Hi all.
The code below works fine on a lot (tenth) of devices. It shows the settings panel to prompt the user to exclude the app from the Android battery optimization.

B4X:
    If GetAndroidApiLevel>=23 Then
        Dim JavaObject1 As JavaObject
        JavaObject1.InitializeContext
        Dim Ignoring As Boolean=JavaObject1.RunMethod("isIgnoringBatteryOptimizations", Null)
        If Ignoring=False Then
            Msgbox("Please confirm the following form to exclude the app from battery optimization.", "Battery optimization")
            'RuntimePermissions1.CheckAndRequest("android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS")
            Dim JavaObject1 As JavaObject
            JavaObject1.InitializeContext
            JavaObject1.RunMethod("ShowPermissionDialog", Null)
        End If
    End If


#If JAVA
import android.content.Context;
import android.content.Intent;
import android.os.PowerManager;
import android.provider.Settings;
import android.net.Uri;
import anywheresoftware.b4a.BA;

public boolean isIgnoringBatteryOptimizations(){
Context context=this;
String packageName = context.getPackageName();
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
return pm.isIgnoringBatteryOptimizations(packageName);
}

public void ShowPermissionDialog(){
    Intent intent = new Intent();
    Context context=this;
    String packageName = context.getPackageName();
    PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    if (pm.isIgnoringBatteryOptimizations(packageName)){
        BA.LogInfo("isIgnoringBatteryOptimizations TRUE");
        intent.setAction(Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS);
    } else {
        BA.LogInfo("isIgnoringBatteryOptimizations FALSE");
        intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
        intent.setData(Uri.parse("package:" + packageName));
    }
    context.startActivity(intent);
}
#End If

But on a Huawey P9 (API level 23) it crashes:

~e:Caused by: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS dat=package:it.elettronicablancato.bmap4aw }

Any idea ?

I tried to implement the code however it seems as I dont have the required library for GetAndroidApiLevel.
How do I fix this?
For the future.
- ALWAYS create a new thread for ANY question you have
- NEVER post to existing threads to add a question.

B4X:
    Dim p As Phone
    Log(p.SdkVersion)

I Am strongly recommending to all of you to implement The following Java code. It will allow you to recall simple form of ignoring battery optimisation app, not all apps. Only buttons OK or Storno. Code is The part of Termux terminal emulator for Android. Termuxservice.java module.
String packageName = getPackageName();
if (!pm.isIgnoringBatteryOptimizations(packageName)) {
Intent whitelist = new Intent();
whitelist.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
whitelist.setData(Uri.parse("package:" + packageName));
whitelist.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

try {
startActivity(whitelist);
} catch (ActivityNotFoundException e) {
Logger.logStackTraceWithMessage(LOG_TAG, "Failed to call ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS", e);
}
}
