when adding google map to website or app, also track geolocation

no any other script or file required.

<!DOCTYPE html>

<html>

<body>

<p>Click the button to get your coordinates.</p>

<button onclick="getLocation()">Try It</button>

<p><strong>Note:</strong> The geolocation property is not supported in IE8 and earlier versions.</p>

<p id="demo"></p>

<script>

var x = document.getElementById("demo");

function getLocation() {

  if (navigator.geolocation) {

    navigator.geolocation.getCurrentPosition(showPosition);

  } else { 

    x.innerHTML = "Geolocation is not supported by this browser.";

  }

}

function showPosition(position) {

  x.innerHTML = "Latitude: " + position.coords.latitude + 

  "<br>Longitude: " + position.coords.longitude;

}

</script>

</body>

</html>
