I was looking 2 weeks ago for sending back and home key events when on Click is performed on a Image Button, I could do that perfectly. I have a device with no buttons. So, I want to simulate Menu button click. To know what is really happening, I implemented a code in on Create Options Menu that rises a Null Pointer Exception. I got the following stack trace. code...

Is there any way for an ordinary application to replace low level classes that are preloaded on startup, so that higher level preloaded classes will end up calling my custom versions rather than the originals?
I'm thinking the answer is no, but want to make sure I haven't overlooked something.
I am currently working on porting a application written in C in android platform. I need to know that can i invoke/call the getSystemService from the C application using invocation interface by JNI. Meaning using a .java file which will interact with the interace provided by the android.telephony.TelephonyManager.java for using getCallState() and other mehthods.

I want to keep launching my app and stress test two scenarios: launch it and press BACK key launch it and press MENU key I can launch from adb using "am" command. But how can I send a BACK or MENU key using adb. I want to do thousands of rounds of testing so I don't want to do it manually.

View 2 Replies View RelatedMy Activity using transparent Theme in AndroidManifest.xml *android:theme="@android:style/Theme.Translucent"* Which works fine. When it's started from the Home screen, we can see both the content of my activity and the home screen below it. It gives the feeling of "floating". Furthermore, to make it real "floating", the motionEvent has to go down to the home screen to let the home screen response some motion touch. But I have no idea of 2 things : 1. Whether the event can be send down to any thing behind the current activity. 2. If so, how. The solution don't need to be restricted in API level.I mean if any solution need us to rewrite home screen or something else, It's also ok for me.

View 1 Replies View RelatedI'm having trouble developing an app, while it works in API level 10, it does not in API level 7. I wondery why and I've been looking for a site that summarizes the differences, or the new features from one API level to another and cannot find it.

I know that the apps receive a ACTION_SHUTDOWN broadcast event when the device is shutting down.
When an application receives the shutdown, is there still an opportunity to send data packets out, or does android block such attempts(or does the platform tear down the network stack before it can go out).
I'm looking into writing simple graphics code in Android and I've noticed some synchronized() blocks. What is the reasoning behind this and how do I know when I should be "synchronizing" my code?

View 2 Replies View RelatedI have a brand new Desire HD. Up until 2 days ago, everything was working perfectly with my Outlook Exchange Account on the native Android Mail application. Running Android 2.2
Since then, there is something wrong with our Outlook certificate, and when I launch Outlook on my PC, I get a message that the name on the certificate is not valid. Ok, fine. So on the PC, I press "OK" and I am off and running.
On the Desire, I still get email, but if I try to SEND and email, it neither reaches the recipient, nor does the email end up in the "Sent" mail folder. When I go to "Accounts and Sync" and look at the Exchange account, I also see that i have a sync protocol error on Contacts syncing.
Now, I have installed Touchdown, and I CAN send email from here. Also, I have a friend who has an older Android phone that does not seem to be affected in a similar fashion connecting to the same exchange server.
Problem: The Touchdown app is kind of a pain from a user interface standpoint when you try to edit a contact. and it costs $20. And, I really prefer the native Mail widgets and stuff.
I am stuck using Touchdown at the moment so that I can send and receive emails, but I am hoping to find a workaround. Our IT people are working on the certificate problem, so maybe that will help. HOWEVER, I cannot afford to be without email every time there is a certificate problem.

View 7 Replies View RelatedI have written a number of applications for blackberry and am just starting in Android. It seems to me that android has a lot more built in functions. I am starting by recreating some of my BB apps on Android and on one I take a few xml sites and parse them out. On blackberry I implemented this by creating a class that extended a thread. I would construct a new instance of this class with the parameters of my http request and it would call a function back in my main class, sending it the results. I am tempted to reuse my code, but am curious if android has something better built in. I have been looking at the handler class as well as possible using a service.
Bascially, I would like to start a new thread that will return a document of a specific url.
I have two applications A and B (in different packages,but it doesn't matter).Application B is an sms application that i have made and contains one activity.This activity has a method called sendSMS(String number,String text).I want to call this method from application A and send an SMS without opening the activity(the GUI) of application B but just send an SMS in the background by calling just the method of the activity.Any ideas?

View 2 Replies View RelatedSo I'm writing an Android app which uses a large c++ library. I have everything working so that the java app can call the c++ delegation methods, but I'm finding myself wishing I could log messages from c++ to the Android log. This is easy from java, but I'm at a loss as to how to call a java method from c++. My searches found methods for opening a jvm from c++, which is not at all what I want to do. Ideally, I'd like to pass a log method pointer to c++, which could then be used whenever I wanted. Of course, java doesn't support method pointers.
View 2 Replies View RelatedI have a MapView where I would like to be able to tap the map to create a new item at that location if there is no item there, or display the info about the item if there is.
I tried overriding both the onTap(int) and onTap(GeoPoint, MapView) methods but apparently if the second method is overridden the first never gets called (commenting one or the other lets each one work as I expected).
I thought about just checking if an item was at the location, but there doesn't seem to be any handy methods available to do that (other than iterating through the list of items and checking each manually).
