Android Question REQUEST_IGNORE_BATTERY_OPTIMIZATIONS problem

[marcick]

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.

    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:

Any idea ?

Problem disappeared after a system update (Huawey) ...

any suggestions?

You should use a more recent version of android.jar under Tools - Configure Paths.

any suggestions ?

I copied and pasted this code, starting the function in Activity_Create
nothing happens, I display the MsgBox but pressing OK does not show the dialog to ignore battery optimization
nothing happens, no errors

I have tired Huawey P10 Plus and Nexus 5X

 

[FabioG]

added
AddPermission(android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)
on manifest editor
and it work great

Thanks

I tried to implement the code however it seems as I dont have the required library for GetAndroidApiLevel.
How do I fix this?

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);
}
}
