Do Android have any way to instantiate objects without calling any of its constructors? In Java, Sun have sun.reflect.ReflectionFactory.getReflectionFactory().newConstructorForSerialization(), in .Net we have System.Runtime.Serialization.FormatterServices.GetUninitializedObject() but I was not able to find anything like that in the Android platform.

The FAQ mentions a method of passing objects around activities. (It is not clear to me): "A HashMap of WeakReferences to Objects. You can also use a HashMap of WeakReferences to Objects with Long keys. When an activity wants to pass an object to another activity, it simply puts the object in the map and sends the key (which is a unique Long based on a counter or time stamp) to the recipient activity via intent extras. The recipient activity retrieves the object using this key.".................
View 7 Replies View RelatedI have an application that have a Google map on Google Android 1.5 since we have been working on the application for a long time, we are not in stage of upgrading to the newest framework, so we are using 1.5. Now, I have map locations that are dynamically generated and drawn on the map at run-time to visualize some streams, Up to this point the application is working fine, Now my problem is that I am trying to filter the objects ( addresses) to visualize only the on-screen ones. I do NOT want to visualize the addresses that are off-screen. The way I am trying to do this is to check the screen-coordinates of each object (address) before visualizing it, then it the coordinates (x,y) more than (0,0) and less than (320, 460). I should visualize it. I am trying to use this approach, but it is not working for some reasons, I have tried many posts but could not understand why, there must be something missing somewhere that I am not aware of.

View 2 Replies View RelatedIs is bad practice to pass the Context to a constructor and save it as a private variable for internal use? The other option is to pass the Context as a parameter to methods that need it.
Which is the better option?
I have a feeling that passing to the constructor might result in memory leaks accidentally.
Just getting started with developing for Android, so apologies if there's an obvious answer. I'm working on an application in which it's necessary to pro grammatically change the entire structure of the UI. What I would like to be able to do is specify a subtree of the UI in xml, and then instantiate that multiple times as required throughout the tree. For instance, if I need the user to set a numerical value, I'd like to use xml to define all the widgets involved, increment and decrement buttons for instance, and then reference this same file whenever I need a UI of that sort.

View 5 Replies View RelatedI'm interested in instantiating a LinearLayout object from an xml file that has a LinearLayout file configuration. I want to do this within a method of my Activity. I tried findViewById() but that returned null. I've made sure that the LinearLayout id is the one I'm passing. Note that this layout isn't part of my screen, it's stand-alone, so I want to build a LinearLayout object from the xml.
View 3 Replies View RelatedI have an application with a multi-instance activity. I would like each instance of the activity to appear in a new task and process. Any suggestions on how to do this? By manipulating the manifest I can cause all instances of the activity to appear in a specific task and
process, but I haven't found any way to cause each instance to appear in a different task and process.(The requirement to have different tasks is that we want each instance of the activity to appear separately in the task list; the requirement for different processes is that each instance of the activity is backed by a chunk of native code with global state. We can't change either of these.)

How To Bypass Android Lock Screen..What You Need:
- Your phone should be registered with a Gmail Account
Instructions:
- Download THIS App From Google Play Store From PC
- Now The App Will Be Installed On Your Registered Phone.
- Now Install Another App (ANY APP) From Play Store.
- Now The App You Just Downloaded Will Run And Screen Lock Will Be Disabled
Notes:
- This application will also run each time the device is booted so you can always bypass the lock screen.
- This application does not remove or reset your pattern/PIN, it only temporarily disables the lock screen so you can access your device and backup your data before resetting it.
Is there anyway to bypass 'Unknown sources' setting without having the application actually downloadable in the market? Signing up for the market is fine but I do not want the application actually available via the market due to partner restrictions. However, installation should be smooth without requiring the user to allow installation of application from non-market applications.

View 5 Replies View RelatedI am new to Android development. I want to know how you all manage objects. For eg we make object as A a = new A(); and then manage that object. But, here, we call A.class; My concern is that i don't want to call on Create(),nor do i want to push UI screen I just want to make 1 static object for 1 screen;and want to manage it throughout my application. that is, instead of calling A.class; can i call A a = new A(),and manage that object without pushing,and whenever i need i push that screen. Is there someway?

Ok, so why would I want/need to do this? Simple, I'm deployed to Iraq and my cell phone service is on a military suspense. I did a reset after the last update, and now cannot use the device until it's activated, or I find a way to bypass the activation.
What I've tried so far (thanks to Google):
-tried tapping the 4 corners, starting top left, going clockwise. Doesn't apply to this phone, but was still worth a shot.
-"end call" on activation 4-5 times
-reboot 3-4 times
i'm a computer forensics student who's trying to explore android forensic possibilities. I have compiled a module for testing devices (i have access to a Samsung S2 and a Galaxy Nexus running 4.1 and 4.0 respectively) in which i want to insert the module into the phone (i.e. insmod module.ko).
My problem is, i'm always faced with the problem of "insmod invalid module format" everytime i try to insert the module into the phone. I know that i can correct this by reflecting the appropriate kernel version in the vermagic string when i compile my module but i wanna find a generic way to do this; in other words, i wanna find a way to bypass this kernel version checking everytime i try to insert the module.
I've come across insmod having the -f flag as stated here (this would theoretically bypass the kernel version checking and i wanna verify this theory) insmod.

Is there a way to pass an Array List of objects between activities? The myObject implements Parcelable and I'm able to successfully pass the objects around individually, but that means I need to have an exact amount of "myObjects" coded. I want this to dynamically grow/shrink by what the user does with the app. I have seen some posts on the web about doing:
Activity A
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Then when passing this into the intent I would use:
intent.putParcelableArrayListExtra("myObjArray", myObjArray);
Activity B
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Bundle extras = getIntent().getExtras(); myObjArray = extras.getParcelableArray("myObjArray");
However, the myObjArray always gets filled with "null". How can I achieve this?
I want to pass an object from Activity B to Activity A. Scenario:
- Activity A calls Activity B
- User selects item in Activity B

I am new to this android stuff and SQLlite etc.I am going to log some numbers at a certain interval, and will put them into a dynamic histogram, by dynamic i mean that there will be a maximum number of samples in the histogram, the histogram and age stuff should be persisted either in db or plain file.For simplicity, I would like the samples to be stored in a blob type datafield, but i cannot se if this is possible. Alternative i could have another table with the samples Or I could simply have files with filename = name and content = samples.my concern might be unclear by now, but put simply, what is most effecient regarding power usage?
