REQUEST_IGNORE_BATTERY_OPTIMIZATIONS how to do it right

Question

I have IntentService task in foreground mode, but in Android M+ the task stops in Doze mode. I read Google banned if the app uses intent to set themselves in whitelist. But if I use permission and check GRANT or DENIED, I get the granted result, but nothing happen. I don't see my app in whitelist. How can I add the app in whitelist without banned? (I added permission in AndroidManifest.xml)

if(Build.VERSION.SDK_INT>=23){
    int permissionCheck= ContextCompat
                    .checkSelfPermission(this, Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);

    if(permissionCheck == PackageManager.PERMISSION_DENIED){

        //Should we show an explanation
        if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)){
            //Show an explanation
            final String message = "";
             Snackbar.make(coordinatorLayoutView,message,Snackbar.LENGTH_LONG)
                     .setAction("GRANT", new View.OnClickListener() {
                         @Override
                         public void onClick(View v) {
                             ActivityCompat.requestPermissions(MainActivity.this, new String[]{ Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS }, PERMISSION_REQUEST_CODE);
                         }
                     })
                     .show();

                }else{
                    //No explanation need,we can request the permission
                    ActivityCompat.requestPermissions(this, new String[]{ Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS }, PERMISSION_REQUEST_CODE);
                }
            }
        }

Solution 1

REQUEST_IGNORE_BATTERY_OPTIMIZATIONS is not a dangerous permission. You do not need, or want, any of that code. Quoting the documentation for REQUEST_IGNORE_BATTERY_OPTIMIZATIONS:

Permission an application must hold in order to use ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS. This is a normal permission: an app requesting it will always be granted the permission, without the user needing to approve or see it.

So, delete all that code.

I don't see my app in whitelist.

That is because the user did not add you to the whitelist, apparently.

Requesting REQUEST_IGNORE_BATTERY_OPTIMIZATIONS grants you the authority, from a security standpoint, to start an activity with an ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS Intent. Be sure to include your app's package as the Uri:

startActivity(new Intent(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS, Uri.parse("package:"+getPackageName())));

The user will be taken to a screen where they can indicate that they are willing to suspend portions of Doze mode effects on your app.

How can I add the app in whitelist without banned?

If you do not want to be banned, do not do any of this. Have something in your app that starts an activity with an ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS Intent. This leads the user to the overall list of apps, where the user can toggle which ones are and are not on the whitelist. This does not require any permission.

The act of requesting REQUEST_IGNORE_BATTERY_OPTIMIZATIONS in the manifest is what may get you banned.

Be aware of using Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS intent for the activity, this does not work on all phones and you will get a android.content.ActivityNotFoundException. In particular it does not work on Samsung phones running Android 6. The only combination that I have found works on these phones is to declare the REQUEST_IGNORE_BATTERY_OPTIMIZATIONS in the manifest, then launch an activity with intent Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS. I.e. the combination that is not liked by Google.
