I'm dealing with android app permissions in which if the user denied permission permanently I need to move the user to app Settings to enable the permission manually. All the code working fine but when I start an Intent to move the user to Settings of my app I'm getting activity not found Exception.
Here is the Exception
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.APPLICATION_DETAILS_SETTINGS dat=Package:com.e.permisions }
This is my code
package com.e.permisions;
import androidx.annotation.NonNull;
import androidx.appcompat.app.AlertDialog;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import android.Manifest;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.provider.Settings;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
Button request;
String[] permissions = {Manifest.permission.READ_EXTERNAL_STORAGE};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initilising buttons
request = findViewById(R.id.request);
request.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.READ_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
//Todo: Code to do what if permissions granted...
Toast.makeText(MainActivity.this, "Permissions Granted", Toast.LENGTH_SHORT).show();
} else {
if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE)) {
//Todo: usually we should show alert why should need these permissions...
new AlertDialog.Builder(MainActivity.this)
.setTitle("Why these Permissions?")
.setMessage("For App functionality we need these permissions..")
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
})
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//Todo: request permissions when click ok
ActivityCompat.requestPermissions(MainActivity.this, permissions, 123);
}
})
.setCancelable(false)
.create().show();
} else {
//Todo: request permissions
ActivityCompat.requestPermissions(MainActivity.this, permissions, 123);
}
}
}
});
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 123) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//Todo: code to do what if permissions are Granted...
Toast.makeText(this, "Permissions are Granted", Toast.LENGTH_SHORT).show();
} else if (!ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.READ_EXTERNAL_STORAGE)) {
//Todo: if permissions Denied permanently by user..
gotoSettings();
} else {
//Todo: what to do if denied
Toast.makeText(this, "Permissions Denied", Toast.LENGTH_SHORT).show();
}
}
}
private void gotoSettings() {
new AlertDialog.Builder(this)
.setTitle("Go to Settings")
.setMessage("enable the permission")
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Toast.makeText(MainActivity.this, "Moving to Settings", Toast.LENGTH_SHORT).show();
try {
Intent intent = new Intent();
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts("Package", getPackageName(), null);
intent.setData(uri);
startActivity(intent);
} catch (Exception e) {
Toast.makeText(MainActivity.this, "failed to open Settings\n" + e, Toast.LENGTH_LONG).show();
Log.d("error", e.toString());
}
}
}).create().show();
}
}
Also updates permission details in the manifest file. Anyone can help what's going wrong with this code.
Thanks in advance.
The issue is you are giving "Package" in
Uri uri = Uri.fromParts("Package", getPackageName(), null);
Because of the case sensitivity it is not finding the view, Try giving package
as given
Uri uri = Uri.fromParts("package", getPackageName(), null);
