Hi!

I would like to set some of settings od phone/device programatically.

As far as I could get, was getting this flags, that needs to be changed:
0x18404000
0x18004080
0x18005001

I am doing this in correct way or am I missing something?

Second...
0x18004080,"java.lang.int"... I know that this is wrong. Can you please advise me how to change it?

B4X: 
Dim obj1 As Reflector
'obj1.Target = obj1.GetActivity
obj1.Target = obj1.GetMostCurrent(ActivityName)
obj1.Target = obj1.RunMethod("getWindow")


obj1.RunMethod2("addFlags",0x18004080,"java.lang.int")    
'obj1.RunMethod2("clearFlags",0x18004080,"java.lang.int")

Thank you!

I am trying to set system settings. Do I have to open that windows/dialog first? What to put in ActivityName?

With this code: screen goes blank and java.lang.NullPointerException occurs.

Among other... HTC has Home dialing menu "com.android.htcdialer/.HomeDialingActivity"

I am trying to figure this out. I focused on trying to set Auto-rotate screen that.

On this page the solution is for Java:
button - Set Auto-Rotate Enabled/Disabled Android - Stack Overflow

B4X: 
android.provider.Settings.System.putInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0);
android.provider.Settings.System.putInt(getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 1);

Can this be translated for B4A? I am looking to set several setting. I can not find which numbers to run in RunMethod2 "addFlags".


If I change Auto-rotate manually, this is shown in logs:

Here's a library class i used recently in a project:

B4X: 
package uk.co.martinpearman.b4a.rotationmanager;

import android.content.ContentResolver;
import android.provider.Settings;
import android.provider.Settings.SettingNotFoundException;
import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.Author;
import anywheresoftware.b4a.BA.Permissions;
import anywheresoftware.b4a.BA.ShortName;
import anywheresoftware.b4a.BA.Version;

@Author("Martin Pearman")
@Permissions(values = { "android.permission.WRITE_SETTINGS" })
@ShortName("RotationManager")
@Version(1.00f)
public class RotationManager {

   public final static int ACCELEROMETER_ROTATION_DISABLED = 0;
   public final static int ACCELEROMETER_ROTATION_ENABLED = 1;
   public final static int ACCELEROMETER_ROTATION_ERROR = -1;

   public static int GetAutoRotateEnabled(BA pBA) {
      ContentResolver contentResolver = pBA.context.getContentResolver();
      String name = Settings.System.ACCELEROMETER_ROTATION;
      try {
         return Settings.System.getInt(contentResolver, name);
      } catch (SettingNotFoundException e) {
         e.printStackTrace();
         pBA.setLastException(e);
      }
      return ACCELEROMETER_ROTATION_ERROR;
   }

   public static void SetAutoRotateEnabled(BA pBA, int Enabled) {
      ContentResolver contentResolver = pBA.context.getContentResolver();
      String name = Settings.System.ACCELEROMETER_ROTATION;
      Settings.System.putInt(contentResolver, name, Enabled);
   }
}

RotationManager
  • RotationManager
    Fields:
    • ACCELEROMETER_ROTATION_DISABLED As Int
    • ACCELEROMETER_ROTATION_ENABLED As Int
    • ACCELEROMETER_ROTATION_ERROR As Int
    Methods:
    • GetAutoRotateEnabled As Int
    • SetAutoRotateEnabled (Enabled As Int)
    Permissions:

The library files and source are attached.

Martin.

Hi!
oh, this is great. Thank you very much.
I guess most of the settings I could set like this. Problem is getting settings name. This are that I found: Settings.System | Android Developers

Does anybody know where are lists for custom settings for like HTC, Samsung?

Have a nice day!

Click to expand...

I'd suggest looking on the HTC and Samsung websites - look for any development SDKs they have available.
There might be documentation included in the SDK that documents device specific settings.

Thats the point... You are setting/changing SYSTEM-SETTINGS... So this has affects on other apps too. If you ONLY YOUR APP to be in a certain orientation then you can add

SetActivityAttribute(main,android:screenOrientation, "sensorLandscape")
Click to expand...

in the b4a-manifest-editor. You must put a line in manifesteditor for EACH activity... In this example i posted the code for activity "Main".
this changes only affects your app. precisely it affects only the named activity(s) from your app.

so maybe you can limit yourself. Or say in other words. Maybe you can put all Features which uses a specific orientation into on or more specific activitys... With the code above you can select which activitys you want to set to landscape for example....

Example:
Act Main: Normal behaviour is to change orientation if user change it... Like any other app
Act specialfeaturesinlandscapp: all landscape features here. This activity get the code i posted...
Act somethingother: Normal....
