I edit some code to making an application to get mobile data its basic information. I am facing too issues.
- Permissions are asked 3 times.
App is crashing in marshmallow on first launch with error of permission not for
access_coarse_location. Advice how to fix the problem and what wrong is with this code.<uses-permission android:name="android.permission.SEND_SMS" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <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> </application>import android.Manifest; import android.annotation.TargetApi; import android.app.Activity; import android.content.Context; import android.content.DialogInterface; import android.content.Intent; import android.content.pm.PackageManager; import android.os.Build; import android.os.Bundle; import android.os.PersistableBundle; import android.support.v4.app.ActivityCompat; import android.support.v4.content.ContextCompat; import android.support.v7.app.AlertDialog; import android.support.v7.app.AppCompatActivity; import android.telephony.CellLocation; import android.telephony.TelephonyManager; import android.view.View; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; public class MainActivity extends AppCompatActivity { private static final int REQUEST_PERMISSION = 1; //Declaring View Object public TextView Info; public Button Refreshbtn; @TargetApi(Build.VERSION_CODES.M) @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Refreshbtn = (Button) findViewById(R.id.Refresh); Refreshbtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { DeviceData(); } }); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { //Toast.makeText(this, "It is M Version", Toast.LENGTH_SHORT).show(); Askpermission(); } else { // Toast.makeText(this, "it is below M", Toast.LENGTH_SHORT).show(); DeviceData(); } } private void Askpermission() { List<String> permissionlist = new ArrayList<String>(); List<String> permissionneeded = new ArrayList<String>(); if (addPermission(permissionlist, Manifest.permission.ACCESS_COARSE_LOCATION)) permissionneeded.add("Location"); if (addPermission(permissionlist, Manifest.permission.ACCESS_FINE_LOCATION)) permissionneeded.add("Location"); if (addPermission(permissionlist, Manifest.permission.SEND_SMS)) permissionneeded.add("Send SMS"); if (addPermission(permissionlist, Manifest.permission.READ_PHONE_STATE)) permissionneeded.add("Read Phone Info"); if (permissionlist.size() > 0) { if (permissionneeded.size() > 0) { for (int i = 1; i < permissionneeded.size(); i++) ActivityCompat.requestPermissions(this, permissionlist.toArray(new String[permissionlist.size()]), REQUEST_PERMISSION); } return; } DeviceData(); } @Override public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { switch (requestCode) { case REQUEST_PERMISSION: { Map<String, Integer> perms = new HashMap<String, Integer>(); // Initial perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED); perms.put(Manifest.permission.READ_PHONE_STATE, PackageManager.PERMISSION_GRANTED); perms.put(Manifest.permission.SEND_SMS, PackageManager.PERMISSION_GRANTED); perms.put(Manifest.permission.ACCESS_COARSE_LOCATION, PackageManager.PERMISSION_GRANTED); // Fill with results for (int i = 0; i < permissions.length; i++) perms.put(permissions[i], grantResults[i]); // Check for ACCESS_FINE_LOCATION if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.SEND_SMS) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED && perms.get(Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED) { // All Permissions Granted DeviceData(); } else { // Permission Denied Toast.makeText(MainActivity.this, "Some Permission is Denied", Toast.LENGTH_SHORT) .show(); } } break; default: super.onRequestPermissionsResult(requestCode, permissions, grantResults); } } private boolean addPermission(List<String> permissionlist, String permission) { if (ContextCompat.checkSelfPermission(MainActivity.this, permission) != PackageManager.PERMISSION_GRANTED) { permissionlist.add(permission); } return true; } public void DeviceData() { Info = (TextView) findViewById(R.id.Info); //Creating object to use TelephonyManager Class methods to get required data.
