Android Question [solved]How to write in B4A: mContext.getContentResolver().call()

flylg999 said:

The java code is :

Java:

CONTENT_URI_SWITCH_SYSTEM = Uri.parse("content://com.xdja.switchsystem.assistantprovider")

 Bundle bundle = new Bundle();
 bundle.putBoolean("is_switchable", p0);
 mContext.getContentResolver().call(CONTENT_URI_SWITCH_SYSTEM, "setSwitchable", null, bundle);

Can anyone help me in using it in B4A,Thanks a lot!

The simplest way is to use inline java and then call it by javaobject.

You can probably do it with JavaObject.
Dim ctx As JavaObject
ctx.IntializeContext
ctx.RunmethodJO("getContentResolver", Null).Runmethod("call", array.......

Something like the above I guess.
Not sure in what class CONTENT_URI_SWITCH_SYSTEM is - you might need to use another javaobject to get access to the enum field.

Using JavaObject try:

B4X:

' Create the JavaObject for Uri
Dim Uri As JavaObject
Uri.InitializeStatic("android.net.Uri").RunMethod("parse", Array("content://com.xdja.switchsystem.assistantprovider"))

' Create the Bundle
Dim bundle As JavaObject
bundle.InitializeNewInstance("android.os.Bundle", Null)
bundle.RunMethod("putBoolean", Array("is_switchable", p0))

' Get the ContentResolver and call the method
Dim mContext as JavaObject
mContext.initializeContext
Dim contentResolver As JavaObject
contentResolver =mContext.RunMethod("getContentResolver", Null)
contentResolver.RunMethod("call", Array(CONTENT_URI_SWITCH_SYSTEM, "setSwitchable", Null, bundle))

CONTENT_URI_SWITCH_SYSTEM has to be defined whether a constant or part of an enumeration.
